sir, thank u so much sir. ur project working nice with good response. i can 't say any more words to appreciate what u have done in this machine vision based robot sir.
Hey im having trouble understanding what you used to identify the colors, is it a camera on the car or separate? did you include any color sensors or how does this work?
Hello, I used OpenCV library that runs on the Android device through the app that we use. The app uses phone's camera to acquire image needed by the library to run image processing task, all embedded in the app. No color sensors or other sensors were used. The app is even capable of using the phone's internal sensor such as the compass module to guide it's heading direction. Hope this helps a bit. Thanks!
Thanks, this was the most fun use of the 4wd robot videos. Just an idea - it might be possible to use more simple sensor for color detection; there are color sensor modules. That would be less accurate as with smartphone but at least less dangerous to play with (nobody wants to accidentally hit their phone while playing with a robocar :D)
I'm using L293d motor driver shield which has only two motor outputs. And the thing is I'm applying this application to an RC car which has 2 motors : one for the direction controll and other for acceleration. I need Bluetooth output produced by your application depending on the situation so that i can write a code for arduino in a way that it will controll 2 motor's. Please Help !
links given in (Updated on 30 November 2018) are working properly .I completed my project successfully I used separate serial port (pin 11 12) and pins which is not a big deal anyone can use as per their conv. ( So anybody can use above sources without any doubt) and finally THANKS A LOT "NUDGE ME"
I managed to replicate this project with some changes, however I would like to know how I could stop the vehicle if the object is in front of it and it does not move to a specific range so that it does not move unless I move
Hi! First off, this is so cool and I love your videos! We are trying to use this app and code to build a robot that follows a person around and the app keeps on crashing when we try to connect to a bluetooth receiver. We are using a Samsung Galaxy S5 phone and an HC-05 bluetooth receiver. We also charged the battery and tried. We had everything functioning until yesterday and today it is randomly crashing. We tried factory re-setting the phone, re-downloading the software, and stopping all the other apps and still nothing is working. Do you have any idea what could have gone wrong? (This is kind of urgent because we are using this app on a project that is due in the next day so we would really appreciate a quick response!)
Hi, thanks for your interest in my projects. So weird, normally the failure would happen on the robot side, such as Bluetooth connection suddenly disconnected and so on. Try this: Just connect 3 wires from the Arduino to the Bluetooth module which they are: Arduino's 5V -> BT's VCC Arduino's GND -> BT's GND Arduino's RX -> BT's TXD Don't connect the Arduino's TX to the Bluetooth's RXD pin and see the result.
Abg, nk tumpang tnya. Sya ada try download kan Obstacle Avoidance function link yg abg bagi tetapi file dia .1, mcm mana nk gunakan sebenarnya? sya kurang faham sbb sya ingin nk buatkan satu project yg lebih kurang mcm abg punya tapi utk collectkan ping pong balls. hanya akn ada tambahan stepper motor sbg scoop utk sapu kan bola ke satu container dlm kereta binaan sekali dgn ultrasonic sensor utk avoid langar dinding melainkan v2.1 tak mengunakan ultrasonic sensor??
You can use 4 AA batteries which will make it be 4 x 1.5 = 6V or one 9V battery or 2 Li-Ion 18650 batteries which will make it be 2 x 3.7 = 7.4V. Thanks!
+amiskapinga Yes, but the robot needs to be mounted with RFID reader then. And keep in mind, the RFID works when both of the tag and reader are close in range, so the robot may need to go 'sniff' the tag to read it.
Excuse me Mr. Nudge Me, but I am currently trying to do this project for my Grade 6 science fair. I used the Motor shield in your video, I followed your blueprints, but when I used the app and pressed start, the way the code is interacting with the motors, or motor shield driver is strange. It only moves for 0.1 seconds when i move the ball. Can you send a tutorial on how to use the app or on how you built the robot? Thanks a lot for this project.
Hello, thanks for your interest in my project. Strange, did you follow all the steps suggested in the video description above? I paste it again here: 1. On Page 1, click on BALL button. Then click on / symbol next to the BALL button. 2. Point the camera to the object colour you want to detect, then tap on that object's image. The app will highlight the object detected. 3. If you are satisfied with the detection coverage, click OK button. If not, adjust the detection quality by playing around 3 values in the red boxes located at the bottom left of the screen (the red boxes only appear after you click BALL button, and will be hidden when you click OK button). The green numbers inside the red boxes denote the values for HSV's range. You can also adjust the HSV values themselves by pressing the Range button (located next to the yellow box beside the OK button), and when it turns to yellow, the HSV values will be shown. Normally, we don't really need to adjust the Range and HSV values as the app will automatically set the best values every time we tap on the object's colour we want to detect. 4. Press Lock AE (lock auto exposure) and Lock WB (lock white balance) to make sure those parameters are reserved even when the surrounding lighting changes. 5. The label Comb. on the Comb. button will make the app combine all the same colours into one COG (center of gravity). If you want the app detect the largest blob, press on it until it display Larg. Else if you want the app to detect your desired colour separately, click on it again until it display Sepa. 6. If everything is OK, press OK. If you want to edit the detection parameters again, just press on the BALL button again. 7. Go to Page 2, increase Rot. speed (rotational speed) and Pref. speed (preferred speed) as you wish and click START button to make your robot move. Press STOP button to make it stop. After following all the steps above your robot still doesn't move? Or on which specific step you did face the problem?
@@nudgeme4844 Hi Mr Nudge Me, thank you very very much for responding to my queries. I will follow the steps that you have given and I will update you on my progress very soon. I am keeping my fingers crossed. Thank you sir
I did all the connection and able to part the bluetooth , but the movement of the robot seem weird . later I post up my video. what a great project by you .
Thanks for making open source.... I built this robot and it's basically working with some issues.... it can follow the red ball but it has to be very very slow or it looses the ball and hits another object.... in your opinion is this the phone or version of openCV manager... The Arduino code seems to work flawlessly. If you move the ball out of the cameras sight it can easy loose track unless you are at least 1.5M away and very slow... Thanks
Hi, the lag may be caused by the phone. FYI, not all high end phones can handle the image processing in a fast way. For example, Samsung Note 2 surprisingly can perform better than Samsung Note 4 and most of the Huawei, Oppo and Vivo phones. The algorithm should make the robot turns to the last sight of the ball before it loses track, for example it will turn left if it loses ball at the left of its sight. Thanks for your comment :)
I suspected the phone it's a cheap infocus phone that my wife said was crap and it is so I used it in this project... instead of using a ball I'll use something slower like a red target on my cat.. give the little cat some exercise..haha.. thanks for the reply... Do you have any new projects in the pipe line?
hi plz in your code SoftwareSerial mySerial(A2,A3); // Connect the TXD pin of BT module to pin A2 of the Arduino (or the L293D motor shield). The RXD pin of BT module and A3 of Arduino can be left unconnected. YOU connect tx to A2 and RX to A3
Hi projects are very good and thank you for these projects. I did this project with my son, but opencv manager does not work on my phone samsung s6 + edge. I have downloaded opencv manager from Google play but I don't detect Color Tracking App (Ver 4.6) can you help me please.. thank you
@@nudgeme4844 Thanks for answering. do not understand very application. Can you guide me and others through the video? The subject of the robot follows the white line thanks!
hey there nice work am using l298n motor driver and the code is not working are u sure that code can match both the joystick and the color tracking app
Yes, it should work on both joystick and color tracking app. make sure you select the correct mode on the joystick app through the menu, which is 2wd/4wd mode.
Hi Nudge Me! Your projects are awesome! Thank you so much for doing these and sharing them. We are using your project to help teach kids about Arduinos, robotics, and programming and they love it! You should be proud. I noticed there is an issue with trying to use the Color Chasing App on the Omni 3 Wheel versions. I believe it is linked to there being no ".'" case statement in the code to handle the "w" variable. Have you addressed this anywhere? I can share my revisions to your code if it will help, but I'm not certain I have modified it exactly correctly. Either way, all the kids, the professor, and myself are a huge fan of your work. I just wanted you to know that!
suman gupta Hi, refer pictures here: goo.gl/AkVLsP and here goo.gl/xZEvM6. Get the code here: goo.gl/YWJYfW. The circuit diagram is as shown here: goo.gl/57rckQ.
Hello sir, you have a wonderful project. I want to build one, but I have a request for the code in Rabat. They ask me to send you a message so that I can solve it, but you did not respond, and that is why I could not build it. Help me, please.
hi, thanks for this great project. i have tried alot and made this project with some of issue resolved but some left unresolved like i have increase the battery to 12v and 1amp, which power up and make car movable but the problem is that when ball move left or wright the car get it hard to rotate and sometimes it rotate and sometimes not
Hey, you need to set up the parameters that fit your robot. Goto Page 2 on the app, increase rotational speed by pressing + sign on the Rot. speed section. To make your robot go faster, try increase the Pref. speed value. Hope this helps. Thanks!
@@nudgeme4844 sir when the ball goes to left side then the car turns to left side & rotates correctly but when it comes to right side the car goes reverse side or car does not turn & get stopped.... And another thing in your video when you move your ball behind the car it fully rotates or take U-turn itself but when i move my red ball the car get stopped and doesn't move.... give reply as soon as possible i have to submit it...
Maybe your case is same with Malik's one. Goto Page 2 on the app, increase rotational speed by pressing + sign on the Rot. speed section. Press the + sign after you start your robot. Let the value increase until the robot turn successfully and stop the increment by pressing anywhere on the center of the screen. Hope this helps.
Hi man! I've done the same project as in your video. But the robot does not move though the app works well. I used a pin lipo 7.6v 3.8a power supply for arduino uno and 4 DC motors. Help me !!!
Hello! Try to check the connection to the Bluetooth module, RXD and TXD pin of BT module needs to go to the correct pins on the Arduino and the grounding of motor driver module and the Arduino should be common (connected together).
xy mode is actually sending the x and y coordinates of the tracking object to the Arduino while the 2WD/4WD will send the processed wheel speed values based on the location of the object. Maybe you used the Arduino code that processes the first option, not the second one.
It depends on what do you want the robot to do. If you want the output to be directly in the form of processed wheel speeds, then opt for the 2WD/4WD mode. But anything that is more than that such as decision making and etc would be beyond your control. On the other hand, if you choose the x and y output mode, you can do further decision making on your Arduino such as if the y location of your ball is below than 400 then the robot would stop, and if it is higher then the robot will continue to chase the ball and so on.
Hi, Sorry to message you after you've done this video 1year 3 months later but is it possible for Samsung S6/S7 to work, if no then how about Samsung A5??
Hi, yes it can. You will need to use the correct OpenCV Manager version for your phone. Try to download the OpenCV Manager that suits your phone here: goo.gl/8hWrhL (Version 2.4) or here goo.gl/Ph7po4 (Version 3.1). Try the Version 2.4 first. For example for my Huawei P20 Lite that uses Android Oreo 8.0.0, the version that fits the phone is OpenCV_2.4.11_Manager_2.20_armv7a-neon-android8.apk. Hope this helps. Thanks!
Sorry but just asking, when I use the L298N motor driver and the code, the motor doesn't move, and external power I give it is 12Vdc for 2 12Vdc powered motor. But when I check the reading for the Vdc, it's 12V from the power supply and 300+mV for the place where I connect the motor, any idea how can I fix this?
Yes, however your Arduino board needs to be connected to the PC during the read process. So at that time the robot cannot move far away as it is tied by the USB cable. To be more convenient, just use the Serial Monitor which is already integrated with the app.
but when i see the serial monitor there is no data comming . i already set the color that i track and press the start button on the app .. but still no data about the tracking on the serial monitor where is te serial monitor in the app?
Hey nude, saya sdng mencoba membangun robot seperti ini, tetapi mengapa ada problem disaat aplikasi robosot omnivision di running muncul error', mungkin ada solusi? TRIms sblmnya
hi it is very nice project i am facing issue with Color Tracking App some time menu not come can you please share tutorial video of apps use and different function of app also i am use lenovo k4 mobile and some time get error of open CV i have to uninstall and install then only its work can you please share which open CV those you use this project. how to stop bot with specific distance can you share remote app link thous you use in this video
Hi, to access the menu you need to press once on the blue "MENU" button, then tap anywhere on the screen, preferably on empty area. I used OpenCV4Android sample which I have heavily modified to come out with this app. To stop the robot, you may use "Normal" mode which the button is located below the red "STOP" button and right to the "Always+" button on Page 2 . This will make the robot react to the origin of x and y axis that appears on the screen. Try to lower the position of horizontal or x-axis by pressing the "Center_horz" button (press on "-" symbol to make it going down). When the tracked object is on the middle interception point between x and y axis it will stop and if it is below than the x-axis the robot will start to go backward.
Thanks for quick reply! i will check and take help if need after followed you provide steps can you please share link of open CV please. Also tutorial of this app because i see there lot of function will be done in single app it is very Geate app. Soccer, Avoidance, Localization, Passing. can you please share?? Please!!
Actually this app was developed for FIRA competition under Robosot category which consists of Soccer, Avoidance, Localization and Passing challenge. You may get more info about the competition on www.fira.net website and more of this app in actions here: ruclips.net/video/3o3mJYype7E/видео.html, here: ruclips.net/video/OXmWRIoyrPU/видео.html and here: ruclips.net/video/YnIY-CSk67o/видео.html. In fact this app was used in the last robot tournament in Beijing which was held on 13-19 Dec 2016 and managed to get some good places there. If I have time I will update you the tutorial deeper on using this app but for the time being, please enjoy building the vision controlled 4WD Arduino robot first :)
Hello encik nudge me,saya senang banget dengan projects yg anda buat,dan 1 Minggu terakhir ini saya coba buat robot model 4 WD colour tracking sprti projects yg anda buat,komponen nya semua sama persis saya gunakan seperti komponen robot anda di video di atas,tapi semua tidak berjalan bagus, robot saya tidak bisa bergerak lincah seperti robot anda,robot saya hanya bisa tracking objek ketika saya taruh di depan objek,ketika objek saya gerakkan atau ambil,robot saya tidak bisa mencari objek tersebut,robot saya tidak bisa bergerak ke kanan atau ke kiri mencari objek tersebut,apakah ada setingan kusus di aplikasi handponnya yg harus saya seting agar robot saya bisa searching objeknya,saya hampir putus asa karena sudah berkali kali coba perbaiki tapi tidak berhasil,please tolong saya agar robot saya bisa seperti robot anda,terima kasih....
+Made Wira Coba anda naikkan nilai pref_speed dengan menekan butang + dan apabila nilainya meningkat dan robot mula bergerak, tekan sahaja sekali di tengah skrin untuk menghentikan peningkatan nilainya itu. Pref_speed bermaksud 'prefered speed' yang membolehkan kita menetapkan kelajuan yang diingini untuk robot kita (bertindak sebagai pekali atau coefficient). Jika cara itu berhasil, makanya anda boleh terus setia dengan cara itu atau jika anda suka, anda boleh membuat sedikit perubahan pada Arduino code yang saya akan jelaskan kemudian nanti.
Terima kasih atas sarannya saya udah coba tadi naikan pref speed malah sampai 140 tp tetap tidak berfungsi,robot hanya bisa melaju lebih cepat,tp tetap tidak bisa search objek ketika objek tidak di depan robot,tolong bantu saya cara merubah codingnya(programnya)karena saya agak kurang paham bahasa pemrograman,terima kasih encik nudge me...
+Made Wira Untuk tujuan pusingkan robot, anda perlu naikkan nilai Rot. Speed pula. Tekan butang + sehingga nilai Rot. Speed itu meningkat. Rot. Speed ialah "rotational speed" bermaksud kelajuan pusingan.
Hello, what's your problem? I have just now tried to install the app into my OPPO F9 Pro and it works like charm. What I did was I installed the v4.6 app from goo.gl/VH2r8G and 'OpenCV_3.1.0_Manager_3.10_armeabi-v7a' from goo.gl/Ph7po4 into the phone. Please note that not all phone uses same OpenCV Manager file, you need to try install it one by one until the installation is successful.
When i download the color tracking app it doesnt work, and why do we ned the open CV Manager, and when i open it it says check for update and thats it. Pls help
Hi, try to download the OpenCV Manager that suits your phone here: goo.gl/8hWrhL (Version 2.4) or here goo.gl/Ph7po4 (Version 3.1). Try the Version 2.4 first. For example for my Huawei P20 Lite that uses Android Oreo 8.0.0, the version that fits the phone is OpenCV_2.4.11_Manager_2.20_armv7a-neon-android8.apk. The reason it needs the OpenCV Manager is because the app depends to the additional libraries that are provided by the OpenCV Manager to execute the image processing tasks.
hello! so we tried making this project but unfortunately only two dc motors responded. how to properly use the android app? I mean setting the app properly before using?
+Dale Gahisan Hi, make sure that you have selected the 2WD/4WD mode through the Menu for controlling 4WD kind of robot. This can be done by tapping on blue Menu button once and then tap the middle screen until a selection menu pops up. Then press more before selecting the 2WD/4WD option. You can view the selected mode by referring to the bottom of the screen either it says "2WD Out:" or "3WD Out:". The "(NC)" indicates that you have not yet connected the app to any Bluetooth device and when you have done the connection, the "(NC)" will disappear.
the TX of BT module is connected on A2 of arduino like in schematic. if I click start on my mobile phone the geared motor starts producing a buzz like sound
Yes, but you can direct it to detect any color you want. Just tap on the screen what color you prefer and the app will keep tracking the color afterwards.
Pair the HC06 module first with your phone using the phone's settings. Then launch the app, tap on blue BT button twice, then click Search then select the HC06 module from the list.
Kalau anda gunakan phone model terkini, elakkan daripada menggunakan full screen mode. Nanti buttons akan beralih dari tempat asalnya. Untuk menggunakan button-button pada app juga, sila tekan 2 kali pada setiap button sekiranya sekali tekan tidak berjaya.
HI I am trying to run the Android app, and I keep on getting an OpenCV initialization error, is there a fix for that? (I loaded the latest OpenCV manager from google play). Please let me know. Thank you.
Nadim Fata Hi, what phone model do you use? This app may not work with all phones as it has the issue with OpenCV version. I use Samsung Note 2, 3 and 4 and it works just fine with the app.
+Nadim Fata I checked on the net it runs on Nougat OS and I believe that's the reason it won't work. For the time being I suggest you use older version phone to run this app and maybe in the future I will update the app to work with higher version of phones. Sorry for that.
Nudge Me Oh that’s too bad, I was going to use your demo and show it to a bunch of kids on Thursday. If you can help me out to get it working it would be great. I will try to get an older phone as well. Thanks.
Nadim Fata FYI, I have tried it once and it was not easy. I had to migrate to Android Studio and deal with new libraries and issues to do that, which involved so many new things. That would take lots of time and for now, I don't have that much time :(
Sir i need help when i install everything and then nothing of my screen buttion in app works whenevr i click on menu it didnt show me i am using mate 10 lite huwaie
For example the new phone that I am using now which is Oppo F9 also having the same problem as yours, believed to have incompatible resolution with the app.
Very easy. Follow these steps (if you want the app to control your robot car, make sure you connect the app to the Bluetooth first as if not, all the following steps will be reset and you will need to start over again): 1. On Page 1, click on BALL button. Then click on / symbol next to the BALL button. 2. Point the camera to the object colour (in this case green) you want to detect, then tap on that object's image. The app will highlight the object detected. 3. If you are satisfied with the detection coverage, click OK button. If not, adjust the detection quality by playing around 3 values in the red boxes located at the bottom left of the screen (the red boxes only appear after you click BALL button, and will be hidden when you click OK button). The green numbers inside the red boxes denote the values for HSV's range. You can also adjust the HSV values by pressing the Range button (located next to the yellow box beside the OK button), and when it turns to yellow, the HSV values will be shown. Normally, we don't really need to adjust the Range and HSV values as the app will automatically set the best values every time we tap on the object's colour we want to detect. 4. Press Lock AE (lock auto exposure) and Lock WB (lock white balance) to make sure those parameters are reserved even the surrounding lighting changes. 5. The label Comb. on the Comb. button will make the app combine all the same colours into one COG (center of gravity). If you want the app to detect the largest blob, press on it until it display Larg. Else if you want the app to detect your desired colour separately, click on it again until it display Sepa. 6. If everything is OK, press OK. If you want to edit the detection parameters again, just press on the BALL button again. 7. Go to Page 2, increase Rot. speed (rotational speed) and Pref. speed (preferred speed) as you wish and click START button to make your robot move. Press STOP button to make it stop.

Hi, the app was actually developed for robotic competition named FIRA (firaworldcup.org) under the Robosot category. It can be used to perform soccer playing, obstacle avoidance challenge (ruclips.net/video/3o3mJYype7E/видео.html), localization task (ruclips.net/video/OXmWRIoyrPU/видео.html) and passing routine. All of these things need a particular environment setting to run, such as field, obstacles, patches and so on. So for the time being, as all of those props are not around, it is a kind of difficult for me to demonstrate the advance use of the app. Hopefully, when the correct time comes, I would be able to do it and post the video to this channel :)
This is the best project ever! Brother! i want to ask about: Can Rot.speed adjust to exceed 250? Thanks very much. Looking forward to receiving feedback as soon as possible
Hello, exceeding 250 would be too much. However, if you still prefer to use the rotational speed value that much, you can map it in the Arduino code instead.

The Lipo battery is expensive which battery can I use otherwise

Is there a way to use RFID tags instead of colour?so that the robot can track the object with the RFID?
+amiskapinga Yes, but the robot needs to be mounted with RFID reader then. And keep in mind, the RFID works when both of the tag and reader are close in range, so the robot may need to go 'sniff' the tag to read it.

2. Point the camera to the object colour you want to detect, then tap on that object's image. The app will highlight the object detected.
3. If you are satisfied with the detection coverage, click OK button. If not, adjust the detection quality by playing around 3 values in the red boxes located at the bottom left of the screen (the red boxes only appear after you click BALL button, and will be hidden when you click OK button). The green numbers inside the red boxes denote the values for HSV's range. You can also adjust the HSV values themselves by pressing the Range button (located next to the yellow box beside the OK button), and when it turns to yellow, the HSV values will be shown. Normally, we don't really need to adjust the Range and HSV values as the app will automatically set the best values every time we tap on the object's colour we want to detect.
4. Press Lock AE (lock auto exposure) and Lock WB (lock white balance) to make sure those parameters are reserved even when the surrounding lighting changes.
5. The label Comb. on the Comb. button will make the app combine all the same colours into one COG (center of gravity). If you want the app detect the largest blob, press on it until it display Larg. Else if you want the app to detect your desired colour separately, click on it again until it display Sepa.
6. If everything is OK, press OK. If you want to edit the detection parameters again, just press on the BALL button again.
7. Go to Page 2, increase Rot. speed (rotational speed) and Pref. speed (preferred speed) as you wish and click START button to make your robot move. Press STOP button to make it stop.
After following all the steps above your robot still doesn't move? Or on which specific step you did face the problem?
@@nudgeme4844 Hi Mr Nudge Me, thank you very very much for responding to my queries. I will follow the steps that you have given and I will update you on my progress very soon. I am keeping my fingers crossed. Thank you sir
I cannot find the Bluetooth option in the app
I did all the connection and able to part the bluetooth , but the movement of the robot seem weird . later I post up my video. what a great project by you .
Hi, may I see the video?
i need to install all the opencv files that you mentioned ?
Definitely yes
Can you make a tutorial video about this project? Its aa request
Hi! Great work. I was wondering how the obstacle avoidance function worked and how would we implement it? Thanks!
Hi, you can refer to this video to see how it works: ruclips.net/video/3o3mJYype7E/видео.html. Thanks for your support.
Thanks for making open source.... I built this robot and it's basically working with some issues.... it can follow the red ball but it has to be very very slow or it looses the ball and hits another object.... in your opinion is this the phone or version of openCV manager... The Arduino code seems to work flawlessly. If you move the ball out of the cameras sight it can easy loose track unless you are at least 1.5M away and very slow... Thanks
Hi, the lag may be caused by the phone. FYI, not all high end phones can handle the image processing in a fast way. For example, Samsung Note 2 surprisingly can perform better than Samsung Note 4 and most of the Huawei, Oppo and Vivo phones. The algorithm should make the robot turns to the last sight of the ball before it loses track, for example it will turn left if it loses ball at the left of its sight. Thanks for your comment :)
I suspected the phone it's a cheap infocus phone that my wife said was crap and it is so I used it in this project... instead of using a ball I'll use something slower like a red target on my cat.. give the little cat some exercise..haha.. thanks for the reply... Do you have any new projects in the pipe line?
Also is it possible to integrate your object tracker car and bluetooth RC car into one sketch?
Yes, it is possible to do that. Just modify the string parsing part at
if (getData == '~') {
x = Serial.parseInt();
......
part.
Haha, hopefully your cat will cooperate. Yes I do, but it is still in R&D stage and probably when everything is done I will share in my channel soon.
is there any way for the robot to stop when reaching the distance with the ball?
You need to adjust the horizontal line level of the crosshair as when the center of the crosshair hits the ball's COG, the robot will stop.
Should I download all the file's of opencv 2.4 v?
hi plz in your code SoftwareSerial mySerial(A2,A3); // Connect the TXD pin of BT module to pin A2 of the Arduino (or the L293D motor shield). The RXD pin of BT module and A3 of Arduino can be left unconnected. YOU connect tx to A2 and RX to A3
Hi projects are very good and thank you for these projects.
I did this project with my son, but opencv manager does not work on my phone samsung s6 + edge.

hey there nice work am using l298n motor driver and the code is not working are u sure that code can match both the joystick and the color tracking app
Yes, it should work on both joystick and color tracking app. make sure you select the correct mode on the joystick app through the menu, which is 2wd/4wd mode.
Hi Nudge Me!
Your projects are awesome! Thank you so much for doing these and sharing them. We are using your project to help teach kids about Arduinos, robotics, and programming and they love it! You should be proud.
I noticed there is an issue with trying to use the Color Chasing App on the Omni 3 Wheel versions. I believe it is linked to there being no ".'" case statement in the code to handle the "w" variable.
Have you addressed this anywhere?
I can share my revisions to your code if it will help, but I'm not certain I have modified it exactly correctly.
Either way, all the kids, the professor, and myself are a huge fan of your work. I just wanted you to know that!
hello brother! i am having when the car can't stop when it catches the ball. Please help me !!!
Can you provide the source code of android app. and there is no brief instruction to handle your app. i mean to use it
maaf saya ingin bertanya, pada program arduinonya, variabel stateA0, stateA1, dan state11 dihubungkan kemana ya?
You have not done connection in RXD of the Bluetooth module.
You can connect RXD or not
We need to connect rxd or not?

Why application is not working
Hello sir, you have a wonderful project. I want to build one, but I have a request for the code in Rabat. They ask me to send you a message so that I can solve it, but you did not respond, and that is why I could not build it. Help me, please.
hi, thanks for this great project. i have tried alot and made this project with some of issue resolved but some left unresolved like i have increase the battery to 12v and 1amp, which power up and make car movable but the problem is that when ball move left or wright the car get it hard to rotate and sometimes it rotate and sometimes not
Hey, you need to set up the parameters that fit your robot. Goto Page 2 on the app, increase rotational speed by pressing + sign on the Rot. speed section. To make your robot go faster, try increase the Pref. speed value. Hope this helps. Thanks!
@@nudgeme4844 sir when the ball goes to left side then the car turns to left side & rotates correctly but when it comes to right side the car goes reverse side or car does not turn & get stopped.... And another thing in your video when you move your ball behind the car it fully rotates or take U-turn itself but when i move my red ball the car get stopped and doesn't move.... give reply as soon as possible i have to submit it...
Maybe your case is same with Malik's one. Goto Page 2 on the app, increase rotational speed by pressing + sign on the Rot. speed section. Press the + sign after you start your robot. Let the value increase until the robot turn successfully and stop the increment by pressing anywhere on the center of the screen. Hope this helps.
Hi man! I've done the same project as in your video. But the robot does not move though the app works well. I used a pin lipo 7.6v 3.8a power supply for arduino uno and 4 DC motors. Help me !!!
Hello! Try to check the connection to the Bluetooth module, RXD and TXD pin of BT module needs to go to the correct pins on the Arduino and the grounding of motor driver module and the Arduino should be common (connected together).
Thank you man!
It worked but I have to choose xy mode, not 2wd / 4wd mode as in your tutorial. Can you explain me?
xy mode is actually sending the x and y coordinates of the tracking object to the Arduino while the 2WD/4WD will send the processed wheel speed values based on the location of the object. Maybe you used the Arduino code that processes the first option, not the second one.
How are these mode suitable for control purposes?
It depends on what do you want the robot to do. If you want the output to be directly in the form of processed wheel speeds, then opt for the 2WD/4WD mode. But anything that is more than that such as decision making and etc would be beyond your control. On the other hand, if you choose the x and y output mode, you can do further decision making on your Arduino such as if the y location of your ball is below than 400 then the robot would stop, and if it is higher then the robot will continue to chase the ball and so on.
At the time. Of connecting the application with the bluetooth module hc-6 help please😔😔
can you make the documentation on how to use the android app?
Arduino code isnot work....pls give another code....or define file for serial communication....
Hi, Sorry to message you after you've done this video 1year 3 months later but is it possible for Samsung S6/S7 to work, if no then how about Samsung A5??
Hi, yes it can. You will need to use the correct OpenCV Manager version for your phone. Try to download the OpenCV Manager that suits your phone here: goo.gl/8hWrhL (Version 2.4) or here goo.gl/Ph7po4 (Version 3.1). Try the Version 2.4 first. For example for my Huawei P20 Lite that uses Android Oreo 8.0.0, the version that fits the phone is OpenCV_2.4.11_Manager_2.20_armv7a-neon-android8.apk. Hope this helps. Thanks!
Sorry but just asking, when I use the L298N motor driver and the code, the motor doesn't move, and external power I give it is 12Vdc for 2 12Vdc powered motor. But when I check the reading for the Vdc, it's 12V from the power supply and 300+mV for the place where I connect the motor, any idea how can I fix this?
can i read the data from the android apps on the serial monitor arduino?
Yes, however your Arduino board needs to be connected to the PC during the read process. So at that time the robot cannot move far away as it is tied by the USB cable. To be more convenient, just use the Serial Monitor which is already integrated with the app.
but when i see the serial monitor there is no data comming . i already set the color that i track and press the start button on the app .. but still no data about the tracking on the serial monitor
where is te serial monitor in the app?
It is possible to do it with the shield L298P (DEEK-ROBOT).
SHIELD MODEL MOTOR R3.
THANK YOU
As long as it is an Arduino-based board and a suitable motor driver, it should work without any problem.
Hey nude, saya sdng mencoba membangun robot seperti ini, tetapi mengapa ada problem disaat aplikasi robosot omnivision di running muncul error', mungkin ada solusi? TRIms sblmnya
hello! the app is not responding to the motors what should i do

hi it is very nice project i am facing issue with Color Tracking App some time menu not come can you please share tutorial video of apps use and different function of app also i am use lenovo k4 mobile and some time get error of open CV i have to uninstall and install then only its work can you please share which open CV those you use this project. how to stop bot with specific distance can you share remote app link thous you use in this video
Hi, to access the menu you need to press once on the blue "MENU" button, then tap anywhere on the screen, preferably on empty area. I used OpenCV4Android sample which I have heavily modified to come out with this app. To stop the robot, you may use "Normal" mode which the button is located below the red "STOP" button and right to the "Always+" button on Page 2 . This will make the robot react to the origin of x and y axis that appears on the screen. Try to lower the position of horizontal or x-axis by pressing the "Center_horz" button (press on "-" symbol to make it going down). When the tracked object is on the middle interception point between x and y axis it will stop and if it is below than the x-axis the robot will start to go backward.
Thanks for quick reply! i will check and take help if need after followed you provide steps can you please share link of open CV please. Also tutorial of this app because i see there lot of function will be done in single app it is very Geate app. Soccer, Avoidance, Localization, Passing. can you please share?? Please!!
Actually this app was developed for FIRA competition under Robosot category which consists of Soccer, Avoidance, Localization and Passing challenge. You may get more info about the competition on www.fira.net website and more of this app in actions here: ruclips.net/video/3o3mJYype7E/видео.html, here: ruclips.net/video/OXmWRIoyrPU/видео.html and here: ruclips.net/video/YnIY-CSk67o/видео.html. In fact this app was used in the last robot tournament in Beijing which was held on 13-19 Dec 2016 and managed to get some good places there. If I have time I will update you the tutorial deeper on using this app but for the time being, please enjoy building the vision controlled 4WD Arduino robot first :)

Hello encik nudge me,saya senang banget dengan projects yg anda buat,dan 1 Minggu terakhir ini saya coba buat robot model 4 WD colour tracking sprti projects yg anda buat,komponen nya semua sama persis saya gunakan seperti komponen robot anda di video di atas,tapi semua tidak berjalan bagus, robot saya tidak bisa bergerak lincah seperti robot anda,robot saya hanya bisa tracking objek ketika saya taruh di depan objek,ketika objek saya gerakkan atau ambil,robot saya tidak bisa mencari objek tersebut,robot saya tidak bisa bergerak ke kanan atau ke kiri mencari objek tersebut,apakah ada setingan kusus di aplikasi handponnya yg harus saya seting agar robot saya bisa searching objeknya,saya hampir putus asa karena sudah berkali kali coba perbaiki tapi tidak berhasil,please tolong saya agar robot saya bisa seperti robot anda,terima kasih....
+Made Wira Coba anda naikkan nilai pref_speed dengan menekan butang + dan apabila nilainya meningkat dan robot mula bergerak, tekan sahaja sekali di tengah skrin untuk menghentikan peningkatan nilainya itu. Pref_speed bermaksud 'prefered speed' yang membolehkan kita menetapkan kelajuan yang diingini untuk robot kita (bertindak sebagai pekali atau coefficient).
Jika cara itu berhasil, makanya anda boleh terus setia dengan cara itu atau jika anda suka, anda boleh membuat sedikit perubahan pada Arduino code yang saya akan jelaskan kemudian nanti.
Terima kasih atas sarannya saya udah coba tadi naikan pref speed malah sampai 140 tp tetap tidak berfungsi,robot hanya bisa melaju lebih cepat,tp tetap tidak bisa search objek ketika objek tidak di depan robot,tolong bantu saya cara merubah codingnya(programnya)karena saya agak kurang paham bahasa pemrograman,terima kasih encik nudge me...
+Made Wira Untuk tujuan pusingkan robot, anda perlu naikkan nilai Rot. Speed pula. Tekan butang + sehingga nilai Rot. Speed itu meningkat. Rot. Speed ialah "rotational speed" bermaksud kelajuan pusingan.
hi sir your project is very interested.I have a problem to install application in my OPPO A57 android version 6.thanks to help me...

Please note that not all phone uses same OpenCV Manager file, you need to try install it one by one until the installation is successful.
When i download the color tracking app it doesnt work, and why do we ned the open CV Manager, and when i open it it says check for update and thats it. Pls help
Hi, try to download the OpenCV Manager that suits your phone here: goo.gl/8hWrhL (Version 2.4) or here goo.gl/Ph7po4 (Version 3.1). Try the Version 2.4 first. For example for my Huawei P20 Lite that uses Android Oreo 8.0.0, the version that fits the phone is OpenCV_2.4.11_Manager_2.20_armv7a-neon-android8.apk.
The reason it needs the OpenCV Manager is because the app depends to the additional libraries that are provided by the OpenCV Manager to execute the image processing tasks.

hello! so we tried making this project but unfortunately only two dc motors responded. how to properly use the android app? I mean setting the app properly before using?
+Dale Gahisan Hi, make sure that you have selected the 2WD/4WD mode through the Menu for controlling 4WD kind of robot. This can be done by tapping on blue Menu button once and then tap the middle screen until a selection menu pops up. Then press more before selecting the 2WD/4WD option. You can view the selected mode by referring to the bottom of the screen either it says "2WD Out:" or "3WD Out:". The "(NC)" indicates that you have not yet connected the app to any Bluetooth device and when you have done the connection, the "(NC)" will disappear.
thanks for the response +Nudge Me. is impossible to combine this program to manual bluetooth controller?
our device has a beeping sound everytime we connect it to our android device is that normal?
Dale Gahisan Hi, you can control this robot car manually using joystick app as shown in this video: ruclips.net/video/MBs023AoHQk/видео.html.
Dale Gahisan What kind of Bluetooth module do you use?
Why my robot didn't moving? please help me. thank you!
Maybe the TX pin of Bluetooth module is not connected to RX of Arduino and vice versa?
the TX of BT module is connected on A2 of arduino like in schematic. if I click start on my mobile phone the geared motor starts producing a buzz like sound
but still it's not moving.

Nadim Fata Hi, what phone model do you use? This app may not work with all phones as it has the issue with OpenCV version. I use Samsung Note 2, 3 and 4 and it works just fine with the app.
Nudge Me thanks for your reply, I am using Redmi 5A Qualcomm snapdragon 425
+Nadim Fata I checked on the net it runs on Nougat OS and I believe that's the reason it won't work. For the time being I suggest you use older version phone to run this app and maybe in the future I will update the app to work with higher version of phones. Sorry for that.

Can you give the extra video for use of app
Hi, the app was actually developed for robotic competition named FIRA (firaworldcup.org) under the Robosot category. It can be used to perform soccer playing, obstacle avoidance challenge (ruclips.net/video/3o3mJYype7E/видео.html), localization task (ruclips.net/video/OXmWRIoyrPU/видео.html) and passing routine. All of these things need a particular environment setting to run, such as field, obstacles, patches and so on.
So for the time being, as all of those props are not around, it is a kind of difficult for me to demonstrate the advance use of the app. Hopefully, when the correct time comes, I would be able to do it and post the video to this channel :)
This is the best project ever!
Brother! i want to ask about: Can Rot.speed adjust to exceed 250?
Thanks very much. Looking forward to receiving feedback as soon as possible
Hello, exceeding 250 would be too much. However, if you still prefer to use the rotational speed value that much, you can map it in the Arduino code instead.
