You're really good a mechanically drafting. I mess around in Blender 3D, but you're doing some next level stuff in Fusion 360. This is probably the best Robot Arm I've seen on RUclips that's homemade. Definitely better crafted and designed than those DFRobot Robot Arm Kits.

Ciao, complimenti per il progetto, mi ha affascinato da subito, sto terminando la stampa di tutti i pezzi, solo che trovo una grande difficoltà nel reperire tutte le cinghie, pulegge e cuscinetti necessari. Non sarebbe una cattiva idea se mettessi a disposizione un kit pronto per l'acquisto di tutte le parti meccaniche. O magari dei link diretti per l'acquisto....spero tu possa aiutarmi, complimenti ancora, Sabino.
Thank you! Very good question! I don't have any sensors for homing. For the moment the Arduino program knows exact initial coordinates, and like this it works without homing. But I use Trinamic drivers, and with them I can home all motors without limit switches (like it is done on the Prusa i3 MK3 printer), but I didn't implement this feature yet.
What sheet are you using on your printer to print PETG? It looks like the Spring steel smooth one but I heard it can damage the bed material. How did you do this? Thanks for great content 👍
Yes, it is smooth PEI. I apply a glue stick on it (I use standard glue stick, which is provided with prusa printer). The glue helps to release the part. (Usually we apply glue for better adhesion, but here the glue works like separation) It works perfectly and I have not damaged any steel sheet. Usually I apply a little bit of glue on the sheet in the middle and after I use paper towel with alcohol to smudge the glue homogeneously. You need a tiny tiny layer of the glue. Usually this glue layer last for 2-4 prints, and after I reapply it.
@@Skyentific Thanks for your reply Sir. I ended up using the textured sheet in the end. Finished printing all the parts, got most of the mechanical components too, assembling now!
Wonderful work. This is one of the best DIY Robots related channel in RUclips. I see you're using Prusa i3 MK3S 3D printer. Do you recommend going for Prusa Mini (print area 18x18x18cm) as its much cheaper?
Здравствуйте! Столкнулся с такой проблемой - распечатанные детали не сопрягаются между собой (( не подходят на десятые доли миллиметра, постобработку выполнять очень сложно и неаккуратно получается. В чем может быть причина? Или нужно сопряжения сначала промазывать клеем для размягчения пластика?
Скорее всего ваш принтер не совсем точно печатает. Я отдельно калибровал свой принтер. И с хорошей калибровкой, единственное что я делал - откавыривал поддержку.

@Skyentific nice small arm anyway without to be mounted on a moving chassis it will loose both precision and working space from what it should be with it :) i hope that you will make more solid arms with it so you could sell some of your good things produced by your arms
Very nice and inspiring work. Tried to apply your arduino code to my 5 DOF arm, but bid not work correctly. Maybe because of the DH matrix or youe equations. If you can help, it would be appreciated. Also pls explain the positions nominations and code if possible. Thanks
I plan to do the next video about the software and also explain the kinematics of this robot. I can also try to help you, if you would give me more details about your robot and what do you mean by did not work correctly?
@@Skyentific hi. 1) my robot is 5 dof. Meaning i dont have your joint #4. So i am not sure how the DH matrix theta and alpha (lines 595 and 596) should look like. 2)my robot geometry is as follows R1=0 R2=200 R3=150 D1=200 D3=0 D4=0 D6=135 3) i need to know what are the 6 parameters in the X positions (lines207 to 211). Are they end effectir X,Y,Z in millimeters and rotation around X6 and Y6 and Z6? In degrees? I will be waiting your video about the code. It will certainly help alot. I have already used your part of the code for stepper driving. The acceleration and decelleration phases are great and help alot in torque management when the steppers starts and ensure a smooth arriving to target. I love it. I was using accelstepper lib but it cant do this in multi stepper mode.
Hi Skyentific, thanks for sharing all this with us. May I ask, how many roll of filament did you use for printing your robot arm? Can share where you got the yellow color from? Thank you.
Hi, I am a electronics enthusiast and I was wondering if you sell your robot arms. I would love to build one but I have ALS and my body is not working... I want to program one to feed me.
Heya; when you use those 3d printed pulleys do you model them yourself/use generators or do you get them from manufacturers who provide CAD models for their products?
Hi, great work on the robot! I am wondering how u managed to control the motors? As far as I know, it is impossible to know the position of stepper motors without some kind of an encoder or end stop switch, which u seem to have used none of such. I'm building a robot arm myself and your advice would help me in a lot of ways! Thanks!
you just put the robot into a known position first either manually or automatic with homing switches and after that you can just count the steps of the motors and there is your position
Hello pal. I assume that you made the drawings in Fusion. Could you add .ipt or step files of the assembly and parts. Stl files not usable for autodesk inventor. I would like to increase the geometry if you may upload .step or .ipt
You can learn robotics, electronics, math for inverse kinematics, and physics. But I think the best way is to start to build something, and as soon as you have problem, learn something to solve it. Like this it is more fun. I only learned math and Physics at university, robotics and electronics I learned on the go, when I needed it.
Hi! I've watched all your videos on the 6DoF robot arm and they way you explain everything motivated me to order the parts to build one myself (for school). Unfortunately, I've hit a roadblock with the bearings from Engrenages HPC. They only ship orders of 500E, but the bearings required sum up to 40E, so they cant provide with the bearings. Do you have an alternative for the bearings from another supplier? Thank you very much! :)
@@Skyentific Hello! So far, i've found an alternative for the bearing on aliexpress, the only one that's left for me to find is the 21x15x4mm. I've found the 6702ZZ, but the specs are 15x21x4mm (the numbers are not in the same order). But based on the video, i think it might be the right model. Is that correct? Also, regarding the Swagelok tubes, would it be possible to use an alternative other than steel? Like plastic or brass?
Hello! Excellent question. Yes, I will make electronics and soft open source. The electronics is quite simple. The soft is written in Arduino. I never worked with ROS, but I think in the future I will try to implement it in ROS (and I have no idea how difficult is it). :)
Hello dude the project is masterpiece. Accurate and good repeatibility. I would like to open and modify the your drawing and play with it. Could you upload step or ipt files to github, I can not use stl files I would be very glad.Meshed drawing has no surfaces.Otherwise we have to 3d print the files one by one and make measurement on each part 😃

hi firiends ı like your projeckt ı am from turkey and ı have channel to youtube in turkish can ı coppy and can ı do it video to your projeckt. ofcores ı give to link your chanel and your web
I would like to buy your latest completed robot arm, what is the price, how to buy and what is the payload, I need a good end effector for pick and place of 1 to 2 kg objects. I searched in many places how to contact you and I could not find a contact email address. This is very impressive you should scale up to manufacturing, I am sure you will sell a lot. Please reply how we can buy? Thanks
Totally enjoyed the video. Thanks for the amazing work. I have two questions: 1. Is it better to use stepper motors or servo motors to make a robot arm like yours? 2. Can you also include a one-time donation scheme instead of the monthly option?
Very good questions! Thank you for comment. 1. With the professional industrial servos it is possible to make an excellent robot arm. But these servos cost from maybe 500 dollars. But cheap servos, which people usually use, have very low precision thus the robot arm has a precision of only 5mm (or some times even 10mm). With stepper motors it is more difficult to make robot arm (as you would need to make some kind of gearbox (reducer)). But with steppers you could get a 0.1mm precision. And also with stepper motor you can control the acceleration (you cannot do this with cheap servos), thus with steppers the robot arm moves more smoothly. 2. Good advice! Thank you. I will do this!
@@Skyentific thanks for this very good answer to understand this from the ground! May i ask because i havent found the answer so far, how much gramm or kg will it be able to work with? And how much precision your build - the has atm?
Hello this question is translated from turkish to english: I printed the robotic arm and equipped it with Ramps 1.4 and TB6600 and TMC 2209 drivers. I also created an APK via MiT_Inventor, everything works perfectly! Now to my question: How can I combine 2 sketches into one via Arduino, i.e. practically the normal Sketch.ino without Bluetooth and the Sketch with Bluetooth.ino.... so that I can freely choose which one I start? The 2nd question would be whether I can then integrate it into my APK file? I would be very happy if you help me in this regard, or you make a new RUclips video on how to add it further. I have mastered the basics of programming: You can see my robotic arm here on RUclips: ruclips.net/video/MF7dO4dAIAw/видео.html

I've found the 6702ZZ, but the specs are 15x21x4mm (the numbers are not in the same order). But based on the video, i think it might be the right model. Is that correct? Also, regarding the Swagelok tubes, would it be possible to use an alternative other than steel? Like plastic or brass?
This is the same bearing. For the tube: the brass would be ok, if it has right dimensions. The plastic, I am afraid, would not be strong enough.
I know that sweglok tubes can be difficult to find, usually they sell them by 5m long tubes :).
please i want the sld file of this robot
whats the max payload capacity of this arm
Очень круто!! А планируеться открывать електронику и софт?
Так же интересует будет ли интеграция с ROS??
Hello! Excellent question. Yes, I will make electronics and soft open source. The electronics is quite simple. The soft is written in Arduino. I never worked with ROS, but I think in the future I will try to implement it in ROS (and I have no idea how difficult is it). :)
How much does it cost to build this robotic arm?
Hello dude the project is masterpiece. Accurate and good repeatibility.
I would like to open and modify the your drawing and play with it.
Could you upload step or ipt files to github, I can not use stl files I would be very glad.Meshed drawing has no surfaces.Otherwise we have to 3d print the files one by one and make measurement on each part 😃
hi firiends ı like your projeckt ı am from turkey and ı have channel to youtube in turkish can ı coppy and can ı do it video to your projeckt. ofcores ı give to link your chanel and your web
It can use g code?
Are the parts PLA or ABS?
Good joob!
Thank you. This is PETG. More precisely: prusament printed on Prusa. :)
@@Skyentific how much time did it take to print and how much plastic?
may I ask what your profession is?
Of course. I am scientist in plasma physics, nothing to do with robots. :)
@@Skyentific Have you ever used robots in your job (in plasma lab). And Sir, good job on whole series.
I would like to buy your latest completed robot arm, what is the price, how to buy and what is the payload, I need a good end effector for pick and place of 1 to 2 kg objects. I searched in many places how to contact you and I could not find a contact email address. This is very impressive you should scale up to manufacturing, I am sure you will sell a lot. Please reply how we can buy? Thanks
Excellent video. Is this robot accurate enough to hold a 3D printer extruder ?
Excellent question. I think it is accurate enough. I estimated the repeatability of this robot around 0.1mm.
Totally enjoyed the video. Thanks for the amazing work.
I have two questions:
1. Is it better to use stepper motors or servo motors to make a robot arm like yours?
2. Can you also include a one-time donation scheme instead of the monthly option?
Very good questions! Thank you for comment.
1. With the professional industrial servos it is possible to make an excellent robot arm. But these servos cost from maybe 500 dollars. But cheap servos, which people usually use, have very low precision thus the robot arm has a precision of only 5mm (or some times even 10mm). With stepper motors it is more difficult to make robot arm (as you would need to make some kind of gearbox (reducer)). But with steppers you could get a 0.1mm precision. And also with stepper motor you can control the acceleration (you cannot do this with cheap servos), thus with steppers the robot arm moves more smoothly.
2. Good advice! Thank you. I will do this!
@@Skyentific thanks for this very good answer to understand this from the ground! May i ask because i havent found the answer so far, how much gramm or kg will it be able to work with? And how much precision your build - the has atm?
...долго подбирал фразы с чего начать, но ничего впечатляющего...в общем: очень...очень-очень Нужны ваши видео на русском!
why not this robot have no Limit switch
Why it should have limit switches? It works perfectly fine without them :)
How to connect and control the robot with ROBODK? I've built the robot, but I can't program it.

Hello this question is translated from turkish to english:
I printed the robotic arm and equipped it with Ramps 1.4 and TB6600 and TMC 2209 drivers. I also created an APK via MiT_Inventor, everything works perfectly! Now to my question: How can I combine 2 sketches into one via Arduino, i.e. practically the normal Sketch.ino without Bluetooth and the Sketch with Bluetooth.ino.... so that I can freely choose which one I start? The 2nd question would be whether I can then integrate it into my APK file?
I would be very happy if you help me in this regard, or you make a new RUclips video on how to add it further. I have mastered the basics of programming: You can see my robotic arm here on RUclips:
