How to Build a GPS Guided Bluetooth Robot - Part 2
You can Download the Cellphone App from MIT App Inventor here
ai2.appinventor.mit.edu/?local...
or you can search for it in the Gallery under "GPS Guided Robot"
The Arduino code can be downloaded from Github Here
github.com/mkconer/GPSRobot
You will also need to download and install several libraries referred to in the code and the Videos and Instructable
This builds upon a Bluetooth Robot that I made in a previous RUclips Video
You can find the Instructable for it here.

Hi EZtech.
Thanks you for indicating via instructables;
Maybe my question is silly (I'm not programma code, or architect software) but hopeful you reply me. I have been reading overview "I started noticing that some people were building robotic lawnmowers, which seemed pretty simple. They were using RC remotes to control their lawnmowers, but there was one huge problem with this design. When the person would start out mowing the grass everything was great, but when they would reach the end of the lawn and turn around the person invariable got off course and would constantly have to correct their steering. Eventually, after getting off course so much they would give up trying to keep nice straight lines and just zoom all over the yard, which didn’t look very good. I also noticed that many of the commercial robotic lawn mowers operated on the same principle, zoom all over the yard in hopes that eventually all the grass would get mowed. This seemed very inefficient. I thought there had to be a better way"
And I'm thinking about concern diagram and pwm pinout (enable pins). Because if you upgrade big machine then you will use pwm pins function. So then this code will be changed.
Thank you ! Great video and great tips ! When would part 3 be up ?
Daisy Fernández This weekend, thanks for watching!
I just uploaded the Instructable on how to build the GPS Guided robot, check it out. www.instructables.com/id/How-to-Build-a-GPS-Guided-Robot/
@@EZtech @EZtech I need your help. I have done everything step by step. I have made the circuit, and calibrated the compass, and uploaded the code. And did everything which you told in this video. But the problem is that, I never got any output whenever I press any button in the app. Even the connection is proper and code is properly uploaded, also compass has been calibrated perfectly but nothing works with the app, whenever I press any button.
Can u make it only GPS without compass?
how can I contact to you? I doing that in my final process and i hope you will help me. thank you so much

Bro do you got the solution please update me if you solved the issue and if you did please tell how
Did you connect the VCC of the GPS into the 3v pin ? The RX works with 3V ?
Daisy Fernández The Ublox 6m GPS module is powered with 5 volts, as well as the HC-06 Bluetooth and the HMC5883l. I believe all of these can be powered by either 3 volts or 5 volts. I have had problems when powering the Bluetooth module with 3volts. There has been some discussion on the internet as wether or not the data lines, rx and tx should have a logic level shifter. I have only done that on the first robot I built, and had constant problems. Since I started powering everything with 5 volts all those problems went away.
EZtech Thank you !!
Daisy Fernández Did you take it outside? Depending on your location it may be difficult for the GPS module to lock on. Take it outside for 10 minutes with power hooked up, just vcc and ground is all you need. The LED should start blinking after it starts receiving nema sentences.
EZtech yes i did it, but it didn't work out.
Daisy Fernández I had one that I thought was dead, I left it hooked up near a window and was surprised when I came back hours later and it was working. You may also want to use a voltage meter and check to see if you have 5volts at the GPS. Also check for bad solder joints as well. If this all checks good then I would have to say the GPS module is bad.
Nice!
Sir, Should I use L298N module and 12v battery instead of L293d and 7.4v battery
I wouldn't suggest it, it would complicate the project. It could be done but be prepared to change alot of wiring

Has anyone encountered this issue? when I press the gps info button it shows me that my location is 5000+ km away from the robot. Any solution?
Brother do you got any solution for your problem please tell me the solution
@@n1troplayz268 yea, I fix it
