I want to make a radio-controlled car with the possibility of autonomous movement through GPS on a given track. There is some route outside. I plan to do it on Rasberi PI together with Pikhavk. I don’t understand how to implement it yet, maybe someone has similar articles / projects?
That is a broad question, but basically you want to do what ArduRover is all about. You shouldn’t need a Raspberry Pi at all, just a flight controller, such as a Pixhawk.
