It can work but you will see significant drift, in order to correct for drift you are going to need speed measurements. The link I posted is for drones so the GPS can provide X,Y and Z location (and therefore speed) measurements. You could get simmilar results with encoders on free rolling wheels on the robot in both the x and y direction (to do it right you would also need a magnetometer to establish direction but for the length of autonomous period you could get accurate enough results without it).
There's the problem!! The #1 reason to blame the programmers: They always forget to grease their code. :rolleyes: - Jack Jones [more]
