If I had another two weeks, I could do this. As is...
I am working on control by GPS course only. I just couldn't get the compass to work. It worked perfectly in the basement when the main wheels were held off the ground, but failed utterly at the park.
GPS has its own flaws, but I am down to my last option. I had to have my friend talk me out of giving up. It may not matter soon anyway.
Once I get control by GPS working, then I need guidance by GPS waypoint and bluetooth. Fortunately I have had a bluetooth attached to this before, all I need is a control protocol based on NMEA, an interpreter in the robot, and a sender in a laptop.
