Thanks to the help of several of you, I managed to get my activity bot to be both RC controlled as well as autonomously search and avoid obstacles. It's pretty awesome.
I was wondering though, is there a way for the propeller board to power four wheels? I see a lot of 4wd RC smart car kits out there, but they seem to all be for arduino.
Are there any 4-motor motor shields for propeller? How do I use the propeller language to program these?
Basically, I just wanted to convert my current robot program into a larger, more rugged off road type vehicle. Is this possible?
