Re: Non-FRC Bot
 

Would the range of the wireless control system affect your decision? Will it operate autonomously some of the time?

I think you'd probably be happiest with a skid steer robot....much easier to get out of sticky spots. And since you are not sitting in the vehicle when you're driving it, you will probably get into more sticky spots than you expect

Ideally it would be autonomous with manual backup.

I've got an idea. If the go-kart chassis is anything like I think it is, tear the current drivetrain off of it entirely, and put a 4WD skid steer on instead. Also weld on a belly pan to help keep sand out of the internals, if there isn't a pan already.

The go-kart tires might work OK for use on sand, too, if the robot is fairly light.
