spent the day in the workshop today, after alot of thinking/measuring and weighing decided to fit 2 750 watt bosch motors which shouldnt be too tricky of a job, and remove the 4 400watt motors. this robot has 4 wheels, and i dont know if we should mount 1 motor at rear and one at front, or mount both at rear, (it needs to have the four wheels) but im wondering how will it drive with 2 motors at the back, and the front just free wheeling. (WOULD IT TURN?, i really doubt it) the wheels are similar to kart wheels. i didnt want to run long chains from rear to front if i didnt have to, just because im worried of snapping chains/reliability issues.
