Here is a video of our minibot prototype:

Right now our robot uses just one motor and 4" wheels and back drives on the way down way too fast. However when we shunt the motor, after it switches off at the top, it comes down nice and slow. If teams haven't figured out how to get it back down safely, I suggest you add a dpst switch that turns off motor power and at the same time connects the two ends of the motor together for a slow return.
