(...) Thanks for the reply. If everything you say is true, I might use multiple white clutch gears on one axle, gear them to a differential and use the difference in torque to trigger a lever- which can activate the touch sensor.

The second set of arms on Mike's robot gives it better mobility. They make its overall tread length much longer, so it can treat stairs like a ramp instead of, well, stairs, and that makes it faster at climbing them. The arms also let it raise the (...)
