Re: Be afraid... Be VERY Afraid

I am just going to guess that it is some sort of mechanical automatic transmission. That shifts into a high torque mode when placed under additional load (such as being pushed or accelerating from standstill). Another possibility is that when this runs into something the wheels end up lifting up the robot to allow it to climb objects such as stairs or the barrier from this year easier.

Anyways beautiful model, I appreciate the detail and the actual teeth on the belt.
