pic: Whoops! Too much torque

[Alan Anderson]

The distorted shape of the wheel doesn't look like what I'd expect from either a rotational or side load. It looks like a simple impact to me. The robot might have taken a hard bounce, or it might have run the wheel into a proverbial brick wall at high speed.

Then again, the wheels were redesigned to handle greater side loads without breaking the spokes, and this might just be how they react now.
