R2-IQ: Broken

Build Day 28:

Bent Axle

Over the weekend, while I was driving R2 around the show, it would turn to the right, but not to the left.  When I would try to turn left, the chain would jump on the gears on the center leg.  I didn't really understand why it worked one direction, but not the other.

Last night I decided to replace the chain with gears, and while rebuilding the wheel, I discovered one of the axles was very bent, causing the wheel to turn poorly.

Hopefully, I'll get the leg rebuilt (new design) and attached, tonight.
