First walking with gearbox chassis

Short recap: After building the quadruped with near-direct drive motors, I discovered that the lateral servos had insufficient position control authority to keep the robot standing up.  Thus I embarked on a now month long quest to design and build an integrated planetary gearbox.  At this point, I have enough gearboxes built for all the lateral servos, so it should be able to walk, right?

And tada!  It can!  Well, at least a little bit.  I’ve only spent a short while with the gearbox based chassis, and have a lot of work left to do.  However, here’s a quick video showing it walking around, slipping on a ruler, and almost falling over a few times.
