__The basic idea is this:__ six wheels, all 180-200rpm ~25mm high power motors with shaft encoders. The two center wheels are driven but not steerable. The four corner wheels are mounted on ServoBlocks so they can be steered. Rather than a Rocker-Bogie, we opt for the simpler Triple-Rocker. This requires two identical rockers on the sides and one almost-the-same rocker arm at the back, each with dual ball bearing mounts. There are no differentials or connections between the rockers (as in the Rocker-Bogie design).

There will be three pairs of motors, three dual motor controllers, and three batteries. Basically three separate systems, with two I2C isolators communicating between. The front and back motor/controller pairs (with the steering) are effectively identical. The central system won't have the steering, so that's where we'll mount the controller (likely a Raspberry Pi) and the rest of the sensors.
