Robot Army

Some more notes on the latest:

• 0.22" instead of 0.23". (Or maybe even 0.24?)
• Confused bearing flange and body diameters.
• The motors have M3 screws. I even got to buy M2, M2.5, and M4 screws to figure that out.

I've also decided to resurrect the Logo computer system. I hadn't been planning on having a whole x86+hdd system onboard so this is starting to push the weight limits imposed by the relatively small drive motors. Fortunately the design would be pretty easily modified to accept larger side-by-side motors instead of smallish end-to-end motors, if it comes to that.
