Yet Another Particle-Bot Prototype

Here's another Particle-Bot prototype.  This one is a lot closer to how I see the final robot.  Using pager motors without a gearbox really cuts down on the unit cost, but to really be able to evaluate the design I need to build a better chassis.  I'm currently thinking 3D printing would be a good choice.

Two Particle-Bots, and two programmers, two nights work.
