Thanks for the suggestions. I have decided to name this bot Box-E
Too many sensors? Didn't know that was possible! $3 on ebay, so why not? Even with 4 ultrasonics, I'm still at less than half the cost of one PING sensor.
The top box is a Stellaris Launchpad box, the bottom box is an MSP430 Launchpad box. The shame is that there isn't a single TI part in the robot, at least as of now. The microcontroller is ATMEL and the motor driver is Toshiba. Sorry TI
The box is not a great look, but I find it to be a great platform while I figure out what I want to do. Kinda like breadboarding the chassis. It's my second bot, so I'm still learning what design consideration to keep in mind.
