Bluetooth Controlled Mobot

Bluetooth Controlled Mobot using Z8F0823 and LMX9838.

It's supposed to be my entry for a friendly competitions of "sumobots". But, I wasn't able to make it "autonomous" on time for the event. It only have four sensors on each corner to detect "black" lines, but no sensor for detecting an opponent. And so that I can still test the hardware, I just made it manually controllable by using my phone's bluetooth. The bluetooth module is the same circuit I used in my BT minibot . I also used the same python S60 script for my N6120c (Symbian phone) controller.
