Number zero

Number zero (N0) is my first attempt to build a robot. This toy tractor is built from LEGO® Technic parts. (back view) The toy is driven by Java ME™ MIDlet on a mobile phone via Bluetooth (JSR82). Small board on the tractor comprise of BlueSMiRF Bluetooth class 1 module and Atmel's ATmega88 controller. Two 71427 LEGO® 9V motors are controlled by TI's SN754410 configured as a dual H-bridge.
