Robot 3: Autonomous Sensor Platform 'Jimbo'

This is my first autonomous robot (he has a mind of his own!) And boy, what a wayward child he's been!
I built this to explore various sensors and sensor interfacing to the PICAXE-18M2 micro-controller.
His mission is to search for a magnet using Hall-Effect sensors, and to avoid obstacles like walls and cliffs using reflective IR (infra-red) sensors. When he encounters an obstacle, he has to stop, back up, turn a random angle, and proceed forward again until he finds the magnet. When the prize if found, he stops and blinks a green LED. It took 4 tweeks of the program to get it right.
