This robot make use of the PICAXE-28X2 shield base which has been designed to be compatible with almost all 'shield modules' used with the Arduino system. On top of the sheild base is an Instant Robot Shield that is designed to enable you to rapidly create a robot, just plug in jumpers to motors, switches and LEDs and off you go. PICAXE microcontrollers, programming software and information can be found at http://www.picaxe.com/ with a very helpful active forum.
The robot is currently working from a Sony TV remote control via the built in IR receiver on the shield.
The body for the robot was laser cut from 3mm acrylic this is the drawing in 2D Design
