Programmable Robot

One of my claims to fame was a programmable robot I designed (which see), published in Australia in 2004, and in the UK in 2007. It was described like this: "This programmable buggy is fully manoeuvrable and has PWM speed control and H-bridge MOSFET gearmotor drivers. It also sports bump and respond, random motion, programmable sound, light sensing, and EEPROM byte-wise programming." OBSERVATION: I programmed it so that when the Australian publisher unwrapped it and put it on the floor, it wiggled its rear, played a few lines of "Waltzing Matilda", then did a dance. (I have other things to amuse me nowadays).
