My robot pet takes its first "steps". Presumably more will follow. The hardware is from China (DealExtreme), the MCU is Arduino Uno (Atmel Atmega 328p), but the code is native C and only the Arduino bootloader is in use from the Arduino project. Buying the hw as a complete speeds up this kind of project nicely, so far the working hours are about 5h, from which 2h went on debugging out a broken cable.
