Ambler is a two motor walker with a one degree of freedom head. It is based on BEAM bicore technology and is highly positively phototropic. It swings it's head in the direction of brighter light and the body follows. The tactile sensors allow the walker to turn and reverse from objects. It operates on two 3VDC camera batteries. It's frame is made from hand made brass pieces bolted together with 2mm hex screws. It's three gearmotors are BG Miocros or Nihon lens motors and are roughly a 100:1 gear ratio. The bot sports many little details, such as a flip up custom PCB, indicator LEDs to show the controller pulses and mini shock absorbers on the front legs. The cost to build was roughly 80.00 US.
