Following on from biped robot Junior I designed Tom, I decided to put the tilt rods at the back so if I ever put arms on then the rods wouldn't get in the way. Tom was tested with a Toddler control board and it turned out the 18swg piano wire rods were a little weak and I had to stiffen them before Tom would walk properly. The extra height of Tom and weight of the three servos means the 4mm plywood flexes at the wrong time and the speed and range of movements needs to be limited for smooth walking.

Tom is fitted with three GWS SO3 standard size servos and has bump switches on the toes. It was intended to fit IR sensor looking through the soles to detect table edges.
