The Walker is the first robot I ever built. Most of my 'robot room' equipment was bought for it, so it's also the most expensive. It's also the least working of my robots at present. So I'm thinking of renaming it "Cash Cow".

Technical Data:

The Walker is an evolution of an original 4 legged robot which was build with only 8 servos and an OOPic, this proved to be too little hardware, so more servos per leg, and a bigger better controller have sorted those problems out. I still haven't got it walking yet due to the amount of time I have available.

 
The Controller is a Dallas DS80C320 I got the board from Robot-Electronics in the UK It's a good board because you can download a program to it without any problem at all it loads it into RAM so you don't have to waste Flash RAM or burn EEPROMS all the time. Robot-Electronics have lots of good stuff at their sie, and it's always worth a look to see what's new. If you want a ue320 or other type, they are available on request.

Parts Source:

The legs are made of the servos glued together using bits of left over strip board as splints.

The feet are rubber feet for walking sticks, which happened to fit nicely when wedged in with glue gun sticks.

The body is made from L-shaped extruded aluminium build into a rectangle, the legs are attached directly to it. An old PCB us used as a base for putting the Controller and power on, the Servo control lines go through the body in-between these two.

Still, Here are some pictures of it:
