(...) How about curved railway track? IIRC that gives you pieces about 16 studs long (little less for inner rail, more for outer) with an angle of 1/16th full circle (22.5 degrees). You can then call the beast "big foot" :-) Jürgen (24 years ago, 23-Mar-01, to lugnet.robotics)

What kind of ankle joint? A motorized one, or passive one? If it is the first type I think the leg will be too heavy to be moved quickly. That is critical since the robot falls onto itself.
