I recently completed the Pololu Maestro hexapod design. They did a great job with the build guide, bill of materials and the overall robot's design. It's simple yet fairly high performing for its specs and total cost to build. I built in a few performance upgrades including using stiff steel music wire for the legs instead of paper clips. I bound the wire to the servo horns with poly thread and CA glue- it makes a very strong bond. I mounted the IR sensors up a little higher using a triangular chunk of styrofoam. I highly recommend this project if you're looking for a budget minded fun building "scratch built" style bot. More details on
the Pololu project page.
