Here’s a one-motor coat hanger walker I spotted on Flickr. It uses the same single-motor hacked servo and BEAM bicore circuit as the Jerome Demer’s project I featured in my book, Absolute Beginner’s Guide to Building Robots, but the leg configuration is different than Jerome’s and my bots, and the center of gravity is shifted (on ours, the battery packs are on either side of the servo case, here they are behind the servo). I know that some builders from my book ended up getting better traction by adding some weight to the back of the servo case, so some COG shift can be a good thing. I’d like to see this one in action to see the walking gate/stability.
