Robot Centipede - PREVIEW VERSION

This is the next video about coming up with an idea for something I’ll eventually make big enough to ride on. I really want to make a giant rideable land-worm, and last year I made an eight-wheeled snake bike which bends to steer. That had wheels but I’d really like to build something that can move in an unconventional way or walk on legs. I’ve been experimenting with wave drives, the first one used a spiral shaped former inside a flexible track, and I tried a cam-shaft driven design a few weeks ago. At the end of that video I mentioned it might be better to turn all the cams around 90 degrees and use them to drive legs in a wave formation. This leg mechanism is half of the walking mechanism I used in each unit in my omni-directional walking machine, so I decided that perhaps I should just use the whole mechanism and line a bunch of those up to make a centipede. I got this leg mechanism idea from the DIY walkers YouTube channel which you should check out. I want to make this machine four or five segments long and drive the whole thing from a single motor, so I’ve designed universal joints to link all of the sections, and a gearing arrangement to drive everything from one overhead drive shaft.
