I built a tank with two of these drives which worked fairly well. Each of the drives consists of a flexible track to make the wave shape, and inside is a spiral shaped piece of steel which rotates and shapes the flexible track as it does so. I got this idea from another YouTube video, but this one is a single wave drive with steering wheels at the front. This mechanism is a bit like a screw tank, but it allows us to manage the sideways friction from the screws because they turn inside the track, rather than having them running directly on the ground. But what actually makes it go along? It seems clear that there’s a wave moving backwards or forwards and pushing the tank in the opposite direction, but surely each segment of the track is actually stationary and just moving up and down. I had a lot of problems shaping the spiral parts properly in this version, I could probably have gone about it differently, but a few people in the comments suggested a different approach which was to use a cam shaft to make the wave instead of the spiral parts. If the cam shaft is mounted above the track then it’ll also help with ground clearance which was a problem I had because I needed a pulley to drive the rotary motion. To start with I’m not going to design the track, so we’ll just push some flat plates up and down and see if that drives it along.
