Skatebot is a skateboarding robot. He doesn’t do tricks, his main interest is moving forward. These are a couple of clips that show his progress. Last condition of the robot

“Spring repulsion” with two motors

First attempt: using worm gear as pelvis and a cogwheel as a knee. He isn’t particularly fast 🙂
