We stumbled onto one of [Nik Melton]‘s projects, an Omni-car. It is omnidirectional, meaning it can go any direction at any time without having to turn. The body was designed by him, then printed with a 3D printer. The control scheme is what interests us though. He has found a simple way to wire it to get the job done. Sure you can see that it suffers from some pretty bad “drift” when trying to go in a straight line, but overall, we think he pulled it off well.
You might want to take a few moments to look around his project page. This guy has done a bunch of fun stuff like delta robots, strange hybrid wheel/leg robots, tesla coils, and arm mounted flamethrowers. Judging by the videos, he’s pretty young too. We think his guy has a bright future ahead of him.
