Physical gaussian surfels - such a cool idea:
Edge robots It would be interesting to build a reconfigurable robot out of a large number of linear actuators making up the “edges” of a triangulated shell. A simple icosahedron could wiggle around like a more rigid version of NASA’s Super Ball Bot, but with a few hundred edges, you could make a mesh that turns into a low-poly video game character. And walks. With thousands of tiny edges, you get something that starts to look like movie nanotech. Coordinating hundreds of actuators that are tightly constrained would be challenging, but not intractable. Edges could only grow or shrink by less than a factor of 2, and as a shell, you would have to prevent the surfaces from ever flattening out, where they would be unstable. If you give up on being just a shell and add internal links, the mechanical performance could be greatly improved, and you could freely change convexity. Analyzing the range of animations you could keyframe with a given topology is an interesting problem even ignoring dynamics; learning to walk would be a fairly aggressive MuJoCo simulation task. There would be a strong desire to have specialized links of various sizes, but you could do quite a lot with a single universal edge and vertex set. I don’t know if it would actually be good for anything, but I was thinking about Iron Man armor…
