Gotta be a better way to design robotic limbs than hinged rigid metal plates and rods, and stepper-motor software. Like, flexible plastic solids with tension wires ('tendons') embedded in tubes. Let an AI figure out how to pull them to create locomotion. That took only a few seconds to think of. I'd love to see that tried.
