Anyone using machine vision to try to work around the positioning problem? Seems like working solely from proprioception is way harder than proprioception plus

  Yes, there was a robot arm on HN about two weeks ago which had a QR code target on the end effector. Something that doesn't seem to have caught on is putting tiny cell phone cameras in the end effector, so you can fine-tune positioning.

    The parent comment makes a good point. If accurate positioning is an issue it seems like you would want a closed loop control system that measures and optimizes for that. The position measurement itself could be made using machine vision or perhaps more precisely using lidar or some other technique. I've even wondered if that might allow you to build a less rigid and hence less expensive CNC mill.
