If you ever wonder what you could actually do with a nice arm… well, I had one for a while, and the following is the best I could come up with at the time. A fun little video:
Heh, the video is a little deceptive. The arm had no vision capability, so I faked it. The dominos only look like they are sitting in a random pile. Actually, they are sitting in very precise positions, so the arm would find them correctly when it ran a program I built by pointing the arm at the locations using the joystick.
