tells about some recent activity with Dextre, the special purpose end-effector that's now in use on the Space Station. When I first heard about it in 1977, it was thought to be something more complex than just a gripper, but this is *amazing*! It can ride around on the tram while the Canadarm2 does other things, and it has small tools that it can use to fix things. It is also capable of teleoperation from Mission Control! The only limitation I see is that only one of Dextre's arms can be moved at a time, with the other locked in place. That's a minor limitation in my opinion. Good work, ROBO team!
