If you imagine robots to be slow, lurching machines, think again. Sure, Honda's Asimo isn't going to beat anyone in a race, but that's not the only robot on the block. This robot hand at the Ishikawa Komuro Lab manages to bounce a rubber ball far faster than any person can.
I'd like to think that there are positive uses for this, but we all know that when robots can move this fast, it's going to end badly for humanity. But at least we have entertaining YouTube videos along the way!
