The folks at Willow Garage taught their p2r robot to play pool. Pretty impressive feat for only one week of work:

With only a small team of developers and a week’s worth of development, the PR2 can now play pool! The “Poolshark” team started last Monday and began making shots on Friday. The PR2 won’t be hustling you in pool halls anytime soon, but it pocketed five shots on Friday before the team decided it was time to celebrate.
