Meet PR2, Laundry-Folding Robot
PR2 is a Willow Garage robot that performs a valuable, and difficult, task for humans - folding the laundry. Professor Pieter Abbeel at UC Berkeley has PR2 started out on towels, which are somewhat easier than other items, but still it's a great start.
Science fiction fans may recall that this functionality was built into closets by Philip K. Dick in his 1965 novel The Zap Gun; see the entry for the handicloset.
Neat freaks might also like the Smart Pal robot hanging up clothes, this time on a hanger.
