This one was more interesting to read about. Someone at MIT (presumably a group) is working with a Barrett WAM Arm to test grasping algorithms. The idea being they want to be able to make sure the arm's programming is right for household things like helping put groceries away.
The cool part - to me - is they named their arm Lludd, after Lludd Llaw Eraint otherwise know as "Lludd of the Silver Hand." Lludd is a Welsh folk hero who lost his arm in battle. It was replaced by one made of silver. Neat huh?
