Photos: Toyota's mobile, musical robots

The violin-playing robot has a total of 17 joints in both of its hands and arms and, Toyota claims, can attain "humanlike dexterity." (A couple years back, the company introduced a trumpet-playing robot.) At Thursday's unveiling, the 56-kilogram machine performed Elgar's "Pomp and Circumstance," but the company really is grooming it for domestic duties, nursing, and medical care.
