Professor Dennis Hong from Virgina Tech gives this interesting TEDx talk on My seven species of robot. His humanoid robots are a amazing and can play soccer. These robots known as DARwIn-OP (Dynamic Anthropomorphic Robot with Intelligence - Open Platform) won the 2011 RoboCup which was a international challenge with 24 teams competing.

Update: You can find more information about DarwIn-OP from Robotis and it sells for $12,000 (I think).
