Have you ever heard of a robot from Willow Garage PR2 robots that can find their own power outlet when the time had to recharge the battery in it?

This time PR2 robots have other skills that fetch a beer from the fridge and given to people who request it.
Interestingly here, the robot can recognize faces PR2 any person (face recognition) and then will take the type of beer in accordance with the person's favorite beer without being told to know which type of beer desired. But of course the data must be entered first.

In addition to taking beer from the fridge and bring it to the requester, PR2 can also open a beer bottle with the corkscrew already available in parts of his body.
