Here is a video demonstration of a Willow Garage PR-2 robot making a single large cookie. Willow Garage also makes the robot that UC Berkeley researchers taught to fold laundry and pair socks. This baker robot was programmed by Mario Bollini and Daniela Rus of MIT's Distributed Robotics Lab. From Nick Bilton's Bits blog at the NYT:
In June, the same researchers programmed the PR2 to place grocery store products in a shopping cart. They also taught the robot to mix a bowl of ingredients with the goal of making breakfast, obviously not for the robot to eat."Your Very Own Cookie-Baking Robot" (Thanks, Mumbles Mumbach!)
