PR2 bakes a cake

Another popular robot for research and development is Willow Garage's PR2, pictured here mixing cookie batter at MIT. With wheels, two arms, and cameras, it can navigate autonomously. Inside the PR2 is open-source software geared at creating a more common platform for programming robots, which often have proprietary software. Note how this PR2 is augmented with a Microsoft Kinect game console controller on its "head" to give it three-dimensional vision.
