The PR2 self-calibrates on its own

The PR2 by Willow Garage is able to autocalibrate on its own with a new ROS (Robot Operating System) software application. This saves a considerable amount of time since the robot is left alone to work in order to calibrate its sensors. And here it is in the video demonstration below. For a reminder, the PR2 (Personal Robot 2) by Willow Garage is an open-source robot platform. The PR2 is provided with two pairs of stereo cameras, two cameras on its forearms, a high-resolution camera and a laser radar. That's a lot to be synchronized with the movements for calibration. Hence the current development of the PR2 Calibration Stack. http://www.youtube.com/watch?v=TwL4xqBLUdo
