Did you know?
While testing PR1, the Stanford AI Robotics group broke the robot more than once every day for a week. That is why so much reliability engineering and testing went into PR2.

History
PR1 was developed by Keenan Wyrobek and Eric Berger as part of the Personal Robots Program, led by Professor Kenneth Salisbury, at Stanford University. The goal of the program was creating "platform technology for research and development where robots do mobile manipulation tasks in human environments." The first prototype mobile manipulation development platform was the PR1. Following PR1, the PR2 robot was developed at Willow Garage. The program also originated the Open Source Robot Operating System (ROS).
