Keenan Wyrobek from Stanford University is working closely with Willow Garage to continue the development work he and Eric Berger started while in their graduate studies at Stanford University. He shows off PR1 and explains the goals of the Personal Robotics Program and the next generation, PR2. Via Stanford University Website:
Kenneth Salisbury, a professor of Computer Science and of Surgery leads the Personal Robotics Program at Stanford with CS Assistant Professor Andrew Ng in coordination with the department's STAIR project. After about 18 months of work, they have developed a first prototype. It is remotely controlled now (eventually it will become more autonomous) but it is an early milestone on the way to releasing a practical, affordable and complete robotics platform.
