The PR2 (Personal Robot 2), developed by Willow Garage, is a versatile research platform designed for robotics experimentation and development. It features two 7-DOF robotic arms with grippers, a mobile base, and a sensor-laden head equipped with cameras and a tilting laser scanner. The robot uses the ROS (Robot Operating System), which Willow Garage pioneered, making it a cornerstone for robotics research worldwide. Its modular design and open-source software make it highly adaptable for tasks like object manipulation, navigation, and human-robot interaction.

Standing approximately 1.65 meters tall and weighing about 225 kg, the PR2 is equipped with a rechargeable battery that allows for extended operation. It has been used in labs globally for diverse projects, including folding laundry, fetching drinks, and collaborative robotics. Although no longer in production, the PR2 remains influential in robotics education and research.
