Overview

The PR1 (Personal Robot One) is a powerful and versatile mobile manipulation research platform designed for robotics development and application development. It features backdrivable, passive spring counterbalanced 7-degrees-of-freedom arms, a telescoping spine, mobile base, and onboard computers controlled together at 1 kHz for fluid whole-body motion. The robot was instrumental in jump-starting a robotics revolution and helped originate the Open Source Robot Operating System (ROS).
