An advanced research robot  capable of navigating through environments. 

The PR2 robot is a robotics research and development platform. PR2 combines the mobility to navigate human environments and the dexterity to grasp and manipulate objects in those environments. The PR2 is an open platform and can be adapted to meet researchers specific needs.

PR2's arms are backdriveable and current controlled so PR2 can manipulate in unstructured environments. It's arms have a passive spring counterbalance system so the arms float even when the power is off. The robot's wrist has two continuous degrees of freedom and lots of torque so PR2 can manipulate everyday objects from doors to frying pans. PR2's gripper can grasp everything from towels to tea cups, and brooms to brew
