Three PR2 "alphas" running around Willow Garage

armless pr2Three sets of bases, spines and heads have been assembled and are under intensive testing at Willow Garage.  These robots are complete except for the modular arms, which will be finished next month.  The navigation stack from ROS has been implemented and is currently being refined.  The robots are already able to navigate the hallways in the building autonomously.  Meanwhile the prototype "breadboard" arm is attached to the old breadboard body, so that the arm control software can be developed and tested in advance.
