Overview
The two-armed robot Willow Garage built alongside ROS. It did laundry, fetched beer and opened doors in the early 2010s. Only a few dozen were made, mostly for universities through a beta program. Willow Garage closed in 2014 and Clearpath took over support. Surviving units sit in museums and labs.
