Willow Garage's PR2 is a research robot that can be used out-of-the-box. The researcher no longer has to build hardware and no longer has to lay any software foundations. The open source technology enables him to get to work immediately. Willow Garage has given away 11 of these precious robots to reputable research institutions in order to increase the chance that their approach would become the guiding principle in the work that is being done here. The open source software is therefore being further improved and shared so that robotics can develop more quickly.
