Did You Know?
Its creators named the robot Raven because it is black and comes from the Pacific Northwest. They say there was an acronym at one point, but they've forgotten it.
To test the robot, the researchers operate on dummies and pig carcasses.

The initial versions of the Raven platform were developed in 2005 as part of a DARPA project on the future of battlefield medicine. The Raven II was developed as an National Science Foundation project on collaborative research to advance surgical robotics. Seven Universities have begun research using the Raven II platform, including Harvard University; Johns Hopkins University; University of Nebraska; University of California, Santa Cruz; University of California, Berkeley; and University of Washington. These labs are investigating diverse problems involving surgical robots and related technologies and are able to share their experiences and breakthroughs using Raven as a common platform. Several more university and hospital research labs plan to join the effort soon.
