An open-source robo-surgeon

The Economist, March 2, 2012
The Raven is compact, light and cheap (relatively speaking) at around $250,000. Originally, it was developed for the American army by Dr Hannaford and Jacob Rosen of the University of California, Santa Cruz, as a prototype for robotic surgery on the battlefield. More importantly for academics, it is also the first surgical robot to use open-source software. Its Linux-based operating system lets anyone modify and improve the original code, creating a way for researchers to experiment and collaborate.
