This is a surgery robot called 'The Raven'. It's mostly camouflaged due to the large amounts of detail and contrast in the robot itself and in the background. The DV camera is going to be replaced by a pair of HD cameras that will provide stereo vision.
Multiple motors pull on cables seen in a later photo that control the manipulator end of the arm.
Blake Hannaford shows the arms that will replace the manually positioned arms seen in the previous photos.
