Head of the robot DART, the predecessor to Robonaut, a robotic astronaut developed by NASA at the Johnson Space Center in Texas. In the first, developmental setup, the robot DART (Dexterous Anthropomorphic Robotic Testbed) had its head and hands joined to several long, immobile, pipelike cylinders. Later models are much more closely patterned on the human body. From the book Robo sapiens: Evolution of a New Species, page 131 bottom.
