Robonaut is a humanoid robot designed by the Robot Systems Technology
Branch at NASA's Johnson Space Center in a collaborative effort with
DARPA. The Robonaut project seeks to develop and demonstrate a robotic
system that can function as an EVA astronaut equivalent. Robonaut jumps
generations ahead by eliminating the robotic scars (e.g., special
robotic grapples and targets) and specialized robotic tools of
traditional on-orbit robotics. However, it still keeps the human
operator in the control loop through its telepresence control system.
Robonaut is designed to be used for "EVA" tasks, i.e., those which were
not specifically designed for robots.
