With such a high level of maneuverability, this arm is ideally suited for missions requiring autonomous capture and dexterous operations - from grabbing a satellite for on-orbit servicing, to extracting a boulder from an spinning asteroid, to assembling and servicing a large telescope in orbit, or setting up worksites on Mars for astronauts. Other features include a six-axis force/torque sensor at the end of the arm, and a flex harness that routes data, power, and video. Like your arm, the NASA servicing robot has "seven degrees of freedom"- a three-axis shoulder, a pitch actuator at the elbow, and a three-axis spherical wrist. Opening a door, grabbing a pencil, pouring a glass of water these are all are examples of simple, everyday tasks that use your arm. In particular, it builds off of previous NASA and DARPA investments in motion control, robotic software frameworks, flex harnesses, force-torque sensor, joint design, and flight operations experience. The system design heavily leverages the flight-qualified robotic arm developed for Defense Advanced Research Projects Agency (DARPA)'s Spacecraft for the Universal Modification of Orbits and Front-end Robotics Enabling Near-term Demonstration (FREND) programs in the mid-2000s. The Robotic Servicing Arm has extensive heritage from arms used in past Mars rover missions. Testing of an early version of the NASA Servicing Arm within the Robotic Operations Center.
