Station crew members will be able to operate R2, as will controllers on the ground; both will do so using telepresence. One of the improvements over the previous Robonaut generation is that R2 does not need constant supervision. In anticipation of a future destination in which distance and time delays would make continuous management problematic, R2 was designed to be set to tasks and then carry them through autonomously with periodic status checks. While not all human range of motion and sensitivity has been duplicated, the robot's hand has 12 degrees of freedom as well as 2 degrees of freedom in wrist. The R2 model also uses touch sensors at the tips of its fingers.
