The Robotic
Workstation (RWS) provides the operator interface to control and receive
data from the Space Station Remote Manipulator System (SSRMS), also known
as the Space Station robot arm.
On Flight 6A, both workstations are brought up and
then placed in the Lab. To provide
operators with out-the-window viewing, the second RWS is moved into the
Cupola when it arrives on Flight 14A. During operations, one workstation
is active (prime), while the second is in monitor mode or powered down.
The active RWS has primary control of MSS functions, while the backup
only provides emergency stop, control/display of additional camera views,
and feedback of function status. If the prime RWS fails, the second workstation
can transition from monitor mode to active.
