To the RMS as far as operational modes, display panels, and CRT screens were concerned, while interfacing to a new and different type of hydraulic control hardware. The basic requirements for the RMSS were that it must behave identically
THE SPACE SHUTTLE FLIGHT CONTROL SYSTEM CALLED PASS SOFTWARE
Because of the completely different nature of the joint controls, the original RMS software was not usable except as a source of algorithms. was selected to provide the overall control program for the GSFC arm, called the RMSS (Remote Manipulator System Simulator), along with Electrologic of America (ELA) who provided the control electronics and drivers. In order to do this it uses a high pressure (4000 psi) hydraulic system rather than electric motors as on the RMS. The GSFC arm, for example, is designed to carry up to a thousand pound payload at its tip. Because of the need to work in a gravity environment and other specific design factors, the ground-based arms differ from the RMS and from each other. In order to plan for missions involving the RMS, there are also two ground-based versions of it, one at the Johnson Spaceflight Center in Texas (JSC) and one at the Goddard Spaceflight Center in Maryland (GSFC). This application was featured in Motion Control Magazine, V4 #7. The 50′ Shuttle Remote Manipulator System (RMS) Simulator at NASA’s Goddard Space Flight Center. Arm control, status information, and positional displays are provided both by a hard-wired panel containing control switches, status lights, and digital displays, and by a series of interactive status and control screens on the shuttle’s General Purpose Computer (GPC). Using the joysticks, an operator can command motion about any desired axis and the RMS software will makeĪll the co-ordinate transformations and complex calculations necessary to derive the needed command rates for each of the six joints.
The arm, formally called the Remote Manipulator System (RMS), has ten different modes of operation ranging from simple direct movement of the joints one at a time to very complex multi-joint motions directed by rotational and translational joysticks.

NASA’s Space Shuttle carries a 50-foot long, six-joint arm for use in satellite deployment and retrieval operations and to assist astronauts in servicing tasks such as the recent mission to repair and upgrade the Hubble Space Telescope.
