The SSRMS is the Space Station Remote Manipulator System, now officialy named Canadarm 2*. It is similar to, but bigger than, the space shuttle's robotic arm. Used primarily to build Space Station Alpha, move large loads and help dock the shuttle, it is 17.6 m long in full extension and has 7 motorized joints. The SPDM - Special Purpose Dextrous Manipulator (the so-called Canada Hand) - can be attached to one end to perform delicate operations with its two smaller arms. The other end can be mounted on a moving base that slides along rails. The official acronym for the the moving base is MBS, which stands for Mobile Base System, of course. Together with the SSRMS and SPDM, it constitutes the MSS (Mobile Servicing System). The SSRMS can also move in an inchworm fashion across the ISS thanks to its two identical grapple end points (the Latching End Effectors). This enables it to move from mounting point to mounting point, each of them providing control and power.

*Isn't this kind of unimaginative or at least uninspired considering other potential names, such as the lovely Canipulator...
