Launch: April 2001
The Space Station Remote
Manipulator System (SSRMS), known as Canadarm2, is the first component of the
Mobile Servicing System. Although similar to the Shuttle Canadarm, this 17 metre
manipulator is somewhat larger and incorporates many advanced features, including
the ability to self relocate.
The arm has the capacity to handle large ISS modules and structural elements. It
will initially be used to assemble the Station. In the future, it will capture and
dock unmanned resupply spacecraft to the ISS and perform routine maintenance tasks.
Canadarm2 will normally move along the Space Station on the Mobile Base System, but
it also has the ability to "walk" from place to place by moving from one
grapple fixture on the exterior of the structure to the next, like an inchworm.
Canadarm2 is built with Orbital Replaceable Units (ORUs) which are components that
can be removed and then replaced by either an astronaut or the Special Purpose
Dexterous Manipulator. It is equipped with four television cameras, two mounted on
the booms and one near each tip. These cameras feed images to the astronauts
operating the arm from the Robotic Workstation inside the Station. An advanced
version of the Canadian Space Vision System improves the ability of Canadarm2
operators to keep track of the position, orientation and movement of payloads being
grappled.
