- Canadarm2 is also called as Remote Manipulator System
- It is a part of Canada’s contribution to the International Space Station(ISS)
- This 18-metre long robotic arm of ISS is used for undertaking maintenance works and “catching” visiting spacecraft.
- It was developed by the Canada Space Agency(CSA) for the International Space Station.
- It is operated by astronauts in the ISS or by ground team in the Canada Space Agency or NASA.
- The arm recently suffered a minor damage because of a piece of orbital debris in the space.
- This debris was too small to be tracked by the ISS, which monitors objects that are softball sized or bigger potential collision.
- While the impact has left a hole on this arm, still its performance remains stable and unaffected.
- Canadarm2 is the successor to the original Canadarm system developed in 1970s.
- Canadarm is the name given to a series of specially outfitted robotic arms designed by the Canadian Space Agency(CSA) and installed on NASA space shuttle during shuttle missions to aid in the construction and repair of the ISS.
How does it work?
- Each end of Canadarm2 features an identical hand known as “Latching End Effector”.
- These pieces contain cables that tighten to ensure a strong grip.
- They allow the robotic arm to firmly grasp objects or latch itself to the station.
Major Components of Canadarm2
- The Space Station Remote Manipulator System(SSRMS) or Canadarm2 is the 57.7 foot long robotic manipulator arm that attaches at multiple points along the station’s main truss and assists in a various tasks.
- The Special Purpose Dexterous Manipulator(SPDM) or Dextre or Canada Hand is a smaller robot arm that can attach to the Canadarm2, the Mobile Base System, or directly to the ISS.
3.Mobile Remote Servicer Base System
- It is a platform for the Station robotic arms to anchor to.
- The base system moves along the station’s main truss on rails.
4.Latcing End Effector.
- Canadarm2 has two hands on either end of it.
- Each hand is called as Latching End Effector.
- It is used to grab and manipulates the supplies, cargo and astronauts that the Canadarm2 moves around the ISS.
- Helps with ISS maintenance.
- Move supplies and astronauts.
- Catch visiting vehicles.
- Perform “cosmic catches”
