Canadarm History
• NASA needed a Shuttle Remote Manipulator System (SRMS) in the early ‘70s
• A small Canadian firm, DSMA Atcon (Now MDA) caught the eye of NASA
• One of the major contribution from Canada

Purpose of Canadarm• Deploy satellites for
operational
• Receive satellites for repairing
• First generation of Canadarm was mounted on each space shuttle
• A total of 5 first generation Canadarms were produced
• 1 were lost in the explosion

Canadarm
• First Canadarm was deployed in November, 1981 during STS-2
• Main mission is to help deploying space object
• After the Columbia incident, cameras and sensors were added

Canadarm
• Apart from controlling inside the shuttle, the arm can also be controlled from the End Effector
• The technology of the space robotics arm were also used for medical purposes
• It increases accuracy, efficiency and quality during surgery

Thermal Protection System
• The thermal protection system helps maintain the temperature inside the Canadarm
• In extreme cold temperatures it will heat up to maintain a stable operating temperature for the arm
• Kapton layers, Dacron scrim cloth and Beta cloth were used on the outside of the Canadarm
• Similar materials were used on the astronaut suits

Retirement of Canadarm
• The first generation of Canadarmwas retired after the last space shuttle mission
• All remaining arms were being stored back on Earth

Canadarm2
• Launch in April, 2001 during STS-100
• Canadian astronaut Chris Hadfield helped installing the Canadarm2 on the ISS
• Ground control is responsible to coordinate Canadarm2 activities

Canadarm2
• An upgraded version of Candarm that carry heavier payload, more cameras and sensors to detect damages
• Similar to the first generation of Canadarm, it is able to control the arm from the ISS or outside the space station
• This arm can repair in outer space due to the reason it is mounted on the ISS for a permeant period
• Canadarm2 also assists docking for space shuttle
Canadarm2• Apart from docking and
retrieving satellites, Canadarm2 also help the expansion of the ISS
• The ISS kept expanding since the deployment of Canadarm2

Mobile Base System
• The mobile base system was installed to allow the Canadarm2 to move on a rail truss
• This allow the arm to reach to more places on the ISS
• The MBS was installed during STS-111

Canadarm Comparison
Canadarm
• Mounted on the space shuttle
• 5 were made
• Less cameras
• Less movement compare to Canadarm2
• Lighter and smaller than Candarm2
Canadarm2
• Mounted on the ISS
• Only 1 was made
• Heavier and longer than Canadarm
• Can carry heavier payload compare to Canadarm
The Next Generation Canadarm(Canadarm3)
• Currently the CSA are developing the next generation Canadram
• Same size as Canadarm2 but lighter and more compact for future spacecraft
• It is unknown when the new Canadarm will deploy into service

Future Improvement• Ground control can override the
controlling system in case of emergency
• Can fit into Soyuz spacecraft or Orion spacecraft
• Add sensor to detect incoming space debris
• Of course, more funding would help!
