Canadarm 1 and 2 where both robotic arms designed to operate in space, doing task such as moving heavy objects, retrieving them, and even repairing stuff on the space station.
Canadarm 1, Canada’s huge technological advancement, was launched in space on the Space Shuttle Columbia (STS-2) on November 13, 1981. The design and building of the arm, also known as the Shuttle Remote Manipulator System short for RMS, marked the beginning of NASA and Canada’s space program relationship.
The Shuttle's Canadarm took to space for roughly 30 years of successful missions until the technology was finally outdated. Along with the Space Shuttle program after mission STS-135, this set the robotic arm for its 90th flight on July 2011. The arm's legacy lives on, as though it is gone, it still today has given Canada a good reputation as well as it gaining bonds with NASA and ISS (international space station).
Canadarm 2 had to big expectations although defiantly met them, as they made vast improvements like increasing the joint rotation, stronger build, and is even able to be repaired on space. However these are just a fraction of the improvements made, however what kind of impact did this arm leave on Canadians and even the world.
Canadarm 2 has created an even stronger bond with the ISS and Canada’s space program, proving further that it wasn’t a fluke and Canada has technology to offer in space. Canadarm 2 is a lot more complex and is a lot more efficient justifying its place in the ISS permanently. As mentioned earlier it can be repaired in space and do tricky task, sought out to be technology ahead of its time. The arm itself can act like an “inchworm” helping to move heavy objects, and even help astronauts move in space, at an efficient rate therefor being a very important machine in the ISS, and proving is rightful existence there as well.
As you can see Canada’s arm 1 and 2, were both very important and were landmarks in space
