A shout out to Canadians for putting your versatile robotic Space Arm on your $5 note: https://twitter.com/neiltyson/status/428547577315729408http://www.bankofcanada.ca/banknotes/bank-note-series/polymer/Canadarm2 and Dextre debut on new Canadian $5 bank notehttp://en.wikipedia.org/wiki/Canadian_five-dollar_notehttp://www.bankofcanada.ca/wp-content/uploads/2013/05/design_5.pdf
" Robotics innovation is Canada’s ongoing contribution to the International Space Station program and demonstrates our commitment to space exploration. The Canadian-built Mobile Servicing System is the sophisticated robotics suite that helped to assemble the International Space Station in orbit. This system consists of Canadarm2, Dextre and the Mobile Base.
On board the space station - a permanent orbiting research laboratory - international partners conduct scientific experiments, many of which result in an enhanced quality of life on earth. Canada’s contribution to the space program evokes pride and sparks the imagination and curiosity of our future leaders in science and technology.
Canadarm2 is the centrepiece of Canada’s contribution to the International Space Station. The 17 metre-long robotic arm plays a major role in the assembly and maintenance of the station. It routinely makes repairs, moves equipment and supplies, captures and docks unpiloted spacecraft and, at times, supports spacewalking astronauts. Launched in April 2001, Canadarm2 is a larger, more advanced version of the original Canadarm, which was retired in July 2011.
Dextre, which is short for Special Purpose Dexterous Manipulator, is a sophisticated two-armed robot that attaches to Canadarm2. It acts as a space handyman and performs routine upkeep and repair work outside the International Space Station so that astronauts can devote their time to scientific research. Launched in March 2008, Dextre is sometimes referred to as “the Canada Hand” since it rides on the end of Canadarm2 and manipulates small components that require precise handling.
The Mobile Base is a moveable work platform and storage facility. It serves as a base for Canadarm2 and Dextre.
The astronaut depicted on the $5 note represents all Canadians who have contributed to the space program and the scientific research conducted on board the International Space Station. This image also depicts the courage and commitment of all Canadian astronauts and highlights the role they have played, and will continue to play, in inspiring youth to get excited about science and technology.
