Canadarm3 will be Canada’s contribution to the US-led Gateway, a lunar outpost that will enable sustainable human exploration of the Moon. This highly autonomous robotic system will use cutting-edge software to perform tasks around the Moon without human intervention.


The smart robotic system will include several distinct parts:

a large, 8.5-metre-long arma smaller, more dexterous arma set of detachable tools


The next-generation Canadian robotic system will be designed to:

maintain, repair and inspect the Gatewaycapture visiting vehiclesrelocate Gateway moduleshelp astronauts during spacewalksenable science both in lunar orbit and on the surface of the Moon

Canadarm3 is designed to work autonomously. However, the system could also be operated by robotics flight controllers in Canada, or by Gateway crew during spacewalks.

Building on a legacy of leadership in space robotics

Canada is internationally recognized as a leader in space robotics. Our success in critical projects like Canadarm on the Space Shuttle fleet and Canadarm2 and Dextre on the International Space Station (ISS) have established Canada’s reputation for excellence.

Contributing Canadian robotics to an international project like the Lunar Gateway ...
