The Canadian Space Agency (CSA), which invented and made the International Space Station's 30-year robotic Canadarm project, is working on lunar and Mars robot rovers. It recently unveiled five rover prototypes and put them through their paces on the agency's testing terrain, which simulates the surfaces of Mars and the moon.
The new lineup includes four lunar rovers -- the Micro-Rover Platform with Tooling Arm, the Kapvik Micro-Rover, the Artemis, and the Lunar Exploration Light Rover -- and the Mars Exploration Science Rover. They are in addition to the Juno and Rex rovers, which have been operating since 2010.
The CSA also developed some spinoff technologies resulting from its rover development work. They include the SL-Commander automated electric all-terrain vehicle, a fuel cell, and the Q6 mini-computer.

The CSA's Rex rover has a robotic arm that simulates collecting Martian rock and soil samples. It travels at 4cm/sec (1.57inch/sec). On its six aluminum or rubber wheels, the rover can navigate over obstacles up to 15cm (5.9 inches) high and climb slopes of up to 10 degrees. Rex weighs 140kg (308.64 pounds) and measures 152 x 142 x 76cm (59.84 x 55.9 x 29.92 inches). It can carry up to 30kg (66.13 pounds) of science payloads. In 2010, the CSA jointly field tested the rover with NASA at the Flagstaff Meteor Crater in Arizona.
