Canadian Space Agency Builds a Fleet of Rover Models

LONGUEUIL, Quebec — Space agencies around the world are discussing how to coordinate the next phases of the space exploration program. As an active partner in this endeavor, the Canadian Space Agency (CSA) is focusing its efforts on developing space science and technologies that serve national priorities and play a niche role in international missions, including the robotic and human exploration of the solar system, and advanced exploration technology development.

Canada’s minister of industry, Christian Paradis, and the president of the CSA, Steve MacLean unveiled a fleet of models on October 19th. The rovers performed robotic demonstrations at the CSA’s analogue testing terrain, the largest of its kind in the world, which replicates the surface of the Moon or Mars.

Canada’s Economic Action Plan announced in Budget 2009 provided $110 million over three years for advance robotics and space exploration technologies, of which $60 million was allocated to the Exploration Surface Mobility project. These funds were invested in a total of 33 challenging high-technology contracts to over 40 Canadian companies and a dozen universities.

The following terrestrial rovers and their associated technologies are being used in a set of testing, demonstrations and deployment activities to assess and improve the developed technologies and ensure the mission objectives are achieved and refined.

Terrestrial prototypes of Lunar Rovers

Juno (Upgraded)

The Juno rovers are actually a family of 5 individual rovers bearing the same name. These highly versatile rovers each consist of a base, three types of wheels and a set of tracks (similar to a snowmobile) to allow the rover to test science equipment in a variety of terrains. The sturdy rover can be operated remotely (tele-operated), is able to carry nearly as much as it weighs, and is surprisingly agile and quick. JUNO rovers have been in operation since 2010, and received a significant upgrade with an investment under the Economic Action Plan. Juno rovers were successful deployed during two NASA-led field tests on the rocky slopes of a volcano to simulate missions to the Moon (2010, 2012).

• Mass: 300 kg
• Can carry 275 kg of science payloads
• Max speed: 13 km/h (4 speeds)
• Uses rubber, metal or iRings wheels or metal tracks
• Can be linked in a tandem configuration
• Prime Contractor: Neptec Design Group
• $1.33 million was invested to upgrade the Juno rovers and increase their capabilities
• Partners: Ontario Drive and Gear Ltd. (OGD), McGill University, CrossChasm Technologies, University of Ottawa.

Lunar Exploration Light Rover (New)

One of CSA’s new rovers, the Lunar Exploration Light Rover is designed to be a terrestrial prototype of a mobile Moon lab. It can be fitted with a robotic arm to allow it to scoop up samples for analysis on board. The largest and the fastest rover in the CSA’s fleet, the six-wheel rover was also designed with the option of upgrading it to transport humans to test how astronauts might operate the rover while working on the surface of the Moon (much like the Moon buggy used during the Apollo missions). A long-range explorer that can roam up to 15 km from its home base, the rover can be tele-operated from a remote location, and is semi-autonomous (the rover uses its on-board lidar to scan its environment and navigate around obstacles without human assistance).

• Mass: 900 kg
• Can carry 300 kg of science payloads
• Top speed: 15 km/h
• Prime contractor: MacDonald, Dettwiler and Associates (MDA)
• Contract value: $14.6 million including SL-Commander (see below)
• Partners: Bombardier Recreational Products (BRP), UTIAS-ASRL (Autonomous Space Robotics Lab), Ryerson University, University of Western Ontario, York University, University of Winnipeg, University of British Columbia, McMaster University, Hamilton Sunstrand, University of Toronto, Turquoise Technology, University of Wisconsin-Madison, Penguin ASI

Artemis (New)

One of the CSA’s new rovers, Artemis is a light-weight terrestrial prototype of a lunar exploration rover. It can either be operated by a human nearby or at a remote location, or use its onboard sensors to scan its environment and navigate without the need for a human operator. Its unique wheel system makes it very nimble in tight spaces. The rover’s wheels use skid-steering to turn (much like a tank), with the wheels on one side pushing while the opposite set pull. This allows the rover to spin 360 degrees on the same spot. Artemis’s powerful battery can last for a full day of roving. The rover also carries a set of solar panels to power science instruments on board. Artemis has already completed its first field test in cooperation with NASA in July 2012.

• Mass: 230 kg
• Can carry up to 150 kg of science payloads
• Max speed: 4 km/h
• 4-wheel drive
• Prime contractor: Neptec Design Group
• Contract value: $13.5 million
• Partners: ODG, COM DEV, NGC Aerospace, McGill University, ProtoInnovations, Provectus

Kapvik Micro-Rover (New)

Click to Enlarge

Weighing in at a mere 40 kg, Kapvik (Innu for “Wolverine”) is one of the CSA’s two micro-rovers. Micro-rovers can work as helpers for humans (for instance, to help an astronaut dig) or even for other larger lunar rovers. Their small stature allows them to scout out tight spaces (like caves or crevices). Kapvik can even be tethered to a larger rover and lowered down slopes of up to 65 degrees (compare to the steepest ski jumps, which are no more than 40 degrees!).

Kapvik’s robotic arm does double-duty as its mast, allowing the rover’s sensors to scan and map its environment to search for minerals, water or ice. Once the fully autonomous rover spots an interesting target, it can make its own way to the site, deploy its robotic arm, dig a trench and deposit soil or rocks into the two small collection cans on either of its “shoulders”.

• Robotic mast and miniature imaging sensors
• Rocker-bogie suspension system
• Tele-operable and full autonomy
• Travel range greater than 500 m
• Unaided operations on slopes up to 30 degrees
• Tethered operations on steep slopes up to 65 degrees
• Robotic mast with end effector that enables acquisition of selected samples and subsurface trenching
• Multispectral imaging UV-Vis/IR sensors provide in situ analysis and 2-D mapping of mineralogy, water/ice content and planetary resources
• Prime contractor: MPB Communications
• Contract value: $2 million
• Partners: Carleton University, Ryerson University, UTIAS, MDA, University of Winnipeg, Xiphos Technologies

Micro-Rover Platform with Tooling Arm (New)

Click to Enlarge

One of the CSA’s two micro-rovers, this pint-sized rover can act as a helper robot for an astronaut or work in tandem with a larger rover. Micro-rovers can be used to investigate small spaces where larger rovers or humans can’t fit. A micro-rover can even be tethered to a larger rover so that it can travel down slopes of up to 65 degrees. This pint-sized rover’s special talent is its ability to travel over rocky terrain. It can be modified to use wheels or tracks as needed, and can even lower or raise its centre of gravity for increased stability on tricky terrain.

• 30 kg micro-rover platform with tooling arm well-suited for scouting, sample return and science exploration
• Travel range greater than 500 m
• Unaided operations on slopes up to 30 degrees
• Tethered operations on steep slopes up to 65 degrees
• Variable and modular configuration provides added flexibility for a variety of operational scenarios over rocky terrains
• Navigation system allows remote, autonomous or collaborative control mode
• Prime contractor: Engineering Services Inc.
• Contract value: $2.15 million
• Partners: Cohort Systems Inc (formerly Frontline Robotics), York University

The Mars Exploration Science Rover is one of the CSA’s new terrestrial prototypes, and is much like a robotic geologist for conducting science on the surface of the Red Planet, especially for a mission to return samples from the Red Planet for study on Earth. The solar powered six-wheeled rover is designed to operate with a robotic arm with a microscope and mini-corer on the end to drill into rocks to analyze their composition, and retrieve interesting samples for study.

• Mass: 250 kg
• Can carry up to 70 kg of science payloads
• Tele-operations enabled
• Nominal speed: 0.4 km/h
• 6 wheel-drive, 4 independent steering, flexible suspension
• Solar-powered (329 W max)
