CubeRover is a class of planetary rover with a standardized modular format meant to accelerate the pace of space exploration. The idea is equivalent to that of the successful CubeSat format, with standardized off-the-shelf components and architecture to assemble small units that will be all compatible, modular, and inexpensive.[1]
The rover class concept is being developed by Astrobotic Technology in partnership with Carnegie Mellon University, and it is partly funded by NASA awards.[1] A Carnegie Mellon University initiative - completely independent of NASA awards - developed Iris, the first flightworthy cuberover. Its 2022 lunar mission will make CMU the first university in the world, and the first American entity, to successfully develop and pilot a lunar rover.[2]
The idea is to create a practical modular concept similar that used for CubeSats and apply it to rovers, effectively creating a new standardized architecture of small modular planetary rovers with compatible parts, systems, and even instruments so that each mission can be easily tailored to its objectives.[1][3][4] The rovers are expendable and do not use solar arrays for electrical power, depending solely on non-rechargeable batteries. This allows it to be lighter, have a larger cooling radiator panel for electronics, and have a simpler avionics design.[5]
The CubeRover program intends that standardizing small rover design with a common architecture will open access to planetary bodies for companies, governments, and universities around the world at a low cost, while increasing functionality, just as the CubeSat has in Earth orbit.[3] This would motivate other members of the space exploration community to develop new systems and instruments that are all compatible with the CubeRover's architecture.[1][3]

In May 2017 Astrobotic Technology, in partnership with Carnegie Mellon University, were selected by NASA's Small Business Innovation Research (SBIR) to receive a $125,000 award[11] to develop a small lunar rover architecture capable of performing small-scale science and exploration on the Moon and other planetary surfaces. During Phase I, the team built a 2-kg rover and performed engineering studies to determine the architecture of a novel chassis, power, computing systems, software and navigation techniques.
In March 2018, the team was awarded funds to move on to Phase II,[1][3] and under this agreement, Astrobotic and CMU were to produce a flight-ready rover with a mass of approximately 2 kg (4.4 lb).
In future missions, CubeRovers may be designed to take advantage of lander-based systems to shelter for the cold lunar night, that lasts for 14 Earth days.[3] Similarly, future larger CubeRovers may be able to incorporate thermal insulation and systems qualified for ultra-low temperatures.[3]
CMU students developed the first flightworthy cuberover, Iris. Iris will fly to the Moon on Astrobotic's Peregrine lander[12] in 2022.
