During the development of the Lunar Exploration Light Rover, BRP, a subcontractor of the prime subcontractor, MacDonald, Dettwiler and Associates Ltd., created the SL-Commander. This all-terrain vehicle is an electric version of BRP's commercially available BRP Commander. It is fully automated and can be remotely operated to drive itself at a maximum speed of 40kph (24.85mph). The SL-Commander weighs 1,100kg (2,425 pounds) and can carry a payload of 200kg (440.9 pounds). (Source: Canadian Space Agency)
