– The Cool Robot is a four-wheel-drive, solar-powered autonomous vehicle designed to support summertime science campaigns in Antarctica and Greenland. We deployed the robot at Summit Camp, Greenland, during 2005 to validate its power budget and to assess its unique control system that matches solar power input with power demand as the robot drives over(More)
This paper describes the design and fabrication of a low cost, solar powered mobile robot to support a variety of scientific missions on the Antarctic plateau during the austral summer. Key to the overall design is maintaining a lightweight vehicle by using a high strength and stiffness honeycomb-fiberglass composite chassis, custom wheels and drivetrain(More)
Many approaches to the formation control problem for multi-robot systems have been proposed. In distributed consensus algorithm methods [1-3], and leader-follower structures [4] the robots are explicitly assigned positions within the desired formation. By contrast, artificial potential function (APF) control [5-9] generally does not specify a formation(More)
— This paper describes the design and fabrication of a low cost, battery-powered mobile robot for ground penetrating radar surveys in support of Polar science and logistics. Key features of the design include lightweight construction for low resistance and high energy efficiency in deformable terrain; a passive, articulated chassis for high mobility; and(More)
