Abstract
Upcoming missions to the surface of Mars will use mobilerobots to traverse long distances from the landing site. Toprepare for these missions, the prototype rover, Rocky 7,has been tested in desert field trials conducted with a teamof planetary scientists. While several new capabilities havebeen demonstrated, foremost among these was sun-sensorbased traversal of natural terrain totaling a distance of onekilometer. This paper describes navigation results obtainedin the field tests, where ...
