Research in the area of autonomous mobile robots has increased over the last several years. Autonomous mobile robots are now being used in a wide variety of applications, including nuclear plant maintenance, interplanetary exploration, military missions and smart highway systems. This thesis is a survey of recent publications, 1990-1996, of wheeled autonomous mobile robots for harsh environments. Various sensing, navigation, and motion control strategies commonly used on autonomous mobile robots are compared. The integration of all three systems in a system architecture is also presented. Following a general discussion of autonomous mobile robot technology, vehicles that have entered the Unmanned Ground Robotics Competition are presented as a focused study of the application of this broad field of research.
