This article presents a robust approach to navigating at high-speed across desert terrain. A central theme of this approach is the combination of simple ideas and components to build a capable and robust system. A pair of robots were developed which completed a 212 kilometer Grand Challenge desert race in approximately seven hours. A path-centric navigation system uses a combination of LIDAR and RADAR...
Boss is an autonomous vehicle that uses on-board sensors (GPS, lasers, radars, and cameras) to track other vehicles, detect static obstacles and localize itself relative to a road model. A three-layer planning system combines mission, behavioral and motion planning to drive in urban environments. The mission planning layer considers which street to take to achieve a mission goal. The behavioral layer...
The use of nondispersive infrared (NDIR) detection technology as a basis for a hazardous area classification is described. Methods for identifying fugitive emission leaks using NDIR technology, quantifying leak data, and applying the results to document the basis for a hazardous area classification are presented. Limitations associated with the technology are also defined. A case history of a gas...
