The most significant federal investment in intelligent vehicle R&D in the U.S. is being conducted by the US Department of Defense (DOD) through the Demo III autonomous scout vehicle program. Demo III is an aggressive development effort in autonomous tactical ground vehicle technology R&D. Robotics has been identified by numerous DOD studies as a key enabling technology for future military operational concepts. The Demo III program is a multiyear effort encompassing technology development and demonstration on testbed platforms, together with modeling, simulation, and experimentation directed toward optimization of operational concepts to employ this technology. The primary program focus is the advancement of capabilities for autonomous mobility through unstructured environments, concentrating on both perception and intelligent control technology. The program has developed the Experimental Unmanned vehicle (XUV), a small technology testbed vehicle. The XUV design couples multisensor perception with intelligent control to permit autonomous cross-country navigation at speeds of up to 32 kph during daylight and 16 kph during hours of darkness. The system design also encompasses onroad operations at up to 64 kph, including the capability to respond intelligently to other traffic and obstacles. When it concludes in 2002, Demo III will provide the military with both the technology and the initial experience required to develop and field the first generation of semiautonomous tactical ground vehicles for combat, combat support, and logistics applications. The Demo III program has a high potential for technology spinoffs to civilian transportation, particularly in the area of obstacle detection and intelligent machine perception. This paper includes a description of the program approach, the sensor suite, progress in the last year; and potential spinoff areas to ITS. |
