A multi-level planning and navigation system for a mobile robot: a first approach to HILARE

Abstract: This paper describes the current state of HILARE: a modular progressively-built mobile robot aimed at general robotics research. The computer organization comprises of local mini and micro processors coupled with a remote time-shared system acting as a consulting facility. A multi-level decision-making system is presented with world models, inference rules, and algorithms particular to each level. The navigation planner uses a geometric model wherein 2-space is partitioned into polygonal areas based on perceptual and/or initial information. A cost function is proposed which provides support for optimal or E-optimal path finding.

The role of navigation satellites in oil exploration

Abstract: Since the release of the Navy Navigation Satellite System (or Transit) to the public in 1967, the oil and gas exploration industry has been an active innovator and end user of this potentially highly effective navigation and positioning tool. However, many knowledgeable people outside the oil exploration community, and even some people from within the community, do not know the role played by Transit in the pursuit of increasingly difficult to find oil and gas reserves. Moreover, these same individuals are unaware of the costly operational delays in exploration activity caused by the present poor orbital coverage in the Transit System. This paper attempts to call attention to the oil and gas exploration communities' requirements for navigation and positioning and to the active role played by the Transit Satellite System. The possible uses of future navigation satellite systems (such as GPS) are also explored. Most important, this paper puts forth the plight of the civil user of the present day Transit system and the civil user's similar predicament if commercial use of GPS is available only in the coarse code mode.

Mobile robots for industrial use

Abstract: The free roving robot in the form of a computer controlled industrial truck is now technically possible. The use of small on‐board computers and navigation aids frees the robot from dependence on fixed route marking. Conventional vehicles such as fork lift trucks may be modified for autonomous or semi‐autonomous control.

Position-Location/Navigation Systems Overview for Military Land Vehicles

Abstract: : Position-location/navigation systems are overviewed tutorially for possible application to military land vehicles. The overview includes position- location by celestial navigation, rho/theta systems, hyperbolic systems, radar, inertial systems and satellite systems. Potential advantages and disadvantages of applying various position-location systems to military land vehicles are suggested.
