Abstract : For over a decade, the National Bureau of Standards has been developing a control system to help facilitate the flexibility of machines and robots on the factory floor and to develop a true 'system' - an organized integrated whole made up of diverse but interrelated and interdependent parts. They established a set of rules by which to interface machines and computers in a work environment. The theory of control of this system is called the Real-Time Control System ( RCS ). The RCS is described as a system where high-level goals are decomposed through a succession of levels, each producing strings of simpler commands to the next lower level. The RCS system is now being applied to a real-life situation for the US Navy - the control of an unmanned underwater submarine to be used for deploying underwater mines, seeking and destroying enemy targets, and searching an area for charting. This thesis covers the application of the RCS to the search of an area by one or two of the underwater autonomous vehicles ( AUV ). This thesis addresses issues concerned with the valid techniques to be used in a two AUV search and the algorithms to be generated by an expert system that control the movements of the AUVs. It describes seven search techniques adapted from military techniques applied to foot soldiers.
