Abstract

ENGLISH ABSTRACT: The Centre for Robotics at the University of Stellenbosch set itself the objective of building a fairly complex manufactu.ring ceH, including .'.11 unskilled human as a system componenL As a precursor to this effort we constmcted a simple cell requiring both supervision of a robot and supenision of a human using a Micro-Prolog knowledge system to do so. l1tis was successfully done but at the costar low execution speed and difficulty in integrating machine code instructions for machine control interfacing with the largely consultation orientated softv,are which rendered the approach unsuitable fortbe more complex cell. MiCroExpert "..as used for this new effort but we a1sa tried Turbo-Prolog 10 mimick the inference engine of the former software. This experience made us decide 10 trade the higher speed achieved by Turbo-Prolog for the much more rapid knowledge base development in MicroExpen. To do so it was necess::.uy to bulld a special frame data sLrUtTille and to enhance. Micro-Expert for supervising such manufactlrring cells.
