Intelligent semi-autonomous vehicles in materials handling

An increase in functionality of semi-autonomous vehicles (SAV) through the implementation of intelligent distributed control and smart sensing techniq ues is presented. In combination with a modular design approach, this facil itates system modification and improvement, combined with faster customisat ion of the platform. A distributed and reactive behavioural control archite cture is used to realise local autonomous navigation capabilities; improved operator interaction; self protection and safer operation. A virtual engin eering environment based on a computer-aided-graphics platform is used (1) for modelling the vehicle and the environment in which it can operate; (2) developing preemptive learning and training of responses/behaviours, and (3 ) for evaluation of vehicle functionality as part of an integrated material s handling system.
