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. (C) 1999 Elsevier Science Ltd. All rights reserved.
