Adaptive neural control in mobile robotics: experimentation for a wheeled cart

摘要

This paper presents experimental results of an original approach to the neural network learning architecture for the control and the adaptive control of mobile robots. The basic idea is to use nonrecurrent multilayer-network and the backpropagation algorithm without desired outputs, but with a quadratic criterion which specify the control objective. To illustrate this method, we consider an experimental problem that is to control cartesian position and orientation of a nonholonomic wheeled cart. The results establish that the neural net learns online the kinematic constraints of the robot. After several online learning lessons the net is able to control the robot at any configurations in a limited cartesian space.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
