Abstract
In this paper, a hybrid intelligent method including fuzzy inference and ne ural network is presented for real-time self-reaction of a mobile robot in unknown environments. A neural network with fuzzy inference (fuzzy neural n etwork, FNN) presented can effectively improve the learning speed of the ne ural network. The method can be used to control a mobile robot based on the present motion situations of the robot in real-time, these situations incl ude the distances in different directions between the obstacles and the rob ot provided by ultrasonic sensors. the target orientation sensed by a simpl e optical range-finder and the movement direction of the robot. Simulation results showed that the above method can quickly map the fuzzy relationship between the inputs and the output of the control system of the mobile robo t. (C) 2001 Elsevier Science Ltd.
