- Abstract:
-
In order to solve the poor effects of traditional behaviorbased path planning of intelligent wheelchairs in an outdoor unstructured environment, a new path planning method was proposed in this paper. The new algorithm uses fuzzy logic to design basic control behavior, and on this basis applies a neural network to design behavior coordination by combining a large amount of practical experience. The improved algorithm can combine arbitration mechanisms with fusion mechanisms successfully; it absorbs the major advantage of these two original algorithms and improves response speed of the system while enhancing the control accuracy significantly. On the other hand, the method can identify trap area and control the wheelchair escape from the trap by changing the behavior weights independently, therefore displaying strong artificial intelligence characteristics. The simulation and real experimental results verify that the algorithm is capable of advanced intelligence and can be implemented easily. Additionally, it can be used in an outdoor unstructured environment for robot path planning.
