Abstract

The invention provides an intelligent wheelchair outdoor navigation method based on coordinated control. The method is characterized by acquiring external environment information by a GPS (global positioning system) and ultrasonic sensors, firstly adopting a control method based on behaviors to coordinate with a fuzzy logic algorithm to design behavior modules with different functions, secondly adopting a neural network algorithm to design a behavior coordination controller, and realizing the autonomous navigation function with higher intelligence through the coordinated control of the behavior modules. The method has the advantages that the cost of the outdoor navigation system can be lowered; and the real-time property and the robustness of the system can be improved.

Description

technical field

[0001] The invention relates to the field of automation, in particular to a navigation method. Background technique

[0002] In general, the mobility and responsiveness of the elderly and disabled people are lower than that of ordinary people, so assistive tools designed for them should not only have good mobility, but also have the ability to think independently and communicate with users easily Ability. As an intelligent electric wheelchair, the smart wheelchair can not only be driven by a motor, but also has the intelligence of a high-end mobile robot. It has a good human-machine interface and can realize autonomous control. It is used as an auxiliary tool for the elderly and the disabled. best choice.

[0003] There are still some problems for ordinary smart wheelchairs to be practical in outdoor environments: the navigation effect is not good in unknown environments; the navigation algorithm is not real-time enough, and it is difficult to adapt to the ...
