In this thesis, an automatic charging method for intelligent wheelchair is developed. For controlling of wheelchair, based on the primal hardware architecture, the Raspberry Pi embedded platform is adopted to control the voltage of the wheelchair. By examining the automatic charging of wheelchair, the color mask and connected component labeling methods are adopted to find the center of object. Utilizing the relation between the wheelchair position and the target center of object, the wheelchair can move to the charging position automatically. Moreover, the fuzzy controller is adopted to control the wheelchair for adjusting the angle and speed of wheelchair more precisely. The experiment results show that the developed system and the proposed control method are valid and feasibility.
