Human-machine interface can be considered as an essential element in robotic wheelchair control mode. The purpose of this project is to examine the functionality and efficiency of the manual control mode with the implementation of low cost RF Transmitter and Receiver modules for wireless transmission. A User's Controller Panel as well as a model of robotic wheelchair has been designed and developed to provide the testing of robotic wheelchair locomotion control via wireless data transfer. By using C programming algorithm, PIC16F877 has been used as the Microcontroller unit for robotic wheelchair while PIC16F88 as the Microcontroller unit for User's controller panel. Finally the proposed method on the implementation of wireless data transfer as well as the experimental setup also has been discussed. The results prove that low cost RF modules have the feasibility to be used for simple-one way wireless data transfer with the capability of transmitting several basic instructions to the robotic wheelchair.
