Abstract: With the increasing aging of the population in China, in order to help the elderly and the physically disabled to travel normally, this paper proposes to design a multi-functional intelligent wheelchair based on attitude algorithm and incremental PI algorithm. STM32F103ZET6 is used as the core processor for the simulated wheelchair. With attitude algorithm of gestures and gesture recognition technology of the elderly's gestures, multi-module and multi-sensor fusion realizes the gesture control of wheelchair movement and steering, automatic obstacle avoidance, real-time transmission of GPS positioning information, one button call for help, and accidental video recording. The output of incremental PI algorithm is the added value of the last output, which can make the wheelchair run smoothly. The results show that the attitude algorithm improves the recognition rate of wheelchair gesture, the incremental PI algorithm improves the smoothness of wheelchair driving, and the modular design idea meets the requirements of wheelchair safety and intelligence, which helps disabled people and elderly people with mobility disabilities to travel normally. |
