A Novel Economical Embedded Multi-mode Intelligent Control System for Powered Wheelchair

In order to assist different kinds of disabled persons and senior citizens, to lower the cost and improve the effectiveness and convenience of human-machine interaction, a novel economical embedded multi-mode intelligent control system for powered wheelchair is developed. The system is based on a high-performance 16-bit compact single chip system. It has “Manual”, “Speech”, “Vision”, and “Autonomous” four modes that are fulfilled by four modules. The mode and the corresponding module can be customized according to the needs of different users and situations and that makes a further lower cost. In addition, fusion of multi-mode and other security measures are discussed. The hardware, software, control mechanism, and some experimental results are elaborated in the paper.
