Development of Electric Wheelchair for Smart Navigation and Health Monitoring System

This paper presents framework of smart wheelchair for differently abled people by incorporating many facilities in a single wheelchair at low cost. A prototype of smart electronic wheelchair is developed to help the individual move freely without any external assistance. The wheelchair can also be converted into a stretcher. The system will monitor the vital health parameters such as pulse rate, heart rate, temperature and ECG of the disabled person and the information is stored in cloud (Thing Speak). An alert SMS will be sent to the care taker in the abnormal health conditions. The proposed system is developed using raspberry pi single chip-computer, it is implemented using Python serial data communication, PWM and android application
