Assistive technology, Emergency alert system, Health monitoring, Microcontroller, Smart wheelchairAbstract
Assistance in mobility and health monitoring is vital for those with severe physical disabilities and elderly persons who are not able to operate normal wheelchairs on their own. In recent times, various smart wheelchairs have been proposed using various technologies such as voice control, obstacle sensing, and remote monitoring to provide assistance to such persons. Most of these wheelchairs are focused on mobility and lack health monitoring and emergency assistance. This paper proposes a smart audio-controlled wheelchair with health monitoring and an emergency alert system. In this proposed work, a smart audio-controlled wheelchair is implemented using a Raspberry Pi Pico 2W microcontroller, HC-SR04, MAX30102, OLED Screen, Neo-6M GPS module, and a Wi-Fi Bluetooth module. The proposed wheelchair is controlled using voice commands such as forward, backwards, left, right, and stop using a Bluetooth interface. The proposed work provides a cost-effective and efficient solution to provide mobility assistance, health monitoring and emergency assistance.
