This document describes a wheelchair designed for physically disabled people that can be controlled through voice commands, ultrasonic sensors, and infrared sensors. The wheelchair has three driving modes - manual control using a joystick, voice control using various voice commands to navigate, and autonomous control where the wheelchair follows walls and avoids obstacles on its own. The electronic system uses feedback control of the motors, speech recognition, ultrasonic and infrared sensors, and a memory board. The multi-sensor system allows the wheelchair to safely detect obstacles and changes in floor level.
