This paper describes the “Design and Implementation of Tongue Motion Controlled Wheelchair”. Most serious accidents and injuries often end with various motorist disabilities usually resulting in a limited control of the muscles of various body parts and in some worst case scenarios even the whole body. Tongue driven system is a new wireless assistive technology for persons severely disabled due to spinal cord injuries, quadriplegia or repetitive strain injuries (RSI). It translates the user’s intensions into control commands by detecting and classifying their voluntary tongue movements. Tongue driven system consists of an array of hall effect magnetic sensors and permanent magnet which is held on tongue using tissues adhesive and tongue piercing. An array of magnetic sensor is mounted on the headset outside the mouth. The RF module is used for wireless technology and AT mega328 is used as a controller. The sensor’s output is wirelessly transmitted to the microcontroller and it will process the signal to control the movement of power wheelchair. Two DC motors are used to drive the wheelchair. This technology provides faster advanced smoother and more convenient control.
