Jayesh K. Kokate, A. M. Agarkar

Abstract: This paper introduces the wheel chair which is controlled by voice commands from the handicapped person. Voice commands are received by the android mobile and converted into the text and provided to the Microcontroller PIC 16F877 for controlling the movement of wheel chair. The input command from the android mobile is transferred to the Microcontroller with the help of Bluetooth module wirelessly. Two DC motors are used to control the movement of wheel chair. These motors are connected to the back wheels of wheel chair with the help of a gear mechanism. Battery is used to provide the power to the DC motors. Two double pole Relays are used, which connects the battery to the DC motors and the operation of relay is controlled by the microcontroller. Two IR sections, forward and backward are used to detect the obstacle in the path of wheel chair. The block diagram, hardware used and performance analysis of wheel chair is presented in this paper.
