Abstract:
In this paper a robotic wheel chair is controlled by two different modes. In the present Robotic wheel chair designs there are several constraints in controlling the wheel chair and the wheel chair has constraints for people with different disabilities. In this system the robotic wheel chair is designed by two modes manual mode and automatic mode. In the manual mode the robot can be controlled manually by the user. In the automatic mode the robotic wheel chair can be controlled automatically by the controller.
Existing System:
In the present existing system the robotic wheel chair can be controlled by only one mode that is in manual mode or in automatic mode which put several constraints on the user. This reduces the flexibility of the robotic wheelchair use.
Proposed system: In the designed system the flexibility of usage of the robotic wheel chair is increased. The System is controlled by two modes. In the first mode the manual mode in which the robotic wheelchair is controlled using a keypad. In the second mode the automatic mode the robotic wheel chair is controlled by the microcontroller. In the automatic mode the wheel chair acts as a line follower robot. In which the robot follows a definite path to reach a destination. And an ultrasonic sensor is used to detect obstacles. Eye blink sensor is used to control the robot. A mode selection switch is used to transfer between two modes of usage.
