QUADRIPLEGIC AMBULATING ADDENDUM
Keywords:DC Motor, MEMS Sensor, Quadriplegics, ambulation.
The exigent problem faced by the paralyzed people is their independent ambulation. They need an external help to perform their daily activities. The person affected by Hemorrhagic disease, a type of stroke which leads to Quadriplegia. These kinds of patients cannot access their limbs where only head tilting is possible. Assist devices used by quadriplegic patients are very complicated, rarely available and expensive. The main objective of this project is to propose an idea for an automated system for the disabled people. The ambulating chair will work based on the head movement of the user. The recognized gestures are used as an input to the controller so that the assist device can be controlled according to the user intension. The wheel chair system is divided into two main units: MEMS Sensor which consists of accelerometer that detects direction of motion and Controller. The MEMS sensor senses the change in direction of head and accordingly the signal is given to microcontroller. Depending on the direction of the Acceleration, microcontroller controls the wheel chair directions like LEFT, RIGHT, FRONT, and BACK with the aid of DC motors.
