AbstractThe Smart Wheel chair system proposed in this paper helps to physically disable people or adulthood people to move around without others help. Normal wheelchairs are manually operated and heavy to move. It makes suffered people to depend on others. These wheelchairs that are equipped with sensors and a data processing unit constitute a special class of wheeled mobile robots, termed smart wheelchairs in general literature overviews. n the existing system, the wheel chair movement is controlled by joystick and buttons are used to start and stop the wheel. This is difficult to handle the differently able person to press the button. In the proposed system, the physically disabled person can control their wheel by manual. MPU6050 sensor is used for gesture symbol. In manual mode MPU6050 sensor and accelerometer is used to control the direction of the wheel of the motor. The proposed system contributes to the self dependency of differently able and older person. The robot will be access both manual and automatic mode. Blood oxygen sensors monitor the oxygen level of blood in patient body, blood pressure sensor monitor the patient heart rate parameter and the temperature sensor is used to calculate the body temperature, these sensor are monitor by the microcontroller and the microcontroller collect the data are sending to mobile phone via Bluetooth module.
