Gesture Based Wheel chair

Mostly Physically Handy-capped people always face trouble in moving from one place to another place. Through this project, you are going to create a unique wheelchair which can be controlled with the Wrist movements using an accelerometer.

You will need an Arduino Uno board for interfacing microcontroller with the Accelerometer. The accelerometer will be attached to the glove. The accelerometer will detect the movement of the Wrist with respect to two axes (X and Y).

You will program the microcontroller in such a way that say whenever you bend your Wrist, the accelerometer will give new coordinates (Shifted Coordinates in X-Y Plane). The new coordinates will be compared with default coordinates and Based on this comparison, your microcontroller will make your wheelchair to move into specified direction.

Project Description:

1. Accelerometer: An accelerometer is a device that measures proper acceleration. Proper acceleration, being the acceleration (or rate of change of velocity) of a body in its own instantaneous rest frame, is not the same as coordinate acceleration, being the acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards of g (9.81 m/s2). By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero.
   • Capacitive
   • Piezoelectric
   • Piezoresistive
   • Hall Effect
   • Magnetoresistive
   • Heat Transfer
   The accelerometer which you are going to use is a capacitive type 3-axis Accelerometer Sensor. It measures acceleration within minimum full-scale range of ±3g.( but we use only two axes here)
2. Arduino/Genuino Uno: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
3. DC motors: These motors works with DC power as name indicates itself. So these motors will convert the DC Electric power in Rotating Mechanical Power.
4. Motor Driver: Generally the Arduino board is not capable of providing the required amount of current for running the motors. So we use a device called Motor Driver which will provide sufficient current for driving the motors.

Project Implementation:

1. Attach those Accelerometer to glove and wear the glove in such a way that when you move your wrist, the initial position of the accelerometer should change.
2. Interface the Accelerometer and DC motors with the Arduino board.
3. Upload the code.
4. Test the chair by moving your wrist.

Software requirements:

1. Arduino IDE : You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
2. Thingspeak : Also, you need to create an account in the ThinkSpeak IoT platform to integrate the system onto the cloud and store the data online
