Gesture Controlled Walking Robot

Robotics is one of the trending topics today. There are many ways in which we can control the robot. One of the top technology of controlling Robot is using Human Gestures. Through this project you are going to create Walking Robot which can be controlled using your own Hand Gestures.

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 axis (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 you’re the robot walking 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 centre of the Earth at a rate of about 9.81 m/s2) will measure zero.
   • Capacitive
   • Piezoelectric
   • Piezoresistive
   • Hall Effect
   • Magnetoresisitive
   • Heat Transfer
   The accelerometer which you are going to use is a capacitive type 3-axis Accelerometer Sensor.It measures acceleration with in minimum full-scale range of ±3g.( but we use only two axis here)
2. Arduino 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. Servo Motors: A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position
4. Motor Driver: Generally the Arduino board is not capable of providing 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 Servo motors with the Arduino board
3. Power the Robot and upload the code
4. Test the Walking Robot by moving your wrist
