2. INTRODUCTION
 Gesture Controlled Robot is a robot which can be
controlled by simple gestures.
 The user just needs to wear a gesture device which
includes a sensor.
 The sensor will record the movement of hand in a
specific direction which will result in the movement
of the robot in the respective direction.
 The robot and the Gesture device are connected
wirelessly via radio waves.
 The wireless communication enables the user to
interact with the robot in a more friendly way.

3. COMPONENTS
 Accelerometer
 Arduino Nano
 Encoder
 Transmitter
 Receiver
 Decoder
 Motor Driver IC
 DC Geared Motor
 9V Battery
 Voltage Regulator IC

4. BLOCK DIAGRAM
 TRANSMITTER
 RECEIVER

5. ACCELEROMETER
 An Accelerometer is an electromechanical device
which sence movement
 ADXL 335 accelerometer is used here, which can
sence X,Y,Z direction. Here only X & Y are used

6. ARDUINO NANO
 Arduino Nano is the microcontroller used
 The Arduino Nano is a small, complete, and
breadboard-friendly board based on the
ATmega328P

7. ENCODER IC
 An encoder is a device, that converts information
from one format to another.
 Here we are using encoder for converting parallel
data into serial data.
 The HT12E is an 4bit encoder which encode the
input data applied on it .It is mainly used in
interfacing RF and infrared circuits.

8. RF TRANSMITTER
 The word RF stands for “Radio Frequency”
 The radio frequency has ability to cross obstacles
plus it provides good coverage of 30 meters
 Here a 433Mhz RF transmitter/receiver module is
used

9. RF RECEIVER
 The transmitted data is received by an RF receiver
operating at the same frequency as that of the
transmitter.
 Both the transmitter and receiver works on 5v DC

10. DECODER IC
 A decoder is a device which does the reverse
operation of an encoder.
 Original information can be retrieved.
 HT12D converts that serial data into parallel.

11. MOTOR DRIVER IC
 It is also known as H-Bridge or Actuator IC
 L293D is the driver IC used
 It’s quadruple high-current half-H drivers
 It can be used to control two DC motors in same or
different direction

12. DC GEARED MOTOR
 A geared DC Motor has a gear assembly devoted
to the motor
 This concept of reducing the speed with the help of
gears and increasing the torque is known as gear
reduction
 Here 2 DC geared motor of 100rpm is used, which
is run by L239D IC

17. APPLICATONS
 Through the use of gesture recognition, remote
control with the wave of a hand of various devices
is possible.
 Gesture controlling is very helpful for handicapped
and physically disabled people to achieve certain
tasks, such as driving a vehicle.
 Gestures can be used to control interactions for
entertainment purposes such as gaming to make
the game player's experience more interactive or
immersive.
