This document provides an overview of an accelerometer-based gesture control robot project. It introduces the motivation to control devices through gestures instead of buttons. It describes the main components used: an accelerometer sensor to detect hand motions, a microcontroller development board with an ATmega32 chip, and RF modules for wireless signal transmission and reception. The logic used involves transmitting gesture motion signals from the accelerometer to control the robot's movement via a motor driver circuit. Potential applications are in hazardous environments like nuclear plants, military uses, and for human convenience. Further improvements could enhance the accelerometer, use more accurate wireless protocols like ZigBee, and add multiple motion controls.

2. INTRODUCTION
• A Gesture Controlled robot is a kind of robot which can be
controlled by your hand gestures not by old buttons.
• We just need to wear a small transmitting device in your
hand which included an acceleration meter.
• This will transmit an appropriate command to the robot so
that it can do whatever we want.

3. MOTIVATION FOR THE PROJECT
Most of the devices used are controlled through remotes ,joysticks
or the pushbuttons.
why???
why not they can be controlled by human gestures only........just
moving our hand we can get a desired results
So here is our simple approach where we are controlling a robot
wirelessly through human gestures using a sensor called
accelerometer.

4. COMPONENTS USED
1. Accelerometer:
•An accelerometer is an electromechanical device that
measures acceleration forces.
•These forces may be static, like the constant force of
gravity pulling at your feet, or they could be dynamic -
caused by moving or vibrating the accelerometer.

5. 2. Development board with Atmega32
microcontroller:
• We are using a two self made development board with Atmega32
microcontroller one for the transmission and another for receiving.
•It is a 8 bit controller and has 32KB of flash memory.
•The board also consists of motor driver circuit with L293D IC.

6. 3. RF MODULE-
We are using two pairs RF modules one for transmitting the signal and other
for receiving the signal.
Features:
• 2.4 GHz Carrier Frequency
• 255 possible channels
• RS232 UART interface with variable baud Rate
• Standard configuration baud rate 9600
• Power LED indicator
• Input Supply 5V to 12V

9. SETUP USED

10. APPLICATIONS
• Nuclear Power Plants: where human interference is quite difficult .
• Military Purposes : a wireless gesture robot can interfaced with other
sensors to know the position of the enemies
• Human Comforts: human comforts can be enhanced by the use of
gesture technique

11. IMPROVEMENTS
• The accelerometer consists of noise which can be improved
by high pass filtering or using kalman filtering technique for
better results
• Instead for RF wireless module we can use ZigBee wireless
protocol which provides better accuracy and better range than
RF modules.
• Multiple motions can be controlled using same accelerometer.
