Generally, robots are programmed to perform specific tasks which humans cannot. To increase the use of robots where conditions are not certain such as fire fighting or rescue operations, robots can be made which follow the instruction of human operator and perform the task. In this way decisions are taken according to the working conditions by the operator and the task is performed by the robots. Thus, we can use these robots to perform those tasks that maybe harmful for humans. This paper describes about the gesture control robot which can be controlled by your normal hand gesture. It consists of mainly two parts, one is transmitter part and another is receiver part. The transmitter will transmit the signal according to the position of accelerometer and your hand gesture and the receiver will receive the signal and make the robot move in respective direction. Here, the program is designed by using Arduino IDE

CHAPTER ONE
1.0                                                        INTRODUCTION
In recent years, robotics is a current emerging technology in the field of science. A number of universities in the world are developing new things in this field. Robotics is the new booming field, which will be of great use to society in the coming years.
Though robots can be a replacement to humans, they still need to be controlled by humans itself. Robots can be wired or wireless, both having a controller device.

Both have pros and cons associated with them. Beyond controlling the robotic system through physical devices, recent method of gesture control has become very popular. The main purpose of using gestures is that it provides a more natural way of controlling and provides a rich and intuitive form of interaction with the robotic system. These days many types of wireless robots are being developed and are put to varied applications and uses. Human hand gestures are natural and with the help of wireless communication, it is easier to interact with the robot in a friendly way. The robot moves depending on the gesture made by your hand and from a distance. The objective of this paper is to build a gesture control robot using Arduino, accelerometer, RF transmitter and receiver module. The Arduino Uno microcontroller reads the analog output values i.e., x-axis and y-axis values of the accelerometer and converts that analog value to respective digital value. The digital values are processed by the Arduino Uno microcontroller and according to the tilt of the accelerometer sensor mounted on hand, it sends the commands to the RF transmitter which is received by the transmitter and is processed at the receiver end which drives the motor to a particular direction.
The robot moves forward, backward, right and left when we tilt our palm to forward, backward, right and left respectively. The robot stops when it is parallel to the ground.

1.2                                             OBJECTIVE OF THE PROJECT
The objective of this work is to design a robotic device 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.
1.3                                                  PROJECT MOTIVATION
Our motivation to work on this project came from a disabled person who was driving his wheel chair by hand with quite a lot of difficulty. So we wanted to make a device which would help such people drive their chairs without even having the need to touch the wheels of their chairs
1.4                                                 SCOPE OF THE PROJECT
In many application of controlling robotic gadget it  becomes quite hard and complicated when there comes the part of controlling it with remote or many different switches.Mostly in military application, industrial robotics, construction vehicles in civil side, medical application for surgery. In this field it is quite complicated to control the robot or particular machine with remote or switches, sometime the operator may get confused in the switches and button itself, so a new concept is introduced to control the machine with the movement of hand which will simultaneously control the movement of robot.

1.5                                          APPLICATION OF THE PROJECT

• Wireless controlled robots are very useful in many applications like remote surveillance, military etc.
• Hand gesture controlled robot can be used by physically challenged in wheelchairs.
• Hand gesture controlled industrial grade robotic arms can be developed.

1.6                                         SIGNIFICANCE OF THE PROJECT
It is easy to design and manufacture as all the components are easily available. 0 It is portable and hence can be placed anywhere. It has low cost of manufacturing. It can be reprogrammed if any modification is required. Due to wireless communication data rate is faster.  Wireless makes ease of operation. No need of lengthy wires. Power consumption is less.

1.7                                           LIMITATION OF THE PROJECT

• If power supply fails system won’t work
• Failure of device/components may have dire consequences, fatal accidents can occur.

1.8                                 FUTURE DEVELOPMENTS
We can also add an obstacle detection sensor in the wheel chair. Increase power capacity.

1.9                                        PROJECT WORK ORGANISATION
