1. ABSTRACT:

Now a day’s war fare became hi-tech new technologies are introduced into military for both defeating purpose directly and supporting purpose indirectly. In this manner we have also developing a project called “COLOR TRACKING ROBOT”. The concentrated problem was an average military soldier has to carry atleast 50kgs of materials like guns, amount, granites and so. To reduce weight of the soldier will give time and efforts to him to more concentrate on enemy in war. To do that in our project we are having a camera to detect the persons by his uniform and remaining process will be done by a computer in a robot that observes position of a soldier and his movement continuously in the field and give commands to robot microcontroller to follow as per his movements. Then a soldier can drop his entry day load on robot make himself free. If he wants he can grab.

This work describes an autonomous robot for following the soldier in the war field using image processing. The proposed system uses an ultrasonic sensor in order to detect the existence of humans and also obstacles and a low cost camera in order to acquire a video of the scene as needed. Additional, we are using a buzzer for the security of the robot if lost. Having detected a sign of an obstacle, the ultrasonic sensor triggers the camera to show live scene. The video is then displayed on the screen. This approach requires a relatively small number of data to be acquired and processed during the operation. This way, the real-time cost of processing and data transmission is considerably reduced. This system has the potential to achieve high performance in carrying the materials in the war field following the soldier quickly and cost-effectively. The detection depending on a number of factors such as the body position and the light intensity of the scene. Results show that the system provides an efficient way to track and follow human being. The aim of this article is to improve the human following robot by using the image processing as a tool for good efficiency and obstacle avoidance.GSM is used for sending the message and GPS is used to finding the position of the robot.

b. Ultrasonic sensor: The aim of this project is the robot has to follow human. This is an easy task especially in the horizontal plane. To avoid the obstacles in the path of the robot we are using the Ultra sonic sensor which avoid the obstacles and make the robot to go in the correct path.(figure1)

c. DC motor: Motors take electrical energy and produce mechanical energy. Electric motors are used to power hundreds of devices we use in everyday life. Motors come in various sizes. Huge motors that can take loads of 1000’s of Horsepower are typically used in the industry. Some examples of large motor applications include elevators, electric trains, hoists, and heavy metal rolling mills. Examples of small motor applications include motors used in automobiles, robots, hand power tools and food blenders. DC motor is used here to rotate the wheels of the robot.

The above figure represent the DC motor.

d. DC motor driver: In order to control the position of a DC motor, we must be able to change the current direction to the motor. This can be accomplished by using DC motor driver. If transistors 1 Q and 3 Q are turned on, and 2 Q and 4 Q are off, current will flow through the motor in the direction shown and the motor will rotate in one direction. If 2 Q and 4 Q are on, and 1 Q and 3 Q are off, the motor will rotate in the other direction. By using these we can run the DC motor in any direction.

e.Buzzer: A buzzer is an audio signaling device which may be mechanical, electromechanical or piezoelectric. Typical uses of buzzers and beepers include alarm devices, timers and conformation of user input such as mouse click or keystroke. These are used for the security of the robot if any change in the pixel then the sound is produced.

The above figure represents the Buzzer.

f. GSM and GPS: GSM is used for sending the message.GPS is used to finding the position of the robot.

The above figure represents the GSM and GPS.

g. Personal computer and Webcam: Webcam or wireless camera is employed because it

captures the analog information and displays it in PC. This camera plays a key role capturing the

data. We are going to use an personal computer to analyze the pixels of the image and give the

command to the microcontroller.

4. PROCEDURE AND METHODOLOGY:

The goal of this project is to provide a low cost color tracking robot. Though, the existing Urban Search and Rescue Robots are equipped with various sensors, but the problem with them is the cost. The sensors used in the development of this project are easily available and cost effective. In this paper, a new method for following humans using simulated autonomous robot using image processing is proposed. The robot uses two levels of sensing in order to achieve higher cost-effectiveness in the detecting process in terms of the actual cost of equipment, the processing cost, and the power cost. The first level image is captured by the webcam of computer and it is analyzed by using processing software and there a color is fixed for following the human by the robot. The second level is an ultrasonic sensor that is used as the primary sensor in order to avoid the obstacles in the path.. The robot is equipped with a simple buzzer

Since the system developed is a low cost system therefore it has a wide future scope. Though many systems with a wide range of sensors have been developed, but there are many problems faced by them such as cost, size, environment difficulties etc.GSM and GPS is used to find the location of the robot.

The future work would be improved by using the IR cameras for better accuracy and precision and also and neural human algorithm is used for face detection and body shape detection.

5. APPLICATIONS:

1. In military applications for carrying the guns, granites and food material. 2. These are used in super markets for carrying the items without any human interference.3. These are used for the aged walking.

6. FUTURE EXTENSIONS:

1. We can use face recognisition for better identification.2. We can use also set body shape for better identification.3. By adding IR cameras we can have accuracy and precision.
