ABSTRACT
This project develops a wheeled, rescue robot that used in battle to find out live humans in the war fields and moves them in to the camp by managing threats. The aim of this project is to cater the need of internal and external security to the army and war fields where human security is improved and no threat to human life. This system eliminates huge losses due to terrorism and antisocial elements. The system continuously monitors the critical location and this information can be viewed and controlled through a PC in the control room with the help of a wireless cam which is attached with the canon. If the robot detects a person with light movements, it moves towards him and checks the body temperature. A live person will possess a body temperature of 37°C or near by body temperatures. The body temperature is monitored using Thermal Imaging Technique to achieve accurate results. Now if an alive human has been found by the robot it picks the person using its robotic arm and carry him to the rescue camps.The module can be controlled by the security person from a remote location also by viewing the surroundings. The image sensing has been improved by implementing MATLAB based Image Processing techniques. The Robot is self balancing, so that it can move in uneven surfaces even. The main advantage of robot is that it can be implemented in such places where human intervention is not possible. It can possess a better alternative in the case of rescue purpose, where humans can be replaced by robots so that we can ensure a secure life.
The features of robot include self rotation of body parts in 360 degrees, head movement in 180 degrees. The device catches both the audio and video signals and transmits it through the wireless media so that control station can verify it and can sense the threat if any. The canon is embedded with modules that provide thermal imaging module, which senses the human body temperature and an obstacle sensor to detect the obstacle in front of it. An ultrasonic sensor is implemented for this purpose. Ultra sonic sensor continuously generates pulses that reflect back if an obstacle comes in its field. The central processing unit receives the data and calculates the distance between the robot and object. If the distance is found to be less than the pre defined value it takes necessary steps, Initiates the relay for firing if necessary. Device also holds a laser gun by which the canon can shoot the stranger who tries to enter the field/ location with out the permission.
