PROBLEM STATEMENT
The main idea behind taking up such an initiative is to create robot that is small yet effective enough that would sneak into disaster conditions like Earthquake or Bomb blast, where we have to identify live human beings as quickly as possible to save life.
ABSTRACT
This project is all about making a robot, which navigates around the disaster areas and tries to find the humans who need help. After finding the humans it transmits the location to the PC. The second part is the receiver and the PC. The bot will be controlled using RF remote control.
The receiver receives the signals sent by sensor on the robot and feeds it to the PC.
The robot can easily navigate through rough terrain due to its rugged design.
The robot uses two methods to detect a human.
One is using the IR radiation emerging from the live humans. All PIR sensors detect changes in infra-red radiation, in the form of heat emitted by number of bodies including live humans. When a person or other heat source enters in sensors detecting zone, the level of infra-red radiation in that zone increases& detection is achieved.
The on board camera will be used for navigation and taking images of the victims.
SERVOMOTORS
A servomotor is a rotor actuator that allows for precise control of angular position.
They consist of a motor coupled to a sensor for position feedback, through a reduction gearbox. They also require a relatively sophisticated controller.
It is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is some signal, either analogue or digital, representing the position commanded for the output shaft.
The motor is paired with some type of encoder to provide position and speed feedback.
