A robot can be controlled by a human operator, sometimes from a great distance. But most robots are controlled by computer. An autonomous robot acts as a stand-alone system, complete with its own computer (called the controller). Insect robots work in supervision of a single controller. The term insect arises from the similarity of the system to a colony of insects, where the individuals are simple but the fleet as a whole can be sophisticated, Recently, it has sometimes been impossible for fire-fighting personnel to access the site of a fire, even as the fire causes tremendous property damage and loss of human life, due to high temperatures or the presence of explosive materials. Therefore, designing the fire extinguisher robot can overcome this problem with reduce the human injury. This project includes the specification and design for fire extinguisher robot.
