Design of a Robotic Firefighting Machine

Abstract

The destruction of property and the environment by fires has necessitated the need for the design of an autonomous firefighting robot. Extreme cases of uncontrolled fires result in injury or even death. This paper presents a design for a firefighting robot with two degrees of freedom. The robotic arm will be able to direct a jet of water within a radius of 15 m. The ability of the machine to manoeuvre on its own, through the use of proximity sensors and flame finders reduce the risk of exposure to fire and smoke of the operator. The device is powered by two DC 40 Ah Lithium Ion batteries. At USD$3,455 initial value, the machine is estimated to depreciate to a value of USD$2,277.13 after five years, at a depreciation rate of 8%. The cost benefit analysis shows that the implementation of such a project is justifiable since having such a machine reduces the risk of losing properties and other valuables to fire. Despite the undisputed importance of fire, it can also be dangerous and costly if not handled well. Unwanted fires can result in heavy losses including properties and important documents. They can also cause injuries or even death. The use of an automatic machine (robot) to fight fire ensures less risk to firefighters at the same time increasing efficiency in putting out the fire. The use of robotics and control enhances accuracy and ease of operation of the machine. Careful design of each component guarantees fulfilment of the aim, which is putting out fire, with high efficiency and effectiveness. The cost of the machine is easily overshadowed by the privileges assumed due to its manufacture. The production of this machine thus ensures reduced financial losses and increased human safety.
