The concept of engineering robots has become increasingly popular in last decades. Industrial and commercial businesses that can afford the cost of robotic systems, have introduced them into their manufacturing processes. These technologies are not popular at the consumer level, since it can become costly. In this thesis a fire fighting robot is designed and compared with others that have been created. By combining different technologies, we can create a robotic system that would detect a flame and extinguish it before it becomes disastrous. The requirements of such technology would require the robot to navigate through its environment, find the flame and safely extinguish it. A mobile robot with these characteristics involves many different disciplines. There are four main systems that create this robot; mobility, obstacle avoidance, flame detection and flame extinguishing. Mobility consists of motor control though programmable logic and circuit integration. Obstacle avoidance is designed through the relations between echo pulses and timing. Flame detection uses a novel search method based on algorithms for patterns of a flame. Lastly, the flame extinguisher uses the same system as a fire extinguisher would, except it uses water as a source. Analysis and design of fuzzy control laws are implemented to create the robots behaviours. Using these systems we can create a low cost robot that would help to bring technologies home.
