The FireGuard is a firefighter robot concept, designed to eliminate the exposure of firefighters on fire and toxic smoke, and getting killed or injured. An operator, with the help of the built-in cameras and sensors, will send radio-frequency instructions to move the robot to the fire source even in dark smoke and extinguish fire with extinguishing agents from its tanks. Moreover, the sensors can transmit information about any gases or toxic substances inside the fire source. This robotic concept is equipped with a five-star rim engine, making it able to move inside places that are difficult to access like depots of dangerous goods, nuclear power plants or chemical plants. The lightweight construction of FireGuard allows it to move easily and systematically, and uses very small amount of extinguishing agents by featuring a rotating precision spray.
