Firefighting Robot with Face Detection System

摘要

Multi-sensor fire detection and a face detection system are developed for a fire fighting robot proposed in this work, to rescue human beings caught in fire. Various sensors like fire, smoke and infrared sensors have been incorporated in this robot. The infrared sensor detects any obstacle present in the path of the robot to help the robot navigate.While the fire sensor detects the fire in places like home, factories etc., the smoke sensor detects the smoke. The smoke can be caused either due to the fire or due to the leakage of flammable gases or flammable liquids. If the fire is detected, a water spraying mechanism is triggered. The robot is designed with a water tank and an attached pump. When the fire is detected, the relay gets energized and supplies power to the pump. The pump starts spraying water thereby extinguishing the fire. The face detection system alerts the presence of human beings caught in fire to facilitate their rescue.Text messages are displayed on the LCD upon all events to alert the operator.
