Design and Implementation of Hardware's Firefighting Legged Robot

Abstract

This paper discusses about hardware design for firefighting legged robot. This research aims to design and make a robot control system hardware of firefighting legged robot. This research realize a firefighting legged robot contest, which using microcontroller of ATMEGA128. Robot search for fire and extinguish the fire in the changing space condition. It uses many kinds of sensor. Sound activation (sound sensor) is used to start all the process to be performed by the robot. Robot start navigation after sound activation has been activated. Sensor ultrasonic used to detect the distance to the wall. Line sensor is used to detect the white line when robot will enter the room and detect candle location. To detect light of candle, it used UVTron flame detector. When robot crashes the furniture so limit switch will be used for moving away from the crashed object. Robot must blow on a fire candle at candle location (white color). The tools used to turn off the flame is the fan (DC motor). The result show that firefighting legged robot has been function and working of the various sensors and controller. Overall, the system can work well and stable according desired requirement.
