FIRE FIGHTING ROBOT
Abstract -:
This paper describes the design and construction of a small autonomous robot. Fire Fighting Robot Competition. At the heart of the system is the ATMEGA32 microcontroller ATMEL. Program code to control the fire fighting robot is written in C language. The system controls two optically isolated stepper motors for precision movement. Furthermore, the robot performs analog to digital conversion on 6 infrared sensors: 4 for wall proximity detection, one to detect floor markings, and one for candle detection. The 4 proximity sensors utilize heterodyne modulation of the IR signals to reduce the effects of ambient lighting. The extinguishing system is comprised of a large fan salvaged from a toy hovercraft, and a 3.5kHz tone decoder circuit is used to start the robot and gain bonus point
