A low cost sensor based autonomous and semi-autonomous fire-fighting squad robot

摘要

The use of robots in situations that can be too dangerous for human interventions is growing. Evolving sensor and mechanical advances, out dangers people from risk of fire hazards. This paper presents an intelligent multi sensor based autonomous & semi-autonomous robot, which rescues from fire accidents in common day-to-day life. The proposed robot can be materialized very economically, which constitutes six integral modules which includes its structure, obstacle avoidance & driver system, control system governed by a microcontroller, fire detection system, remote supervising system, Global System for Mobile communication module. In autonomous mode, when juxtaposed with a smoke detector, it takes lead as it can quench the fire at its inception than sitting tight for an object to smolder and create smoke. It voluntarily detects, navigates itself and extinguishes fire without any human aid, thus saving lives of many individuals. It also sends the emergency warning signal alerts to the security personnel in the duty and within reach fire station through the rooted GSM module. In semi-autonomous mode, this robot was designed to act upon voice commands as well as from a general user interface developed on the touch screen. This robot has added feature of operating in groups by communicating between them.
