This work presents the implementation of an autonomous fire-fighting smart robot designed to extinguish fires autonomously in the fire-fighting sector. They may carry out responsibilities including looking for victims, removing debris, and putting out fires by adopting navigation and mapping. This work uses smart robots to support firemen in risky circumstances. Fire accidents are commonly occurring nowadays which are destroying the environment and mainly human power rebuilding all the things that are deployed requires a huge amount of capital. Hence, we came across the fire-fighting robot that senses the fire using a flame sensor and in return uses the water pump spray the water and turn off the fire, and the vehicle moves with the control of itself. For autonomous navigation in unfamiliar environments, the robot uses simultaneous localization and mapping (SLAM), which is enhanced by indoor positioning systems and GPS for robust maneuverability. This work aims to build a strong, cognitive robot that can identify and put out flames in various contexts, including homes and factories. This work was done with the use of the Internet of Things.
