Smart Firefighting Robot Car with Auto & Manual Mode

Advanced Arduino Fire Fighting Robot Car with Auto Detection and Bluetooth Control

This Fire Fighting Robot Car is a complete smart robotics solution designed for students, hobbyists, and engineering projects. Built using Arduino Uno R3, this robot combines both manual Bluetooth control and automatic fire detection to create a real-world firefighting simulation system. It is ideal for science fairs, university final year projects, and STEM learning in Bangladesh.

In manual mode, users can control the robot car using a mobile app via HC-06 Bluetooth module, allowing full movement control and manual activation of the water pump. In automatic mode, the system uses three flame sensors positioned left, center, and right to detect fire sources. Once a flame is detected, the robot automatically activates the water pump and uses a servo motor to aim and spray water precisely.

This project, available at Biggan Project, is specifically designed for students in BD who want to learn robotics, automation, and embedded systems practically. With a strong PVC chassis, powerful motors, and efficient power system, it delivers both performance and durability for educational use in Bangladesh.
