How It Works

The Arduino Based Fire Fighting Robot functions by combining electronic sensors, motor control, and automation logic to detect and put out small fires. At the front of the robot, three flame sensors are positioned to monitor different directions for infrared radiation given off by open flames. These sensors continuously send analog or digital signals to the Arduino Mega 2560 and Arduino UNO boards. When a fire is detected, the microcontroller processes the input data to determine the direction of the heat source. If the robot needs to turn or move toward the fire, the Arduino commands the L293D Motor Driver module to drive the two motors mounted on the robot chassis, steering the vehicle closer to the hazard. Simultaneously, an SG90 servo motor sweeps back and forth to aim a small aluminum can and a mini DC submersible pump attached to it. Once the robot gets close enough to the flame, the Arduino activates the pump, drawing water from a small reservoir to spray and extinguish the fire. The entire system is powered by a portable power bank or a 12V battery, making the robot fully mobile and autonomous during operation.

Frequently Asked Questions

Can I use just one Arduino board instead of both an Arduino Mega and an Arduino UNO?

Yes, the project lists multiple boards, but a single microcontroller like the Arduino Mega 2560 or Arduino UNO has enough input/output pins to handle all three flame sensors, the servo, the motor driver, and the pump.

How does the robot know which direction the fire is coming from?

By using three flame sensors placed at different angles, the Arduino can compare the signal readings from each sensor to identify which one detects the strongest infrared light, allowing the robot to turn toward that specific direction.

How is water supplied to the mini DC submersible pump?

The submersible pump is placed inside a small water container (such as a small plastic reservoir or cup) mounted on the chassis, and it pushes water through a tube toward the target when triggered by the Arduino.
