A Remote Controlled Fire-Fighting Robot (RCFFR) is a mobile robot that approaches a fire while the operator stays at a safe distance. It carries a water/foam tank with high-pressure pump (or CO₂ canister), a pan-tilt nozzle, and flame/temperature sensors to locate hot spots. Control is wireless via RF, Bluetooth, or Wi-Fi/FPV, and the drive train uses geared DC/BLDC motors for strong torque. This project demonstrates wireless control, motor driving, fluid handling, safety design, and real-time video telemetry—perfect for diploma/degree students.

Parts Used:

1. Chassis & Drive – 4WD/Tracked base with metal frame and skid-steer turning.
2. Motors & Drivers – Geared DC/BLDC motors with H-bridge motor drivers (dual channel).
3. Microcontroller – Arduino/ESP32 or similar for drive, pump, and sensor control.
4. Wireless Module – RF/Bluetooth joystick link or Wi-Fi with app control.
5. Pump & Tank – 12 V diaphragm pump (3–6 L/min) with non-return valve and 1–3 L tank.
6. Pan-Tilt Nozzle – Servo-based 2-axis mount for directional spray; quick-disconnect hose.
7. Sensors – Flame (IR), temperature (NTC/MLX90614), optional gas (MQ-2) and smoke.
8. Camera (FPV) – Wi-Fi/analog camera with LED headlight for low-light operation.
9. Power System – 3S/4S Li-ion/LiPo battery, BMS, fuse/MCB, main switch, and wiring harness.
10. Safety – Emergency stop, current protection, low-voltage cutoff; waterproof enclosure.
11. Wheels/Suspension – High-grip tyres or tracks; optional spring bogies for rough terrain.
12. Accessories – Pressure gauge, flow control, cable management, carry handle.
