Autonomous fire truck

My take on a great little Arduino project - an Arduino Uno powered autonomous fire-truck. This truck, when equipped with all necessary components, will detect fire in a small radius around it, drive up to it to close proximity and fire up its water pump to spray water and extinguish the flame. Printed parts are specifically designed for specific parts, all from AliExpress really cheap. You need 2 IR flame sensors, 1 ultrasound sensor, 4 small N20 motors, 4 wheels, 5v water pump, a relay to switch the pump, Arduino uno, 2 motor controllers. 2 blue LEDs, a buzzer, some wires and a 5xAA battery pack, or any other power source really. If you want a schematics for this project and/or product links specifically, i can provide them on request :)
