Description:FIELD OF THE INVENTION
The present invention relates to a self-propelled firefighting robot that can be remote-controlled via wireless or mobile communications to fight a fire.
OBJECTIVES OF THE INVENTION
The objective of this invention is, therecreate robots thatcan work on their own or be controlled remotely. By using such robots, fire identification and rescue activities can be done with higher security without placing firefighters at high risk and in dangerous conditions. In other words, robots can reduce theneedforfirefighters togetintodangerous situations.
BACKGROUND OF THE INVENTION
Fire-fighting robots that are remote-controlled by radio or the like are used to fight a fire at a location that is too hazardous to access by a firefighter for fighting the fire source. The fire-fighting equipment equipped with a self-propelled water spray system is characterized by including one or more water supply systems that are permanently installed in wall surfaces or the like within a fire-fighting area to receive a Supply of fire extinguishing water under pressure from fire pump equipment, and a water spray system capable of being self-propelled which moves to the location of theaforementioned water Supply system installed near the location of occurrence of a fire to connect its water supply inlet thereto, thereby receiving a supply of fire extinguishing water under pressure for spray.
The present invention was developed given the aforementioned problems. It is, therefore, an object of the present invention to provide a fire-fighting robot that can quickly start to fight a fire occurring at a hazardous location that firefighters cannot access, and fight a fire occurring at any location without receiving a Supply of fire extinguishing Water.
According to the technology disclosed in the Patent Document, the fire-extinguishing water needs to be supplied uninterruptedly from the water supply system to the self-propelled water spray System via the water supply inlet. During the spraying of water, the water spray System thus cannot move away from the location of the water supply system, so when the location of a fire source is distant from the water supply system, the water must be sprayed thereon at a distance. Accordingly, there was a problem that such a fire could not be extinguished with reliability.
US6113343 discloses a robot especially adapted for use in hazardous environments and particularly adapted for explosive disposal. The robot includes a wheeled platform carrying a winder mechanism which ensures that the remote control cable will not be fouled by the robot or its attachments.
US7182144 discloses a fire-fighting robot that can quickly start to fight a fire occurring in a hazardous location, which is not readily accessible to firefighters. The firefighting robot is self-propelled and remote-controlled via wireless or mobile communications to fight a fire. The robot includes one or more fire extinguisher storage portions for storing fire extinguishers which provide a jet of a fire fighting agent from a jet outlet by depressing a lever, a jet control portion disposed in the fire extinguisher storage portion for depressing the lever, and alert outlet securing portion for detachably securing the jet outlet of the fire extinguishers.
SUMMARY OF THE INVENTION
In essence, the present invention contemplates a fire-fighting robot comprising or consisting of a frame assembly, a fire-extinguishing mechanism disposed within the frame assembly, and an outer housing enclosing the fire-extinguishing mechanism except an outwardly extending nozzle or water cannon. The robot also includes a caterpillar drive assembly including a left caterpillar drive unit including a left engine for rotating said left caterpillar in a forward and rearward direction and a right caterpillar drive unit and a right engine for rotating said right caterpillar drive unit in a forward and or a reverse direction. In addition, the robot includes first remote control means for controlling the engines to thereby position the robot concerning a fire, illumination means and video means for displaying an image of the area around said robot at a remote location and means for cooling the interior and exterior of said robot as well as a second remote control means for directing a flow of fire Suppressant onto a fire. The invention will now be described in connection with the accompanying drawings where in like reference numerals have been used to indicate like parts.

These types of sensors are used for short-range fire detection and can be used to monitor projects. This unit is mostly accurate up to about 3 feet.This sensor/detector can be built with an electroniccircuitusing a receiver like electromagnetic radiation. This sensor uses the infrared flame flash method, which allows the sensor to workthrough a coatingofoil,dust,water vapor,otherwise ice.
The Arduino UNO is a microcontroller board based on the ATmega2560(datasheet). Ithas54digitalinput/output pins (of which 14canbeusedasPWMoutputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, aUSBconnection, apowerjack, anICSPheader,andaresetbutton.Itcontainseverything needed to support the microcontroller; simply connect it to a computer with aUSB cable or power it with an AC to DC adapter or battery to get started.
The Arduino Uno has several facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega2560 provides four hardware UARTs for TTL (5V) serial communication. An ATmega8U2 on the board channels one of these over USB and provides a virtual COM port to software on the computer (Windows machines will need a .in file, but OSX and Linux machines will recognize the board as a COM port automatically. The Arduino software includes an aerial monitor that allows simple textual data to be sent to and from the board.
The RX and TXLEDson board will flash when data is being transmitted via the ATmega8U2 chip and USB connection to the computer (but not for serial communication on pins 0 and 1). A Software Serial library allows for serial communication on any of the Mega2560's digital pins. The AT mega2560 also supports I2C(TWI) and SPI communication.
An innovative breakthrough in autonomous fire suppression technologies is the Fire Fighting Robot, which is based on Arduino. This robot has a complex array of parts and functions that allow it to detect and put out fires without the need for human intervention.
The Arduino microcontroller, a flexible and adaptable platform at its heart, is what drives the robot's functions. The chassis offers the structural foundation for integrating all electrical components. It is usually made of lightweight yet robust components. Rechargeable batteries power the robot's wheels or tracks, which allow it to move around and navigate different types of terrain.
The Fire Fighting Robot's ability to identify and extinguish fires is a key component of its operation. The robot is outfitted with sophisticated sensors, including temperature, smoke, and flame detectors, which enable it to constantly monitor its environment for any indications of fire. When it detects something, it uses obstacle detection sensors to autonomously plan its path, avoiding obstacles and arriving at the fire location quickly.
When the robot reaches the fire, it activates its fire suppression mechanism. Usually, this system has a water container where firefighting supplies like foam or water are kept. The robot puts out the fire by spraying the extinguishing solution onto the flames with the help of actuators like pumps or nozzles. To transmit data, video feeds, or status updates in real-time to a remote operator or monitoring station, advanced versions could include communication modules.
The robot adapts its activities to changing fire circumstances and functions autonomously based on pre-programmed algorithms or real-time decision-making procedures. Tominimize hazards during firefighting missions, safety features such as emergency stop buttons, heat protection mechanisms, and fail-safes assure safe and reliable functioning.
The Arduino-based Fire Fighting Robot is significant because it can automatically reduce fire hazards, speed up reaction times, and improve safety in areas where fire occurrences are common. This creative solution demonstrates how safety and technology can come together to solve important problems that emergency response and fire departments confront. It does this by utilizing modern robotics, sensor technologies, and intelligent control systems.
