Development of Fire Fighting Robot (QRob)

Abstract

Fire incident is a disaster that can potentially cause the loss of life, property damage and permanent disability to the affected victim. They can also suffer from prolonged psychological and trauma. Fire fighters are primarily tasked to handle fire incidents, but they are often exposed to higher risks when extinguishing fire, especially in hazardous environments such as in nuclear power plant, petroleum refineries and gas tanks. They are also faced with other difficulties, particularly if fire occurs in narrow and restricted places, as it is necessary to explore the ruins of buildings and obstacles to extinguish the fire and save the victim. With high barriers and risks in fire extinguishment operations, technological innovations can be utilized to assist firefighting. Therefore, this paper presents the development of a firefighting robot dubbed QRob that can extinguish fire without the need for fire fighters to be exposed to unnecessary danger. QRob is designed to be compact in size than other conventional fire-fighting robot in order to ease small location entry for deeper reach of extinguishing fire in narrow space. QRob is also equipped with an ultrasonic sensor to avoid it from hitting any obstacle and surrounding objects, while a flame sensor is attached for fire detection. This resulted in QRob demonstrating capabilities of identifying fire locations automatically and ability to extinguish fire remotely at particular distance. QRob is programmed to find the fire location and stop at maximum distance of 40 cm from the fire. A human operator can monitor the robot by using camera which connects to a smartphone or remote devices.

Research on Fire Fighting Scheme of Indoor Fire Fighting Robot Based on Multi-sensor

“…The fire extinguishing scheme of multi-sensor fusion detection fire source for fire protection robot is experimentally verified. The following conclusions can be drawn by using candle to simulate indoor fire source: (1) After setting the distance between the robot and the fire source point, it can be found Fire source point and take the initiative to start the fire extinguishing program; (2) After the fire source point is found, the fire source can be fixed at a fixed point, and the water mist is continuously sprayed until the fire extinguishing source is extinguished ( Fig. 7 is the robot fire source detection and processing experiment).…”

“…Fire incidents can cause loss of life, property damage and permanent disability to affected victims, as well as long-term psychological and traumatic [1]. The source of urban fires is usually indoor fires, so it is especially important to prevent fires from the source [2].…”

A Smart Firefighting Robot System (LAHEEB)

“…6. It used to detect and measure the distance to targets in many automated factories and process plants [22]. To identify the presence of objects sensors with an on or off digital output is required, while sensors with an analog output which varies proportionally to the sensor to target separation distance are commercially available.…”

Attractiveness Analysis of Quiz Games

“…In terms of learning science, one can simply browse the Science Kids website, which offers experimental science and technology games for kids to learn science in interactive ways. Furthermore, machine learning [6][7][8][9][10], used within learning analytics, provides new insights into education processes. Currently, it is used to develop quiz games in order to make the educational processes in schools and universities more efficient for students and teachers.…”
