The article "Fire fighting robots go autonomous" by Braxton (2021), discussed the capabilities of these particular robots and the benefits of these machines. With more than 350,000 American homes burning annually and climate change contributing to 10,000 active daily wildfires worldwide. Robots can offer some respite to firefighters entering blazing buildings or traversing steep mountains. Over 3000 Americans die from fires annually, which includes an average of 80 firefighters (Scientific American,  2021). With technological advancement, firefighters are now equipped with robots to aid their work. The U.S. Forest Service have been seen using in “remote controlled firefighting technology” to aid in their effort to reduce forest fires. The company have been testing and using remote controlled airdrop spheres called “dragon eggs”, these “eggs” are filled with potassium permanganate and glycol, and has the ability to keep the forest fuels at a more balanced levels. In the article, Braxton discuss in details about the RS3 used by the Los Angeles City Fire Department and goes through briefly about the firefighting drone. However, I believe that the flight capabilities and the enhance mapping system would have a greater impact in the efficiency of the firefighters, while putting them at a lower risk of injury or death. 

 

One of the ways that firefighting drone are able to increase the efficiency of firefighting is through being able to scale elevated places faster than the conventional method. Firefighters are required to fight wildfires on steep hills, thus, they are required to scale the forested hill to the fire while carrying all their gear while fighting adverse weather conditions. "The biggest challenges we face now are the strong winds and high temperatures. Also, the mountains are steep for firemen to climb up" (Yang, Fang, Zhang, 2020). These factors cause the firefighters to take a longer time to reach the locality and will be faced with fatigue once they begin fighting the fire. In order to tackle this issue, various researchers have conceptualise the idea of using swarms of autonomous drones capable of carrying a payload of 5 to 50 kilograms each, these drones would then fly in a grid formation to strategically put out the fire. Not only being able to scale up the steep areas but the drones can also be instantly deployed during the day or night due to them using a relocatable platform without requiring a nearby water source. In comparison to air/rotorcraft pilots and firefighters , these drones do not put the user's life at risk as they are fully autonomous.(Ausonio et al., 2021)

 

The other ways which these drones are able to aid the firefighters to be more efficient in their work is by improving their visibility. Currently, firefighters are limited to what they can see and information is being transmitted to them via radio from the headquarters (Spell, 2019), this causes a delay in their fight against fire as they are unable to get real-time updates. However, this will soon change as the drones that are being tested has “hazard mapping systems” that can give them “trusted information in real-time,” explained Andy Henson, vice president of artificial intelligence at Science Applications International Corp (SAIC). (Balch et al., 2022), examined that, in regards to tens of thousands of wildfires around the world, it was found that nighttime fires have increased by 7.2 percent since 2003. In the U.S., the rise has been 28 percent. Due to global warming, the temperature rises during the night, which reduces the moisture level the night air could previously hold, this effect was known as the “Vapour Pressure Deficit”. This effect will cause more wildfires to ignite during the night. (Nolan et al., 2016).

 

However, there has been a major concern about utilise robots to fight fire. One of their main limitation is , the cost of developing such a robot which specialises in emergency operation. The reason why the cost for these robots is much steeper, it could range from “$500 to $ 30,000 or more” (Anderson.n.d.).This is due to their enhance specification, these specification includes, being weather and fire resistant, the maintenance cost, insurance and sensors. (Radu et al., 2019). In addition to that, users would then have to go through a.drone program to get use to function of the drone, the average cost of a drone program would cost around $35,000 to $40,000 (Anderson.n.d.)

 

In conclusion, firefighting robots definitely increase the efficiency of firefighters. Where time is of the essence in their work, and seconds could lead to a life and death difference. Not only able to aid the firefighters to have better visibility in the dark, and able to scale places with fire faster than conventional methods. Notedly, one of the obstacles faced is the interference. However, the pros outweighs the cons by a landslide, thus, proving that the firefighting robots have the potential to increase the efficiency of the firefighters while reducing their risk of getting injured or dying.
