The article "Firefighting robots go autonomous" (Little,2021),discussed the capabilities and benefits of these robots. 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 (Little. 2021). With technological advancement, firefighters are now equipped with robots to aid their work. The Los Angeles City Fire Department can be seen using robots to aid them, with one of the robots being the Robot System 3 (RS3). The $300,000 RS3 was funded by the American Firefighting Foundation, the unit is capable of blasting water 10 times the rate of a conventional fire hose and has four cameras that can show where the water is being sprayed and thermal sensory capability that can detect victims (Little,2021). The LAFD assistant chief Wade White stated that " it has met some of these real-world mobility challenges and proved useful by dragging hose lines up steep hills and even pulling horses out of mud quagmires."(Little,2021, para.7).According to Eastern Kentucky University online(July 2020)the main function of a firefighting robot is to be able to analyse and find flames, carry out search and rescue operations, keep an eye on potentially dangerous factors, and perform the main work of controlling and suppressing fire and the RS3 have serval camera to do the job. Despite RS3 having several limitations and cost inefficiency, the capability of being able to spray water from a great distance and being able to tow items up to 8000pounds and lastly the ability to go through routh terrain to locate casualty with its rubber tracks and it high volume and low center of gravity. These functions are essential to reduce the risk of danger of firefighter.

 

Because of the RS3 being able to spray water from a great distance, the first features of the RS3 that can reduce the risk of fire fighter is the nozzle that is equipped with camara that can assist firefighter from a distance to locate the fire. It also can eject form or water with a speed of 2500 gallons per minute (Giuliani-Hoffman,2022). The functionalities eliminate the need for firefighters to enter the fire zone first, therefore reducing the risk of them losing their lives. These functions can also be seen in other tank like robots, which is used by the New South Wales Fire Rescue Teams (FRNSW), Turbine Aided Firefighting 20 (TAF20) (Government computer News,2021), Minister for Emergency Services, David Elliott, and Fire & Rescue NSW (FRNSW) Commissioner, Greg Mullins, state that AUD$310,000 is funded by the NSW government to build the TAF20. The nozzle of TAF20 can eject 3500 of water in one minute (EKU online, 2020). Like the RS3, TUF20 can be controlled manually by firefighter 500 meters away (EKU online,2020). The efficacy of the RS3 nozzle is nearly three times greater than the TAF20, even though both robots have identical features and are in the same price range. This demonstrates that the RS3 is superior to other comparable robots and has the capacity to lower firefighter danger. 

 

Another feature that the firefighting robot is capable of towing items up to 8000 pounds,Giuliani-Hoffman (2021) states that the winch of the RS3 have the strength to tow 8000 pounds that can pull away any obstacle blocking its way. (Giuliani-Hoffman,2020, para4). This feature allows the robot to move away obstacle blocking its way and with the help of infrared camera it can help firefighters to locate the casualties.When compared to its organic brother, Thermite Robot System 1 (RS1), the winch of RS1 can only handle 5000lb and has a speed of 6mph while RS3 have a speed of 8mph (Howe & Howe,n.d). From the data given by the organic company Howe and Howe, RS3 can do more heavy-duty stuff than RS1, which have proved that RS3 is better than its competitors in the market and this functions that RS3 have can reduce the death of firefighters. 

 

The RS3 is capable of traversing rugged and uneven terrain and withstanding exposure to the most harsh conditions. This is due to its 3500lb weight and incorporated industrial-grade belting rubber tracks. Howe&Howe (n.d.) To identify casualties, the characteristics allow it to travel with a slope of up to 50% and a side slope of up to 35% at a speed of 8mph. This demonstrates the fundamental requirement of what a firefighter robot should have in order to reduce the risk that the firefighter must take.

 

The RS3 is an excellent firefighting robot, yet it still has limitations. The robots are immobile since they require a hose to provide water to extinguish the fire. According to Little (2021) a group of students created a firefighting robot that can carry a water tank and a PC during the Mohamed Bin Zayed International Robotics Challenge. Its camera can identify and avoid obstacles, and it has a heat-sensor to detect and extinguish fires, like the RS3. Most importantly, this robot can be built with $40000 to $50000. This means that the new firefighting robots can solve the limitations that the RS3 has, and it is cheaper than RS3. However, the new robots are still prototypes that have not been used in real-life situations; thus, in the present market, I feel the RS3 are still the best Robots. 

 

 

In conclusion, firefighting robots are unable to fully replace humans in the current market, but after comparing three tank-like robots that have been developed, I believe that the functions of the RS3 are superior to all the other similar robots, making it the most capable of reducing the risk of life for the firefighters. According to Winton (2020), LAFD Chief Ralph Terrazas told Los Angeles Times “I can afford to lose one of these wonderful machines, I cannot afford to lose a firefighter” (Winton,2020, para.5). This has demonstrated that human life is the primary priority of the firefighting profession, and despite its limits and high cost, the RS3 can minimize firefighter danger.

Self introduction of myself

Subject: self introduction of myself Dear Professor Brad, My name is Lee Wei En, and the purpose of this email is to introduce myself. I received a diploma in mechatronics engineering from Temasek Polytechnic in 2020, and I'm currently enrolled in SIT's mechanical engineering program. After my internship I started to develop an interest in engineering. In order to land on a higher-paying job, my father wanted me to major in engineering. The interest of engineering did not become apparent to me until I completed an internship at Liebherr Singapore. There, I discovered how engineers use a variety of engineering skills to improve systematic ways to check products for quality before passing them on to customers. My interest grew after that and decided to continue studying to advance my engineering capabilities. My outgoing personality, which enables me to express myself in front of others, is a strength of mine. But only when I'm speaking Chinese. My weakness is that I read

paraphrasing of Gilbert Amelio statement

Original statment from Gilbert Amelio "Developing excellent communication skills is absolutely essential to effective leadership. The leader must be able to share knowledge and ideas to transmit a sense of urgency and enthusiasm to others. If a leader can't get a message across clearly and motivate others to act on it, then having a message doesn't even matter." Gilbert Amelio, former President and CEO of National Semiconductor Corp According to former president and CEO of National Semiconductor Corp, developing communication skills is essential to get the correct message and emotions across to the receiving parties. it is important for a leader to convey the correct message, in order not to cause a misunderstanding. The leader choice of words is how he/she present.  I t must be able to captivate and motivate the receiving parties, in order for them to act upon his/her words. It will be a waste of effort if no one understands and doesn’t do what he/she conveyed.
