Zhu Weiwen said in Hong Kong and Taiwan's "Millennium Times" that during the fire of the CLP Cable Bridge, there was a certain crisis in water fighting, and the bridge had collapsed, and he was worried about further collapse or other hidden crises, describing it as "one more difficulty in the midst of difficulties". ”, while the fire-fighting robot adopts a modular design, which can activate the fire-fighting mode and go to a relatively dangerous place for rescue. The operator can control it at a distance of 500 meters. Hiding the fire or heat source is helpful for post-mortem review and scientific research, and also protects the safety of frontline personnel.
At present, the fire-fighting robot is operated by trainees of the indoor pyrotechnic characteristics training group, and will be used by more special teams of the Fire Services Department in the future.
When asked about the limitations of fire-fighting robots, Zhu Weiwen said that the first-generation robot had participated in the rescue of the Notre Dame de Paris fire in 2019, saying that it could span obstacles with a height of 30 cm, and stairs or slopes with an inclination of 40 degrees. It is easy to handle, with a width of 78 cm, and it can also enter and walk in water. He bluntly said, "The test found that it is very powerful... It is very moderate, and it has achieved a good balance between size and equipment."
He also pointed out that the fire-fighting robot can activate the incident support mode within a few minutes to assist in transportation, and the water output can reach 3,000 liters per minute, which is more than the 470 liters and 1,230 kilograms per minute used by frontline personnel. , the range can reach 60 meters, reducing the physical energy consumption of frontline personnel.

Zhu Weiwen said that the use of such robots is ever-changing. For example, when a super typhoon hits the port, it faces many fallen trees, causing traffic congestion. In the past, it was necessary to deploy cranes and manual cleaning, which was relatively slow. Robots can handle 800 The kilogram obstacle can open the road in a short time, and its possibilities are constantly being explored.
