Before Easter, most of us do not really want to think about heavy stuff. We are usually thinking more about eggs, sour rye soup, and whether on Easter Monday we will manage to walk a few steps without getting hit by a bucket of water. Of course, that depends on the weather too.

Dear confused reader, if at this point your face says WTF?, let me explain.

Traditionally, on Easter Monday in Poland, we splash each other with water. The custom goes back a long time and was linked to the arrival of spring. Water was meant to bring health and good luck. Today, like with many old traditions, the original meaning got a bit blurry. But the fun stayed. And trust me, it really stayed.

Back to the point.

Most of us play with water for laughs. Somewhere else, robots are already doing the same kind of job, except there is nothing funny about it.

A robot with a water cannon sounds a bit like a toy from a very ambitious street fair. Something between a childhood fire truck and a movie script that ends up on TV during the holidays. The problem is, these machines already exist. And they are not standing only at trade shows next to a rollup banner and a guy in a branded shirt. In several places around the world, they are actually helping firefighters go where a human should not be the first one in.

Costs are rising. Clients are paying slower. Hiring feels riskier than ever.

And every day brings another hit.

Staying standing isn’t about doing more. It’s about knowing what to do next.

A good example is the Thermite RS3, built by Howe & Howe and used by the Los Angeles Fire Department. LAFD officially introduced it on October 13, 2020, and shared one important detail right away. This robot was not bought to look nice at a press conference. It was used on its very first day of service. It is a tracked, remote controlled machine designed for situations where the risk for firefighters simply gets too high. LAFD pointed to large commercial fires, tanker fires, warehouse fires, and other places where keeping a safe distance really matters.

And that is what I find most interesting here. A firefighting robot does not look like some huge revolution. It looks more like a very common sense idea. If we have technology that can get closer to the fire than a human can, maybe that is exactly what mature automation should look like. Less flashy talk. More simple questions. Can we reduce the risk for people?

In Japan, they approached the problem the way the best engineers often do. They did not build just “a robot that sprays water.” They built a full system for places where a normal firefighter would face too much heat, too much danger, and too little room for mistakes. The target was large fires in petrochemical complexes. Not one container or one warehouse, but places where fire, fuel, high temperatures, and the risk of explosion can turn a rescue mission into a nightmare very fast.

And that is what makes this case so good. It was not one robot shown at an exhibition. It was a full lineup of machines designed to work together in a place too dangerous for people. The system included an aerial reconnaissance robot, a ground reconnaissance robot, a water cannon robot, a hose laying robot, and a transport and command vehicle. Each part had its own job. Some machines gathered data, some moved in with water, and others helped bring the firefighting line into areas where humans would normally have to go themselves.

What matters most is that this system did not stay at the concept stage. It was deployed with the Ichihara City Fire Department in Chiba Prefecture and trained for real use by firefighters. So again. Not a brochure. Not a visualization. Not a glossy promo video. A real attempt to build a system that can go in first when a real emergency happens.

And that is exactly why I like this example from Japan so much. It shows that in robotics, it is not always about one spectacular machine. Sometimes it is about a well thought out set of tools that together do something very simple and very important. They give people more distance from the fire, and a better chance to get home safe.

And finally, a case from South Korea, because it shows one important thing very clearly. These robots are no longer just experiments. Hyundai, together with the national fire authorities, built an unmanned firefighting robot for places where conditions are worst for humans. Thick smoke, poor visibility, high heat, and the risk of collapse. The machine is based on a multi purpose unmanned platform and it got what really matters in this kind of environment. A camera system for visibility in smoke, a 6x6 drive system for debris and rough ground, remote control, and a water cannon with a range of up to 50 meters. It also has its own cooling system so it can keep working when the area around it gets seriously hot.

But the most important part is this. The robot did not end up as a nice looking demo project. Hyundai said it was used during a factory fire in Eumseong on January 30, 2026. After several hours, the smoke and heat inside were still so severe that the robot was sent in. And that feels like a very good sign of the times. More and more often, the question is no longer whether a robot could help firefighters. The real question is whether it is ready for the moment when it really has to go first.

And for everyone who made it all the way here, I just want to wish you a good Easter. Peace, a bit of breathing room, good food, and time with the people close to you. Slow down for a moment, take two deep breaths, and get some real rest. And yes, I also wish you a proper Wet Monday. Just the right amount. For health, for luck, and for a good year ahead.

Thanks for today. Cheers, Jacek
