Humanoid robots are emerging one after another. If these can indeed be used to explore topics such as robot mobility, balance, and operations in disaster environments, then their development is meaningful. So, when can we expect to see firefighting and rescue robots that are as agile as human firefighters? Furthermore, it should be feasible for high-power diesel engine drones to directly carry fire hoses and fly to heights of a hundred meters, right? Recently, the weather has been quite nice, but unfortunately, in urban areas, those newly constructed high-rise buildings block much of the precious sunlight, obstructing the blue sky and limiting the view that could have been enjoyed. Much of human ingenuity seems to be spent on creating more foolishness.
