"Perhaps it is because, at the initial design stage, the engineers of the Olorun Civilization did not consider interactions with 'aliens possessing a certain level of civilization.' Those robot clusters did not realize our presence. Of course, it is also possible that there are instructions in the robots' programs on how to deal with such situations, but they couldn't retrieve the relevant data in time—after all, that's the drawback of using magnetic tapes."
"The movements of those robots are very slow. When it comes to 'movement,' they usually have three pairs of legs and a track-gliding device. All three pairs of legs are used to latch onto the holes of corresponding sizes on the steel structure. With each step, they move two of the six legs, latch them into the appropriate structures, and then proceed to move the other two, repeating this process. Each step takes about eighty seconds."
