In 1979, Soviet engineers debuted a mechanical titan called the ESH 6.5/45. Weighing 280 tons, it was too heavy for wheels or tracks, which would have seen it sink into the soft earth of Russian mines. Instead, they taught it to walk. Using two massive steel "shoes," the machine would lift its entire body, shift forward, and set itself down. Inside the cockpit, operators added a touch of home with lace curtains, creating a surreal contrast between domestic life and a massive walking monster.
