🚜⚙️ ▭▭▭▭▭▭▭▭▭▭▭▭▭▭▭▭▭ A Soviet Walking Excavator, built in the USSR (1979)— a remarkable blend of engineering and innovation. 🧱 Nicknamed “STR-1,” this giant machine could literally *walk* on its mechanical legs instead of rolling on wheels or tracks! 🦾 Only six prototypes were ever made. They were designed for tough terrains like swamps, rocky hills, and Siberian tundra. ❄️🌍 A true mechanical marvel — decades ahead of its time. 🤖🇷🇺 ▭▭▭▭▭▭▭▭▭▭▭▭▭▭▭▭▭
