In an extraordinary display of engineering, century-old buildings in Shanghai are being moved back to their original locations - without dismantling a single brick.⁣ ⁣ These historic structures had been temporarily relocated to make way for underground construction. ⁣ ⁣ Now, they’re returning home atop 432 small, crawler-type robots, moving in perfect sync. The project is expected to finish on June 7.⁣ ⁣ #Shanghai #Engineering #HistoricPreservation #Robotics #UrbanInnovation #Shikumen
