Architectural Dressage

You’ve likely already seen the large complex of buildings in Shanghai that was picked up as a single block and walked to an adjacent site by a phalanx of miniature robots. Then walked back into place again. The 432 individual machines used for the move were “actually omnidirectional modular hydraulic jacks that are capable of … Continue reading "Architectural Dressage"
