This is a video from Shanghai, China where 432 crawler robots were used to move an entire city block of historic buildings while underground construction was performed, then moved back after completion. The robotic feet were able to move the 7,500-metric ton block about 10 meters (33-feet) per day over the course of 20 days. Wow! Honestly, that’s about how fast I like to move too. Everyone else is always running around like hares, but I’m a tortoise. And we all know how that fable ends. Just kidding how does it end I haven’t finished reading it yet. I told you, I’m slow. My guess is a Ninja Turtle battle!
