Dawid Szmandra from Poland has built this giant LEGO Liebherr LR 11000 crane. Just to give you an idea how large this creation actually is, you can imagine when the carne arm is fully deployed it reaches out over a large living room. Watch his youtube video. It’s of course remote controlled with the scale 1:24 and weighs 27 kg. Has 4 EV3 bricks, 9 motors, 7 light sensors, 1 touch sensor. Made 99.9% out of LEGO, except the pulley wheels, stickers and strings.
