LEGO House of Cards Construction Machine

Arthur Sacek’s incredible robotic LEGO contraption constructs structures out of cards automatically.

If you’ve been stuck at home for the last year or so, you may have experimented with constructing card structures. These builds can provide much frustration and/or entertainment, and as shown at the beginning of the first video below, Arthur Sacek appears to be fairly good at this pastime. He’s so good, in fact, that not only can he put such a structure together by hand, but as reported on Gizmodo, he created a robotic LEGO contraption to do it for him.

The entire mechanism travels from placement point to placement point on a curved rail-like structure, and picks each card out individually with a mechanical arm for manipulation. As the house extends layer-by-layer off the ground, the internals extend with it for proper vertical positioning, seen in the second time-lapse card construction video.

The build was of course a massive undertaking, involving over 200 hours of time during nights and weekends for five months. While you might wonder how to assemble one yourself, he’s not providing instructions, nor is he planning to do another version. It seems he’s – understandably – had his fill of the project. It’s an amazing feat, and a true one-of-a-kind apparatus… until someone decides to follow in Sacek’s footsteps and make another!
