It’s not uncommon for someone to build a car out of Legos, but it’s quite unusual for someone to build a working car assembly line from the plastic blocks. Someone in Germany has built quite a large contraption entirely of Legos that autonomously builds little cars.
Sure, the car itself is highly simplified, but it’s amazing that apart from three button pushes (choosing what colors are used), the entire process is automated - and in some cases, quite true to life (e.g. body drop, end-of-line roll-off). In the end, it’s a mix of industrial engineering and Rube Goldberg that is utterly fascinating to watch.
