Watching This AI-Powered LEGO Brick Sorter Is Extremely Satisfying

The next time you clean up your LEGO collection, you're going to wish you had this machine at home to do the dirty work. Built pretty much entirely with LEGO pieces (plus a Raspberry Pi and some motors), this thing is able to sort virtually any LEGO piece that comes down its conveyer belts, thanks to artificial intelligence. It uses a neural network--or a set of algorithms that recognize patterns, similar to the human brain--to match the real-world LEGO pieces with 3D images of the pieces that the machine has been fed during training. The machine, which was built by YouTuber Daniel West, isn't the first of its kind--though it looks to be the most effective. There are plenty of other contraptions on YouTube showing crazy machines that others have built to sort LEGO bricks, like machines that sort LEGO axles, specifically, and others that spin plastic cups around to catch parts.
