This was shown at LEGO World 2013 and took three designers to create.

This packaging line uses multiple EV3 units to pick and place parts, making mini LEGO sets. Feed it with raw bricks and it builds little LEGO cars. Of all of these assembly lines, the one that I find the most impressive myself is a model car assembly line. The sheer cool factor of seeing a working miniature factory right there in your house cannot be denied. There have been more than a few people who have used their Mindstorms to build working assembly lines to make all sorts of useless, but cool things. This includes the single EV# P-brick, two actuators, and four motors to accomplish the amazing feat of turning one incredible machine into another incredible machine. There are about 650 LEGO pieces in total. It uses a cheap ABS-plastic filament pen as the print head. The EV3Dprinter makes use of one major non-LEGO component. While Mindstorms are pretty expensive, it’s nothing compared to the cost of even an entry-level 3d-printer.

The tech in question is, of course, a 3D printer – a machine that takes digital plan and then recreates it as a solid structure. This is a good thing, because these crazy people decided that they would try to build another type of cutting-edge technology by using LEGO. It’s a system with a lot more capability than people may give it credit for, and it will give the average smartphone a run for its money in terms of processing power. The EV3 kit is the current darling of the Mindstorms range at the moment, and it’s involved in just about every build you see here. While there are, of course, many LEGO projects in other ranges such as Technic or just plain old LEGO that are plenty impressive, the addition of the Mindstorms intelligence, motors, and various sensors means that these creations deserve to stand on their own. While the pre-made sets are fiendishly challenging by themselves, there are some people out there who simply can’t get enough of the robotic wonder toy from the plastic brick makers, so they end up birthing unbelievably creative and often useful machines that must be seen to be believed. No other toy has unlocked the diabolical engineer within the hearts of the masses as much as LEGO Mindstorms.
