In a vivacious and wondrous Lego parallel universe, we have come across robots, cars and, casemods. But the core essence of serious functionality takes a whole new level with the above pictured conception. Because, it is a full fledged working CNC Mill, remarkably created from the 'exalted' plastic bricks. Built from Lego's very own programmable Mindstorms NXT, the bantam setup does it all, even including the ubiquitously repressed sound effects of a running machine tool.
Lego introduced its Mindstorms NXT as a user friendly robotics kit back in 2006, with the 'intelligent brick' as the main component. The modders used this convenient capability to replicate a fully automated system, which sufficiently performs all the basic operations (along respective co-ordinates), albeit with a nigh imperceptible stutter. All the respective blocks were nicely placed, with the controlling intelligent brick fixed on the left side. The modder has also ingeniously utilized wheels (at an inverted position) for additional grip from the rubber facade.
Though, it should be duly noted that it is not the first CNC Mill created in Lego. And, even if we are not sure of its real working capacity, conceptions such as this certainly adds that strong flavor of practicality to the otherwise 'cute' world of Lego.
