To help celebrate the 2012 FIRST LEGO League (FLL) World Festival in St Louis, Mo., USA this April, this NXTLOG challenge theme is FOOD FACTOR! Your challenge is to develop a robot that can be used to innovate the food industry. Everything from helping grow and pick food fresh from the farm to how it can be safely transported, stored, served, and even turned into renewable energy! Make sure to clearly document in your NXTLOG what job your Food Factor LEGO MINDSTORMS NXT robot is designed to do. There's no limit on amount of LEGO MINDSTORMS NXT sensors, LEGO MINDSTORMS RCX sensors, motors, NXT programmable bricks, HiTechnic sensors, Codatex RFID sensors, or Bluetooth communication you can use.  Comment and tell what you think of this challenge.

Many robots are designed to do simple tasks in an efficient way to make our lives easier. But what if robotic machines did simple tasks in an over-complicated way? That’s what we’re asking you to explore in this NXT building challenge. We want you to design a LEGO MINDSTORMS NXT Crazy Contraption to perform a simple job like turning a page or clicking a LEGO brick, but in the most creatively complicated way you can imagine. Yes we’re inspired by the work of Rube Goldberg for this one! There's no limit on amount of LEGO MINDSTORMS NXT sensors, motors, NXT programmable bricks, HiTechnic sensors, or Bluetooth communication you can use on your Crazy Contraption robot.  Although this Contest is done, we do not know the winners. We will post them as soon as we find out. Right idkwhoyouare? Yes (idkwhoyouare)
