Need Input! Building a Remote Control Device

Abstract

Whatever you might do with LEGO MINDSTORMS NXT (autonomous vehicles, balancing walkers, brick sorters, line followers, and so on), one thing that still provides the most fun is controlling your creations remotely—at least for me. So, after having built an amazing model like JohnNXT, featuring any kind of functionality imaginable, I had to provide him with the “input” that he needed and that he was always looking for.
