While the LEGO Group produces an incredible range of specialized Technic pieces, they won’t always meet our needs. Sometimes we’ll need to combine pieces to create mechanical solutions we find in the real world. This is the subject of this chapter: mechanisms that extend the functionality of your constructions beyond the limits of ready-made LEGO pieces. Here you’ll find mechanisms that transform one type of motion into another, that take basic LEGO lights and transform them into sophisticated signaling systems, and much more.
These mechanisms are fun to build just on their own as explorations of mechanical engineering concepts, but you’ll also find them quite useful when building larger models.
