Construct a Mechanical Crane

ByStrawbees Team

The mechanical crane is a three-dimensional four-bar linkage on a prism shape operated with a set of handles. The main mechanical advantage of this configuration of the four-bar linkage is that with a very little hand movement, it can generate a much larger movement for the arm and hook to grab objects.
