mechanism for square rotation

The mechanism performs an exact square trajectory using only one source of rotational input and without any constraints applied to the output point of motion.

It consists of three mechanical entities merged into an unitary mechanism: a four-bar linkage with parallel and equal cranks, a planetary gear arrangement and a periodic cam with two conjugated surfaces.
