Input: orange crank. It receives rotation from the brown motor through a belt drive.
Output: blue table that translates in square orbit (green line).
The green slider has two pins. The lower pin has a revolution joint with the blue rectangular frame. The upper pin moves in slot of the yellow fixing plate. The slot shape determines the motion orbit of the blue output plate.
The pink middle plate has prismatic joints with the yellow and blue plates.
