planar linkage การใช้

It is common practice to design the linkage system so that the movement of all of the bodies are constrained to lie on parallel planes, to form what is known as a " planar linkage ".
In these examples the components in the linkage move in parallel planes and are called " planar linkages . " A linkage with at least one link that moves in three-dimensional space is called a " spatial linkage . " The skeletons of robotic systems are examples of spatial linkages.
