WebFour links that are connected by four rotating joints. Three of the links can move, but the fourth is fixed in position. This link is called the ground link. One of the moving links is a crank that is rotated by a motor. As the crank rotates, it causes two other links to move while the ground link remains fixed in position. http://www-mdp.eng.cam.ac.uk/nagty/resources/enginfo/cookbook/machine/linkages/linkage_design.html creative depot blog
