A centrode, in kinematics
Kinematics is a subfield of physics, developed in classical mechanics, that describes the Motion (physics), motion of points, Physical object, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause ...
, is the path traced by the instantaneous center of rotation of a rigid plane figure moving in a plane. There are two types of centrodes: a space or fixed centrode, and a body or moving centrode.

*Four-bar_linkage
In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed- chain movable linkage. It consists of four bodies, called ''bars'' or ''links'', connected in a loop by four joints. Generally, the joints are configu ...
