Chapter 4. Basic Kinematics of Constrained Rigid Bodies

The term kinematic pairs actually refers to kinematic constraints between rigid bodies. The kinematic pairs are divided into lower pairs and higher pairs, depending on how the two bodies are in contact. 4.2.1 Lower Pairs in Planar Mechanisms. There are two kinds of lower pairs in planar mechanisms: revolute pairs and prismatic pairs. A rigid body in a plane has only three independent motions ...

A kinematic diagram is a drawing of a mechanism show- ing its essential elements in simplified form with graphical symbols (Fig. 4). Although a great deal of effort has been made to normalize the graphical symbols for kinematic diagrams [27] [26] [28], the practice in the literature is just far from normalized. Similar to the kinematic diagram, the kinematic layout graph (Fig. 5) was proposed ...

The same 6-PSU kinematic diagram of the parallel manipulator was proposed by [15]. In the analyzed cases, each linear actuator consists of a drive and joints: the universal U, prismatic P, and spherical S.

Kinematic diagrams are constructed in this sketching mode to enforce the geometric constraints that map the prescribed performance input information to the synthe-sized mechanism. As an example of this mapping, consider the synthesis of a planar four-bar linkage for motion generation through five finitely separated positions. The coupler link is con-strained to have a specified position and ...
