A considerable amount of research has been carried out on the synthesis of
mechanisms with linkages. Such mechanisms can be used in many ways and in
general, synthesis is carried out with reference to input positions and output positions.
In this study, the expert system analyzes the four bar double rocker mechanism for
given set of inputs which includes the distance of the ground pivots depending upon
the space constraint for the mounting of the mechanism, the angles of swing of the
input link and the angle of swing required by the output link. The results of the
kinematic synthesis and analysis module of the expert system have been compared
using a standard problem
