This paper describes an efficient procedure to rectify circuit defects in rocker-crank and double-rocker at the synthesis level based on the angular joint displacements. This method complements the crank-rocker and double-crank circuit rectification to complete the circuit rectification of four-bar linkages. The procedure utilizes the algebraic method where special points followed by a line construction procedure are employed to validate the range of the critical angle that can identify the circuit defects as a function of the design positions prior to the completion of the linkage. As a result, a direct technique is implemented at the computational level to efficiently identify the infeasible solutions.
