The goal of this research is to advance the synthesis methodology for designing coupler-drivers for actuating single degree of freedom mechanisms. A planar coupler-driver is a chain consisting of a fixed revolute joint, an actuated prismatic joint, and a moving revolute joint connected to an ideal location on a previously synthesized planar mechanism. Although such a chain may be connected between any fixed point and any moving point on the mechanism, the synthesis challenge is determining the locations of these points such that the mechanism moves over its desired range of motion without reaching a singularity. A singularity is a configuration of the mechanism at which it ceases to move. A spatial coupler-driver is defined by a chain consisting of a fixed spherical joint, an actuated prismatic joint, and a moving spherical joint connected to an ideal location on a previously synthesized spatial mechanism. This work addresses both planar and spatial coupler-drivers and uncovers challenges unique to each case.
