Although reconfigurable rigid-body mechanisms have been extensively studied over two decades, their compliant counterparts have not received the similar attention yet. This paper aims to design a reconfigurable compliant four-bar mechanism with multiple operation modes. A planar equilateral four-bar mechanism is considered at its constraint singularity. The multiple operation modes of this linkage are kinematically exploited to design a reconfigurable compliant four-bar mechanism, which generates rotational or translational motions based on two actuated joints. Simulation is conducted to investigate the comprehensive kinematics of the reconfigurable compliant mechanism. A 3D printed prototype of the novel reconfigurable compliant mechanism at hand is presented.
