The first five papers showcase the conception of novel architectures and innovative modeling and analysis methods. Gan, Dai, Dias, and Seneviratne propose a novel metamorphic parallel mechanism architecture capable of switching its motion between pure translation (3T) and pure rotation (3R) by virtue of a reconfigurable Hooke (rT) joint. Zhang, Laliberté, and Gosselin propose the development of passive force- and torque-limiting devices to ensure the safety of human–robot interaction and illustrate their use in a 2DOF planar serial robot. Almestiri, Murray, Myszka, and Wampler extend the singularity trace method to single-DOF closed-loop linkages with both revolute and prismatic joints to gain insights into gross motion characteristics of a linkage relative to a designated input joint and design parameters. A similarly insightful extension of kinematic mapping theory to facilitate planar discrete motion synthesis of an arbitrary number of approximated poses, as well as up to four exact poses, was offered by Zhao, Ge, Zi, and Ge. The work of Plecnik and McCarthy provides a nice segue from rigorous theory into the application areas in describing a synthesis technique that employs planar six-bar function generators to constrain a spatial serial chain to have a single-DOF, ultimately realizing a biomimetic flapping wing design.
