“…These include all isomers of the RRR, RRT, RTR and RTT dyads (see Table A1 in Appendix), the 6R triad, and the 6R tetrad (see Table A2 in Appendix). More details on the concept of dyadic isomers can be found [1] and [41].…”

“…In this paper the computer subroutines gathered in a suite named MeKin2D will be discussed. These have been grouped in libraries LibMec2D, LibMecIn, LibAssur and LibCams [1]. An additional library called LibPlots useful to generate graphs of various kinematic parameters of the mechanism will be also briefly introduced, as well as an AutoLisp application for involute gear generation within AutoCAD software [1].…”

“…It is relevant to mention that the kinematics of the geared dyad in Figure 11-a can be solved only iteratively, while the motion extractors in Figures 11-b and c are solvable analytically. Regarding the involute gear profiles occurring in some figures throughout the paper, these have been generated inside AutoCAD using an AutoLisp application named Gears.LSP and available with [1].…”
