“…They used the method of differential evolution to carry out the optimization. Chanekar and Ghosal [19] investigated an optimization method for synthesis of adjustable planar four-bar, crank-rocker mechanisms. A twostage method was used first to determine the parameters of the possible driving dyads in tracing multiple different and desired paths.…”

Synthesis of mechanisms for generation of space curve is a challenging task for designers of the mechanical systems. Least squares method (LSM) has been extensively used for optimization of both planar and spatial mechanisms. Modified least squares method is applied for optimum synthesis of a slotted link mechanism with flexibly attached slider for space curve generation to show the scope of the modified method for optimum design. An example problem is included to illustrate the application of the method. Results are compared with conventional LSM.

This article presents the kinematic analysis of a new class of mechanical devices called planar Reconfigurable Motion Generators (RMGs) for multi-phase motion generation tasks having only a slight change in the desired motion. The concepts of configuration matrices and state vectors are introduced as a novel way to represent planar RMGs. The kinematic analysis of a planar RMG in it’s initial configuration to determine the associated adjustable link lengths and angles is discussed. The adjustable link lengths are used to determine the link vector and state vector of a RMG. Future work will involve the application of configuration matrices and state vectors to aid in both systematic analysis and synthesis of RMGs.
