Synthesis of a Planar Five-Bar Mechanism Consisting of Two Binary Links Having Two Offset Tracing Points for Motion Between Two Extreme Positions

Abstract

A vast number of mechanisms have been synthesized to augment the requirements of automation industry, but still there is need to invent useful mechanisms. To bridge this gap and to fulfill the requirement of motion between two extreme positions, various planar kinematic linkage mechanisms have been proposed by different researchers. In this paper, an effort has been made to propose a mechanism along with its analytical dimensional synthesis that makes use of two binary links having two offset tracing points. The proposed mechanism transmits motion between two extreme positions by alternately temporarily fixing a different binary link in two distinct stages. The analytical equations have been written using dyadic and triadic approach of mechanism synthesis for common standard kinematic task of path generation. The proposed method is noniterative and reduces the solution space.

A new synthesis method for planar Rubik’s cube mechanism

“…Wen et al 36 investigated a stiffness synthesis strategy for 3RPR robots with desired stiffness at the elastic center. Nafees et al 37 carried out the synthesis of five-bar mechanism for two tracing points that generates the trajectory and transmits motion between two extreme positions. Huang et al 38 presented methods to realize an arbitrary 2×2 elastic behavior using three-joint serial mechanisms.…”

Kinematics of a 6-DOF parallel manipulator with two limbs actuated by spherical motion generators

“…The interest of this work is the design of a manipulator with only two limbs. The well-known two-limb PMs include the five-bar 2-DOF mechanism with either planar 18,19 or spatial linkages. 20,21 Based on planar five-bar mechanism, Gao et al.…”

A Five-Bar Planar Parallel Manipulator with Two End-Effectors

“…Eventhough its simplicity, the five-bar planar parallel manipulator, 5R mechanism for brevity, has been extensively studied approaching issues like inverse-forward kinematics, singularity analysis, optimal workspace, kinematic calibration, topology optimization, robot performance and so on, see for instance [2][3][4][5][6][7]. On the other hand as occur for most parallel manipulators, limited workspace is a drawback of the 5R mechanism, e.g.…”
