Designing a decoupled spherical parallel mechanism based on curved flexures: The development of a remote center of motion mechanism based on curved flexures and introducing a novel quantitative assessment method for rotary axis drift

Compliant mechanisms and decoupled parallel mechanisms are topics of high interest. The combination has been manifested for lower-mobility mechanisms, yet not attempted for higher degrees of freedom. The scarcity is countered by designing a decoupled compliant spherical parallel mechanism (DCSPM), having three independent rotational degrees of...

Modelling the axis drift of short wire flexures and increasing their support stiffness using polymers

For steel flexures, complex geometries are required to reach high support stiffness and limit axis drift over large ranges of motion. These complex flexures are expensive and difficult to manufacture. This paper presents a method of designing short, polymer wire flexures with high support stiffness and modelling their axis drift using a novel...
