Designing shoulder prostheses with a small pneumatic actuator driven parallel mechanism for spatial accessibility in daily living use.
Slider crank mechanism is usually used if the precise transfer of the rotation to the translation is required. Although, it has smooth operation, it is known that more efficient mechanisms are available especially in petrol and diesel engines. It is reported that Scotch yoke mechanism and inverted slider crank mechanism, equivalent to the slider crank mechanism in kinematically; have smoother operation and higher efficiency as compared to slider crank mechanism. In this paper, inversion of the double slider crank chain and slider crank chain, Scotch yoke and inverted slider crank are compared in terms of their performance under identical geometrical constraints and discussed the possible use in control actuation systems.
