Abstract: The applicability and limitations of the present existence criteria for space mechanisms are discussed. The number synthesis technique is applied to the Kutzbach Criterion to identify all the ...

Abstract: The spherical drag-link mechanism has been designed using an approach based on minimum transmission angle. Explicit relationships have been derived for the required dimensions which satisfy the ...

Abstract: Thirty space, four-link mechanisms with two general constraints are investigated to study the existence of their coupler-curve cognates (Roberts’ cognates). The present study shows that the ...
