Animation showing the construction of a geared five-bar cognate linkages from an initial four-bar cognate. A five-bar linkage has two degrees of freedom, and thus there does not exist a five-bar linkage which is capable of acting as a cognate. [Note 1] However, it is possible to generate a 5-bar cognate using gears. Select four-bar linkage of ...

This list contains Germanic elements of the English language which have a close corresponding Latinate form. The correspondence is semantic—in most cases these words are not cognates, but in some cases they are doublets, i.e., ultimately derived from the same root, generally Proto-Indo-European, as in cow and beef, both ultimately from PIE *gʷōus.
Cognate object, a verb's object that is etymologically related to the verb; Cognate (kinship), person who shares a common ancestor; Cognate linkage, a kinematic linkage that generates the same coupler curve as another linkage of a different geometry; Cognate interaction, in immunology denotes the specific, contact-dependent interaction between ...

The Scott Russell linkage (1803) translates linear motion through a right angle, but is not a straight line mechanism in itself. The Grasshopper beam/Evans linkage, an approximate straight line linkage, and the Bricard linkage, an exact straight line linkage, share similarities with the Scott Russell linkage and the Trammel of Archimedes.

The linkage was first shown in Paris on the Exposition Universelle (1878) as "The Plantigrade Machine". [5] [3] The Chebyshev Lambda Linkage is a cognate linkage of the Chebyshev linkage. The Chebyshev Lambda Linkage is used in vehicle suspension mechanisms, walking robots, and rover wheel mechanisms.
