Some Remarks on the RRR Linkage

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

The variety of rigid-body displacements of the final link of a 3 R kinematic chain are investigated. In most cases the variety generated is a Segre manifold; the Cartesian product of three projective lines. The homology of this variety as a subvariety of the Study quadric is found and simple applications to some enumerative problems in kinematics are given. The conditions for the variety to fail to be a Segre variety are investigated in full and the case where the linkage forms the first three joints of a Bennett mechanism is examined.
