Frontiers of Mechanical Engineering 2011, Volume 6, Issue 4,   Pages 397-408 doi: 10.1007/s11465-011-0228-9

Abstract:

In this paper, a topology is presented for feasible workspace regions in general two-revolute manipulatorsThe design problem and concept of feasible workspace regions have been discussed as linked to each otherDesign equations are formulated by arbitrarily prescribing four workspace boundary points.The so-called feasible workspace regions are the intersection of three different sub-regions, which aregiven by constraint curves as function of the relative positions of three workspace boundary points.
