چکیده
Abstract Advanced mathematical tools are used to conduct research on the kinematics analysis of hybrid mechanisms, and generalized method concise transfer matrix obtained. In this study, first, according serial basic principles Lie groups algebras briefly explained in dealing with spatial switching differential operations screw vectors. Then, based standard ideas operations, for parallel mechanisms is derived, Jacobian Hessian formulated recursively a closed form. mapping relationship between joints corresponding equivalent series joints, forward two inverse methods examined. A case study performed verify calculated matrices wherein humanoid robotic arm parallel-series-parallel configuration considered as an example. The results simulation experiment indicate that obtained formulas exact proposed practically feasible.

A Lie group is, roughly speaking, an analytic manifold with a group structure such that the group operations are analytic. Lie groups arise in a natural way as transformation groups of geometric objects. For example, the group of all affine transformations of a connected manifold with an affine connection and the group of all isometries of a pseudo-Riemannian manifold are known to be Lie groups...

The goal of this paper is to study Lie groups, specifically matrix groups. We will begin by introducing two examples: GLn(R) and SLn(R). Then in each section we will prove basic results about our two examples and then generalize these results to general matrix groups.
