Minimum inertial parameters of robots with parallelogram closed loops

Abstract

A symbolic method to determine the minimum set of inertial parameters of robots containing parallelogram closed loops is presented. The solution is obtained by determining the minimum inertial parameters of an equivalent tree structure. Then, the constraint equations of the closed loops are taken into account to get the global minimum inertial parameters. Direct general relations are obtained for the two steps.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
