On certain aspects of the zero reference position method and its applications to an industrial manipulator

摘要

AbstractThe zero reference position method, proposed by Gupta in 1981, is based upon an arbitrary choice of the zero reference position, the principle of displacement similarity, and the hand‐to‐the‐base sequence of changing the joint variables in a serial manipulator. Its applications in performing recursive computations, formulating explicit governing equations, and obtaining closed form solutions for serial manipulators are presented in this paper. A Bendix‐type of industrial robot is used for illustrating the closed form solution pr
