The application of newton‐euler recursive methods to the derivation of closed form dynamic equations

摘要

Abstract The article presents, in tutorial format, a development of the Newton‐Euler (NE) approach to the analysis of robot dynamics. Beginning with fundamental concepts drawn from vector calculus and mechanics, a set of recursive equations are developed which allow the calculation of the dynamics of a manipulator in closed form. An example based on conventional manipulator design is evaluated in some detail and shows that, for kinematic models of some complexity, the NE approach is as fast as other techniques based on Lagrangian methods for deriving closed form dynamical equations.
