An identification methodology for 6-DoF cable-driven parallel robots parameters application to the INCA 6D robot

Abstract

This paper proposes a methodology for the identification of the combined kinematic and dynamic parameters of a 6-Degrees of Freedom (6-DoF) Cable-Driven Parallel Robots (CDPRs) model. This methodology aims to ensure that the errors on the kinematic parameters do not affect the performances of the dynamic parameters estimation step. The proposed methodology has been implemented on a 6-DoF INCA robot. The identified model fits the system behaviour with good accuracy, and should then be used for the synthesis and analysis of kinematic and dynamic position / vision control strategies.
