In this paper, the regressor form of the dynamic equations is extended to include the case of serial manipulators with mixed rigid/elastic joints. Under the mild assumption of linearity of the nonlinear joint stiffness characteristics with respect to properly defined elastic parameters, a direct approach to the calculation of an augmented form of the regressor is proposed, where both inertial and elastic parameters appear in factored form. This allows off-line and on-line schemes to be applied for the concurrent identification of both inertial and elastic parameters. In the paper, the proposed methodology is fully detailed, and its application to a simple robot shows its effectiveness.

Abstract: | In this paper, the regressor form of the dynamic equations is extended to include the case of serial manipulators with mixed rigid/elastic joints.

This allows off-line and on-line schemes to be applied for the concurrent identification of both inertial and elastic parameters.
