The task of modellinG and control of lightweight robots is directly related to a suitable motion planning and control.

Abstract
The task of modellinG and control of lightweight robots is directly related to a suitable motion planning and control. To achieve such results and increase performances, accurate dynamic models that take into account the usually neglected inertial and elastic terms can be adopted in model-based approaches. In this paper, the experimental validation of an effective method based on an Equivalent Rigid Link System approach has been assessed. To this end, a dynamic simulator implementing the formulation has been exploited and an experimental test-bench has been set-up. The experimental tests carried out with a benchmark L-shape mechanism show a good agreement between the numerical model and the experimental measurementsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
