In this paper a task-oriented motion planning approach for general cooperative multi-robot systems is proposed. In order to derive a meaningful task formulation, a taxonomy of cooperative multi-arm systems of industrial interest is devised. Then, a workpiece-oriented general formulation for cooperative tasks is proposed, where the user is asked to specify the motion of the system only at the workpiece level, while the motion of the single arms in the system is computed via kinematic transformations between the relevant coordinate frames. Based on this task formulation, an instructions set is derived to extend classical programming languages for industrial robots to general multi-robot systems. In order to test the approach, a software environment has been built, composed of an interpreter of the language and the motion planning software.

Abstract
In this paper a task-oriented motion planning approach for general cooperative multi-robot systems is proposed. In order to derive a meaningful task formulation, a taxonomy of cooperative multi-arm systems of industrial interest is devised. Then, a workpiece-oriented general formulation for cooperative tasks is proposed, where the user is asked to specify the motion of the system only at the workpiece level, while the motion of the single arms in the system is computed via kinematic transformations between the relevant coordinate frames. Based on this task formulation, an instructions set is derived to extend classical programming languages for industrial robots to general multi-robot systems. In order to test the approach, a software environment has been built, composed of an interpreter of the language and the motion planning software.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
