This paper presents the experimental validation of a self-adjusting active compliance controller for n robots handling a concerning its compliant behaviour partly unknown flexible object. The control strategy is based on the decomposition of the 6n-dimensional position/force space and includes a feedforward and feedback level. For adjusting the controller to the in general unknown flexible behaviour, which is the main problem of the controller design, a quasi-static model of the system is derived for different contact cases of the object and a procedure is presented, which by use of this model is capable of determining the compliance of the considered system and therefore of adjusting the controller. Experiments with two pumatype robots show the applicability of the self-adjusting control strategy.
