I would disagree that digital robots are qualified to be called "anticipatory systems" as Rosen used the term. Rather, I would say that they are simulations of anticipatory systems. Anticipatory systems are complex systems [AS 425, EL 199]. A digital robot simulates in software the interaction of the components (model, effectors, etc.) that would be implemented in 'hardware' in a true anticipatory system. An anticipatory system embodies impredicative relations among these components.
I would agree that a digital robot can demonstrate an "anticipatory mode of control". Judith some time ago pointed out that a camera diaphragm mechanism [AS 41-42] also demonstrates an "anticipatory mode of control" but that it is not thereby an anticipatory *system*.
