Classical planners normally try to satisfy all goal states. But in an incomplete environment they cannot decide whether an unknown state is already satisfied or not. An unknown state like color(door, blue) could only be satisfied by painting the door blue. If the door is already blue, this action would be unnecessary, and a lack of blue paint would even entail an inconsistency. The ability to plan sensory actions too was realized in various STRIPS-based approaches, such as IPEM by Ambros-Ingerson and Steel [PUBLink], UWL and XII by Etzioni et al. [PUBLink] [PUBLink], Sage by Knoblock [PUBLink] and Occam by Kwok and Weld [PUBLink].
