....detect occupied Sensing action to detect if a room is occupied. align Correct hardware uncertainty. Table 5: Basic actions 10.1 Universal plans and situation control rules Control modules as formulated in this paper have similarities with universal plans [Sch87] and triangle tables [Nil85] in the sense that for a set of situations they specify what the robot should do in each situation. The key difference is that Universal plans [Sch87, Sch89b, Sch89a, Sch92b] prescribe what actions need to be executed in each possible situation. In contrast our control modules only consider the ....

A Pattern-Weight Formulation of Search Knowledge - Levinson, Fuchs (1994)   (Correct)

....are unpredictable a certain percentage of the time a macro table may be endlessly returning the blank to the center since this is always the recommendation when the blank is not in its goal position. The basic reactive planning techniques such as STRIPS triangle table representation of macros [36] and Universal Planning [42] recover gracefully from interruptions but suffer from one of the two weaknesses of macro tables by being limited to a single subgoal sequence or not taking advantage of macro crossover. In PET [38] macro operators are decoupled into the form PRE state description ) ....

Universal Plans for Reactive Robots in Unpredictable Environments - Schoppers (1987)   (211 citations)  (Correct)

....This lack of symbols is somewhat disconcerting from a planning point of view. The REX project is emphasising analysis of the information content of situated automata synthesized by hand; I am emphasising the automatic synthesis and control of reactive behavior. Triangle tables (Fikes et al. 1972; Nilsson 1985) are synthesized by extracting, from a conventional linear plan, the set of expected world states and the set of needed operators, then reorganizing the predicates involved to form an index into that set of operators. This reorganization increases the competence of the original plan, from coping ....

The Uses Of Plans - Pollack (1992)   (33 citations)  (Correct)

....the block in Shakey s path, many planning systems were augmented with replanning capabilities. Usually, these consisted of techniques for reusing as much of the already computed plan as possible. The triangle table that Shakey exploited in replanning is an early example of a plan reuse mechanism [50]. Plan reuse has today become the object of increasingly sophisticated study (e.g. 38] But, although traditional systems allowed for replanning, they assumed that during replanning, the world was, once again, unchanging. Thus the fundamental picture underlying work in replanning is virtually ....
