Sense-Plan-Act was the predominate robot control methodology through 1985.

  1. Sense - gather information using the sensors
  2. Plan - create a world model using all the information, and plan the next move

Famous quotes containing the words sense, plan and/or act:

    “It is merely a linguistic peculiarity, not a logical fact, that we say “that is red” instead of “that reddens,” either in the sense of growing, becoming, red, or in the sense of making something else red.”
    —John Dewey (1859–1952)

    “People commonly educate their children as they build their houses, according to some plan they think beautiful, without considering whether it is suited to the purposes for which they are designed.”
    —Mary Wortley, Lady Montagu (1689–1762)

    “It is not enough to ask, ‘Will my act harm other people?’ Even if the answer is No, my act may still be wrong, because of its effects on other people. I should ask, ‘Will my act be one of a set of acts that will together harm other people?’ The answer may be Yes. And the harm to others may be great. If this is so, I may be acting very wrongly, like the Harmless Torturers.”
    —Derek Parfit (b. 1943)
