Sense Plan Act

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
  3. Act

SPA is used in iterations: After the acting phase, the sensing phase, and the entire cycle, is repeated.


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

    “Beware thoughts that come in the night. They aren’t turned properly; they come in askew, free of sense and restriction, deriving from the most remote of sources.”
    —William Least Heat Moon [William Trogdon] (b. 1939)

    “I have always hated biography, and more especially, autobiography. If biography, the writer invariably finds it necessary to plaster the subject with praises, flattery and adulation and to invest him with all the Christian graces. If autobiography, the same plan is followed, but the writer apologizes for it.”
    —Carolyn Wells (1862–1942)

    “... whatever men do or know or experience can make sense only to the extent that it can be spoken about. There may be truths beyond speech, and they may be of great relevance to man in the singular, that is, to man in so far as he is not a political being, whatever else he may be. Men in the plural, that is, men in so far as they live and move and act in this world, can experience meaningfulness only because they can talk with and make sense to each other and to themselves.”
    —Hannah Arendt (1906–1975)
