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:

    “Europe has what we do not have yet, a sense of the mysterious and inexorable limits of life, a sense, in a word, of tragedy. And we have what they sorely need: a sense of life’s possibilities.”
    —James Baldwin (1924–1987)

    “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)

    “Holly: Oh, Brad, I’d do my act in clown alley or the horse stop for you. I’d do anything if it was just for you.
    Brad: Pigeon, look. Out under the sky you know how I feel about you. But under the Big Top one performer’s just like another to me.”
    —Fredric M. Frank (1911–1977)
