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:

    “Our sense of these things changes and they change,
    Not as in metaphor, but in our sense
    Of them. So sense exceeds all metaphor.
    It exceeds the heavy changes of the light.
    It is like a flow of meanings with no speech
    And of as many meanings as of men.”
    —Wallace Stevens (1879–1955)

    “The Lord wrote it all down on the little slate
    Of the baby tortoise.
    Outward and visible indication of the plan within,
    The complex, manifold involvedness of an individual creature”
    —D.H. (David Herbert)

    “Awareness has changed so that every act for children, every piece of legislation recognizes that children are part of families and that it is within families that children grow and thrive—or don’t.”
    —Bernice Weissbourd (20th century)
