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:

    “The motive of science was the extension of man, on all sides, into Nature, till his hands should touch the stars, his eyes see through the earth, his ears understand the language of beast and bird, and the sense of the wind; and, through his sympathy, heaven and earth should talk with him. But that is not our science.”
    —Ralph Waldo Emerson (1803–1882)

    “The nonconformist and the rebel say all manner of unanswerable things against the existing republic, but discover to our sense no plan of house or state of their own.”
    —Ralph Waldo Emerson (1803–1882)

    “Raising a daughter is an extremely political act in this culture. Mothers have been placed in a no-win situation with their daughters: if they teach their daughters simply how to get along in a world that has been shaped by men and male desires, then they betray their daughters’ potential But, if they do not, they leave their daughters adrift in a hostile world without survival strategies.”
    —Elizabeth Debold (20th century)
