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:

    “What may this mean? Language of Man pronounced
    By tongue of brute, and human sense expressed!
    The first at least of these I thought denied
    To beasts, whom God on their creation-day
    Created mute to all articulate sound;
    The latter I demur, for in their looks
    Much reason, and in their actions, oft appears.
    John Milton (1608–1674)

    My plan of instruction is extremely simple and limited. They learn, on week-days, such coarse works as may fit them for servants. I allow of no writing for the poor. My object is not to make fanatics, but to train up the lower classes in habits of industry and piety.
    Hannah More (1745–1833)

    Once women begin to question the inevitability of their subordination and to reject the conventions formerly associated with it, they can no longer retreat to the safety of those conventions. The woman who rejects the stereotype of feminine weakness and dependence can no longer find much comfort in the cliché that all men are beasts. She has no choice except to believe, on the contrary, that men are human beings, and she finds it hard to forgive them when they act like animals.
    Christopher Lasch (b. 1932)
