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:

    “The evolution of sense is, in a sense, the evolution of nonsense.”
    —Vladimir Nabokov (1899–1977)

    “We saw the machinery where murderers are now executed. Seven have been executed. The plan is better than the old one. It is quietly done. Only a few, at the most about thirty or forty, can witness [an execution]. It excites nobody outside of the list permitted to attend. I think the time for capital punishment has passed. I would abolish it. But while it lasts this is the best mode.”
    —Rutherford Birchard Hayes (1822–1893)

    “You live in a puss-hole, you act accordingly.”
    —Guy Trosper, U.S. screenwriter, and John Frankenheimer. Robert Stroud (Burt Lancaster)
