Sense-Plan-Act was the predominate robot control methodology through 1985.
- Sense - gather information using the sensors
- Plan - create a world model using all the information, and plan the next move
- 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:
“I never had the sense of myself as an accomplished artist, and I always had to work three times as hard as anyone else to make my pieces as good as they could be. I am never completely satisfied. There always seems to be something just beyond my reach.”
—Toshiko Takaezu (b. 1922)
“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)
“And this must be the prime of life . . . I blink,
As if at pain; for it is pain, to think
This pantomime
Of compensating act and counter-act,
Defeat and counterfeit, makes up, in fact,
My ablest time.”
—Philip Larkin (1922–1986)
