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:
“The term clinical depression finds its way into too many conversations these days. One has a sense that a catastrophe has occurred in the psychic landscape.”
—Leonard Cohen (b. 1934)
“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)
“Adolescents may be, almost simultaneously, overconfident and riddled with fear. They are afraid of their overpowering feelings, of losing control, of helplessness, of failure. Sometimes they act bold, to counteract their imperious yearnings to remain children. They are impulsive, impetuous, moody, disagreeable, overdemanding, underappreciative. If you don’t understand them, remember, they don’t understand themselves most of the time.”
—Stella Chess (20th century)
