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 theatre demanded of its members stamina, good digestion, the ability to adjust, and a strong sense of humor. There was no discomfort an actor didn’t learn to endure. To survive, we had to be horses and we were.”
—Helen Hayes (1900–1993)
“Tired minds don’t plan well. Sleep first, plan later.”
—Walter Reisch (1903–1963)
“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)
