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:
“If an addict who has been completely cured starts smoking again he no longer experiences the discomfort of his first addiction. There exists, therefore, outside alkaloids and habit, a sense for opium, an intangible habit which lives on, despite the recasting of the organism.... The dead drug leaves a ghost behind. At certain hours it haunts the house.”
—Jean Cocteau (1889–1963)
“Make a plan and you will find she has something else in mind;”
—Alan Jay Lerner (1918–1986)
“Every act of conscious learning requires the willingness to suffer an injury to one’s self-esteem. That is why young children, before they are aware of their own self-importance, learn so easily; and why older persons, especially if vain or important, cannot learn at all.”
—Thomas Szasz (b. 1920)
