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:
“You must always be puzzled by mental illness. The thing I would dread most, if I became mentally ill, would be your adopting a common sense attitude; that you could take it for granted that I was deluded.”
—Ludwig Wittgenstein (1889–1951)
“Make a plan and you will find she has something else in mind;”
—Alan Jay Lerner (1918–1986)
“But the whim we have of happiness is somewhat thus. By certain valuations, and averages, of our own striking, we come upon some sort of average terrestrial lot; this we fancy belongs to us by nature, and of indefeasible rights. It is simple payment of our wages, of our deserts; requires neither thanks nor complaint.... Foolish soul! What act of legislature was there that thou shouldst be happy? A little while ago thou hadst no right to be at all.”
—Thomas Carlyle (1795–1881)
