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:
“What a wonderful bird the frog are—
When he stand he sit almost;
When he hop, he fly almost.
He ain’t got no sense hardly;
He ain’t got no tail hardly either.
When he sit, he sit on what he ain’t got almost.”
—Unknown. The Frog (l. 1–6)
“Who is the happy Warrior? Who is he
That every man in arms should wish to be?
It is the generous spirit, who, when brought
Among the tasks of real life, hath wrought
Upon the plan that pleased his boyish thought:
Whose high endeavors are an inward light
That makes the path before him always bright:
Who, with a natural instinct to discern
What knowledge can perform, is diligent to learn;
And in himself posses his own desire;”
—William Wordsworth (1770–1850)
“You should try to understand every thing you see and hear; to act and judge for yourselves; to remember you each have a soul of your own to account for; M a mind of your own to improve. When you once get these ideas fixed, and learn to act upon them, no man or set of men, no laws, customs, or combinations of them can seriously oppress you.”
—Jane Grey Swisshelm (1815–1884)
