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.

“A sense of the present
rises out of earth and grass,
enters the feet, ascends
into the genitals, constricting
the breast....”
—Denise Levertov (b. 1923)
“Solomon’s ... excess became an insult upon the privileges of mankind; for by the same plan of luxury, which made it necessary to have forty thousand stalls of horses,—he had unfortunately miscalculated his other wants, and so had seven hundred wives....
Wise—deluded man!”

“Remember that you are an actor in a drama, of such a part as it may please the master to assign you, for a long time or for a little as he may choose. And if he will you to take the part of a poor man, or a cripple, or a ruler, or a private citizen, then may you act that part with grace! For to act well the part that is allotted to us, that indeed is ours to do, but to choose it is another’s.”
—Epictetus (c. 55–135 B.C.)
