Sense-Plan-Act was the predominant robot control methodology through 1985.

1. Sense - gather information using the sensors

2. Plan - create a world model using all the information, and plan the next move

3. Act

SPA is used in iterations: After the acting phase, the sensing phase, and the entire cycle, is repeated.
