PEAS in AI

PEAS is how you write an agent’s job on the board. P Performance (what “good” means). E Environment (where it lives). A Actuators (what it can do). S Sensors (what it can see). Vacuum: P = dirt collected / energy; E = room tiles; A = move, suck; S = dirt, bump.

Self-drive sketch: P = safety + time; E = roads; A = steer, brake; S = cameras, lidar, GPS. If you skip PEAS, the agent discussion is just slogans.

PEAS in AI — output — four PEAS lines for a vacuum. Fill all four in the viva.

Diagram

P  performance  (clean tiles)
  E  environment  (room)
  A  actuators    (move / suck)
  S  sensors      (dirt / bump)

Exam tip

PEAS for vacuum or taxi. All four letters.

Example

# PEAS — vacuum
print("P: tiles cleaned / energy used")
print("E: two-room grid")
print("A: move, suck")
print("S: dirt sensor, bump sensor")
