🤖 Sense · Think · Act

Unit 1 · Robots & coding basics · 8 min

Every robot loops: Sense (sensors: camera, ultrasonic, touch) → Think (program: if… then…) → Act (motors, wheels, arm). A robot vacuum hits a wall → program decides → it turns.

Words in this lesson

• sensor — sensor
• motor — motor
• algorithm — algorithm

Project: Pick a home machine that "decides" (washer, AC…) and write its sense-think-act.
