LESSON 1 · 5 MIN
Sense, think, act
Every robot follows the same simple loop.
Robots sense the world with sensors — light, distance, touch, temperature.
A small computer (a microcontroller) thinks: it runs a program that decides what to do with the sensor readings.
Then the robot acts using motors, lights or speakers — and the loop starts again.
Key idea
Sense → think → act, over and over.
Try it
Pick a machine at home (like an automatic door). What does it sense, and how does it act?
