Grade 6 · Technology · Lesson 29

Sensors, robots or micro:bit intro

A robot is a computer with a body. It senses the world, runs a program, and acts on what it learns. The same loop — input, process, output — runs inside every smart device, from a self-driving car to a pocket-sized board called the micro:bit.

What this lesson teaches

2Match common sensors to the kind of input they detect
3Sort actions a robot can do into Input and Output categories
