A robot senses, decides, then acts. Sensors are its eyes, ears and touch.
Bo only followed steps, so he bumped into the table. Steps say what to do, and sensors show what is there.
A sensor measures the world: light, sound, touch or distance.
A robot does three things over and over: it senses, it decides with a rule, and it acts.
A robot follows its rule using what its sensors tell it, and nothing more.
These are some of the questions on the sets. The printable sheets have more and an answer key.
A light sensor. A light sensor measures how bright it is.
Sensing. Reading a sensor is the sense part of the loop.
Acting. Turning a wheel is the act part of the loop.
Farther. The longer the ping takes, the farther away the table is.
False. A robot only knows what its sensors tell it.
Look for sensors with a grown-up: an automatic light, a door that opens by itself, a thermostat, a phone that turns its screen. For each, say what it senses, what the rule might be, and what it does. Sense, decide, act.
Look for sensors at home together: an automatic light, a door that opens by itself, a thermostat, a phone that turns its screen. For each, ask what it senses, what the rule might be, and what it does.
