LESSON 1 - ROBOT SENSES

PPreparation

1. Connect sensors to LOFI Brain (pay attention to numbers of inputs!): 2. Connect LOFI Brain with CHROME browser using LOFI Robot EXTENSION
3. Pay attention - connection works ONLY in CHROME we browser

Human senses

How do you think. What senses does human have? Try to guess its` names and type them below.


Hearing! Great!
What else?


"Senses" of a robot

Robot`s sensors works similar to human senses.
Try to guess what sensors could be used to to substitute the senses listed below.
Eyesight
Hearing
Smell
Sense of temperature
Sense of balance

What sensors will we use?

BUTTON












What can a simple button do?
Consider where can you fin a button in everyday objects?

POTENTIOMETER

Potentiometer is a rotary knob, whicha alows as control things in a smooth manner.
Where can we find potentiometers in everyday live objects?

What can be controlled with a potentiometer?

LIGHT SENSOR

Measures intensity of light - with light sensor we can detect if it is bright or dark in your surroundings.

Try to cover the light sensor with your hand or direct a flashlight on it.

Where can we find a light sensor in everyday conditions:

DISTANCE SENSOR

This sensor detects obstacles in front of it using ultrasonic sound waves.
It works similar to bio-sonars of dolphins and whales.

How can we make use of a distance sensor?

STOP

Summary

CONGRATULATIONS!
You made it to the end of this lesson.
Test what you learnt by answering three simple questions.

1. What type of waves does the distance sensor emmit?

2. How many senses does human have?

3. What sensor would fit best to controlling radio volume?
