INTRODUCTION

LEARNING POWERED BY LEGO®MINDSTORMS®EDUCATION

Since the beginning of this century, LEGO

MINDSTORMS

Education

has led the way in STEM (Science, Technology, Engineering, and Math)

Education, inspiring users to engage in fun, hands-on learning. The

combination of LEGO building systems with the LEGO MINDSTORMS

Education EV3 technology is now oﬀering even more ways to learn

about robotics and teach the principles of programming, physical

science, and mathematics.

The heart of LEGO MINDSTORMS Education is the EV3 Brick, the

programmable intelligent brick that controls motors and sensors,

as well as providing wireless communication. Choose what motors

and sensors you wish to use and build your robot just like you want

it to be.

Enter the LEGO MINDSTORMS Education EV3 Software to ﬁnd

everything you need. The EV3 Software Lobby gives you easy

access to content, programming, data logging, digital workbooks

and more. You can for example choose to follow the Robot Educator

and you’ll be able to create, program, and run a robot before you

know it. The intuitive icon-based programming is full of challenging

possibilities and the data logging environment provides a powerful

tool for scientiﬁc inquiry and experiments.

LEGO Education oﬀers a growing number of EV3-based curriculum

packages developed by experienced educators. We are committed

to responsive customer support, professional development, and

continuing education for teachers using MINDSTORMS robotics in

their classrooms.

Want to work like real scientists and engineers? Enter the LEGO

Education-supported FIRST

LEGO League and World Robot

Olympiad—and gain invaluable knowledge, life skills, and increased

self-conﬁdence!

We hope you enjoy the journey!

EV3 TECHNOLOGY

EV3 Brick

Overview

The Display shows you what is going on inside the EV3 Brick and

enables you to use the Brick Interface. It also allows you to add

text and numerical or graphic responses into your programming or

experiments. For example, you might want to program the Display

to show a happy face (or a sad face) for a comparison response or

to display a number that is the result of a mathematical calculation

(learn more about using the Display Block in the EV3 Software Help).

The Brick Buttons allow you to navigate inside the EV3 Brick

Interface. They can also be used as programmable activators. For

example, you might program a robot to raise its arms if the Up button

is pressed or to lower them if the Down button is pressed (for more

information, see Using the Brick Buttons in the EV3 Software Help).

EV3 TECHNOLOGY

The Brick Status Light that surrounds the Brick Buttons tells you

thecurrent status of the EV3 Brick. It can be green, orange, or red

and can pulse. Brick Status Light codes are the following:

+Red = Startup, Updating, Shutdown

+Red pulsing = Busy

+Orange = Alert, Ready

+Orange pulsing = Alert, Running

+Green = Ready

+Green pulsing = Running Program

You can also program the Brick Status Light to show diﬀerent colors

and to pulse when diﬀerent conditions are met (learn more about

using the Brick Status Light Block in the EV3 Software Help).

EV3 TECHNOLOGY

Installing Batteries

With LEGO®MINDSTORMS®Education EV3, you have the choice of

using normal AA batteries or the EV3 Rechargeable Battery pack

included in the LEGO MINDSTORMS Education EV3 Core Set.

If you experiment with both, you will ﬁnd that each option has

characteristics to consider when constructing your robots. For

instance, six AA batteries weigh more than theRechargeable Battery,

and the EV3 Brick with the Rechargeable Battery installed is slightly

larger than the EV3 Brick with six AA batteries.

The EV3 Rechargeable Battery is a convenient and economical

alternative to using AA batteries. It can be recharged while inbuilt in

a model, saving you the trouble of disassembling and reassembling

a robot to replace batteries.

To install the Rechargeable Battery on the EV3 Brick, remove

thebattery cover on the back of the EV3 Brick by pressing thetwo

plastic tabs on the side. If there are batteries in the EV3 Brick,

remove them. Insert the Rechargeable Battery in the slots that held

the battery cover in place and snap the battery in place.The battery

cover is not used.

If it is your ﬁrst use of the battery—or if the battery is completely

drained, let the battery and the EV3 Brick charge together for

minimum twenty minutes.

Using the enclosed power adaptor cord, connect the Rechargeable

Battery to a wall outlet. Make sure to keep the transformer cord and

battery where they will not be tripped over or get wet.

When you plug the uncharged battery into a wall socket, a red

indicator light will be lit. When charging is complete, the red light

will go out and the green light will be illuminated. The recharging

process will generally take three to four hours. If you use the EV3

Brick while the battery is charging, it will take longer. Before you start

to use the Rechargeable Battery for the ﬁrst time, it is recommended

that it is fully charged.

EV3 TECHNOLOGY

EV3 Brick

The EV3 Brick requires six AA/LR6 batteries if the EV3 Rechargeable

Battery is not used. Alkaline or rechargeable Lithium Ion AA batteries

are recommended. The AA batteries option is a good choice when

a little more weight is desirable in your robot.

To install the AA batteries, remove the battery cover on the back of

the EV3 Brick by pressing the two plastic tabs on the side. After you

have inserted the six AA batteries, attach the battery cover again.

SOME IMPORTANT INFORMATION ABOUT BATTERIES:

+Never use diﬀerent kinds of batteries together

(including mixing old and new).

+Remove batteries from the EV3 Brick when not in use.

+Never use damaged batteries.

+Use the correct battery charger under the supervision of

anadult.

+Never attempt to recharge batteries that are not rechargeable.

Note: If your batteries are weak, theBrick Status Light may stay red

after you press theStart button, while theDisplay continues to say

“Starting.”

POWER-SAVING PRACTICES

+Remove batteries between use.

Remember to keep each set of batteries in its own storage

container so they can be used together.

+Reduce Volume.

+Adjust Sleep Setting.

+Turn oﬀ Bluetooth and Wi-Fi when not in use.

+Avoid unnecessary wear on the motors.

Turning On the EV3 Brick

To turn on the EV3 Brick, press the Center button. After you press the

button, the Brick Status Light will turn red and the Starting screen

will be displayed.

When the light changes to green, your EV3 Brick is ready.

To turn the EV3 Brick oﬀ, press the Back button until you see theShut

Down screen.

The Abort X will already be selected. Use the Right button to select

the Accept check mark, then press the Center button for OK. Your

EV3 Brick is now turned oﬀ. If you press OK while the X is selected,

you will return to the Run Recent screen.
