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 at
least 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 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.

EV3 Motors
Large Motor
The Large Motor is a powerful ‘smart’ motor. It has a built-in Rotation
Sensor with 1-degree resolution for precise control. The Large Motor
is optimized to be the driving base on your robots.
By using the Move Steering or Move Tank Programming Block, the
Large Motors will coordinate the action simultaneously.
Medium Motor
The Medium Motor also includes a built-in Rotation Sensor (with
1-degree resolution), but it is smaller and lighter than the Large Motor.
That means it is able to respond more quickly than the Large Motor.
The Medium Motor can be programmed to turn on or off, control its
power level, or to run for a specified amount of time or rotations.
COMPARE THE TWO MOTORS:
+The Large Motor runs at 160–170 rpm, with a running torque of
20 Ncm and a stall torque of 40 Ncm (slower, but stronger).
+The Medium Motor runs at 240–250 rpm, with a running torque
of 8 Ncm and a stall torque of 12 Ncm (faster, but less powerful).
+Both motors are Auto ID supported.
For more information on using the Rotation Sensor in your
programming, see Using the Motor Rotation Sensor in the EV3
Software Help.

Colour Sensor
The digital Colour Sensor can detect the colour or intensity of any
light that passes through its lens. This sensor can be used in three
different modes: Colour Mode, Reflected Light Intensity Mode, and
Ambient Light Intensity Mode.
In Colour Mode, the Colour Sensor recognizes seven colours –
black, blue, green, yellow, red, white, and brown – plus No Colour.
This ability to differentiate between colours means your robot might
be programmed to sort coloured balls or blocks, speak the names
of colours as they are detected, or stop action when it sees red.
In Reflected Light Intensity Mode, the Colour Sensor measures the
intensity of light reflected back from a red light – emitting lamp. The
sensor uses a scale of 0 (very dark) to 100 (very light). This means
your robot might be programmed to move around on a white surface
until a black line is detected, or to interpret a colour-coded
identification card.
In Ambient Light Intensity Mode, the Colour Sensor measures the
strength of light that enters the window from its environment, such
as sunlight or the beam of a torch. The sensor uses a scale of 0
(very dark) to 100 (very light). This means your robot might be
programmed to set off an alarm when the sun rises in the morning,
or stop action if the lights go out.
The sample rate of the Colour Sensor is 1 kHz.
For the best accuracy, when in Colour Mode or Reflected Light
Intensity Mode, the sensor must be held at a right angle, close to
– but not touching – the surface it is examining.
For more information, see Using the Colour Sensor in the EV3
Software Help.

Gyro Sensor
The Gyro Sensor is a digital sensor that detects rotational motion
on a single axis. If you rotate the Gyro Sensor in the direction of the
arrows on the case of the sensor, the sensor can detect the rate of
rotation in degrees per second. (The sensor can measure a
maximum rate of spin of 440 degrees per second.) You can then
use the rotation rate to detect, for example, when a part of your
robot is turning, or when your robot is falling over.
In addition, the Gyro Sensor keeps track of the total rotation angle
in degrees. You can use this rotation angle to detect, for example,
how far your robot has turned. This feature means you are able to
program turns (on the axis the Gyro Sensor is measuring) with an
accuracy of +/- 3 degrees for a 90-degree turn.
Note: The sensor must be completely motionless while being
plugged into the EV3 Brick. If the Gyro Sensor is attached to a robot,
the robot should be held motionless in its starting position as the
Gyro Sensor is plugged into the EV3 Brick.
CONNECTING THE GYRO SENSOR
On the EV3 Brick, go to the Brick App screen (third tab) and use the
Centre button to select Port View.
Using a flat black Connector Cable, connect the Gyro Sensor to the
EV3 Brick on Port 2. Make sure to hold the sensor very still while
you do this. On the EV3 Brick display, the Port View app should show
a ‘0’ reading in the second small bottom window from the left, which
is the window representing input values from Port 2.
Still without moving the sensor, observe the display for a few seconds.
It should continue to display ‘0’ for Port 2 with the Gyro Sensor. If
the Gyro Sensor readings do not constantly display ‘0’ during the
connection process, unplug the sensor and repeat the procedure.
When the screen consistently displays ‘0’ for a few seconds,
experiment with rotating the sensor and observe how the angle
reading changes. Remember, the Gyro Sensor measures the angle
of change on only one axis.

Help.

Touch Sensor
The Touch Sensor is an analogue sensor that can detect when the
sensor’s red button has been pressed and when it is released. That
means the Touch Sensor can be programmed to action using three
conditions – pressed, released, or bumped (both pressed and released).
Using input from the Touch Sensor, a robot can be programmed to
see the world as a blind person might, reaching a hand out and
responding when it touches something (pressed).
You might build a robot with a Touch Sensor pressed against the
surface beneath it. You might then program the robot to respond
(Stop!) when your robot is about to drive off the edge of a table
(when the sensor is released).
A fighting robot might be programmed to keep pushing forward
against its challenger until the challenger retreats. That pair of
actions – pressed, then released – would constitute bumped.

Software Help.

Ultrasonic Sensor
The Ultrasonic Sensor is a digital sensor that can measure the
distance to an object in front of it. It does this by sending out high-
frequency sound waves and measuring how long it takes the sound
to reflect back to the sensor. The sound frequency is too high for
you to hear.
Distance to an object can be measured in either inches or
centimetres. This allows you to program your robot to stop a certain
distance from a wall.
When using centimetre units, the detectable distance is between 3
and 250 centimetres (with an accuracy of +/- 1 centimetres). When
using inch units, the measurable distance is between 1 and 99
inches (with an accuracy of +/- 0.394 inches). A value of 255
centimetres or 100 inches means the sensor is not able to detect
any object in front of it.
A steady light around the sensor eyes tells you that the sensor is in
Measure Mode. A blinking light tells you that it is in Presence Mode.
In Presence Mode, this sensor can detect another Ultrasonic Sensor
operating nearby. When listening for presence, the sensor detects
sound signals but does not send them.
The Ultrasonic Sensor can help your robots avoid furniture, track a
moving target, detect an intruder in your room, or ‘ping’ with
increasing volume or frequency as an object gets closer to the sensor.
For more information, see Using the Ultrasonic Sensor in the EV3
Software Help.

Detectable distance
NOTE:
Since the Ultrasonic Sensor
depends on reflection of the sound
waves it may be ineffective at detecting
surfaces that are textured or objects that
are rounded. It is also possible for
an object to be too small for the
Ultrasonic Sensor to detect it.

Infrared Sensor and Remote Infrared Beacon
The Infrared Sensor is a digital sensor that can detect infrared light
reflected from solid objects. It can also detect infrared light signals
sent from the Remote Infrared Beacon.
The Infrared Sensor can be used in three different modes: Proximity
Mode, Beacon Mode, and Remote Mode.
PROXIMITY MODE
In Proximity Mode, the Infrared Sensor uses the light waves reflected
back from an object to estimate the distance between the sensor
and that object. It reports the distance using values between 0 (very
close) to 100 (far away), not as a specific number of centimetres or
inches. The sensor can detect objects up to 70 cm away, depending
on the size and shape of the object.
For more information, see Using the Infrared Sensor Proximity Mode
in the EV3 Software Help.
BEACON MODE
Choose one of the Remote Infrared Beacon’s four channels from
the red Channel Selector. The Infrared Sensor will detect a beacon
signal matching the channel that you specify in your program up to
a distance of approximately 200 cm in the direction it is facing.
Once detected, the sensor can estimate the general direction
(heading) of and the distance (proximity) to the beacon. With this
information, you can program a robot to play hide-and-seek, using
the Remote Infrared Beacon as the target of its search. The heading
will be a value of between -25 and 25, with 0 indicating that the
beacon is directly in front of the Infrared Sensor. The proximity will
be values between 0 and 100.

in the EV3 Software Help.

The Remote Infrared Beacon is a separate device that can be
handheld or built into another LEGO
®
model. It requires two AAA
alkaline batteries. To turn the Remote Infrared Beacon on, press the
large Beacon Mode button on the top of the device. A green LED
Indicator will turn on, indicating the device is active and transmitting
continuously. Another press on the Beacon Mode button will turn it
off (after one hour of inactivity, the beacon will automatically turn
itself off).
REMOTE MODE
You can also use the Remote Infrared Beacon as a remote control
for your robot. When in Remote Mode, the Infrared Sensor can
detect which button (or combination of buttons) on the beacon is
pressed. There are a total of eleven possible button combinations:
 = No button (and Beacon Mode is off)
 = Button 1
 = Button 2
 = Button 3
 = Button 4
 = Both Button 1 and Button 3
 = Both Button 1 and Button 4
 = Both Button 2 and Button 3
 = Both Button 2 and Button 4
 = Beacon Mode is on
 = Both Button 1 and Button 2
 = Both Button 3 and Button 4

Temperature Sensor
The Temperature Sensor is a digital sensor that measures the
temperature at the tip of its metal probe. The sensor measures
in Celsius (-20°C to 120°C) and Fahrenheit (-4°F to 248°F) with an
accuracy of 0.1°C.
The Temperature Sensor is most commonly used to collect data for
heat-related data logging projects. With a 50 cm–long Connector
Cable and a 6.4 cm metal probe, the sensor makes it easy to
measure hot liquids away from the EV3 Brick and other electronics.
