SENSORS
Sensors are what allow a robot to
gather information about its
environment. This information can
be used o guide the robots behavior.

ULTRASONIC SENSOR
Is used to measure distance using sound to measure the
time between when a signal is sent and when its echo
received back.

COLOR/ LIGHT SENSOR
Is used to detect color or the intensity of light

GYROSCOPE SENSOR
Detects rotational motion on a single axis

TOUCH SENSOR
It is used to detect physical contact between objects. It
also acts as an on and off switch to trigger a command.

INFRARED SENSOR
Works just like an ultrasonic sensor. It is also used to
measure distances.

MOTORS
• Are used for wheels to make robots move form one
place or another. Motors are also needed to drive
flaps , propellers or to simply control the opening or
closing of gripper.

EV3 LARGE MOTOR
The large motor is a strong and powerful motor.

EV3 Medium Motor
The medium motor is a less powerful motor but runs at
a higher revolution rate.

COMPONENTS

BEAM
A horizontal bar that is used to carry vertical load.
It is a major component in building bridges and other
structures which carry vertical loads.
Angle Beam- it can be used for lifting objects in
designing a robot arm.

PINS
Pins are in different length and tightness- the light grey
ones will orotate in the holes.

AXLE and ANGLE connectors
Axles are primarily used for connecting wheels.
With angle connectors, light frameworks can also be
built.

Gears and drive Trains
Gears are designated by the number of teeth.

Worms Gear, Bevel Gears and
Pulleys
• Worm gear with gear neck rack-equivalent of 1st
gear
High Torque
Difficult to back drive
Crown And Bevel Gears- Use to change angle of
rotation
Pulleys- Bridge distance

LEGO Wheels
• Avoid tracks
• Low friction/ high slippage
• Motion/ turns not easily reproducible

Large wheels go farther per
revolution
• Friction varies with different tires
• Support From both sides is best

Wheel-axle support
More support-less wiggle/sag
Support from both sides is best

PROJECTS VS. PROGRAMS
• You will start by creating a PROJECT which has a .ev3 extension. You change the name of a
project by using the Save Project As option from the File menu.
• You will write many PROGRAMS as part of each PROJECT file. You change the name of a
program within a project by doubling clicking on the program’s tab and typing in a new name.
• Note: If there is an * next to the project name, you have made changes to the project and you
have not yet saved yet.
• There is a “x” next to project and program names. Clicking on it simply closes the file (it does not
get deleted).
• Here are some common file extensions in the EV3:
• Programs (.ev3p)
• Images (.rgf)
• Sounds (.rsf)
• Text (.rtf)
• Projects (.ev3) – the only type of file you can open with the EV3 software
• Import file (.ev3s) – can be imported by an EV3 project 26
