 EV3 is the third platform Lego® has created for
robotics
 Platform 2: NXT can still be used but is no
longer supported by Lego, however it can still
be programmed using the EV3 Mindstorms
software
 Two parts to all robotics; Construction (what
do you want your robot to do) and
Programming (how will your robot do it?)

Robotics promotes and/or supports
 Mathematics - angles
- problem solving
-algebra
-chance and data
 Science - simple machines
- force and motion
 Digital Technologies – Creative thinking

 Whilst allowing students to create a robot is
fun , engaging and interesting, you will get a
multitude of designs that may or may not meet
the intended purpose. When starting out use a
simple design for all students/groups, the
activity will have more purpose and run a lot
smoother.
 For this reason today we are using the basic
design you have prebuilt to allow more hands-
on time

1. Open LEGO
Mindstorms
2. Click the “+”
icon to open a
project tab
3. Rename your
program

Working in the program is simply click,
drag and drop.
Programming is icon based.
Icons are located at the bottom of the
program window.
Each icon will change once it has been
placed to give a number of variables
associated with the that icon eg. power,
volume, distance.
You can collapse or
expand the
“Document your
work” dialogue box
by clicking on the
Mindstorms logo next
to the pencil.

 Connect the robot to the computer via USB
cable
 Click this button
 Wait for confirmation beep
 Disconnect cable and run program

Click and drag a “Large Motor” icon to the programming pallet,
placing it next to the “Play” building piece. The icon will change to
look like the one below. The functions for the motor are all shown on
the icon with drop down menus.

Use Trial and Error make your robot turn 180o
Does wheel rotation
equal robot rotation?

Program your robot to
1. Travel forwards 5 rotations
2. Travel backwards 3 rotations
3. Complete a sharp right-hand turn
4. Complete a slow left-hand turn
5. Travel forward 3 seconds and then backwards
for 2 seconds
6. Turn exactly 90o

“Wait for Time” Allows the
robot/program to complete one task
before moving to the next or by
defining a delayed start time for an
action.

Challenge:
Program your robot to greet someone as they walk past

On the floor are a cup-ple (please laugh). Your robot must
complete a figure 8 around the cups.
