Introduction
Edison is your new robot buddy who will teach you about electronics, programing and
robotics in a fun and engaging way.
He’s equipped with all the sensors, outputs and motors needed to introduce you to the
amazing world of robotics.
That’s great, but what is robotics? Well
that’s not an easy question to answer.
Edison’s creator, Brenton O’Brien says “a
robot is a machine that can behave
autonomously” . This means that a robot
can think or make decisions on its own
and act on those decisions. Many other
people have different definitions, but we
like this one as it’s nice, simple and
applies to what you’re about to learn.
Robotics wouldn’t be possible without electronics, so Edison has his own electronics and
you can see it all through his transparent top. There are resistors, capacitors, transistors,
motors and more, but the most important electronic part is Edison’s microcontroller.
The microcontroller is like Edison’s brain. It’s where all
his ‘thinking’ happens. Edison’s microcontroller is very
similar to the processor chip inside a computer, only
much smaller. And just like a processor chip in a
computer, Edison’s microcontroller has programs. The
programs allow Edison to make decisions and ‘think’ for
himself.
Edison comes with pre-loaded programs that are activated by driving over special
barcodes. Here is a sample barcode that activates Edison’s line tracking program.

Getting started
Let’s get Edison ready to go!
Open the battery compartment and
remove the programming cable. Now
insert 4 ‘AAA’ batteries. Refer to the
image to ensure that the batteries are
the correct way around and clip the
battery cover on.
If you haven’t already done so, stretch
the tyres over the wheels.
Turn Edison on by sliding the power
switch to the on position. Edison’s
red LED lights will now start
flashing.
Edison is ready to go!
Ensure the batteries are the right way
Push the switch towards the on symbol
Get to know Edison
To use Edison you’re going to need to know where all his sensors are and what his three
buttons do. Have a look at the images below. You may need to come back and have
another look as we go through the EdVentures.
Play button –Start program
Stop button –Press to stop a program
Record button –1 press = download program, 3 presses = read barcode
Edison’s line tracking sensor is made up
of two parts a red LED light and a light
sensor. The red LED shines light on the
ground, if the ground is white and
therefore, reflects light then the light
sensor will get a high light reading. If the
ground is black and therefore, does not
reflect light then the light sensor gets a
low light reading.
The EdComm cable is used to download
programs to Edison. It connects into the
headphone socket on your computer or tablet.

EdVenture 1 –Clap controlled driving
Edison is equipped with a sound sensor and can detect loud sounds like clapping.
This barcode activates Edison’s ‘Clap controlled driving’ program. The program listens for
a loud sound like a clap and Edison responds by turning to his right. If you clap twice he
drives forward and stops.
Reading the barcode
1. Place Edison facing the barcode on the right side
2. Press the record (round) button 3 times
3. Edison will drive forward and scan the barcode
What to do
Place Edison down on a flat surface and
press the play (triangle) button.
Now clap your hands close to Edison. He
will turn to his right. Now clap your hands
twice and Edison will drive forward about
30cm.
Also, try tapping Edison with your finger,
once and then twice.
EdFact
Sound sensors just like the one in your Edison are used in modern cars to detect when the
engine fires each cylinder. This information is fed to the car’s computer to ensure that the
firing is occurring at just the right time. If the engine is firing too late it can cause damage
to the engine. Ensuring that the firing is happening at just the right time also ensures the
most economical fuel consumption.

EdVenture 2 –Avoid obstacles
Edison can see in the ‘dark’ using invisible light to detect obstacles and avoid collisions.
This barcode activates Edison’s ‘Avoid obstacles’ program. The program drives Edison
forward, when an obstacle is detected he reverses and then turns on the spot away from
the obstacle, then continues to drive.
Reading the barcode
1. Place Edison facing the barcode on the right side
2. Press the record (round) button 3 times
3. Edison will drive forward and scan the barcode
What to do
Assemble some obstacles for Edison to
avoid, such as walls made from LEGO. The
obstacles need to be at least the same
height as Edison (3.5cm/1.5in).
You could even build a maze for him to
escape from.
Press the play (triangle) button and watch
Edison approach an obstacle and then turn
away to avoid colliding with it.
EdFact
Edison’s obstacle detection system uses the same invisible light that your remote control
uses to tell the TV to change channel. This light is called ‘infrared’ or ‘IR’ and is invisible
because it has a longer wavelength than the human eye can see.
Edison emits IR from two light emitting diodes (LEDs), one on the left and one on the right.
In between the two LEDs is an IR sensor. The sensor detects when IR is reflected from an
obstacle. If the IR is reflected from the left LED then the obstacle is on the left. If the IR is
reflected from the right LED, then the obstacle is on the right.
Is Edison not behaving? Does he bump into obstacles or does he jump at shadows? Go to
page 14 to see how to calibrate his obstacle detection system.

EdVenture 3 –Follow torch
Edison loves light! He will drive towards the brightest light source even if it means falling
off the table. Such is love!
This barcode activates Edison’s light following program. The program uses Edison’s light
sensors and motors to follow a torch (American English: flashlight).
Reading the barcode
1. Place Edison facing the barcode on the right side
2. Press the record (round) button 3 times
3. Edison will drive forward and scan the barcode
What to do
You will need a torch/flashlight and a flat
surface away from any really bright light,
such as sun light.
Press the play (triangle) button and aim the
torch at Edison. Once he ‘sees’ the bright
source of light he will drive towards it.
By moving the torch you can control where
Edison drives to. Does this behaviour
remind you of anything?
EdFact
This is one of Edison’s most interesting programs, because it mimics the behaviour we see
in some flying insect. I’m sure you’ve seen moths on a hot summer night swarming around
a bright light. This type of robotic behaviour is called ‘phototropism’ and is normally found
in plants that grow towards the sun.
This program is also very interesting, because Edison is behaving autonomously. This
means that he is thinking for himself and responding to changes in his environment.
Is he alive?

EdVenture 4 –Line tracking
Meet the holy grail of enthusiast robotics; line tracking. Line tracking is a very popular
robotics activity as it’s fun to watch the robot go around and around a track. See how many
people ask you “Is that line magnetic?”
This barcode activates Edison’s line tracking program. The program uses Edison’s line
tracking sensor and motors to follow the edge of a black line.
Reading the barcode
1. Place Edison facing the barcode on the right side
2. Press the record (round) button 3 times
3. Edison will drive forward and scan the barcode
What to do
The first thing you need is a line. You can
print the small track on the next page, print
the large A1 (84cm x 59cm) EdMat from
meetedison.com/downloads or make your
own using black electrical tape on a white
table (the line must be 1.5cm/0.6in thick).
Place Edison to one side of your line, so that
the line tracking sensor is on white. Now
press the play (triangle) button and watch
Edison follow the line.
EdFact
Edison’s line tracking sensor shines light on the surface and then measures the amount of
light that is reflected back. White reflects a lot of light, giving a high light reading and black
reflects very little, giving a low light reading.
To track the line Edison is in a constant state of dissatisfaction. When he is off the line, he
turns right to get on the line. But when he’s on the line, he turns left to get off the line. This
results in him waddling on the edge of the line.
