[1] STARTING FROM SAMPLE PROGRAMS
Various sample programs are included in IconWorks so that you can master
the concept of programming quickly. There are even programs with which
you can make the robot move without knowing any basic programming, so it
is possible for you to learn how to program by actually moving the robot.
For a detailed explanation for each icon and program transfer, please refer to
“USER’S MANUAL I, ALPHABET OF KIROBO”.
First of all, let’s open a sample program, transfer it, and move the robot!
* For detailed explanation for program transfer, please refer to Page 27 “Program Transfer” of “USER’S MANUAL I,
ALPHABET OF KIROBO”.
Some sample programs require modifications to be made to the robot assembly. Please read the manual carefully and
apply the modifications before sending or executing the program.
■ There are 5 topics covered by the sample programs.

[4] STEP-2 USING TOUCH SENSORS
By using the touch sensors we can learn about making conditional judgment programs. First, let’s practice the use of touch
sensors with a simple program which alters how the robot should move when Touch sensor1 is activated.
Step 2-1
Using touch sensors
KIROBO goes backward for 1 second when Touch sensor1

Change the locations of Touch sensor1 and 2 or “FORWARD” and “BACKWARD”, and see how the
robot movement changes.
Touch
In addition, remove "LOOP"
and "LOOP END"
, then send and execute the program.
How did the robot move?
The program is executed and ends very quickly. The forward movement remains ON because
there is no instruction to BRAKE or MOTOR OFF. Also because the program has ended (even
though the robot is still moving) pressing the touch sensor has no effect.
Turn the robot on and off and then run the program again but keep the touch sensor pressed as
you start the execution. What happens now?
To have the robot keep checking the status of the touch sensor and making a decision, the
program needs to be inserted in between "LOOP"
between "LOOP"
and "LOOP END"
and "LOOP END"
. The program
will be repeated over and over once the START button
is pressed.
Remove icons and put them back, and see how the movement
changes.

[5] STEP-3 USING LIGHT SENSORS

Using light sensors
KIROBO has Light sensors installed and will make a sound
when it gets dark.
Robot modification:
Not required
Let’s try a program using Light sensors and the “BRANCH” icon.

You should also practice adjusting the sensitivity of the sensor.

<How to adjust the Light sensor>
The sensor sensitivity needs to be adjusted according to the light in the current surroundings.
Turn VR1 or VR2 on the motherboard carefully with a +screwdriver to adjust the
sensitivity.
The LED below turns ON when the sensor detects the light.
[Not sensing]
[Sensing]
[Adjust sensitivity]
Send this sample program to the robot, and execute the program.
Cover the Light sensor with a finger as shown below and check if the Light sensor reacts or not.
If no sound is emitted, adjust the sensitivity again and re-check whether the sensor is detecting the light or not.
No reaction when Light sensor1 detects light.
A sound is made when Light sensor1 is covered with a finger.

Step 3-2
Using light sensors
KIROBO goes forward when Light sensor senses the light.
Robot modification:
Required
Preparation: Modify the robot as shown below.
Use C set [6], screw x 2pcs, and nut x 2pcs, and mount 2 Light
sensors at the front of the robot. Make sure not to switch the
positions of the 2 sensors when setting them at the front.
C set [6]
Set them as shown above.
Preparation2: Prepare something that emits light.
Ex) Flashlight, Infrared ball (RCJ-04), etc
A program using Light sensors and “BRANCH” icons.
The basic idea for the program is the same as in Step 3-1.
Learn how to adjust the Light sensors when the sensors are
mounted to the front of the robot.
When you finish the robot modification, open the sample
program and send it to the robot.
Prepare a light source, such as a flashlight, and execute the
program. (Refer to the photos below.)
Put the light in front of the

The robot can follow the
light of an infrared ball.
Although invisible to
human eyes, the robot
can see the infrared light.

[6] STEP-4 USING VARIABLES
For a detailed explanation of variables, refer to Page 46 of the “USER’S MANUAL I, ALPHABET OF KIROBO”.
Using variables
KIROBO makes a buzzer sound 4 when Touch sensor1 is
pressed and makes a buzzer sound 1 when pressed more

Touch sensor1 is pressed for more than 2 seconds.

<Practice>
(1) Change the condition for branching by variables.
(2) Change the variable calculation value and see how the behaviour changes.
Using variables
Step 4-2
This sample program is the modified version of the program in Step 4-1. KIROBO waits
until Touch sensor1 turns OFF. The count does not go on even when Touch sensor1 is
kept pressed.
One more condition is added to Step 4-1.
See how the behaviour changes.
At this point, the program does not proceed until Touch sensor1
is released. When released (Touch (1) changes to “NO”), it then
proceeds to the next step.
