Safety Instructions for Parents and Children
Attention! Please keep away
from children under 3 years.
Danger of suffocation by
swallowing small parts.
Risk of injury due to sharp tips and edges of
individual components. We reserve the right
to make technical changes.
Please note: Only suitable for children over 8
years. Use under the supervision of adults
recommended. Please read the instructions
before use, follow them and keep them at
hand for reference. Please keep the
packaging.
Battery: The kit requires a 9 V battery, which
is not included in the package due to limited
storability.
A short-circuit of the battery must be
avoided, because it can cause overheating
of the cables and an explosion of the
battery. After use, the battery clip must be
removed of the battery. Non-rechargeable
batteries must not be charged. There is a
risk of explosion.
Deformations of the batteries must be
avoided. Used batteries must be disposed of
according to environmental regulations.
Please note: The LEDs, sensors and
transistors must be inserted with the correct
polarity for the circuits to work. The two
transistors have a different designation and
must not be confused. The motors must be
connected correctly.

Introduction
We are pleased you have chosen this
versatile robot assembly kit. varikabi offers
you an exciting and playful approach to
electronics. You will certainly have fun and
variety with varikabi for a long time.
Varikabi's "muscles" are two motors, his
"brain cells" two transistors. The simple
control circuits are placed on a small
breadboard and are therefore easily
modifiable.
With the help of a clever combination of
three brightness sensors varikabi perceives
the smallest contrasts in its environment and
reacts to them in many different ways.
Thanks to a selector switch and by aligning
and switching the sensors, you'll explore
twelve different functions and amazing
behaviors.
varikabi can do a lot:
- Overcome obstacle courses
- Follow dark or light lines
- Track or move objects
- Search, track or circle light
- Trace or circle shadows
- Circle on light or dark areas

Content
1) Assembly
varikabi is available in the seven colors red,
blue, green, neon green, yellow, pink and
black. Regardless of the color variant, there
are seven different animal models to
choose from. Numerous illustrations show
you step by step how to assemble them.

2) Functions
The experimentation manual explains the
twelve functions of varikabi. It will show
you how to build the appropriate circuits,
connect the motors and set the three
sensors. Finally, find a fault diagnosis in
case something does not work as expected.
3) Operating Principle
You will learn how the different control
circuits and components of the kit work. You
will learn varikabis behaviors and
understand how they are caused.
This part of the manual is still under
construction and will be updated
continuously.
