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
