The multifunctional Mini-Bot for soldering


By using a selector switch and adjusting and exchanging the sensors, you get to explore twelve different functions and astounding behaviors.

  • masters obstacle courses
  • follows dark and light lines
  • chases or pushes objects
  • searches, tracks or circles under light
  • tracks or circles under shadows
  • circles on dark or light areas

A small Robot with astounding  Possibilities

With the help of a clever combination of brightness sensors, varikabo can pick up the tiniest contrasts in his surroundings and react to them in various ways.

The two outer sensors determine the direction and the middle sensor the speed. You can take off the left and right sensors and exchange them. They determine whether varikabo will seek darkness or light.

The three rotatable brightness sensors cause him to respond to lines, objects, light, and shadows. By adjusting the sensors downward, upward, and forward, you decide whether varikabo will respond to these when they're on the ground, in front of him, or over him.

With the switch, you choose the acceleration or brake mode. varikabos eye-LEDs show you how he feels: If he’s in a hurry or on the run, they shine red. If he feels comfortable and stands still - for example, under your hand, then they shine blue. 

varikabo offer long-lasting fun and variation!

How varikabo works

In the manual you're shown how the control circuits are set up and how the various components function. You can learn to understand and comprehend varikabo's multi-functional behaviors and what causes them.

This is a fun and practical way to learn the basics of electronics!
