The variable MiniBot for soldering


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.

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

  • follow and avoid lines
  • circle in and follow light
  • circle in, follow, and avoid shadows
  • push, follow, and avoid objects

A small Robot with astounding  Possibilities

With the switch, you choose the acceleration or brake mode. The two outer sensors determine the direction and the middle sensor the speed. 

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!

The Setup

The setup of varikabo takes about two hours. You need a soldering iron, solder, a 9 V battery, plyers and a wire cutter. From the soldering process to the initial start-up, all of the necessary steps are included in the assembly instructions, accompanied by numerous illustrations. For these illustrations an elaborate 3D-CAD-model of the robot was designed.
