Varikabo: Mini Robot Kit
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.
