Varikabo STEM Robotic Kit – Multifunctional Mini-Bot for Soldering – Set of 10 Robots

This box contains the parts to build 10 varikabo robots. They are not packed separately. Varikabo is an easy-to-build robot kit with a highly sensitive sensor system. You can explore twelve different functions and astounding behaviors using a selector switch and adjusting and exchanging the sensors. An exciting and playful start to learning electronics!

• 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

The patented combination of three light sensors allows Varikabo to react sensitively to its surroundings, recognizing objects, obstacles, light, shadows, and ground markings due to the slightest color tone contrast. Then, depending on the chosen function, Varikabo adjusts its direction and speed to match its environment. Varikabo’s “brain cells” are simply two transistors, making it even more amazing that it can do what it does.

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. Varikabo eye-LEDs show how he feels: They shine red if he’s in a hurry or on the run. They shine blue if he feels comfortable and stands still – for example, under your hand.

The Composition

The setup of varikabo takes about two hours. It would help if you had a soldering iron, solder, a 9 V battery, players, 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. The experiment manual explains the configuration of the various functions, showing how these can be set using the selector switch and the three exchangeable sensors.

Further, you’re shown how the control circuits are set up and how the various components function. As a result, you can learn to understand and comprehend Varikabo’s multifunctional behaviors and what causes them. This is a fun and practical way to learn the basics of electronics!

The Perfect Kit for Schools

varikabo is particularly well suited as an exciting introduction to electronics and robotics. The kit offers an interesting soldering project, a multifunctional robot, and a practice-oriented learning carrier. Since it is easy to put together, it ensures an immediate sense of success. At the same time, the fact that many construction options exist leaves plenty of room for creative experimentation.
