Product code
OZO-50001BKM
Do you enjoy sending the Ozobot on funny and tricky paths that you draw on paper? Thanks to an extra set of black washable markers, you can draw whatever comes to mind - perhaps an Ozobot football field, a city where Ozobots meet, or even a labyrinth.

The markers are designed for both the Ozobot EVO and BIT+, and the width of their footprint is matched directly to their sensors. This helps Ozobots better navigate your routes and turns and doesn't require frequent calibration.

In the package, you will find 4 large black markers for drawing lines to guide the Ozobots to the color codes. In addition to the lines, you'll also easily create quick calibration points so you can fully focus on the fun gameplay and challenges of drawing command codes.

Enjoy creative programming to the max

Are you already a master of programming on paper? Then stock up on markers to easily draw paths for your Ozobot. The pack contains 4 black, non-toxic markers. Their width and yield are precisely matched to the sensors of both Evo / Bit+ models. The chisel tip, when held correctly, will create an easy-to-read 5mm wide track for Ozobot to follow seamlessly when programming. Stickers with colored ozocodes can be applied to the black lines, or the codes can be drawn behind the black line. The robot will unerringly execute the command you enter to read them. For example, you can make it dance, put it into turbo speed, or make it run backward!

Make playing and learning even more fun

Ozobot responds correctly to commands when its light sensors are calibrated for the substrate currently in use. With the help of markers, you can create a calibration point within close range of the game area each time! You can easily wash marker marks off your skin with soap and warm water. Wash clothes soiled with them immediately in warm water with mild detergent (no prewashing or bleaching). Keep them out of contact with porous materials such as wood, PVC, etc.

Tips for drawing codes

To keep Ozobot whizzing along the track without a hitch, it's a good idea to follow a few rules when drawing lines and codes. Use only plain white paper. Draw black lines without breaks. Colored ozocodes should be connected to them without gaps and should be placed only on the straight lines of your route so that the robot can read them with maximum accuracy. If you want to change the color code, it is best to relabel it with a new one. Don't be afraid to liven up your original track with all sorts of curves or crosses! Just don't make turns and bends at sharp angles, and remember that at an intersection with no preceding ozocode, the bot will decide which way to go. Let's see, which one of you can draw him a crazier adventure?

    In 2012, Ozobot came up with a new small robot prototype, and after 2 years of development, the robot was presented at the largest consumer electronics fair in Las Vegas. In the next years, children and students all over the world quickly took a liking to it. Since then, the Ozobot company has been making fun programmable robots for the next generation.

    The mission of Ozobots is to inspire young people to develop new technologies, instead of passively using them. Currently, the entire Ozobot concept perfectly fulfills the principles of STEAM education – linking polytechnic fields and a creative approach to developing a sustainable future.
