Ozobot educational robot

Where can I find exercises and activities for my lessons/workshops?

We have gathered the best educational resources, classified by levels or by robots on our website. You can consult them via this link.


Is Ozobot compatible with Scratch?

No, but you can program your Ozobot with OzoBlockly, Google's equivalent to Scratch.


How long can Ozobot go with a single battery charge?

Ozobot can go for 90min on single charge. It takes 30-40min to fully chareg Ozobot. Not bad!


Do I have to use only the Ozobot markers?

No, you can use other markers provided that they can draw 6mm thick lines. The colours that the Ozobot can recognise are blue, red, green and black. You also have to be careful, the coloured lines can't be too dark or too light!


Are my Ozobot robots waterproof?

Ozobot is not waterproof. Please do not put robots in your mouth and never put them in liquids. Ozobot is an electronic product and not moisture resistant.


How to calibrate Ozobot?

Calibration is very important. As soon as you want to change the background or program the robot using a digital display, it has to be calibrated. Calibration adapts the optical bit sensors to the surface and the light environment. A detailed guide for calibrating Ozobot is enclosed.


Should I clean my Ozobot?

Ozobot is very small. A little dust, grease or crumbs can cause problems when driving. To clean Ozobot, simply follow these steps: take a clean sheet of white paper. Gently rub Ozobot back and forth over the paper. The wheels are clean again


Ozobot doesn't follow the lines anymore. Why is that?

1)Make sure the lines are wide enough. 2)Check the Ozobot calibration.
