No, but you can program your Ozobot with OzoBlockly, Google's equivalent to Scratch.
Ozobot can go for 90min on single charge. It takes 30-40min to fully chareg Ozobot. Not bad!
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!
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.
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.
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
1)Make sure the lines are wide enough. 2)Check the Ozobot calibration.
