CALIBRATION

Set your screen brightness to 100% and make sure the auto-brightness 

feature is turned off on your tablet or computer screens.

Place Ozobot against a white section of the screen (i.e. the 

flash loading spot in OzoBlockly) and release the button. 

Ozobot will begin flashing white.

When Ozobot blinks green, it means that it has 

successfully calibrated.  Start over if Ozobot blinks red.

X

Hold down the power button 
on Ozobot for 2 seconds.  

The Ozobot will flash a white 

light when ready.

It is important to calibrate Ozobot before each session 

and/or when you change play surfaces. Calibration helps 

improve Ozobot’s code and line reading accuracy.

CALIBRATION

Hold down the power button on Ozobot for 2 

seconds until the top LED light flashes white.

Quickly place Ozobot in the middle of 

the black calibration dot and let go.

Use a black dot slightly 
bigger than Ozobot to 
calibrate.  If you are 
using markers, create a 
similar sized calibration 
dot using a black marker.

If calibration is successful, Ozobot will move and 

then blink green. Start over if Ozobot blinks red.
