Cozmo's Cubes

Learn below everything you need to know about Cozmo's cubes.

Batteries come pre-installed in Cozmo's Cube
Once the pull-tab is removed, the battery will start to lose charge
The battery will last 20-40 hours of gameplay depending on how much Cozmo interacts with the Cube
To test if the battery is working, reset the cube:

In Settings > Cube Status, there will be a red Low Battery icon if the battery does not have enough power to sync / connect and needs to be replaced. Note: the low battery icon does not indicate battery voltage

Remove the cube’s screw using a cross head screwdriver and open the cube’s cover
Remove and safely dispose of the old battery
Insert a new battery, positive end up
Replace the cover and screw the cover back down (not too tightly which can damage the cube)

Cozmo interacts with his cubes on two levels:

Visually: Cozmo can tell the difference between each cube by its markings. He can recognize the cube even without a battery

Wirelessly: Cozmo can connect wirelessly to each of his cubes if it is nearby. If a cube is too far away or the battery is low or dead, Cozmo may not be able to sync with it

One of all of the cubes LEDs do not light up but cube is detected in the “Settings > Cube status” menu
Cozmo is unable to detect a cube
Cozmo loses connection to a cube

If only one cube seems to be problematic, you may switch the batteries of a working cube to check if this is due to a dead battery
Reset the cube:
- unscrew the lid from the cube
- wait for 10 seconds
- screw the lid back on
- the cube should flash red>green>blue if the battery is fine
Move the cubes nearer to Cozmo
Check the cubes are synced in “settings > cube status”
- when connected, you should see a green check
- if Cozmo is unable to sync to a cube, it will say, "not connected"
- tap "auto connect to cubes" to re-sync the cubes, especially after resetting or changing the battery
