Cozmo's Cubes, Spare Parts and Multiple Devices
Learn below everything you need to know about Cozmo's cubes.
Sections:
What battery does the cube use?
- Alkaline N / E90 / LR1 1.5 Volt batteries
- Do not use A23 batteries - these will damage the Cube
- Do not use rechargeable batteries - these will damage the Cube
How long does the battery last?
- 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:
- 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
- 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
How do I change the battery?
- 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)
How does Cozmo interact with his cubes?
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
Indicators of cubes not working correctly
- 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
Troubleshooting
- 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

Using Cozmo with multiple devices and cubes
A Single Cozmo and Multiple Devices
While it is absolutely possible to use more than 1 device with a single Cozmo, there are some things of which you need to be aware.
- Only 1 device at a time can connect to any single Cozmo. It is not possible to use 2 or more devices simultaneously with the Cozmo.
- When another device / player plays with Cozmo, progress earned and changes made to Cozmo stay with him. For example, someone else can spend all of the Sparks you had earned
So, when different people and their device connect to your Cozmo, the next time you connect you may notice changes to Cozmo that you did not experience with him.
For example:
- Changes to Cozmo's volume level.
- Different Tune Up and Feed Nurturing levels.
- You no longer have the same number of Sparks and Tokens.
- There are New People in Meet Cozmo.
- Cozmo needs to readjust to your skill levels in games.
- He may be too easy or too hard to beat in Quick Tap, Keepaway, or Memory Match.
You will be unable to re-earn:
- Bonus Boxes that contained new Songs, Games, or Abilities.
- Game Unlocks and Cozmo's skill levels.
A Single Device and Multiple Cozmos
You can absolutely use any device that has the Cozmo app with more than 1 Cozmo. Please note that any or all of the following can be different on each Cozmo:
- Cozmo's volume level
- Nurturing levels for Tune Up and Feed
- People in Meet Cozmo
- Number of Sparks and Tokens
- Available Songs, Games, and Abilities
- Game Unlocks and Cozmo's skill levels
Only Saved Cozmo Code Lab Projects will not change when you connect to different Cozmos.
Cozmo Code Lab Projects are unique to each device. If you delete the app from any device, all of the saved Code Lab Projects on that device will be lost. Once changed or deleted, Code Lab Projects cannot be recovered and there is currently no way to archive or share these Code Lab Projects. The Code Lab Projects that you create only exist on the device on which they were saved.
What about Cozmo and Multiple Sets of Cubes?
When Cozmo wakes, he always pairs with the 3 closest unique Cubes unless you have activated Education Mode and selected that Cozmo always use the same 3 cubes (see this FAQ) for more details).
- Three (3) unique Cubes make up a single Set of Cubes.
- A Set of Cubes consists of a #1 Cube, a #2 Cube and a #3 Cube.
- Cozmo cannot use more than 1 Set of Cubes (3 Cubes) at a time.
Here's a picture of a single Set of Cubes.
Here's a close up of how each Cube is numbered 1 through 3.
To Cozmo, every #1, #2, and #3 Cubes are the same as every other #1, #2, and #3 Cubes, but Cozmo can only ever sync and interact with one #1, one #2, and one #3 at the same time.
So, if you have 2 or more Cozmos that each came with their own set of Cubes, Cozmo will pair with the first three #1, #2, and #3 Cubes he reaches. Also, be careful because when you have more than 1 Set of Cubes near Cozmo, he may connect with one or more Cubes that you do not expect him to use.
If Cozmo is not using the correct Cubes, you can easily help Cozmo to swap/change to a different Set or individual Cubes with these steps:
- Identify which cubes Cozmo is synced to by going to Settings > Cube Status > Identify Cubes > tap a colour > all synced cubes will flash this colour until you tap "done"
- Place the new set of Cubes very close to Cozmo.
- In the Cozmo app, tap the Settings icon in the upper right corner.
- Scroll right until your reach the Cube Status.
- Tap the "Auto Connect to Cubes" button.
- Press the "Connect" button.
- The closest set of Cubes will glow green and the briefly blue when successfully paired.
Can one Cozmo interact with another Cozmo?
Cozmo does not recognize himself or his brethren and will not interact with them.
