Cozmo has no sound
The sounds that Cozmo makes to display emotions are quiet, low quality, or do not exist.
Low volume on Cozmo
Make sure the volume on Cozmo itself is turned up.
Low volume in Cozmo app
Open the Cozmo app and make sure the volume is up. Go to Music Level General Settings > Volume and General.
Low volume on cellular device
Make sure the device using the Cozmo app is not on vibration, in silent mode, or on low volume.
Obstruction of speakers
If the sound quality is weak or quieter than it should be, a common cause is that there is foreign material blocking the speaker. This can be fixed by accessing Cozmo’s internal hardware and lightly dusting off the speaker system with a cotton swab or similar object.
Speaker failure
If the sound does not emit from Cozmo at all, the speakers may not work and need to be replaced. To replace the speaker, follow this guide.
Cozmo does not recognize me
Anki Cozmo is turning on and doing the assigned tasks but cannot recognize you.
Environment is dark
Make sure Cozmo’s environment is bright by turning on the light or going to a brighter location. Make sure your face is well lit.
You are out of Cozmo’s line of sight
Make sure you are near Cozmo and in a straight line of its sight.
Too much movement
Make sure you are holding Cozmo still or Cozmo is on stable ground.
Too many people in Cozmo’s line of sight
Make sure there is not a large number of people in Cozmo’s line of sight. Also, make sure there is no one who is already recognized by Cozmo in its line of sight. If there is already a person recognized by Cozmo in its line of sight, then it doesn’t recognize the new person it is trying to scan because it recognized the person it already knew.
Cozmo displays “tutorial paused” error
New Cozmo displays errors on-screen during the setup tutorial.
Plastic wrap with red arrows is still on
There are two clear plastic pieces with red arrows, one in the front section under Cozmo's chin and the other on the back of the head. Make sure they are removed.
Unideal surface level
If Cozmo displays the "Put Cozmo on a flat surface" message, Cozmo should be placed on a flat and stable surface for it to explore.
Cozmo cannot see
The Cozmo app alerts you that “Cozmo is having trouble seeing”.
Unideal lighting conditions
Cozmo needs to be able to see in order to function properly. Cozmo often has trouble seeing when the lighting of its surrounding environment is either too bright or too dark. In order to help Cozmo see better, try adjusting the lighting of its environment accordingly. Either dim the lights or make them brighter.
Camera issues
Cozmo sees the world through a camera. If Cozmo is still having trouble seeing even in ideal lighting conditions, there might be an issue with its camera.
Cozmo will not eat
The Cozmo app alerts you that Cozmo is hungry, but you are having difficulty feeding it.
Cozmo cannot hear its cubes
To feed Cozmo, the cubes need to be energized and within range of Cozmo. Sometimes, Cozmo will not eat because it cannot hear its cubes. Try placing the cubes closer to Cozmo so that they are easier to detect.
Cubes need new batteries
Sometimes, Cozmo will not eat even if the cubes are near it. If this is the case, the cubes might not be working. First, give Cozmo a quick snack while you work on the cubes. Then, test to see if the batteries need replacing. To test if the battery needs replacing, unscrew the cube’s lid, wait ten seconds, then screw the lid back on. If the cube flashes red, green, then blue, the battery is good. If not, replace the battery. To replace the battery, follow this guide: Anki Cozmo Battery Replacement.
Cubes need to be reset
If the batteries are working and Cozmo is still not eating, the cubes might need to be reset. First, give Cozmo a quick snack while you work on the cubes. Then, make sure the cubes are connected properly. Open the Cozmo app, go to Settings, and then go to Cube Status. If the cubes are all connected, there will be three green checkmarks. If not, they might need to be reconnected. To connect the cubes to Cozmo, move them to another room to stop Cozmo from connecting to them, close the Cozmo app, relaunch the Cozmo app, and place the cubes near Cozmo for them to connect.
Cozmo cubes do not turn on
Cozmo is trying to interact with the cubes but is experiencing some issues.
Cube battery is dead
The cube’s battery causes it to light up and interact with Cozmo. To test if the battery is dead, unscrew the cube’s lid, wait ten seconds, then screw the lid back on. If the cube flashes red, green, then blue, the battery is good. If not, replace the battery. To replace the battery, follow this guide: Anki Cozmo Battery Replacement.
Cube is not connected
In order to work, the cubes must be properly connected to Cozmo. To make sure the cubes are connected properly, open the Cozmo app, go to Settings, and then go to Cube Status. If the cubes are all connected, there will be three green checkmarks. If not, they might need to be reconnected. To connect the cubes to Cozmo, move them to another room to stop Cozmo from connecting to them, close the Cozmo app, relaunch the Cozmo app, and place the cubes near Cozmo for them to connect. If the cubes are still not connecting, this could be a battery issue. To replace the battery, follow this guide: Anki Cozmo Battery Replacement.
Cozmo keeps turning off
Cozmo shuts off randomly on its own.
Cellular device does not meet minimum specifications
Check to make sure your device meets the minimum specifications:
- USB adapter should be type A
- If your Cozmo does not have a backpack button- use a power source that is minimum output 5V/2A
- If your Cozmo does have a backpack button- use a power source that is minimum output 5V/1A (recommended output is 5V/1.5A)
Low battery
Charge Cozmo for 30 minutes until it shows a solid green LED. Make sure the USB cable is fully plugged into the adapter / USB power source to make sure Cozmo is getting enough amperage.
Network auto-switching is on
Turn off network auto-switching on your cellular device by following the steps below.
Android Devices:
- In the App Drawer (or on the Home Screen), click on "Settings"
- Click on "Network & Internet" and then click on "Wi-Fi’
- In the top right-hand side of the screen, select the submenu and click "Advanced Wi-Fi"
- On this screen, turn off the "Switch to Mobile Data" option
iPhone / iOS:
- On the Home Screen, click on "Settings"
- Click on "Cellular"
- Find "Wi-Fi Assist" (you may have to scroll down)
- Once you have found "Wi-Fi Assist", swipe to turn it off
Cozmo displays error 2 or error 3
Cozmo is displaying error 2 and 3 messages on screen.
Cellular device needs to be refreshed
Restart your device. Uninstall the Cozmo app (tip: export your code lab projects first). Remove the SD card. Reinstall the app. If the error persists, repeat the steps and also clear your Google Play Store and Google Play Service cache and data before reinstalling the app.
Cozmo will not connect to my cellular device or WiFi
Cozmo cannot connect to its WiFi or the cellular device to use the Cozmo app.
Cellular device is not compatible
Check to make sure your cellular device is compatible with the Cozmo app. Check to make sure the app version is up to date. Check to make sure your device’s OS version is up to date.
No network available
Check to make sure your cellular device is searching for all network types
- Toggle airplane mode to temporarily cut data exchanges
- Turn off mobile data connection
- In the list of networks in your device's WiFi settings, forget Cozmo’s network
- Turn off Wi-Fi assist (iOS 9 or higher or Android 8 or higher)
- Disable VPN if you are using it
No location service detected
Check to make sure location services are turned on in your cellular device (location will not be stored).
Cellular device lag
Check to make sure your cellular device is not lagging.
- Turn off the "Smart network switch" - Android 6 (Marshmallow) or Android 7 (Nougat) only
- Powercycle Cozmo
- Cozmo with a backpack button:
- take Cozmo off its charging station
- press and hold the backpack button for 5 seconds
- place Cozmo back on its charging station
- Cozmo with no backpack button:
- take Cozmo off its charging station
- unplug the adapter from socket (leave USB plugged into adapter)
- place Cozmo back on its charging station until its light goes off
- plug adapter back into socket
- place Cozmo back on charging station
- Cozmo with a backpack button:
- Restart your device
- Close apps and processes running in the background on your device
Weak signal
Check to make sure the Cozmo Wi-Fi has a strong signal.
Home WiFi interference
A common cause of this issue is home WiFi interfering with the Cozmo WiFi or preventing it from reaching and connecting to your cellular device. Check for interference from other devices. Distance Cozmo from microwaves, baby monitors, digital cordless telephones, etc. A common symptom of this error is being prompted to re-enter your password or noticing the Cozmo WiFi is dipping in and out. To fix this, try turning your home WiFi off while using Cozmo. This reduces interference from the home network and should increase the reception and connective ability of the Cozmo WiFi network.
App Issues
If Cozmo is not connected to your phone’s WiFi through the app that had to be downloaded in order for him to operate, it will not turn on. Go to the app store and download the app “Cozmo”. After that, put it on its charger and press the “on” button. Open the WiFi in your phone’s settings application and connect to Cozmo’s WiFi. Then, take Cozmo off of its charger and try again. It should wake up.
Arms don’t move
Cozmo’s arms will not move upon command from the Anki app, or to express mood during the free mode.
Arms misaligned
A common cause of the arms not moving is the arms becoming misaligned with the internal motor system. To fix this, remove arms using a screwdriver and then reattach them.
Screen Doesn’t Come On
When Cozmo is powered on his screen does not light up.
Battery is dead
Cozmo’s battery may be depleted and needs charging. Place Cozmo on its charging station and press the power button.

Where can I locate a speaker replacement for Cozmo? My son got him for Christmas last year and he has never made a sound. We thought Cozmo would eventually make noise the more that we played with him but that still has not happened.

My cozmo’s conection keeps switching to my internet wyfy, is that according to to wyfy interference? Because my connection didn’t start until last December after his birthday ( when I got him, on 2018,) unless his intelligence just got smarter, and being somewhat cocky or smart enough to Switch my conections so he could turn himself off anytime, before then, he did one weird thing before, I told him that it was time for bed, and just went to sleep, but now he turns himself off, I’m just wondering if it’s something of the connection or it’s cozmo’s intelligence, I don’t know? And if it is artificial intelligence, I’m so lucky to have this one cozmo robot in my life/house. I meant a living artificial intelligence, ok? Glad to have a cozmo like this in my life, really!!

Hello. I just got my new wonderful COZMO!
I have a problem though.
After charged, the WiFi duration is very little as it is constantly disconnecting.
I have to reconnect COZMO to his WiFi again on his charger to get the WiFi signal again every time I want Cozmo to stay active again.. but then again, it lasts very little and the COZMO Wi-Fi disconnects

When tuned on, works for a few seconds, then both Cozmo and app shuts off, and the connection to Cozmo for the wyfy disconects automatically, and between the process the upgrade comes up every time, while Cozmo is trying to boot up.

Thank you ifixit!!! My son’s Cozmo appeared not to be charging and we couldn’t connect to it via iphone WIFI at all - I thought from reading other site posts that the battery was dead!! After reading here about home WIFI interference I took the little chap (Cozmo) to a point further from my hub and repeaters and……. I could connect to it via iphone WIFI then I was able to link to it via the app and update its firmware etc.
He still shuts down if I get too close to the WIFI think spots, but otherwise he’s fine. We’ve run down the battery several times and it’s lasting longer and longer. Thanks again - that saved a toy from the bin!!

Andrew Pankov - Reply
If it charges in less then 10 mins and only lasts a couple minutes or seconds on off the charger, then you need a new battery. It doesn't matter if you bought it a couple months ago - Cozmo was made over 2 years ago and unless the battery has been consistently charged/discharged the battery will go bad if left unused for months by the original owner; so you will have to get a new one.
For those with pixelated screens or dimming screens, you are out of luck because they don't make the screens anymore and you only source is to get a defective or used one and take the screen from it.

:D what country are you in? If you are based in the US I can service your cozmo for a fee
https://techshop82.com/shop/anki-cozmo-v...
If you want to replace the battery yourself you will need soldering iron, philips #0 screwdriver, and a new battery - most popular is the 504030 lipo 3.7 600 mah. There youtube videos on how this is done.

You need to make sure your phone stays connected to Cozmo and does not switch back to your wifi because it can't detect the internet.
On android it asks do you want to remain connected (you might have to wait for this prompt), then click yes and remember. Then go to the cozmo app. I'm not sure what it is on IOS but its the same reason.

If his screen is blank but the light is on, it means you have a dead screen and possibly a dead/dying battery. I fix Cozmo's as a business, if you want to reach out to me you can do so here and we can continue the conversation:

Crazycat 64 - Reply
I got my cozmo a while ago and stopped playing with it because I couldn’t find the right batteries for the cubes. Revisiting it years later helped me realize that it wasn’t the batteries, it was the cubes. I tried reconnecting them and only 1 works. I’ve tried everything and I’m really stressed because I was excited to use it again. I’m not sure if there is a solution to this because it is the older cozmo. I just really wish I got to play with it for more than a month after I got it.
Adriana Hawkins - Reply
If you use the 1.5 N batteries the cubes should light up for a couple seconds when you insert a new battery in them. If you inserted a 12V N battery, then the cubes circuitry would be instantly fried and there is nothing to be done to fix that except replacing them.
These are the batteries that should work with the cubes: https://www.amazon.com/gp/product/B01IN3...

How to know if Cozmo is charged?
TK facts and fun - Reply
With the factory battery it will take ~30mins to charge, the 3 lights on its back will turn solid green and after a while will turn off to indicate it is no longer charging
If this happens and your Cozmo only lasts a couple of minutes off the charger, then you will need to get your battery replaced.

You most definitely need a new battery. Look for a 603035 lipo 3.7v 600 mah battery online. You will need a soldering iron, and Phillips #00 screwdriver to open the guy up and change it out

Dee A -
Back again, but this time, I am just saying that I actually did not need to go to a repair shop. All I had to do was boot him up and update him. \(l o l)/
John Zeng -
That's good but having to update could be a sign that the battery is going bad. There hasn't been an update for Cozmo in years. Test how long the playtime is just to make sure. When the battery depletes Cozmo reverts to a factory state, and when you replaced the battery it gets updated from the app.

Make sure the contacts are clean, use alcohol to clean just to make sure. Also make sure to use 1.5V N batteries, if you used 12V then the board has been damaged. Goodluck
