Anki Cozmo Battery Replacement
Inleiding
Ga naar stap 1If your Anki Cozmo robot keeps turning off or the screen does not come on, follow this guide. This guide is to assist users replacing the battery in an Anki Cozmo robot, so it can come back to life. The battery, located inside Cozmo’s base, allows it to survive. Without a functioning battery, nothing else will work. Before beginning, make sure to power off your Anki Cozmo robot and disconnect it from the Anki Cozmo app.
WARNING: when using hands to remove any component, be careful not to cut yourself or rip your fingernail.

Remove the two black rubber treads from the wheels using your hands to pull them off.

Remove the white hubcap from each of the four wheels using the metal spudger to pry them off.
Note: The hubcaps are the same color of your Cozmo. My Cozmo is black to gray, but the one from the creator shows a white Cozmo.

Pry off the two white arms from the right side of the body and the two white arms from the left side of the body using two metal spudgers.
-
Pry off the arms by digging the tips of each spudger in between the arm and the body and pushing up away from the body.
Steps 9 and 10 contain errors that will lead to broken parts of the robot.
The upper arms (thin) must be pry off on both sides with metal spudgers. Then remove the white axis that connects them (what is called a spring here).
And then you need to manually rotate the lower arms to the upper position (while slightly pulling them) until the latches are aligned with the corresponding slots in the case and the arms separate from the body. No force required.
If you remove them with metal spudgers, you will leave marks on the case and break one or more of the latches.
YES this is the good method to avoid broken arm :

And then you need to manually rotate the lower arms to the upper position (while slightly pulling them) until the latches are aligned with the corresponding slots in the case and the arms separate from the body. No force required.

Step 9 should be operated while the arm is at his maximum height.
Yes, excellent tip!

Step 9 is the hardest from far ! And you'll easily get hurt by your tools. Moreover, reassembling cozmo will certainly deteriorate it. You should operate the big part of the arm (the lower) while the arm is at his maximum height. To do so, disassemble the white part of the fork by prying it down. Then remove the 2 screws of the upper arms, and remove these arms. Eventually, the big arm is easy to remove (or to reassemble).
Is it necessary to disconnect the screen? I am having trouble getting the little white connector pulled off and am wondering if I can just leave it connected
Its possible to carefully allow it to hang also.
This guide doesn't even mention soldering. Is it possible to replace the battery without soldering?
no its not posseboul
sorry for the bad english
I’m pretty sure I messed mine up. It turns on and everything is good after the battery replacement. But, now when I put it on the charger, the charger and the robot continuously flash and I don’t think it is charging. I may have messed something up on the soldering. Anyone have these symptoms after replacing the battery?
By the way, these instructions for disassembling and reassembling with the notes are spot on.
If battery is soldered on correctly should the Cozmo be able to power on before being reassembled?
I cut the cables of the old battery and attached a 620mah Battery Type 503040, 3,7Volt, Bye soldering. The 503040 is almost to big to fit in. You have to compress/bend the contacts one the Battery to fit but worked well.
