Hello, @ethanreason . . . I have moved your new topic to this thread for issues like yours.
Do you still have the contact information for the Marketplace seller? Can they give you the order number they had when they purchased EMO? Sometimes you can transfer the information in these cases and then Support would likely be able to help you. He may only need recalibration or he may need new servos and wires. Until someone can have a look at him, you will not know for sure if he needs repair or not.
See if you can get the information from the seller.
Also, as far as repairs go, there are tutorials on how to repair him if it comes to that here.
You could attempt the repair yourself or if you know someone that is adept at this type of work, the information you need to do this would be here. If you send Support that four digit alphanumeric I.D. (shows in the app when you connect), they might be able to identify which parts he would need.
See first if you can get the information about your adopted EMO and contact service@living.ai with either the original order number or I.D. and a link to a video showing how he is walking.
Let us know how it goes.
