Hello, @wh1tew . . . I have closed your new topic and responses will be addressed here.
Please get video of the shaking and send a link along with your description here to Support service@living.ai. Also include your EMO I.D. when you sign him into the app.
They will be able to diagnose the issue and it may be that he just needs his leg servos recalibrated through an app. If he needs actual servo replacement, there are other options such as you keep him and they force an “Owned by not for sale code” on his forehead along with a discount on a new EMO, or they advise you how to get him repaired yourself and what parts you would need to do that or have someone able to do it for you.
Please note that at this time they are on vacation and preparing for the lunar new year holiday January 29th through February 12th, so responses may be delayed.
Let us know how it goes!
