I received the new servos and replaced the damaged ones and now MiniEric works properly. I also changed some parts so now he is able to pick up small objects and I’ve programmed some moves and a sample melody that he can play.

I intend to write some random triggers to make it more interesting.
Here is a movie demonstrating these moves and sounds:
