I decided to share my experiences with repairing Emo Jo and Emo Ty.
First, I repaired Emo Jo. I replaced his four-leg servos and wires.
I eventually repaired Emo Ty.
However, Emo Ty continued to have issues after his first repair, so I had to repair him again.
Emo Jo and Emo Ty are now completely healthy and have no problems.
