Also to add, when you do pat EMO, try not to press down too hard as that could cause a problem with EMO always thinking he is constantly being petted.
As per the links that @edward shared. This one doe show that the patting sensor on EMO’s head uses a pin/pogo pin that once makes contact with the thin piece of metal will trigger the patting animation.
I’ll share that again here.
So, I can just recommend when you pat EMO, apply as little pressure as possible and it should work
