After assembling and uploading the initial sketch, RAPIRO head is turning from Left to Right. For experiment i am changing the int trim[MAXSN] = { 0, // Head yaw, but still the same movement observed. Can any one help me to getting start with correct configuration?
Also, once switch on - servo motor is making some noise. Is it normal behavior ?

I have the exact same problem. I'm charging my batteries now (thought they were fully charged but maybe not). It's only moving by a couple of degrees though, maybe less than that (so it looks like he's shaking his head really fast).

Did anyone solve this?

I've narrowed this down to his right leg, removing the head and holding him while turning on shows the right leg shaking alot which means it's not correctly initialised right?

By trial and error I modified Rfoot pitch (4) and left foot pitch (2) (turns out the buzzing was coming from there too), each time turning him on while holding him in the air, then placing him and seeing if everything was quiet. He seems to be ok now!

Now to put the head back on.

Hope this helps anyone who has the same symptoms.
