for some reason drivers rotate very slow and wrong direction

you can find it in the blender file
the one attached to rotator constraint on neck bones
Hi Samy! I too do not understand what you mean regarding the drivers. However, I can see that you have some parenting inconsistencies on the DEF neck bones. This might have happened because you have the numbering of the DEF neck bones swapped. Perhaps if this is corrected you might have better results.
Here is how it looks on my rig:

Hi kkadory87,
Happy 2026!
May this be the year when you actually complete the Fundamentals course first.
I did make that my Christmas wish for you, Samy. But sadly I must have been on the naughty list because Santa did not deliver :(
Not to worry, I can still make it my New Year's Resolution.......oh wait, no I can't. But I know someone who can ;)
hehe
hi wayne
thank you, your wish came true, I finished the fundamental course and currently working on my first robot rigging.
if you may find it in your kind heart to give me advice on how I built the rig after I finish it I would be very glad
p.s.
Is it possible to contact you on discord or not?
happy new year and merry Christmas to you
Yay!!!!!
Although you haven't finished all your exercises yet kkadory87
By my recollection you have the Wrangler, Stretchy Chain and the IK set-up left to complete.
I believe in you Samy - you can do it
you can do it
you can do it
(as for contacting me on Discord - I am not really active over there - here is the best place but yes you can contact me about your rigging)
