Hi nate thanks for answer
The shaking occur only when i move the camera and whole robot shake!
I think motion camera cause shaking to my robot and not viceversa.  is it possible ?  
I'm trouble also for that warning message that appear repeatedly when i move camera:
 " warning : Unhandled message for driver device=16777343:7000:8:0 type=2  subtype=1 len=20"  because i think this message slow my simulation

Hello,

Does the shaking occur only when you move the camera? And does the
whole robot shake, or is it just the camera?
