hi
I use 3 servos in my robot that are HS-422 standard and HS-81 Micro Servo type.
I try to move the servo with low speed Like s 200 but i have so many vibration in my robot. I want to know that dose the vibration come from the servos or come from my robot shap(design).
if the vibration come from the servo . is there any better servo that i can buy it to avoid from this problem.
thank in advance
Without any information from you about the shape / design of your robot and how the servos are positioned and loaded I’m not sure how anybody can give useful information beyond extreme guess work. 
Just a guess… but sometimes if the servo lacks sufficiant current it can cause this chatter. I had this issue using a weak wall adaptor before. This has been a guess… only a guess.
Thank u guys i find the problem
its come from the design beacuse the servo was not so fited with the body of robot.
any way
thanks for your responce
