Hello and first of all, scuse me for my bad english.
I am trying to use servos for the movement of my robot, but i see a bad thing. When servos goes in position i set, they have a vibration..........
For example, i set a servo in 60% position. It goes to the position and it start "buzzing".......
Do you have same problem? I am thinking using motors and not servos, but it's a difficult way. If i have many servos, i will have many "buzzing", so, my robot will be very bad..........
Can someone suggest me a solution? Thank you very much and scuse me for my bad english.

My bet is your putting them to the stops farthest to the left and right. If not, it's because the item your turning or lifting is too heavy. Do calculations and see if the item is over the torque rating.
Servo amps roughly compare a generated pulse width to a "required pulse width. Differance causes the servo to move in the direction that will cause these signals to ballance. This is all ancient history, but is still true whether we are talking about analog or digital servos. If, as we will stipulate, the servo is not mechanically constrained, and if electronics were perfect, the servo would find the one position that exactly ballances the two signals, and wait quietly for the next stick jog. Of course, electronics are not perfect, and comparators have some jitter due to heat, cold, phase of the moon, or whatever, and if the jitter is read by the amp as significant enough, it will try to move a small amount. This causes the servo to buzz,whine, cough, or perform other tricks that are not expected.
