How I can do this?
What kind of methods exists to control velocity?
Can I do it with gyroscope or encoder sensors ?
If the answer is yes than
1. I search after information that explain about the gyroscope sensor
2. how can i do this whit encoder sensor ?

Then use PWM to drive the motors if they are DC.
If they are stepper motors, change the step rate.
If they are AC motors, you will have to vary the frequency of the drive.
