    I want to do that if I push a button then the robot has a maximum velocity that is less than the maximum velocity without to push the button
    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 ?

    Do you have a mean for measuring or estimating the robot velocity?

    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.
