Arduino Robot Servo Controll

Hei everyone.

I am trying to control some servo motors placed on top of an Arduino Robot.
I connect the servos to de digital pins 0 and 2 in the control board, and use servo.attach( n );

I have tried to use servo motors in non PWM pins in an Arduino UNO and they move right.
But nothing happened in the robot.

Any suggestion?
Thanks.

You shouldn't use pin 0 because that is Rx for the USB.
