DC motors VIBRATING and not MOVING

Question

I am making a hand gesture controlled tank.I made a code to test the dc motors on Arduino UNO, but the problem is that motors are just vibrating and not moving. The code is:

#include <AFMotor.h>

AF_DCMotor motor1(1, MOTOR12_1KHZ); 
AF_DCMotor motor2(2, MOTOR12_1KHZ);
AF_DCMotor motor3(3, MOTOR34_1KHZ);
AF_DCMotor motor4(4, MOTOR34_1KHZ);

void setup() {


motor1.setSpeed(255);  
motor2.setSpeed(255);
motor3.setSpeed(255);
motor4.setSpeed(255);
}

void loop() {

// Serial.print("tien");

motor1.run(FORWARD);     
motor2.run(FORWARD);
motor3.run(FORWARD);
motor4.run(FORWARD);
delay(10);

//Serial.print("lui");

motor1.run(RELEASE);      
motor2.run(RELEASE);
motor3.run(RELEASE);
motor4.run(RELEASE);
delay(10);


motor1.run(BACKWARD);     
motor2.run(BACKWARD);
motor3.run(BACKWARD);
motor4.run(BACKWARD);
delay(10);

//Serial.print("tack");

motor1.run(RELEASE);      
motor2.run(RELEASE);
motor3.run(RELEASE);
motor4.run(RELEASE);
delay(10);
}

I don't know why it isn't moving. I checked it replacing the wires, but same is happening. I checked them individually connecting to the batteries and they are working pretty well. Please HELP!!

If you set the delay to 10 ms, this is what happens: -motor moves clockwise for 10 ms -motor stops for 10 ms -motor moves counter clockwise for 10 ms -motor stops for 10 ms -loop

And since 10ms (milliseconds) is a very small amount of time it appears that the motor is vibrating.

To make it move, increase the delay to something like 1000 ms which is 1 second.
