Your problem lies here:

for(int i =0; i < 10; i=+1){
    getWatchdog().feed();
    robotdrive.drive(1,0);
    Timer.delay(3);
    getWatchdog().feed();
}

You're using a timer delay in a loop. That means that everytime the loop is called (which is two, for whatever reason) you will have a 3 second delay. Plus, since you're wanting to drive for a set amount of time in autonomous, why not use the nifty Timer class?

Timer timer = new Timer(); // you should put this in your constructor.

public void autonomous() {
    while(isAutonomous()) {
        timer.start();
        while(timer.get() < 3) { // while the timer is < 3, drive forward.
            robotDrive.drive(1,0);
            timer.stop(); // stop the timer after 3 seconds
        }
        robotDrive.drive(0,0); // stop the robot from driving any further.
    }
}
