The code below allows the AEV to travel half of the track:
reverse(4); // Reverse all motors
motorSpeed(4,35); // Run all motors at 35% power
goToRelativePosition(-122); // The AEV will move to about 5 feet
reverse(4); // Reverse all motors
motorSpeed(4,25); // Run all motors at 25% power
goFor(2); // Run the previous command for 2 seconds
brake(4); // Brake all motors
goFor(2); // Run the previous command for 2 seconds
motorSpeed(4,22); // Run all motors at 22% power
goToRelativePosition(460); // The AEV will move about to 19 feet
reverse(4); // Reverse all motors
motorSpeed(4,23); // Run all motors at 23% power
goFor(2); // Run the previous command for 2 seconds
brake(4); // Brake all motors
goFor(2); // Run the previous command for 2 seconds
reverse(4); // Reverse all motors
motorSpeed(4,30); // Run all motors at 30% power
goToRelativePosition(183); // The AEV will move to about 7 feet
reverse(4); // Reverse all motors
motorSpeed(4,23); // Run all motors at 23% power
goFor(2); // Run the previous command for 2 seconds
brake(4); // Brake all motors
reverse(4); // Reverse all motors
