 We wish to implement a behavior that handles a situation where the robot is close to a surface in the directions front, left and right and makes a u-turn and drives in the opposite direction. To do this we use the following code (Fig.4):
 
 ```
-// Back up and turn 180 degrees
-
 if ( leftDistance < stopThreshold && rightDistance < stopThreshold && frontDistance < stopThreshold ){
 // back up
 
-car.backward(power, power);
+                car.backward(power, power);
             	Delay.msDelay(ms);
             	 
             	// Turn 180 degrees
