+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 used the following code:
+
+```
+// Back up when all three distances are less than threshold
+            // and turn 180 degrees. 
+            if(leftDistance < stopThreshold && rightDistance < stopThreshold && frontDistance < stopThreshold ){
+            	
+            	// back up
+            	car.backward(power, power);
+            	Delay.msDelay(ms);
+            	 
+            	// Turn 180 degrees
+            	car.forward(power, 0);
+            	Delay.msDelay(2000);
+            	car.backward(0, power);
+            	Delay.msDelay(2000);
