 ## Exercise 1: LEGO vehicle that exhibits a single behavior
 
-#### Task: The program AvoidFigure9_3.java implements the avoid behavior with a single ultrasonic sensor. Download the program and observe the car. Describe how the car behaves.

+#### Task 2: 
+
+Change the program so that the car drives backwards a little when all the three distances,leftDistance, frontDistance, and rightDistance are less than stopThreshold, and afterwards the car should spin around on the spot 180 degrees.

+#### Plan
 
+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.
