+/* Robot Rescue
+
+ In this example, the robot enters the line following mode and
+ plays some music until it reaches its target. Once it finds the 
+ target, it pushes it out of the track. It then returns to the 
+ track and looks for a second target.
+
+ You can make the robot push as many objects as you want to, just
+ add more to calls to the rescue function or even move that code
+ into the loop.
+
+ Circuit:
+ * Arduino Robot
+ * some objects for the robot to push
+ * a line-following circuit
