---++Component 6
Combine previous labs and add following a line.  Your robot is to follow a line (down the center of the robot), following my robot that is also following the line (staying within 2.5-3.5 robot lengths of me).  If it runs over a stop sign (i.e. red), it should stop.  If someone runs into it form behind, it should sound the alarm, spin around (180 degrees) and stop.
---+++Details
   * The "leader" follow the same black line and vary its speed slightly
---+++Parts
   * You will need an ultrasonic sensor on the front
   * You will need a color sensor in the "middle" of your robot pointing down.
   * You will need a touch sensor on the back of your robot facing out.
   * Use a block to follow the line
   * Use a block to adjust the speed (and a variable)
   * Use a block to react to the touch sensor being pressed
   * Use parallel programming to deal with the color sensor to stop the robot.
---+++Challenges
   * Have the display constantly update the min. and max. distance encountered between you and the leading robot.
