4-Wheel-Drive Ambulance with Lights and Siren

Two Linkbots have been set up on the virtual grid, one facing forward and one facing backward, separated by approximately 2.5 inches. The virtual setup models two connected hardware Linkbots, as shown below (with a cube connector between them). 

In this activity you are to use a non-blocking driveDistance block for the first robot and a regular driveDistance block for the second robot to get the two robots to move in tandem 36 units forward. Add blinkLEDNB and playMelodyNB commands for the first robot so that it blinks its red LED 18 times and plays a siren sound (one time through) while moving.
