Individual Task - Infinite Loop

You are to design a new Program. Your Robot will be tested inside a 'walled structure'.

The resources below will help you. You are advised to use Loop / Repeat code.

Your Robot needs to:

1) Move Forwards in a straight line.

2) Back up and then Rotate 180 degrees just before it collides with a Wall (use Motion Sensor - your Robot shouldn't actually touch the wall.)

3) Make some type of 'noise' and then start moving forwards again.

4) STOP when something RED is held above the Colour Sensor.
