Create a function that will cause the simulated robot to drive forwards over the background until one of the light sensors detects a change in the colour of the background. Provide a simple test program that demonstrates your function behaves as expected.

Create a second function that will accept two parameters and will cause the simulated robot to turn by a specified amount in a specified direction.

Using your two functions, or otherwise, create a program that will cause the simulated robot to drive over the Grey$\_$bands background and demonstrate a change in direction each time a change is detected in the colour of the background. When the robot detects the black line, it should draw a circle and the program should end. Use the following block magic when running your program.

$\%\%$sim$\_$magic$\_$preloaded $-$Cp $-$b Grey$\_$bands $-$x $100-$y $350-$a $0$

Include in your TMA document a screenshot of your code and the simulator output after running the program; also include of copy of your code as text.
