Vacuum cleaner
Trace a path across a room.
Robot vacuum cleaners move across a room automatically collecting dust and small debris. At a very basic level their navigation traces a straight line path, turning when they detect the end of the room.
Make
Write a program to trace across a virtual room on the turtle canvas. First by moving out of a docking station by 20 pixels, turning right and moving 4 meters (100 pixels). Once the end of the room is reached the robot moves up 20 pixels before turning left and moving across the room 4 meters. It needs to do this 5 times to cover the whole room. It does not need to return to the docking station (although this is a nice extension).
Use this boilerplate code as a starting point:
Success Criteria
Remember to add a comment before a subprogram to explain its purpose.
Complete the subprogram called `vacuum` that:
- Draws the path of the vacuum cleaner shown below.
Typical inputs and outputs from the program would be:

Evaluate
Check that your program outputs the expected result and has met the success criteria.
Check that you have:
- Used comments within the code to describe the purpose of subprograms and iterations.
