Controlling a Floor Turtle

A floor turtle is a small robot. You can enter commands into a floor turtle to make it move around on the floor on its own:
Drawing Lines and Shapes
You can put a pen inside the floor turtle: If the pen is lowered then the turtle will draw a trail on a piece of paper as it moves. If the pen is lifted up then the turtle will not draw as it moves.
