Assume that you have created a mechanical arm that can hold a pen. The arm can perform the following tasks: Lower the pen to a piece of paper. Raise the pen from the paper. Move the pen 1 inch along a straight line. (If the pen is lowered, this action draws a 1-inch line from left to right; if the pen is raised, this action just repositions the pen 1 inch to the right.) Turn 90 degrees to the right. Draw a circle that is 1 inch in diameter. Draw a structured flowchart or write structured pseudocode describing the logic that would cause the arm to draw or write the following. Have a fellow student act as the mechanical arm and carry out your instructions. Don't reveal the desired outcome to your partner until the exercise is complete.
