What is the basic psuedocode for the mechanical arm? I know it has $3$ iterations and a right side resting point. But i think im lost on the measurements of the swing. Assume you have created a mechanical arm that can hold a pen and a piece of paper. The arm can perform the following tasks:

Lower the pen to the piece of paper. The first time the pen is lowered, it faces right and is ready to move to the right.

Raise the pen from the paper

Move the pen $1$ inch along a straight line, drawn in the direction the pen is facing. $($If the pen is lowered, this action draws a $1-$inch line; if the pen is raised, this action repositions the pen $1$ inch.$)$

Turn $90$ degrees to the right.

Draw a circle that is $1$ inch in diameter. The circle is drawn clockwise from the starting point.

Additionally, assume the arm knows the answer to questions such as$,$Is the pen facing right?$$
