Plot the circle.

Now use line() to draw the armature, using a higher LineWidth and a Marker of 's' (square) and a MarkerFaceColor of 'r' (red), possibly using a MarkerEdgeColor of 'k' (black). Store the handle of this line().

See http://www.mathworks.com/help/matlab/ref/line_props.html .

Then, at each step of the animation, set() the line XData and YData properties to reflect the new line position. Then call drawnow() to make the updated line show up.
