- Points C and D are the two fixed robots.
- Sides BE and BF are constructed by extending the edges of the
polygonal object in contact with the robots; side EF is
constructed by extending some other edge of the polygon.
- Point G is a vertex of the polygon on line EF; G is at a fixed
distance from E.
- As the polygon turns while remaining in contact with C and D, the
locus of B is a circular arc centered at A; the
locus of G is a Limaçon of Pascal.
