  Front-following is more technically difficult to implement than the other two
human following technologies, but front-following technology is more practical
and can be applied in more areas to solve more practical problems. In this
paper, we will analyze the detailed design of LRF groups, the structure and
combination design of coordinate system of Robot Detection System. We use
enough beautiful figures to display our novel design idea. Our research result
is open source in 2018, and this paper is just to expand the research result
propagation granularity. Abundant magic design idea are included in this paper,
more idea and analyzing can sear and see other paper naming with a start of
Robot Design System with Jinwei Lin, the only author of this series papers.
