All of us in real life have a deal with some mechanisms which execute some motion. Few days ago I meet the article How to draw a straight line using Peaucellier inersor (example of this mechanism).

After all I thought that it's easy to construct any polyhedron using some mechanisms like this, but what about one mechanism (one means there is no parts , consists of other inversors).

My question is : is it possible to construct another geometry body, for example triangle.

I think the very answer is in the Roberts'curve linkage with all beams of equal size, is the answer for a triangle.

  • $\begingroup$ I mean: suppose we have $f(x,y) = 0$, which means triangle. Robert's curve build something else. $\endgroup$ – openspace Jun 24 '17 at 4:16
  • $\begingroup$ No i think with all links with the same length $l$, separated by $2l$, it draws a perfect equilateral triangle. $\endgroup$ – Brethlosze Jun 24 '17 at 4:25
