Construction of Stewart-Gough platforms with motion curve of genus 7 (Documentation in progress)

 
 

The Macaulay2 script StewartGough.m2 and the Maple Worksheet StewartGoughGenus7.mw provide the routines for the construction of an exceptional Stewart-Gough platform with motion curve of genus 7.

Animations of such a mechanism can be found here and here.
