| Outline of Final Research Achievements |
The goal of this research is to formulate the dynamic rolling of tensegrity robots as a system consisting of discrete contact state transitions and continuous dynamic equations. First, we derived a graph representing contact state transitions during rolling based on geometric description of tensegrity robots. Second, we derived a set of equations of dynamic rolling of tensegrity robots to simulate their rolling over the ground. Through simulation of the rolling of a six-strut tensegrity robot and a star-shaped tensegrity robot, it turned out that these tensegrity robots could perform transitions between an axial symmetric contact and a planar symmetric contact but could not transitions between neighboring planar symmetric contacts. Additionally it turned out that strut driving enables us not only transitions between an axial symmetric contact and a planar symmetric contact but also transitions between neighboring planar symmetric contacts.
