Recently, authors developed a general study for this kind of structure and discovered their ability of folding. In this paper, we present our recent studies on the pentagon-based tensegrity ring from a mechanical, kinematical and experimental point of view. In term of theoretical study, numerical simulations are carried out. We analyse the influence of the self–stress level and element stiffness (cables and struts) on the global system. In matter of experimentation, we present design of our first human-scaled prototype which provides a remarkable lightness. Finally, we describe the folding of this system with a comparison between experiments and numerical simulations.
