Hexapods are the most widely used parallel robots which provide 6 DOFs. To obtain high precision and high dynamic performance in hexapods, it is necessary to design them in such a way that low eigen frequencies are avoided (while the eigenf requencies are also functions of the complex 3D geometry of hexapods). Theoretically, maximizing the lowest eigen frequency leads to a condition where multiple eigen frequencies become equal, which is known as (complete or partial) dynamic isotropy. Thus, one may consider a dynamically isotropic hexapod as the optimal design solution, where precision and dynamic performance is a goal. In this work, we analytically address this problem and establish a practical guideline in order to design generalized hexapods with complete dynamic isotropy. The findings are based on the recently defended PhD dissertation by Behrouz Afzali-Far. PB - JACoW Publishing CP - Geneva, Switzerland ER -
