Study on multi-section continuum robot wire-tension feedback control and load manipulability Ind. Rob. (IF 1.123) Pub Date : 2020-05-08 Azamat Nurlanovich Yeshmukhametov; Koichi Koganezawa; Zholdas Buribayev; Yedilkhan Amirgaliyev; Yoshio Yamamoto
Purpose The purpose of this paper is to present a novel hybrid pre-tension mechanism for continuum manipulators to prevent wire slack and improve continuum robot payload capacity, as well as to present a new method to control continuum manipulators’ shape. Design/methodology/approach This research explains the hardware design of a hybrid pre-tension mechanism device and proposes a mathematic formulation
