Cable-Driven Parallel Robots (CDPR) employ extendable cables to control the pose of an end-effector (EE). If number is smaller than degrees freedom EE, and have no special arrangement reducing EE freedoms, robot underactuated, underconstrained: as a consequence, preserves some freedoms even when all actuators are locked, which may lead undesirable free motions. This paper proposes novel methodo...

Abstract Soft robots have become important members of the robot community with many potential applications owing to their unique flexibility and security embedded at material level. An increasing number researchers are interested in designing, manufacturing, modeling, control. However, dynamic simulation soft is difficult infinite degrees freedom nonlinear characteristics that associated materi...

Experimental results indicate that time invariant linear elastic models for cable-driven parallel robots show a significant error in the force prediction during operation. This paper proposes the use of an extended model for polymer cables which allows to regard the hysteresis effects depending on the excitation amplitude, frequency, and initial tension level. The experimental design as well as...

Cable-suspended robots are structurally similar to parallel actuated robots but with the fundamental difference that cables can only pull the end-effector but not push it. From a scientific point of view, this feature makes feedback control of cable-suspended robots lot more challenging than their counterpart parallel-actuated robots. In the case with redundant cables, feedback control laws can...

Abstract Cable-driven hyper-redundant robots have been adopted in many fields for accessing harsh and confined environments that maybe inaccessible or dangerous humans. The cable actuation strategy makes the robot hardware safer increases payload reducing its weight. In this paper, a novel design of fully actuated cable-driven has proposed. This solution is pulleyless decreases mechanical compl...
