Autocalibration Subsystem for Cable-Driven Parallel Robots

CoRR, 2019
For Cable-Driven Parallel Robots, the cable length is the only element we control. Better knowledge of this parameter will improve robot performances. We propose a new cable length autocalibration subsystem. It consists of an instrumented cable, inductive sensors and a controller for digital data processing.

An Origami‐Inspired Cable‐Driven Continuum Robot

Advanced Intelligent Systems
Existing continuum robots with nonstretchable skeletons are monofunctional, providing only bending degrees of freedom (DOF). Additionally, their nonembedded solid structures limit application potential. In this study, inspired by origami structures, a cable‐driven continuum robot featuring dual bending‐contraction DOF is developed.
