Wire in the Cable-Driven System of Surgical Robot

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
During the evolution of the surgical robot, cable plays an important role. It translates motion and force precisely from surgeon's hand to the tool's tips. In the paper, the vertical wires, the composition of cable, are mathematically modeled from a geometric point of view.

The Motion Suspension System – MSS: A Cable-Driven System for On-Ground Tests of Space Robots

open access: yes, 2023
Robotic manipulators play an important role in space exploration and pave the way for satellite lifetime extensions, orbital asset inspections, and deorbiting. However, space robots are tested in Earth’s gravity although they are designed for zero gravity. The joints are limited in the torque which might be below of what is necessary to move on ground.

Tension Characteristics of Cable-Driven System Based on ALE Formulation

open access: yesJournal of Physics: Conference Series, 2023
Abstract This paper mainly studies the tension characteristics of cables in Cable-Driven Parallel Mechanisms (CDPMs). The exact catenary model and cable model based on the Arbitrary Lagrangian Eulerian description (ALE) are used. First, the ALE cable model and the exact catenary model are used to analyze and compare the tension at each ...

On the accuracy of $N-1$ wire-driven parallel robots [PDF]

open access: yes, 2013
A $N-1$ wire-driven parallel robot is a robot for which all the $N \ge 3$ wires are connected at the same point of the platform, allowing to control the location of this point. We are interested in the positioning accuracy of such a robot.

Cable-Driven Mechanism Models for Sensitive and Actuated Minimally Invasive Robotic Instruments

open access: yesApplied Sciences
Cable-driven mechanism models are, usually, included in actuated systems; however, recently, their use for sensitive systems has been explored. In this paper, two cable-driven multi-body mechanism models are compared, underlining advantages and ...

Interpreting the effects of DNA polymerase variants at the structural level

open access: yesMolecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

The kinematics of the redundant $N-1$ wire driven parallel robot [PDF]

open access: yes, 2013
We address the kinematics of the redundant $N-1$ wire-driven parallel robot, i.e. a robot with $N > 3$ wires connected at the same point on the platform. The redundancy allows one to increase the workspace size.
