The Dimensional Synthesis of Spatial Cable-Driven Parallel Mechanisms
Journal of Mechanisms and Robotics, 2013This paper presents a method for the dimensional synthesis of fully constrained spatial cable-driven parallel mechanisms (CDPMs), namely, the problem of finding a geometry whose wrench-closure workspace (WCW) contains a prescribed workspace. The proposed method is an extension to spatial CDPMs of a synthesis method previously published by the authors ...

Mechanism Design and Analysis for an Automatical Reconfiguration Cable-Driven Parallel Robot
2017 2nd International Conference on Cybernetics, Robotics and Control (CRC), 2017An automatical reconfiguration cable-driven parallel robot (ARCPR) is optimally designed on the basis of conventional cable-driven parallel robots, and it can realize the change of degrees of freedom (DOFs) from two to six. The 3D model for the ARCPR is built, and then the kinematics characteristics of the rotating guide-bar mechanism is analyzed.

Modelling of anal sphincter tone based on pneumatic and cable-driven mechanisms
2017 IEEE World Haptics Conference (WHC), 2017Motivated by the need for improving a haptics-based simulation tool for learning and training digital rectal examinations, a sphincter tone model and its actuation is conceived and developed. Two approaches are presented: one based on pneumatics actuation and the other using cable-driven mechanical actuation using servo motors.

Modelling of cable wrapping phenomenon towards improved cable-driven mechanisms
2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013Traditional parallel driven cable robots relied on the fact that the cables connecting the fixed frame and the moving platform remain straight and taut under tension during operation. Most studies implicitly or explicitly modelled the cables as straight lines.

Design and Modeling of a 2-DOF Cable-Driven Parallel Wrist Mechanism
2019 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2019This paper proposes a novel design of 2-DOF Cable- Driven Parallel Wrist Mechanism (CDPWM). This mechanism can achieve hemispherical movement in space which has a unconventional twin actuation. The configuration has a great flexibility (with no singular points within the entire motion range), and a large stiffness of 1.07 × 106 Nmm/rad.

Control of an Overactuated Cable-Driven Parallel Mechanism for a Radio Telescope Application
IEEE Transactions on Control Systems Technology, 2009The large adaptive reflector is a Canadian design concept for a new type of large-scale radio telescope. This new telescope would be composed of a reflector made of individually actuated panels and a multitethered feed platform held aloft by an aerostat. This paper focuses on the position and orientation control of the feed platform. Models of both the

Design and Analysis of a Cable-Driven Flexible Finger Based On Continuum Mechanism
2018 IEEE International Conference on Cyborg and Bionic Systems (CBS), 2018Continuum manipulators have attracted lots of interests in the past few years, due to their super flexibility and dexterity. In this paper, a cable-driven flexible finger is designed and analyzed based on continuum mechanism. Compared with traditional rigid-link fingers, the proposed flexible finger shows excellent compliance and adaptivity. Mathematic

Development of a dexterous cable driven spine mechanism for humanoid robots
2009 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2009In order to achieve more vivid human-like motion, a 3-DOF spine mechanism is developed. Two degrees of freedom (pitch and roll) are driven by three cables and the other one (yaw) is driven by gear and pulley. The mechanism is light-weighted and is capable of sustaining heavy load.

Optimal Design of a Cable-Driven Parallel Mechanism for Lunar Takeoff Simulation
2017The technology of taking off from the lunar is of great importance for the returning of spacecraft from lunar. To verify the stability of spacecraft when taking off lunar, the force state of the spacecraft needs to be simulated accurately. Traditional simulation mechanisms are unable to meet the simulation requirements of lunar takeoff.
