Dynamics of undeactuated cable-driven parallel robots [PDF]

, 2021
This thesis focuses on the dynamics of underactuated cable-driven parallel robots (UACDPRs), including various aspects of robotic theory and practice, such as workspace computation, parameter identification, and trajectory planning. After a brief introduction to CDPRs, UACDPR kinematic and dynamic models are analyzed, under the relevant assumption of ...

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Determination of the Cable Span and Cable Deflection of Cable-Driven Parallel Robots

, 2017
S.106-116In this paper, a method is proposed to compute the so-called cable span, i.e. the space occupied by the cables when the robot is moving within its workspace. As the cables are attached to a mostly fixed point on the robot frame, the shape of the

Kinematics Control of 3-DOF Under-constrained Parallel Robot with Variable Cable Mast Angles

Jixie chuandong, 2022
The cable-driven parallel robot is a special type of parallel robots whose end-effector is driven by cables instead of rigid rods. A three-degree-of-freedom (3-DOF) under-constrained parallel robot with variable cable mast angle is studied.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

A Practical Approach for the Hybrid Joint-Space Control of Overconstrained Cable-Driven Parallel Robots

, 2023
Hybrid joint-space control of overconstrained cable-driven parallel robots requires regulating the length of as many cables as the degrees of freedom of the end-effector, and controlling the tension of the remaining ones.
