Force control of cable-driven parallel robots

, 2016
In dieser Dissertation wird eine relativ neue Klasse von Robotern untersucht, die Seile zur Kraftübertragung einsetzt. Da Seile nur Zugkräfte übertragen, stellen die sogenannten parallelen Seilroboter hohe Anforderung an ihre Regelung. Die in dieser Arbeit zu Grunde gelegten Seilroboter besitzen mehr Seile als Bewegungsfreiheitsgrade der Plattform und ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

MODELING ANALYSIS OF A SPATIAL 3T CABLE-DRIVEN PARALLEL ROBOT

Jixie qiangdu, 2015
A spatial 3T cable-driven parallel robot with four cables has been designed and manufactured. The kinematic models of the 3DOF cable-driven parallel robot have been established to discuss the deformation of cables in the large scale system.

Pose-estimation methods for underactuated cable-driven parallel robots

Mechanism and Machine Theory
Cable-Driven Parallel Robots (CDPRs) displace the end-effector (EE) by means of cables configured in a parallel fashion. When a CDPR employs fewer cables than the degrees of freedom (DoFs) of its EE, it is underactuated and underconstrained. As a result, only a limited subset of the EE DoFs can be controlled assigning specific cable lengths, and ...

Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices

Advanced Materials Technologies, EarlyView.
This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...

Concept for a large master/slave-controlled robotic hand [PDF]

A strategy is presented for the design and construction of a large master/slave-controlled, five-finger robotic hand. Each of the five fingers will possess four independent axes each driven by a brushless DC servomotor and, thus, four degrees-of-freedom.

In Situ Copper Electroplating Turns Material Extrusion 3D Printers Into Metal–Polymer Hybrid Fabricators

Advanced Materials Technologies, EarlyView.
An in situ electroplating approach for MEX 3D printing is proposed, enabling copper deposition during the fabrication of conductive polymers. The method combines a printer‐integrated plating head, ML‐based g‐code control, and stop‐and‐go printing, achieving near‐bulk copper conductivity and enabling fully embedded, assembly‐free electronic components ...
