Iterative Learning Control for Deformable Open-Frame Cable-Driven Parallel Robots

ICRA 2024poster

This paper proposed an iterative learning control (ILC) scheme for deformable open-frame cable-driven parallel robots (D-CDPRs). In contrast to the straightforward inverse kinematics of the rigid frame cable-driven parallel robots (CDPRs), accurate modeling of the deformable frame poses challenges d…

Picking by Tilting: In-Hand Manipulation for Object Picking using Effector with Curved Form

ICRA 2023poster

This paper presents a robotic in-hand manipulation technique that can be applied to pick an object too large to grasp in a prehensile manner, by taking advantage of its contact interactions with a curved, passive end-effector, and two flat support surfaces. First, the object is tilted up while being…

Why-So-Deep: Towards Boosting Previously Trained Models for Visual Place Recognition

RA-L 2022

Deep learning-based image retrieval techniques for the loop closure detection demonstrate satisfactory performance. However, it is still challenging to achieve high-level performance based on previously trained models in different geographical regions. This letter addresses the problem of their depl

Efficient Wrench-Closure and Interference-Free Conditions Verification for Cable-Driven Parallel Robot Trajectories Using a Ray-Based Method

RA-L 2020

This letter introduces a novel approach to verify the feasibility of curved trajectories under both the interference-free (IFC) and wrench-closure (WCC) conditions for spatial cable-driven parallel robots (CDPRs). Existing ray-based methods can only be used either for translation or single degree-of

CASPR: A comprehensive cable-robot analysis and simulation platform for the research of cable-driven parallel robots

IROS 2016poster

The study of cable-driven parallel robots (CDPRs) has attracted much attention in recent years. However, to the best of the authors' knowledge, no single software platform exists for researchers to perform different types of analyses for CDPRs of arbitrary structure. In this paper, the Cable-robot A…
