Design and Wrench-Feasible-Workspace Analysis for a Novel Cable-driven Parallel Robot with Movable Anchor Winches

IROS 2025

Traditional cable-driven parallel robots (T-CDPRs) typically employ multiple driving cables extending from fixed anchor points to connect with the end-effector. Once assembled, the anchor positions and the wrench feasible workspace of the CDPR are fixed and cannot be readily modified. This paper pre

Detecting Subtle Differences between Human and Model Languages Using Spectrum of Relative Likelihood

EMNLP 2024main

Human and model-generated texts can be distinguished by examining the magnitude of likelihood in language. However, it is becoming increasingly difficult as language model’s capabilities of generating human-like texts keep evolving. This study provides a new perspective by using the relative likelih…

Knowledge-enhanced Prompt Tuning for Dialogue-based Relation Extraction with Trigger and Label Semantic

COLING 2024main

Dialogue-based relation extraction (DRE) aims to determine the semantic relation of a given pair of arguments from a piece of dialogue, which has received increasing attention. Due to the low information density of dialogue text, it is difficult for the model to focus on key information. To this end…

Soul-Mix: Enhancing Multimodal Machine Translation with Manifold Mixup

ACL 2024long

Multimodal machine translation (MMT) aims to improve the performance of machine translation with the help of visual information, which has received widespread attention recently. It has been verified that visual information brings greater performance gains when the textual information is limited. Ho…

Zero-Shot Spoken Language Understanding via Large Language Models: A Preliminary Study

COLING 2024main

Zero-shot Spoken Language Understanding (SLU) aims to enable task-oriented dialogue systems to understand user needs without training data. Challenging but worthwhile, zero-shot SLU reduces the time and effort that data labeling takes. Recent advancements in large language models (LLMs), such as GPT…

An All-in-one Cable-driven Parallel Robot with Flexible Workspace and Its Auto-calibration Method

IROS 2022poster

For traditional cable-driven parallel robots (CD-PRs), changing the workspace is relatively difficult, which needs to reconfigure the anchor points and the external frame. The main reason is that the winch is separated from the moving platform, and a series of pulleys are applied to guide the drivin…
