A Versatile Underactuated Robotic Hand for Cloth Manipulation

ICRA 2026poster

Traditional cloth manipulation often employs low- DOF grippers to simplify hardware. However, this approach presents significant challenges for algorithms due to the complex and dynamic behavior of fabrics. To address these limitations, we propose a novel approach based on a human-hand-like de- sign…

Cosmos-Surg-DVRK: World Foundation Model-Based Automated Online Evaluation of Surgical Robot Policy Learning

RA-L 2026

The rise of robot-assisted surgery and vision language-action models has accelerated progress in autonomous surgical policies and efficient assessment strategies. However, evaluating these policies directly on physical robotic platforms such as the da Vinci Research Kit (dVRK) remains hindered by hi

Fluoroscopy-Constrained Magnetic Robot Control Via Zernike-Based Field Modeling and Nonlinear MPC

ICRA 2026poster

Magnetic actuation enables surgical robots to navigate complex anatomical pathways while reducing tissue trauma and improving surgical precision. However, clinical deployment is limited by the challenges of controlling such systems under fluoroscopic imaging, which provides low framerate and noisy p…

SurgiPose: Estimating Surgical Tool Kinematics from Monocular Video for Surgical Robot Learning

IROS 2025

Imitation learning (IL) has shown immense promise in enabling autonomous dexterous manipulations, including in learning surgical tasks. To fully unlock the potential of IL for surgery, access to clinical datasets is needed, which unfortunately lack the kinematic data required for current IL approach

Are U a Joke Master? Pun Generation via Multi-Stage Curriculum Learning towards a Humor LLM

ACL 2024findings

Although large language models (LLMs) acquire extensive world knowledge and some reasoning abilities, their proficiency in generating humorous sentences remains a challenge. Previous research has demonstrated that the humor generation capabilities of ChatGPT are confined to producing merely 25 uniqu…

From Coarse to Fine: A Distillation Method for Fine-Grained Emotion-Causal Span Pair Extraction in Conversation

AAAI 2024technical

We study the problem of extracting emotions and the causes behind these emotions in conversations. Existing methods either tackle them separately or jointly model them at the coarse-grained level of emotions (fewer emotion categories) and causes (utterance-level causes). In this work, we aim to joi…

TOREE: Evaluating Topic Relevance of Student Essays for Chinese Primary and Middle School Education

ACL 2024findings

Topic relevance of an essay demands that the composition adheres to a clear theme and aligns well with the essay prompt requirements, a critical aspect of essay quality evaluation. However, existing research of Automatic Essay Scoring (AES) for Chinese essays has overlooked topic relevance and lacks…
