Stroke-Based Variable-Damping with Force Attenuation for Capturing Large-Momentum Objects under Non-Zero Contact Velocity

ICRA 2026poster

Basketball players catch fast passes, and porters unload goods with apparent ease. These actions demonstrate how humans rely on intelligent regulation strategies to drive muscle activity. Replicating similar dynamic responses and strong impact absorption in robotics, however, remains a major challen…

A Syntactic Approach to Computing Complete and Sound Abstraction in the Situation Calculus

AAAI 2025technical

Abstraction is an important and useful concept in the field of artificial intelligence. To the best of our knowledge, there is no syntactic method to compute a sound and complete abstraction from a given low-level basic action theory and a refinement mapping. This paper aims to address this issue. T…

Steady-State Drifting Equilibrium Analysis of Single-Track Two-Wheeled Robots for Controller Design

IROS 2025

Drifting is an advanced driving technique where the wheeled robot’s tire-ground interaction breaks the common non-holonomic pure rolling constraint. This allows high-maneuverability tasks like quick cornering, and steady-state drifting control enhances motion stability under lateral slip conditions.

High Fidelity 3D Hand Shape Reconstruction via Scalable Graph Frequency Decomposition

CVPR 2023poster

Despite the impressive performance obtained by recent single-image hand modeling techniques, they lack the capability to capture sufficient details of the 3D hand mesh. This deficiency greatly limits their applications when high fidelity hand modeling is required, e.g., personalized hand modeling. T…

A Neural Rendering Framework for Free-Viewpoint Relighting

CVPR 2020poster

We present a novel Relightable Neural Renderer (RNR) for simultaneous view synthesis and relighting using multi-view image inputs. Existing neural rendering (NR) does not explicitly model the physical rendering process and hence has limited capabilities on relighting. RNR instead models image format…
