Automated Synthesis of Facial Mechanisms for Conversational Animatronic Robots

RSS 2026poster

Animatronic faces are a central component of socially interactive robots, enabling rich nonverbal communication through facial articulation. However, state-of-the-art animatronic faces are typically tailored systems: each new facial geometry requires extensive manual mechanical redesign, making larg…

UniUncer: Unified Dynamic–Static Uncertainty for End-To-End Driving

ICRA 2026poster

End-to-end (E2E) driving has become a cornerstone of both industry deployment and academic research, offering a single learnable pipeline that maps multi-sensor inputs to actions while avoiding hand-engineered modules. However, the reliability of such pipelines strongly depends on how well they hand…

Unified Map Prior Encoder for Mapping and Planning

ICRA 2026poster

Online mapping and end-to-end (E2E) planning in autonomous driving are still largely sensor-centric, leaving rich map priors—HD/SD vector maps, rasterized SD maps, and satellite imagery—underused due to heterogeneity, pose drift, and inconsistent availability at test time. We present emph{UMPE}, a U…

Chameleon: Fast-Slow Neuro-Symbolic Lane Topology Extraction

ICRA 2025

Lane topology extraction involves detecting lanes and traffic elements and determining their relationships, a key perception task for mapless autonomous driving. This task requires complex reasoning, such as determining whether it is possible to turn left into a specific lane. To address this challe

Delving into Mapping Uncertainty for Mapless Trajectory Prediction

IROS 2025

Recent advances in autonomous driving are moving towards mapless approaches, where High-Definition (HD) maps are generated online directly from sensor data, reducing the need for expensive labeling and maintenance. However, the reliability of these online-generated maps remains uncertain. While inco

Elucidating the Design Space of Torque-aware Vision-Language-Action Models

CoRL 2025poster

Many robotic manipulation tasks require sensing and responding to force signals such as torque to assess whether the task has been successfully completed and to enable closed-loop control. However, current Vision-Language-Action (VLA) models lack the ability to integrate such subtle physical feedbac…

Morpheus: A Neural-driven Animatronic Face with Hybrid Actuation and Diverse Emotion Control

RSS 2025poster

Previous animatronic faces struggle to effectively express emotions due to both hardware and software limitations. On the hardware side, earlier approaches either used rigid-driven mechanisms, which provide precise control but are difficult to design within constrained spaces, or tendon-driven mecha…

Reusing Attention for One-stage Lane Topology Understanding

IROS 2025

Understanding lane topology relationships accurately is critical for safe autonomous driving. However, existing two-stage methods suffer from inefficiencies due to error propagations and increased computational overheads. To address these challenges, we propose a one-stage architecture that simultan

PreAfford: Universal Affordance-Based Pre-Grasping for Diverse Objects and Environments

IROS 2024poster

Robotic manipulation with two-finger grippers is challenged by objects lacking distinct graspable features. Traditional pre-grasping methods, which typically involve repositioning objects or utilizing external aids like table edges, are limited in their adaptability across different object categorie…
