  • Learning Agile Intruder Interception trains an interceptor quadrotor policy using only the 3D direction unit vector to the target and differentiable quadrotor dynamics, without requiring relative position or distance signals.

MARINE AND SURFACE VEHICLES

  • Cross-Platform Control for Autonomous Surface Vehicles uses adaptive RL to achieve zero-shot cross-platform trajectory tracking from a single trained policy, covering widely varying hull and actuation characteristics.
  • Path planning for unmanned naval surface vehicles offers new approaches to real-time avoidance of both fixed and moving obstacles including boats, swimmers, and other USVs.
  • An underwater robot image-processing framework for construction site monitoring addresses real marine degradations beyond standard absorption and backscattering models.

CROWD AND SOCIAL NAVIGATION

  • SPLC (Social Preference Learning for Crowd Robot Navigation) applies offline RL with learned social preference rewards to produce pedestrian-compliant robot behavior without manual reward engineering.

SPACE AND SPACECRAFT

  • GAP-GDRNet tackles monocular relative pose estimation for non-cooperative spacecraft rendezvous, addressing weak texture, thin appendages, and partial occlusion with geometry-aware feature design.

📄 RESEARCH

PAPER 1: ONE DEMONSTRATION IS ENOUGH FOR REAL-WORLD ROBOTIC RL

The standard assumption has been that bootstrapping reinforcement learning on physical robots requires many demonstrations. This paper shows that a single real-world demo is sufficient to seed effective RL, dramatically lowering the data cost of on-hardware robot learning and opening the door to faster deployment cycles.

PAPER 2: ACTUATOR REALITY SHAPING FOR ZERO-SHOT SIM-TO-REAL [9]

Sim-to-real failure often comes down to motors behaving differently in the real world than in simulation. Instead of rebuilding the whole simulator, this method reshapes only the actuator output distribution to match real hardware, achieving zero-shot transfer without expensive simulator overhauls.

PAPER 3: OVERTHINK-TRIGGERED SLOWDOWN ATTACKS ON LVLM-BASED ROBOTIC SYSTEMS

A new class of adversarial attack exploits the tendency of large vision-language models to over-reason, forcing them to generate extremely long inference chains. In real-time robotic control, this latency injection can be safety-critical, and the paper demonstrates the attack is practically achievable.

PAPER 4: VT-WAM - VISUAL-TACTILE WORLD ACTION MODEL [6]

Most tactile-aware robot policies feed sensor readings directly to an action head. VT-WAM instead builds a world model that predicts how contact forces, slip, and deformation will evolve, then plans actions against that model. The result is richer use of sparse tactile signals in contact-heavy tasks.

PAPER 5: SE(2) NAVIGATION MESH FOR GROUND ROBOTS

Global navigation across multi-level environments is poorly served by existing maps. This paper proposes a navigation mesh structured around SE(2) (position plus heading) that explicitly encodes traversable surfaces and ramp connectivity, enabling more reliable path planning in complex real-world buildings and terrains.
