I am a Ph.D. student in Computer Science at the National University of Singapore, advised by Prof. David Hsu. My research primarily focuses on developing compositional reasoning algorithms and multimodal interaction systems for intelligent robots to adaptively perform assistive tasks in dynamic and open human-centered environments .
Previously, I worked as a Research Assistant with Prof. Max Q.-H. Meng. I received my B.E. in Automation from the Harbin Institute of Technology, Shenzhen in 2021. During my junior year, I was a visiting student at UC Berkeley, working with Prof. Koushil Sreenath.
I love playing basketball 🏀 and table tennis 🏓 in my free time. I am also open to collaborating with people to explore the possibilities of robotics in various fields. Read more about my research or get in touch.

We propose a novel, expandable state representation that provides continuous expansion and updating of object attributes from the Language Model's inherent capabilities for context understanding and historical action reasoning. Our proposed representation maintains a comprehensive record of an object's attributes and changes, enabling robust retrospective summary of the sequence of actions leading to the current state. We validate our model through experiments across simulated and real-world task planning scenarios, demonstrating significant improvements over baseline methods in a variety of tasks requiring long-horizon state tracking and reasoning.

We propose a hybrid physical Human-Robot Interaction model that involves leash tension to describe the dynamical relationship in the robot-guiding human system. This hybrid model is utilized in a mixed-integer programming problem to develop a reactive planner that is able to utilize slack-taut switching to guide a blind-folded person to safely travel in a confined space. The proposed leash-guided robot framework is deployed on a Mini Cheetah quadrupedal robot and validated in experiments.

We propose a novel guidance robot system with a comfort-based concept. To allow humans to be guided safely and more comfortably to the target position in complex environments, our proposed force planner can plan the forces experienced by the human with the force-based human motion model. And the proposed motion planner generate the specific motion command for robot and controllable leash to track the planned force. Our system has been deployed on Unitree Laikago quadrupedal platform and validated in real-world scenarios.

We propose a novel mobile manipulation system with applications in luggage trolley collection. The proposed system integrates a compact hardware design and a progressive perception stragy and MPC-based planning framework, enabling the system to efficiently and robustly collect trolleys in dynamic and complex environments. We demonstrate our design and framework by deploying the system on actual trolley collection tasks, and their effectiveness and robustness are experimentally validated.

This paper presents an autonomous nonholonomic multi-robot system and a hierarchical autonomy framework for collaborative luggage trolley transportation. This framework finds kinematic-feasible paths, computes online motion plans, and provides feedback that enables the multi-robot system to handle long lines of luggage trolleys and navigate obstacles and pedestrians while dealing with multiple inherently complex and coupled constraints. We demonstrate the designed collaborative trolley transportation system through practical transportation tasks in complex and dynamic environments.
