I am an undergraduate Robotics Engineering student at Beijing Institute of Technology, working at the intersection of robotics, autonomous driving, embodied AI, 3D scene representation, and AI systems engineering.
I enjoy turning research prototypes into real systems—from perception, state estimation, and navigation to inference deployment, communication architecture, testing, and fault recovery. Beyond getting a demo to run, I care about reliability, reproducibility, and graceful recovery when things go wrong.
- Currently building — 3DGS visual localization, instance navigation, and editable road-scene generation
- Exploring — ROS 2, Nav2, Habitat, VLA/VLN, world models, and AI agents
- Engineering — reliable real-robot systems, AI inference deployment, autonomous-driving infrastructure, and open-source software
- Let's talk about — embodied AI, 3D scene intelligence, robotics middleware, AI infrastructure, and research automation
- Highlights — 28 merged upstream PRs; Kaggle Bronze Medal (solo, top 9.9%)

A batch-wise extension of Point-LIO featuring within-window motion undistortion, batched EKF updates, and parallel computation for high-bandwidth LiDAR-inertial odometry.
|
A 3D annotation and AI-assisted pre-labeling platform for Formula Student Driverless point clouds, with quality gates, OpenPCDet export, and a TensorRT inference backend.

An open simulation and verification framework for reusable-launch-vehicle terminal recovery — return flight, GNC, tower and arrestor-cable catch dynamics, and a SIL → HIL → scaled-experiment path built for explainable, reproducible sim-to-real.

A three-backend (Isaac Gym / Isaac Lab / MuJoCo) reinforcement-learning classroom for robust locomotion — train a policy in one simulator, then make it prove itself under unfamiliar dynamics, sustained pushes, stairs, and a different physics engine.
