I am an undergraduate at Northwestern University, majoring in Computer Science at the McCormick School of Engineering. My research interests are embodied agents, foundation models for robotics, and human data for robotics.
Embodied Agents: Building general-purpose agentic systems that interact with the physical world, perform dexterous manipulation, and excel at long-horizon tasks.
Foundation Models for Robotics: Advancing vision-language-action models, world-action models, and tactile foundation models for general-purpose robotics.
Human Data for Robotics: Scaling robotic foundation models with egocentric video and other human-generated data.

Generative Bayesian Filtering for Manufacturing State Estimation
Lei Cao, Sihang Feng, Jixin Yan, Tao Sun, Naichen Shi
International Symposium on Flexible Automation (ISFA), 2026Under Review

Embodied Harness

Litchi AI @ Tsinghua Spatial Intelligence LabJun 2026 – Present
A two-tier embodied-agent framework in which a VLM planner orchestrates fresh-context navigation, manipulation, and verification agents across swappable simulator, policy, model, and tool backends. Verification-gated recovery and a resumable evaluation pipeline backed by 402 tests improve success over flat-policy baselines by 10% on VLN-CE navigation and 33% on BEHAVIOR-1K long-horizon mobile manipulation.
An open-source NVIDIA Isaac Lab framework for the LeRobot SO-101 arm that unifies PPO with distillation, ACT, and Diffusion Policy training. A shared joint-position action space and real-arm deployment bridge allow one checkpoint to run in simulation and on a Feetech follower without sim-to-real action conversion.
SpiderPi Hexapod Robot
Jixin Yan
Introduction to Robotics Lab, Northwestern UniversityJan 2025 – Mar 2025
A 6-DOF hexapod with tripod and wave gaits driven by inverse kinematics and IMU-based PD feedback, paired with A* planning and a subsumption-based controller for real-time obstacle avoidance. A frontier-based exploration pipeline incrementally builds the occupancy map and prioritizes frontiers by information gain for autonomous coverage.
