Advanced Robotics & Embodied AI

Eight years managing large-scale construction projects convinced me that the industry's labor shortages and stagnant productivity share a common cause: physical production still depends on manual experience, even as digital design and planning have advanced far ahead of physical execution. My research closes this last-mile gap by advancing embodied intelligence for construction production — enabling robots to perceive physical conditions, understand design intent, and autonomously execute assembly amid variation, uncertainty, and accumulated error, rather than requiring perfectly standardized components and environments.

Using industrialized wood-frame construction as a testbed, I have built an integrated pipeline spanning component perception, digital-model updating, robotic planning, and physical assembly, validated on ABB IRB 6620 industrial robots. My work progresses through vision-driven adaptive control, learning-based assembly-level perception, and long-horizon planning with reinforcement learning — while exploring how Vision-Language-Action (VLA) models can be integrated with deterministic closed-loop control to combine semantic generalization with industrial-grade precision and safety.

Upcoming Article

Randomized Single-Stud Grasping & Fixed-Target Placement Trials

Validation trials for a computer vision-based robotic wood-frame assembly system. In each trial a 2×4 stud is randomly placed in the camera's field of view under clutter, partial visibility, and varying illumination. The system uses RGB-D perception and geometry-consistent 6D pose estimation to identify and refine the target pose, update the digital twin, plan a collision-aware trajectory, and execute grasping, transport, and placement at a predefined target.

Research Interests

  • Embodied AI for Construction Production: Enabling robots to perceive physical conditions, understand design intent, and autonomously execute assembly amid variation, uncertainty, and error accumulation.
  • 6D Pose Estimation for Robotic Assembly: Progressing from CAD-free geometric reconstruction to learning-enhanced pose refinement — combining learned coarse initialization with geometric registration for robust, high-precision estimation under occlusion and clutter.
  • Perception Benchmarks & Assembly Metrics: Building high-resolution 6D pose-estimation datasets and assembly-oriented evaluation metrics, such as End-Vertex Distance, to quantify interface-level placement accuracy.
  • Closed-loop Visual Servoing: Adaptive control laws and real-time feedback loops for precision-critical robotic assembly and construction-scale manipulation.
  • Long-Horizon Assembly Planning: Structured assembly-graph representations with graph neural networks and reinforcement learning to sequence operations and recover from failures.
  • Digital Twins & Sim-to-Real Pipelines: High-fidelity Isaac Sim/Lab environments for training, evaluating, and safely transferring robotic policies to industrial workstations.
  • General-Purpose Manipulation & VLA Models: Evaluating vision-language-action models (e.g., π₀, ACT) to identify their potential and limitations for construction tasks and industrial manipulators.
