Industrial Physical AI Researcher

I bring Physical AI to the industrial floor — translating field constraints into embodied systems that actually run on commodity sensors and existing ROS 2 stacks.

Research focus on Industrial AMR Navigation, Low-cost Sensing, LLM/VLA-Driven Operations, and Physical AI deployment.

Industrial Physical AI (IPAI)

A research direction that brings Physical AI down to the industrial floor — across the two embodied platforms that drive modern manufacturing: the Industrial AMR that moves, and the Manipulator that acts. Both run on commodity sensors, legacy ROS 2 stacks, and the same operational metrics. My research builds the AI that ships across both.

Where I Work Today

Industrial AMR

Mobile platforms that move across the floor.

  • Costmap layers & policy-aware navigation (Time-aware, Cooperative, LLM-driven)
  • Low-cost 2D LiDAR perception & mapping (PINMAP)
  • Multi-AMR cooperation & lifelong learning
  • Operational metrics: throughput, jerk, collision risk
Where I'm Extending Next

Manipulator

Articulated arms that act on the world.

  • VLA (Vision-Language-Action) for industrial manipulation
  • Foundation models grounded in operational constraints
  • Embodied AI for repeatable, deployable tasks
  • Industrial fault diagnosis & action verification

Both platforms live on the same operational floor, and both ask the same question: can we make embodied intelligence actually deployable? Industrial Physical AI is my answer.
