Robotics 🤖

A full-stack robotics software engineer. From real robot, simulation, system design to cloud app.

Robotics Middleware Framework

I’m one of the core contributor of the Open RMF project. RMF is a distributed framework that manages hetogenous robot fleets and infrastructure (e.g. task allocation, scheduling and path conflict resolution).

  • Multi Robot fleet management project: site
    • Demonstration of RMF in simulation: repo
    • RMF core libraries, with C++ and Python APIs: repo
