WU Robotics

Swarm Team | Software Lead

January - Present


Spring Semester: Robot Control and Plan Execution

  • Architected modular control system for interlocking self-assembling swarm robots using ROS 2 and C++, enabling coordinated docking and undocking behavior.
  • Created a custom PID action server in ROS 2 and C++ to enable smooth and accurate low-level control of robot actuators for precise movement.
  • Implemented path execution logic to unfold and dispatch high-level paths into low-level motion commands using a control algorithm layered over the PID server.
  • Developed testing action clients in Python to simulate and validate behavior across control and planning layers, enabling full-system debugging and reliability.
  • Led a cross-functional robotics team, coordinating simulation, perception, and control efforts while managing sprint planning and system integration.

Palantir Launch

March

Selected as a Palantir Launcher to visit their DC office and learn more about the company

Some stuff i did:

  • Created a Fullstack using Palantir's Foundry, React, and TypeScript to convert conversations with client into a Client Landscape
  • The Client landscape would allow users to see who reports to who, their roles, contact, and iterates off previous states, meaning its use scales exponentially.
  • Devloped using Palantir's Ontology, and no convos are stored, given increased privacy.

Learning to Code and Build

2019 - Present


My journey in coding started during the year the covid-19 pandemic put the world into lockdown. Instead of just playing video games all day, I decided why not try and create my own. I then installed the game engine Unity, followed a couple of tutorials, and from there I followed a couple of tutorials and fell in love with coding. I began following online lectures, building side projects, and more. It was fascinating figuring out and learning new coding tools from Networking, Web Development, Training AI models, and more!


Learning new exciting tools and focusing on growing as a person has became, and still is, a fundemental core of my character, and my mindset to this day.
