Junkai Huang

I build things that move, think, and sometimes break.

Student engineer working at the intersection of embedded systems, robotics, and embodied AI. I write firmware, train robots, and occasionally race karts.

Featured Projects

A selection of engineering and research work I'm proud of.

Competitions

RoboMaster Swerve Drive Infantry Robot

Led embedded development for a swerve-drive infantry robot — custom encoder design, gimbal stabilization, omnidirectional chassis control, and power management. Won 1st place at the Southwest Regional and 3rd nationally at RoboMaster 2025.

RoboMaster 7-DoF Arm Engineer Robot

Embedded lead for a 7-axis robotic arm engineer robot with mecanum chassis. Built the full control stack from ROS2+MoveIt2 motion planning on the host PC down to real-time joint control on STM32.

Robotics & Embodied AI

Embodied AI Housework Robot

Built a mobile manipulation system based on Diffusion Policy and VLA (π0.5) for household tasks. Deployed on a 7-DoF arm + differential drive base, with TeleOp data collection using a single smartphone.

π0 VLA Real-Robot Reproduction

Reproduced the π0 vision-language-action model on a real robot arm from scratch in 3 months — built the arm, collected data, fine-tuned, and deployed end-to-end.

Beyond Engineering

Some of the things I enjoy when I'm not writing firmware.

Karting

The closest thing to racing without a license.

Cycling

Two wheels, no motor, plenty of suffering.

Desk Setup

Where the magic happens (and the cable management never ends).
