About Me
NANDA SHAPERS Ambassador · Seeed Techsmith
I’m Muwon Lee, an independent researcher and embedded systems engineer at Chungbuk Science High School.
I study ground-effect estimation and flight dynamics, develop STM32 drone firmware, and build electronics and robotic systems. GES is my main research focus; Delibot and cbgpu are part of my team engineering work.
I also write about low-level development and authored 레지스터부터 시작하는 MCU 개발, a book on register-level MCU programming.
WHAT I DO
Flight dynamics, simulation & control
My career &
experience
Ambassador & Techsmith
NANDA SHAPERS · Seeed
NOW
Currently a NANDA SHAPERS Ambassador and a Seeed Techsmith, alongside independent research and embedded-systems development.
Independent Research
GES · Flight dynamics
GES
Researching onboard-sensor-based ground-effect estimation over irregular terrain. Published as a preprint, with separate offline prediction and closed-loop control evaluations.
Embedded Engineering
Individual projects
MCU
Developing drone firmware for extreme-environment experiments, designing a custom BEC PCB in KiCad, and exploring autonomous drone infrastructure.
Technical Author
레지스터부터 시작하는 MCU 개발
BOOK
Published a book covering register-level MCU development, from memory maps and GPIO to clocks and interrupts. Also wrote a series on STM32 LL drivers.
Team Engineering
