Applying Zephyr RTOS in Spacecraft Development
Talkat Open Source Summit Japan + AI_dev: Open Source GenAI & ML Summit + Automotive Linux Summit 2025 · 2025-12-08..12-10·
summary
A space‑robot prototype — a 220 mm spherical drone with four vectored fans and six optical distance sensors plus IMU — runs Zephyr RTOS on an STM32G431KB for propulsion and a Raspberry Pi for audio/video gateway; UART/I2C/SPI connect subsystems and the control loop executes a 10 ms main thread with five segments (preprocess, state eval, communication, idle, feedback). Development uses Windows 11 WSL2, OpenOCD debugging, remote firmware update via Pi, and a unit already launched last month under JAXA/NASA coordination.
