Project description

Thumbnail image: AI-generated image 6DOF Rotary Stewart Motion Simulator: A Motion Rig Controller with WIZnet W5500 UDP Ethernet (ESP32-S3 + Desktop App) Introduction This project is a full-stack motion-simulator platform: an ESP32-S3 controller firmware designed for high-rate, hardware-timed motor pulse generation, plus a native desktop application that visualizes and tunes motion cues in real time. The author highlights a clear safety warning up front—this is heavy rotating machinery and requires proper emergency-stop hardware before any powered operation. (GitHub) Quick background: what…
