Flashduck

Flashduck is an open-source ESP32-S3 desktop robot duck that walks, looks around, and interacts using voice or an agent.

Flashduck is an open-source ESP32-S3 desktop robot duck driven by six servos that control its neck, mouth, and legs. It runs two selectable interaction systems: a voice assistant version supporting wake words and web gait tuning, and DuckClaw, an on-device agent that handles text messages and direct servo control. Users assemble the robot using a DIY kit and 3D printed parts without soldering. The device features an optional camera, a 1.54-inch ST7789 display for single-eye expressions, an I2S microphone and speaker, and a rechargeable battery. It supports secondary development through open-source skills and MCP tools.
