StackChan AI Desktop Robot

M5Stack StackChan AI Desktop Robot is an interactive desktop companion that uses the CoreS3 IoT development kit as its main controller. This robot combines expressive character behavior with voice interaction, motion, sensing, wireless connectivity, and programmable control. The integrated main unit includes a capacitive touch display, camera, proximity sensor, 9-axis IMU, microSD expansion, speaker, dual microphones, and user buttons for compact AI and IoT experimentation. StackChan adds a robot body with USB-C power and data, battery operation, feedback servos, RGB LEDs, infrared communication, a three-zone touch panel, and NFC. Factory firmware supports facial expressions, motion behaviors, the XiaoZhi AI agent, iOS app video calls, remote avatars, and nearby StackChan discovery. The StackChan robot also supports development through Arduino, UiFlow2, PlatformIO, and ESP-IDF for custom functions and application prototyping. M5Stack StackChan AI Desktop Robot targets desktop companion, AI agent, voice-based question-and-answer, and smart home IoT control applications.
