M5Stack StackChan AI Desktop Robots
M5Stack StackChan AI Desktop Robots are interactive desktop companions that use the CoreS3 IoT development kit as the main controller. These robots combine 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, nine-axis IMU, microSD expansion, speaker, dual microphones, and user buttons for compact AI and IoT experimentation. StackChan adds a robot body with USB Type-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 robots also support development through Arduino, UiFlow2, PlatformIO, and ESP-IDF for custom functions and application prototyping.
