StackChan
M5Stack's StackChan is a palm-sized open-source AI desktop robot co-created with the maker community around the CoreS3 ESP32-S3 controller. Official M5Stack materials describe a ready-to-play companion and development platform with an animated face, AI voice interaction, app-based video viewing and remote avatar control, smart-home/IoT control use cases, two feedback servos for expressive pan-and-tilt motion, NFC, touch, camera, microphones, IMU, RGB LEDs, and Grove expansion. The official documentation and product page list the K151/K151-R hardware as a shippable M5Stack kit, while independent CNX Software coverage corroborates the Kickstarter launch, open-source positioning, AI voice-assistant angle, smart-home/IoT use case, and April 2026 delivery target. It is best understood as a hackable desktop companion and maker robot, not a mobile household chore robot.
