The M5Stack StackChan - Kawaii Co-Created Open-Source AI Desktop Robot is a compact, customisable desktop robot designed for interactive AI and maker projects. Co-created by M5Stack and its user community, StackChan is built around the CoreS3 platform with an ESP32-S3 processor, offering Wi-Fi and Bluetooth connectivity along with 16MB Flash and 8MB PSRAM for running applications and AI features. It features a 2.0" touchscreen used as an animated face, along with a camera, microphones, speaker, and sensors to enable voice interaction, visual input, and expressive behaviour. Two servo motors provide pan and tilt movement, giving the robot a range of lifelike motions and personality. Designed as an open-source platform, StackChan can be programmed using tools such as Arduino, UiFlow2, or other supported environments, making it suitable for experimenting with AI assistants, smart home control, and interactive robotics. Its open design and active community allow users to customise both hardware and software, extending functionality and creating unique behaviours. Suitable for a wide range of projects and applications! * Your lively desk companion: StackChan comes alive on your desk! It listens when you talk, responds to your touch, and even watches you when needed. Watch it chat, make playful expressions, and even dance for fun. Every moment with StackChan is full of surprises and entertainment. * AI agent for daily life: StackChan can also be your daily assistant. Chat with it to get answers to everyday questions, set reminders, or control your smart-home devices and phone with simple voice commands. * A cute monitor: StackChan can be your little home guardian. Whether it’s keeping an eye on kids, checking on elders, or noticing unexpected visitors, you can stay in the loop right from your desk or through the app. * Get more fun with your phone: StackChan becomes even more playful, expressive, and connected when paired with the app. * Full control at your fingertips: Use the app to remotely control all of StackChan’s functions, such as expressions, movements, and smart-home, anytime and anywhere. * Copy your mood: Learning your expressions and repeating what you say, StackChan lets you communicate in a playful way. You can even use it remotely to interact with family, friends, or coworkers, especially on days when you’d rather not be on camera yourself. * Make it yours: Change how StackChan looks and behaves. Dress it up with outfits and stickers, tweak its reactions, or download creations shared by the community. Every StackChan can look and act a little differently, just like its owner. * Build it deeper: StackChan is fully open-source, inside and out. From software and firmware to hardware design, everything is open to exploration. Build new functions, connect modules, and create your own ideas with MicroPython, Arduino, and open I/O.
