This is the M5StackChan: an ESP32-S3 powered desktop robot with WiFi and Bluetooth that is ready for all kinds of coding projects. It has a 9-axis IMU, 0.3MPH camera, and a proximity and ambient light sensor. This video shows how someone programmed this robot to track users as they type on their keyboard.
Made a Stackchan prototype that follows your typing. Spell checkers are nice, but when your robo buddy raises their eyebrows when you forget the “u” in “color”, it hits different.
Flow: A keyboard sends signals to a MacBook, which tells the robot where to look via Bluetooth. https://t.co/1Jg55hXNRB
