Summary

Physical output: LED mood indicators via ESP32-C3 and motor-based attention (turn toward speaker).

Requirements

  • LED mood display: ESP32-C3 NeoPixel ring or strip, mood-to-color mapping (happy=green, curious=blue, annoyed=red, playful=rainbow)
  • ESP32-C3 protocol: Serial or BLE from Orin, simple JSON command {mood: happy, intensity: 0.8}
  • Motor attention: cmd_vel commands to rotate robot toward active speaker
  • Speaker direction: Use mic array DOA (direction of arrival) or face detection angle
  • ROS2: Subscribe /social/persons (attention target), publish /cmd_vel for rotation
  • Smooth tracking: Proportional turn rate, dead zone to avoid jitter
  • Idle animation: Gentle LED breathing or scanning when no interaction
