Goal

SaltyBot detects music via Jabra mic and dances in sync with the beat.

Requirements

  • ROS2 node: audio FFT + onset detection for BPM estimation
  • Beat-synchronized movements: sway left/right on beat, head bob on off-beat
  • Tempo adaptation: slow dance for ballads, energetic for fast music
  • Face display: musical note animation, happy expression
  • LED strip: color pulse on each beat
  • Duration: dance for max 60s or until music stops
  • Trigger: voice command "dance" or detect music automatically (>10s of rhythmic audio)
  • Publish /saltybot/music_state (BPM, dancing, confidence)
  • Safety: reduced movement amplitude, obstacle check between moves
