Robot only dances to songs it likes: FFT-based taste check plus BPM prediction
wavefnx · x · 2026-11-02
wavefnx explains how a music-dancing robot works: it runs an FFT internally to decide whether it likes the song—if it dislikes it, the robot won't dance at all—and then follows the rhythm via sampling and BPM prediction.
The detail shows such demos are a real-time perception-action loop with audio analysis and beat tracking, not canned motion playback.
