Robot Rock
summary
Claim: multiple toy robots dance in sync to real music using only JavaScript. Implementation uses Cylon for Bluetooth discovery and UUID-based pairing, a master process that analyzes BPM and segments the track, and Node clusters to parallelize connections. Choreography is a data structure mapping beat segments to movement primitives like zips and zaps bundled as money moves. Three robots end up synchronized most of the time despite unpredictable Bluetooth latency; one unit sometimes starts late then catches up using beat-aligned cues.
