AI can turn a cloud of scuba bubbles into an early warning for divers
University of Minnesota researchers have developed an AI system that can estimate a diver’s breathing rate by analyzing the bubbles released with each exhalation using ordinary camera footage. The method is contactless and eliminates the need for additional sensors on a diver’s equipment. The findings were published in The International Journal of Robotics Research.
- ▪The AI underwater robot observes bubble patterns to infer a diver’s breathing rate.
- ▪The system operates with standard video cameras, requiring no extra hardware.
- ▪It provides a lightweight solution that reduces the equipment load for divers.
- ▪The research was peer‑reviewed and appears in a robotics journal.

Opening excerpt (first ~120 words) tap to expand
University of Minnesota researchers have taught an AI underwater robot to estimate a diver’s breathing rate by watching the bubbles released with each exhalation. The contactless system, detailed in a peer-reviewed study published in The International Journal of Robotics Research, works with ordinary camera footage. Divers don’t need to squeeze another sensor into an equipment loadout that is hardly lacking for accessories.
