An arXiv paper describes a backpack-style device that uses gentle thrust as a physical cue to keep divers at a set distance from reefs or equipment.

A preprint posted to arXiv on 1 October by Demetrious Kutzke and Junaed Sattar describes RADMCS, a wearable robot that guides a scuba diver sideways rather than simply propelling them. The authors say it is the first device of its kind.

The robot estimates distance to nearby structures from a single camera and uses small submersible thrusters to push the diver gently, giving a felt cue to keep clear of objects such as coral reefs, drilling equipment or unexploded ordnance.

The authors report in-water studies with eight divers, in a closed-water pool and in the ocean, covering sensitivity thresholds, distance keeping and fit testing. They report that thrust at about 10% of maximum was enough to direct a diver's movement. The paper has not yet been peer reviewed.
