Overview

A compact inspection robot for flooded confined spaces such as ballast tanks, penstocks and water tanks, introduced in 2019 as 'the first-ever tether-less underwater drone' for these jobs. Today it runs as a tethered ROV with an optional wireless 'flyout' that uses Hydromea's LUMA optical modems. Class-certified for visual and NDT data collection and sold into hydropower, naval and offshore markets.
