The Otter-S captures detailed cross-sectional sonar images to detect erosion, scouring, debris accumulation, or channel deformations. It supports preventive maintenance and environmental studies by providing accurate underwater profiles without disturbing natural sedimentation, making it valuable for hydrological and ecological management teams.
Its autonomous power and twin-propeller propulsion ensure stable movement through confined water environments with high pressure or current. The Otter-S accurately maps internal structures and defects via sonar, while dual cameras assist operators in verifying conditions visually—making it indispensable for critical infrastructure maintenance.
The Otter-S operates efficiently in DN500–6000 pipelines, providing real-time sonar imaging even in turbid or fully submerged conditions. Its precise defect recognition enables maintenance teams to detect blockages, sediment buildup, or deformation early, reducing the risk of overflow, collapse, or costly emergency repairs in urban networks.

It’s the first self-powered underwater sonar robot designed for drainage networks, combining dual-propeller propulsion, dual cameras, and circular sonar to perform full-pipe imaging without pre-cleaning.
It supports DN500–6000 pipelines, and with a buoyancy block installed, it can operate effectively in DN300 pipelines.
It uses a dual-helix propulsion system that resists entanglement from debris and provides smooth movement at up to 0.3 m/s in still water.
Yes. The sonar system provides clear imaging even in opaque or muddy conditions where cameras cannot capture visuals.
Deposits, deformation, cracks, foreign objects, and structural damage—all visualized through sonar mapping and camera support.
Captured sonar data is analyzed using compatible processing software to automatically generate detailed reports and defect maps.
Absolutely. Its IP68 protection and robust design make it ideal for industrial and municipal applications under harsh conditions.
Routine cleaning of the sonar and camera lenses, checking propulsion for debris, and ensuring battery integrity are sufficient for optimal performance.
