Autonomous underwater vehicle for survey & inspection

Hydrus AUV

Miniature autonomous underwater vehicle with 4K video capabilities

Hydrus is a revolution in underwater AI robotics, developed to open exciting frontiers in ocean exploration. The fully autonomous submersible drone will transform undersea research and inspection by making data capture simple and accessible. The design of Hydrus synthesises numerous cutting edge navigational, propulsion and data capture technologies with highly developed and sophisticated artificial neural network intelligence.

As an all-in-one autonomous solution, 3D missions can be planned in minutes, without specific knowledge or training. The acoustic communication capabilities allow users to monitor and adjust missions on the fly.

Small enough to be launched and retrieved by a single person. No special watercraft is required. Upon mission completion, data can be wirelessly retrieved using a computer.

A 4K 60 FPS camera coupled with powerful lighting ensures the highest quality video and photography. An AI image processing system dynamically balances camera settings and lighting, and compensates for turbidity, even in the most challenging conditions.

Hydrus is the drone revolution, underwater.

Subsea acoustic navigation & positioning systems

Subsonus

Miniature underwater acoustic positioning system for AUVs and ROVs

Subsonus is an advanced USBL (ultra-short baseline) underwater acoustic positioning system that combines a sophisticated eight-channel hydrophone array with an integrated and tightly-coupled INS. It fuses acoustic position and Doppler velocity with inertial outputs and depth sensor data, providing highly accurate position, velocity and heading.

The miniature USBL can operate at depths of down to 1000 metres, and is ideal for marine platform stabilization and station-keeping, and underwater survey AUVs and ROVs.
