Gladius is the world’s first 5-thruster mini-size underwater drone with Intelligent Control algorithms .
The M2 is the world’s first professional observation underwater ROV with 8 vectored thrusters, and is designed for light-duty professional and enterprise use.
In our opinion, an 'underwater drone' is an entry level ROV (remotely operated vehicle) system that is ≤100m depth rated, out-of -the-box ready, primarily used for video and generally very low-cost (relatively speaking). Another defining aspect of an underwater drone is its inability to add auxiliary payloads like sonars, water quality probes, etc.
If you find yourself liking what you see with these underwater drones, but they fall short of your requirements for one reason or another, please take a look at the BlueROV2 by following the link below.
