OpenROV Trident - An Underwater Drone for Everyone


by OpenROV

After four years designing and piloting underwater drones, we've taken everything we've learned and completely re-imagined what an underwater drone could be. Trident has a unique design that combines the versatility and control of an ROV (Remotely Operated Vehicle) and the efficiency of an AUV (Autonomous Underwater Vehicle). It can fly in long, straight survey lines called "transects" as well as perform delicate maneuvers in tight spaces, all while maintaining a sleek and powerful form factor.

Trident is easy to use and comes ready to go. Most importantly, it is incredibly fun to fly. (Flying really is the best term, because that's exactly what it feels like when you're piloting.)



OpenROV 2.8 vs. Trident

We've designed Trident to be ultra portable and ultra durable. The form factor is small enough to fit in a backpack or fit under an airplane seat. The side panels are overmolded with a strong, rubber coating, which gives it protection from underwater obstacles as well as rough handling when being transported.

Depth: Capable of 100m (will ship with a 25m tether - longer tethers will be sold separately)
Top Speed: 2 m/s 
Run Time: 3 hours

The data connection to Trident is a major evolution from the connection set up of the original OpenROV kit. It uses a neutrally buoyant tether to communicate to a towable buoy on the surface (radio waves don't travel well in water) and the buoy connects to the pilot using a long range WiFi signal. Using a wireless towable buoy greatly increases the practical range of the vehicle while doing transects and search patterns since a physical connection between the vehicle and the pilot doesn't need to be maintained. You can connect to the buoy and control Trident using a tablet or laptop from a boat or from the shore.

  • I wonder how this will perform in weedy lakes.

  • @Motion Man - Possibly, although in my experience sharks tend to roam murky waters where visibility is typically pretty poor.  In that sort of situation, the Trident would probably be of very limited usefulness.

  • Could these be used behind breaking waves at beaches to look for sharks ?

    The expected delivery of the first Tridents is November 2016 which is a long wait and we all know how even the most ambitious projects sometimes slip, slip, slip:-)
