Trident is a multipurpose open source submarine drone. It’s ideal for:

  • Boating and fishing –  Deploy in seconds to see what’s underwater; inspect props, rudders, hulls, and anchors; find fish better than a fish finder
  • Diving  – Scout and find dive sites; explore up to 100m and more technical locations using Trident; stream live video to friends who can follow along on your dive from the boat; dive masters can keep an eye on everyone from the boat
  • Explore – Easy, fast, and fun; capture beautiful video using Trident’s underwater-optimized HD camera; share video with friends; join a community of explorers who share the same curiosity for the underwater world
  • Marine Science – Upgradeable and expandable to meet the needs of your projects; Trident has a mounting standard for new instrumentation, modules, or payloads; Trident communicates with peripherals through a standard wireless protocol; open-source license allows developers to extend the software

Everything you need to pilot your drone is just a web browser and a laptop, tablet, or smart phone.

Trident is designed to be able to add new sensors, instruments, and payloads. The software that powers Trident is a live open-source project. Thanks to the ocean-loving community, you can find all the software and hardware files online as well as a vibrant and enthusiastic community to share adventures, ask questions, and meet other people with passion for exploration.

The Openrov 2.8 starter kit is already available: Beaglebone Black and Arduino MEGA microprocessors provide a flexible and powerful developer platform with dozens of input/output channels and plenty of computing power for user-designed features and experiments
