OpenROV’s Kickstarter campaign for the Trident underwater drone just blew up Kickstarter. It still has 45 days left and has already raised eight times its $50,000 goal. It’s not another quadcopter or glider, though, it’s a remote-controlled, camera-equipped underwater drone. The Trident isn’t OpenROV’s first underwater drone — in fact, the team raised funds via Kickstarter years ago for another model, as well. However, the Trident has a more hydrodynamic design, a wedge-like body that can move more efficiently and slip through narrow gaps in between rocks or other objects. Plus, it’s small enough to carry in a backpack and to fit under a plane seat when traveling.
