OpenROV v2.7 Kit (Discontinued)

See our newest ROV v2.8 Kit!

Gain access to an uncharted under-sea world and the amazing, supportive community of people who are curious about it! The OpenROV DIY kit provides you with your own underwater ROV, capable of diving to 75m. The kit is fun to build and you don't need to be an expert, but you will need to solder, glue, and use basic hand tools. It's a great project to learn how to hack off-the-shelf electronics, solder wired components, and build things for a marine environment. You're also not alone! You can get help from the community, give and receive feedback on the instructions, and you are backed up by our wonderful technical support team. You'll come away with some new skills and the ability to explore the world around you from a whole new perspective!

The OpenROV v2.7 is the best ROV we've ever built. It streams HD video back to a laptop over an ultra-thin two-wire tether. It maneuvers using the same thruster configuration as previous models, however new hydrodynamic adjustments, new motors, and new motor speed controllers have resulted in greatly improved handling and control. A new LED board provides even more illumination in the depths, and the lasers provide both scaling and distance measurement capability.
