Just curious if anyone here is doing autonomous drones or drones that are controlled via acoustic modems. Just wondering what is going on in the untethered underwater drone area right now. Cheers, -Matt

I’m working on an autonomous drone when capacity allows (which in practice means on and off at irregular times). I have purchased six Nanomodem V3 (NM3) acoustic modems that can be used both for communication (1-to-1 and swarm) and positioning (needs 3 modems with known position). These modems are…

Cool project. I’m wondering if you have considered any kind of emergency surfacing solution in the event that power is lost to critical navigation components, or water intrusion is detected, or other disasters.

What happens if whatever is supposed to run those failsafes is unable to do so?

Depends on the vehicle. As mentioned, a positively buoyant vehicle that loses power will float to the surface. Conversely, a negatively buoyant vehicle would sink. Leak sensors are generally expected/designed to detect a leak before it starts impacting major systems. As an example, if water starts …

Thanks, Eliot. Lots of good points to think about.

We are using multiple sensors and using sensor fusion to create a multispectra representation of the system’s surroundings. We have the good fortune to be operating in very clear water where lights can provide significant viewable area. The project is moving slowly in part due to me but we have the …

@Robi_Sen Thanks for the information regarding your project. I would love to hear more about it. This is maybe something you are able to share openly here in the forum (so that more can learn/be inspired from your project activities)? We haven’t had much time the last months to work on our project…

Just curious about your streaming video quality. What resolution and FPS are you able to transmit underwater?

Are you developing untethered underwater drones?
