@ben.gulmon Yes, I’m using a standard Trident with the 100 meter tether. I also use the JXD controller along with a video headset for my copilot. Since I’m so focused on piloting the Trident, I find it better to have a second set of eyes focused on examining the surroundings of the Trident.
I have not added the additional lighting yet. I’m building it right now. I have had a GoPro on the Trident before and did not experience any issues with how it moves though. My design for the added lights does account for drag it might cause, and should minimize it.
Yes, I think for any ROV pilot navigating caves/mines, getting your tether snagged or wrapped onto something is a concern. ALso in a mine I worry about causing structures to collapse and trap the Trident. I was just watching from the UNEXMIN project recently and though they are a million dollar project with seasoned professionals, I saw they too were worried about that as they navigated a flooded cave.
The best advice I can give is to proceed slowly and try to remember the things you had to weave around on your way in. When returning follow you entering path, use your tether as a guide. I often locate my tether first before heading back. In an emergency though, you can try pulling it back by the tether. It can take a lot of stress. When I’ve had to do that, I have someone else slowly pull it back while I pilot the Trident to keep it from the roof of the cave/mine or any of the sides.
If you have any other question please let me know. Also, I’m a caver and member of the NSS and local Grottos, so I’m very interest in you project. I’d love to hear more about it.
I look forward to hearing from you again!
