I am excited to announce that today our customized BlueROV2 Heavy has been continuously deployed for a full year! Everything on the ROV continues to work great. People from all over the world have had the opportunity to remote control this ROV that is deployed to 900m in the Monterey Bay. Some of the components, including the aluminum enclosures, have been used on all previous deployments which have a combined submerged duration of about 2 years. I remember being warned by marine experts that they didn’t expect those enclosures to last more than 6 months.
I just want to give a shout out to Rusty (@rjehangir) and the entire Blue Robotics team on making excellent and affordable products as well as for the advice and assistance on this project. Thank You!
Congrats Are those lumen subsea lights? if so are they the old Potted version or the new wetlink version?
I watching your threads and threads about Tahoe I started down the path building a 900m capable blue but where I am now I find if I want sonar of any kind that is under 20-30k my depth is pulled back up to only 300m.
Hi Fred, those are BR lumen lights. We are using the wetlink version. A previous deployment of about 7 months used the potted version and worked but the potting will eventually dry out and crack which we found out during a tank test before a deployment and had to scramble to get replacements The old potted penetrators for the motors however did not hold up to testing and so we installed installed Subconn connectors for everything going into an enclosure.
Well if you ever come across a 1000m depth rated sonar that is less than $20k I would be interested as well.
We do have zincs on the ROV and the platform that the ROv is connected to. I have not noticed as much degradation of the zincs on the ROV as the platform. After previous deployments the only wear to the enclosures was a little white buildup around the tapped holes and the enclosure annodizing color changed from black to a dark greenish color.
Well I guess I jinx it because the ROV stopped communicating four days after our one year anniversary. The cause is not easy to diagnose remotely, but from what we can tell, it seems that the Raspberry Pi either died or is not fully booting up possibly due to a corrupted/broken SD card.
Lasting over a year continuously submerged far exceeded all expectations and I’m sure has set many records for both a BlueROV specifically as well as ROV’s in general. A big shout out to Rusty and the Blue Robotics team for making excellent products that just continue to improve.
