OpenROV shared the results of their June 2016 underwater expedition to locate and robotically explore the wreck of the S.S. Tahoe, currently sitting at a depth of 150m in Lake Tahoe. Back in 1940 the ship was intentionally scuttled in shallow water, but unexpectedly slid to a much deeper depth. OpenROV used a modified version of their new Trident design to dive all the way down to the wreck and take a good look at things, streaming it over the internet in the process.
We previously covered the DIY research vessel that was designed and created as a floating base station for the ROV while it located and explored the wreck, and now the results are in! The video highlights of the expedition are below, as is a video tour of the ROV used and the modifications required to enable it to operate at 150m.
Underwater robotics is an area in which hobbyists regularly experiment and innovate. We’ve seen a smaller-scale robot trying propeller-free propulsion, and we’ve also seen the other end of the spectrum with multiple custom-designed propellers and ducts. The hardware is still only half the battle, so it’s really exciting to see the results of actual, practical use.
