The Xbox controllers are used to control the periscope which is not a safety critical device. Regardless, the navy uses wired controllers and did extensive testing and verification. This outfit didn't do anything like that; in one video with a journalist the bluetooth controller was a 'feature' because they could pass it around the sub.

Edit: consumer joysticks normally use potentiometers, which aren't great for deadzones/drift. For things like dust incursion reasons along it would make sense for any industrial/military device to be using hall effect based joysticks.

- kbenson 3y agoThe testing and verification is key. It might even be they were trying to lean on some work done by the navy on the Xbox 360 controller and that got switched along the line for the Logitech, losing one of the main reasons for using the original choice. In any case, I would hope they brought a spare (or had an alternative method to drive, even if cumbersome), as easy spares is one of the selling points of COTS parts (and long as you verify it's the real part and isn't a revision that looks the same invalidating your testing).
- danbolt 3y agoI wonder if using an XInput controller has a perk in that it’s relatively straightforward to find a second source if needed. Or, if one manufacturer isn’t working for them, they have a specification for controlling the periscope.
- jojobas 3y agoThe periscope is a combat critical device, lose control of it and the enemy will see you first and you're dead.
- rtkwe 3y agoIt's something that can be quickly swapped out if it does fail though being a wired controller, I'd put decent odds on this company not bothering to put a backup controller in their death tube. Also a periscope is less critical to combat in the age of sonar that can tell you bearing, heading and what type of ship often without the risk of surfacing and getting lit up on radar. Modern subs basically never want to surface in combat there's no need to take the added risk.
- jojobas 3y agoQuick replace is a fair point. Sonar completely superseding periscope is not quite as sonic countermeasures have been in use for decades. Also periscope depth is not surfacing.
- lyu07282 3y ago> this company not bothering to put a backup controller in their death tube the really strange part of that, is that the pilot was the CEO of the company. Like the Norfolk Southern CEO would never in a million years set foot on one of their trains of death. Anyhow they now heard sounds in 30minute intervals, so looks like they are still alive down there.
- rtkwe 3y agoI saw the same thing but some of the groups searching haven't heard that pounding since Monday from the places I read. Does imply it might not have been a catastrophic implosion but honestly that's one of the better ways to go in a submarine. Also there's a lot of noise in the ocean on some other sub rescues they thought they heard noises from the crashed sub but it was just from the boats looking for them.

- nonethewiser 3y agoI'm just imagining it running out of batteries. Then the user non-chalantly asks the pilot/guide for the spares. But they get a blank look. They repeat themselves. They must not have heard. They get a grimace this time and they suddenly realize what a precarious situation they were in all along.
- greiskul 3y agoThey had spare controllers. Part of the idea of using off the shelf components like this, is the ease of replacement. If you have a 100k controller, and it fails, you need to think how to fix it. If your controller costs 30 bucks, throw it away and change for a new one.
- cachvico 3y agoDo you _know_ they had spare controllers?
- greiskul 3y agoYes. In a 2022 interview with CBC, Rush added the Bluetooth game controllers were durable — “it’s meant for a 16 year old to throw it around,” he said, tossing the controller to the floor — and that they kept spares on board “just in case.” https://www.thestar.com/news/canada/2023/06/20/video-game-controllers-and-a-single-button-what-its-like-on-board-the-missing-oceangate-sub.html https://www.thestar.com/news/canada/2023/06/20/video-game-co... Also, the controllers appear to be only to control the periscope. Which is not a critical component of this submarine. Everybody is fixating on them, but that's not what caused them to sink/get lost. It was probably the rest of the shoddy engineering.
- prmoustache 3y agoHaving spares is one thing. The question is do they test spares on a regular basis, make sure they have been charged between every mission and rotate them to test battery life?
