I don’t think that’s particularly bad. Logitech makes reliable input devices. I recall that the US Navy switched to Xbox controllers to control their periscopes on nuclear submarines and saved millions of dollars and found that people understood the controls better.
An off the shelf controller with several backup failsafes (they keep spares on board) is a perfectly reasonable way to do this. In such a cramped space, a hardwired or mounted helm would probably be continuously bumped or tangled.
Any custom purpose-built wireless device would just introduce more complication than necessary.
I’ve seen a video of US Navy using an Xbox controller (arguably for experimental weapon iirc but still). If it just works why overengineer it? I would be more concerned about that hull (scuttlebutt says it was just carbon over titanium frame, not titanium hull overlayed with carbon). However I guess we will have to wait until they find the boat to know the reason for failure.
Exactly. Making the controls yourself isn't necessarily better, as long as the rudders and engines are engineered properly. Some seperate (emergency) control might be a good idea, in case the Bluetooth fails. Just to get the submarine back to the surface.
The submarine is a one-off experimental one that isn't certified, hasn't been used a lot and dives deeper than almost any other submarine. That's enough alarm bells for me. Whatever they use to control the vessel is irrelevant to me.
I had a Logitech F310 which started malfunctioning, where the left stick's signal was always halfway to the left. Logitech's quality isn't what it used to be. I can imagine something like this happening on the submarine. Question is whether they had a replacement and if they even recognized that the gamepad was malfunctioning.
Fun fact: The Logitech Extreme 3D-stick is used in many professional systems, but those are reliable.
I don't see any issues with this as long as they had several fail-safes in case of hardware malfunction. US military subs us Xbox controllers because it's what people are comfortable with.
That is one of the least concerning parts of this lol, at least Logitech makes quality peripherals. If I had to choose a single manufacturer for input devices, it'd probably be them.
Except if they have made it to the surface and now they can't open the submersible to get new air. In theory they could be suffocating whilst bobbing along the surface. That is of course a big if they have somehow made it to the surface and not been spotted yet.
I couldn't imagine being in a cramped space 2.5 miles under the sea with 4 other people waiting for that time. Horrific comes to mind but I don't think there is an adequate word for it.
According to the BBC, the entire sub is bolted shut from the outside, so even if the vessel surfaces, the occupants cannot escape without outside assistance and could suffocate within the capsule.
Much has been made of thos controller thing and I think it's getting overblown. I can not speak authoritatively on the safety of the sub or the whole operation but I am aware that off the shelf video game controllers are used for a lot of things including even military vehicles. It's a good controlling device for many things. Yeh it probably looks a little worrying when you step in to something being manoeuvered by a videogame controller, it's not good vibes or optics but, it's not itself a reliable signifier of anything really.
Yeah, if they had not used an off the shelf part, then people would make fun of the janky controls with "levers and pulleys." The thing is a simple control scheme that's well understood and easy to learn. It gives inputs to an onboard computer which interprets pilot intent and steers the vessel (how ever questionable the vessel's construction might be).
Game controllers are used for all kinds of robots and vessels (often remote controlled) - so the fact they chose a controller does not weird me out at all.
Do I think they could have gotten a better quality controller? Yea, sure.
Do I think maybe a wired controller would have been better? My gut says yes, but I don't know their decision making process and the engineering challenges with running cables.
