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 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.
The navy uses it for periscopes, and training. Not piloting anything like this. This thing was definitely made as cheap as possible.
If it works it wo…
never mind.
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 feel like that’s the different between buying something and repurposing it and buying something and using it as intended.
In other words. Use the right tool for the job. A hammer isn’t a screwdriver just because you can technically hammer in screws.
A crescent wrench, on the other hand…
Imagine having to pilot a submarine with stick drift.
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.
Never mind the games controller. They bolt u in from the outside?! I’d never survive the panic attack
The submarine seems to have only one button for on/off… Did they think they can connect to iTunes there in case of some boot issues?
Hope they downloaded all the music to play offline
Should have used a Xbox 360 controller
That’s what we did at my job for industrial robots! These things are optimised to work well on Windows, which is at the core of many industrial computers… Build an equivalent with mouser or digikey? It’ll cost 10 times more and use the same internals…
They could’ve done a 360 and walked away…
If they did a 360, they’d still be walking forward…
I mean, Logitech makes reliable stuff. But shouldn’t they at lease have a player 2 MadKatz controller in a bin somewhere?
And it was probably the best built component of the entire sub
Hope they had a backup
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.
Don’t know why this is news. I have those Logitech controllers still in service and they still work after years. Generic controller input works with everything.
Probably was the most reliable thing on the sun.
If they are still alive in it what a nightmare they must be enduring right now, with only like 30hrs of oxygen left.
I feel like they likely lost pressure or some catastrophic failure and have been dead.
Or theogotec controller died and they drifted away and haven’t been found.
Either way it seems really bad for those inside.
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.
This story just keeps getting worse and worse.
