That Logitech joystick model was a staple HID (Human Interface Device) and wireless peripheral for many robotics researchers and corporations. Pairing and range was better than any 2010’s Bluetooth, and more compatible than OEM or hobby grade RF controllers. So many ROS projects used those. If both Xbox and PS DualShock controllers get cought amidst similar public ridicule, then we’ll have nothing left! 🎮🙃
I remember using them in my high school robotics club. And honestly, I think the controller was probably one of the least sketchy things about the sub. Lots of fields use game controllers to handle equipment since they’re well designed for that. There were many other things that were far worse.
Yep, I’ve seen reporting of Navy’s using them for controlling periscopes on submarines (now that most are drive by wire), or Air forces using them for piloting drones, as well as for teleoperated robotic thoracic surgeries.
The widespread user familiarity and benefits in transferable hand coordination skills with common gaming based HID economics is hard to refute. Although, I’m guessing the market for safety certified joysticks will uptick.
to be fair no one in their right mind would use a wireless controller for something like a submersible
I mean they are all using first party xbox controllers, not a logitech knockoff that sucked even 10 years ago compared to first party 360 controllers.
That wasn’t the dumb part of that submersible. Game controllers are actually really good at what they do. The dumb part is that it was built like an airplane.

Honestly, I wasn’t aware it was wireless. I wonder if there was a backup system. There has to have been a normal computer interface, at least, so you could check gauges and so on.
Although, if it randomly collapses on you at the speed of sound control is a moot point.

Truly, a Fyre-festival level of wealth-fueled stupidity.
An airplane with no safety checks
Built like an airplane out of materials that were past their shelf life even for airplanes:
Only one thing concerned me: He said he had gotten the carbon fiber used to make the Titan at a big discount from Boeing because it was past its shelf-life for use in airplanes.
I asked him if that weren’t a problem. He replied that those dates were set far before they had to be, and that Boeing and even NASA had participated in the design and testing of the Titan.
It is a conversation I have thought about a great deal over the past week.

Also, Boeing denied being involved, and NASA stated that they had given advice but not been involved in testing:
Yikes.
and that Boeing and even NASA had participated in the design and testing of the Titan.
They keep repeating that, and I was wondering WTF that means. Neither of those people have a mandate or any experience with submersibles (at least, I think, maybe there’s a weird Boeing spinoff). They could contribute just to the basic structural considerations, but they’d need to take resources away from their actual jobs for that so they wouldn’t.
Fucking hell, that’s horrendous
Ok, but how many of those projects will result in death if one of the thumb sticks gets stuck or if the Bluetooth loses signal?
If it results in death when the controller stops working, you have a serious issue with the system architecture and should work on that instead of trying to improve the controller.
Out in the wild? Perhaps quite a few. For example, for teleoperated robotic thoracic surgeries, I imagine medical grade HID should mandate safety certified hardware that doesn’t rely on electrically noisy mechanical potentiometers, subject to Dead zone drift, or non-deterministic dead man behavior under failure modes. Although I’m certain there’s various reasons not to use hall effect sensing devices even within the same facility as MRI machines.
Batteries in the controller run out and you forgot to bring any more double As
There’s so many input devices that have drivers baked into the modern Linux kernels that I’ve not had an issue using any device in the past 10 years (wired or wireless/Bluetooth). Sometimes that device requires windows for some companion software (like to control rgb), but input functionality still just works.
An old game controller is still more reliable than your in-house button board

I just feel like maybe you shouldn’t use Bluetooth when it’s life and death.
