Yup, bio-fouling... I was researching that for a while. Everything likes to grow on your robot. We never tried getting past the two week mark.

Thought. Superabsorbent polymers to immobilize leaks. If it gets into the enclosure, it can as well be prevented from sloshing around.
|
Tony White 4:13 PM
The silicon dessicant sometimes does just this! I'll use a papertowel if I know I have a leak and need to mitigate it for a short time - preventing sloshing is absolutely key

Medical fields deal extensively with biofilms. Maybe they could have materials and tricks up their sleeves.

Omne usus duplicatus est. - love it @amok.mcconnell

there are solutions to biofouling, but unfortunately they are (literally) poison to the ocean, because they have to be!

Tony White 4:14 PM
copper in anti-fouling paints is being phased out in many places as a result

Thomas Shaddack 4:14 PM
THANKS for the Latin!

There was a study of shark skins by James cook university 20 years ago, on the use of surface microgrooves to deter barnacles on ships. It kinda works.

Copper metal? Textured teflon?
|
|
Tim McNerney 4:15 PM
@shaddack The marine industry has been dealing with bio-fouling forever. As Tony points out, it is the toxicity of anti-fouling paints that has become an issue more recently. I've never tried building a robot entirely out of copper. Is that disallowed too?
|
|
Tony White 4:16 PM
teflon - that's a lot of forever chemicals to put in the environment!
|
|
Tim McNerney 4:16 PM
@amok.mcconnel I looked into the "shark skin" patterning. Looks promising. No toxins.
|
|
Thomas Shaddack 4:17 PM
There are some newly discovered germs that eat the "forever" things.
|
|
Tony White 4:18 PM
I hope so!

Thomas Shaddack 4:18 PM
Thought. Controlled release of metal ions from surface by electrochemically modulated corrosion. Something like sacrificial anodes but the other way, and only when needed and where needed.

Tony White 4:20 PM
You're definitely an idea guy @Thomas Shaddack

The manufacturing process is basically an embossing of plastic using patterned micro-etched plates. It would need development to be adapted for odd curved surfaces.

For anyone still here, I just started this livestream. I'll try to monitor both this and that chat at the same time! https://youtube.com/live/3WR2bp3m36g

Thomas Shaddack 4:25 PM
Yup. Ideas are fun to play with! Often there are solutions already out there, just hiding in some seemingly unrelated field.

Thanks Tony, really appreciate the time. Great discussion, I learned a lot. Thanks all, see you next time

Random thought re the tether. Ukraine battlefield uses drones with optical fibers to work around jammers. Can the same tech be leveraged, possibly even as a surplus once the hostilities end and the toys hit the markets?
|
|
Thomas Shaddack 4:46 PM
Random thought. Could the autofocus be implemented outside of the camera, eg. in a module of the cockpit software?
|
|
Tony White 4:53 PM
I hope someone develops some sort of autofocus this way, yes, but it will be challenging!
|
|
Tony White 4:54 PM
Fiber optics have been used for many years by ROVs - typically these are a pricier option but provide waaaay more bandwidth
|
|
Thomas Shaddack 5:18 PM
see ya, was inspiring. thanks!
|
|
Tony White 5:20 PM
Sea ya! Thanks all!
