The logistics of keeping them fed and watered, having trained handlers, and treating them for injuries are nontrivial. And they're prone to unhelpful reactions in a firefight. There are good reasons they've largely been displaced by motor vehicles. Combining the go-anywhere ability of legged propulsion with the advantages of motor transport seems like a good enough idea to merit study.

Much easier than the logistics of keeping a robot operational in the field. You don't care whether the Taliban captures your flesh and blood mule, but you really don't want them capturing your world's-most-advanced robotic mule.

Why? What are they going to do with it?

I think most other people use a single M to mean million, and k for thousand. Can't we just use SI prefixes or spell the numbers out instead of using some random alternate convention?

This is not a "random alternate convention", it's a highly used convention that you aren't familiar with. I wasn't familiar with it, either, until I moved to the Silicon Valley. Now I see it all the time.

I wonder at what price point the civilian market could support these? There must be a fair number of applications for resupply where humans (sherpas), actual animal mules or helicopters are required, ie, forestry, National Park rangers, science, recreation, etc.

> forestry, National Park rangers In most areas where these guys operate, actual mules are probably cheaper, and can be refueled with locally available forage. Not to mention they're more suitable for that kind of environment. Perhaps more 'extreme' environments where that forage is not available would be more suitable?

Walking the wonderland trail a few years ago I was remarking to my friend that in some of the most remote meadows at the top (7-8k feet) (https://www.google.com/maps/@46.9181125,-121.7649511,731m/da...) of the trail there were long stretches of very nice chat trails. He was saying what a pain it would be to bring the chat up and was trying to decide if it was ATVs or mules or whatever. I guessed helicopter.

We asked a ranger at the bottom. Answer: Helicopter. "They just dangle a huge bag of chat and we cut a hole and walk it along the path letting it pour out. Those mountain meadows are easier to do than the steep stuff at the bottom"

Can anyone in robotics weigh in on whether new approaches like pneubotics / otherlab [0, 1] make Boston Dynamics' super heavy/noisy/expensive robots irrelevant or not? That's what Saul Griffith has been saying at least [2], I'd like to hear an impartial take on it [0] http://www.pneubotics.com/ [1] https://otherlab.com/projects [2] "[...] we're the only game in town." 21:00 onwards https://youtu.be/gyMowPAJwqo?t=1263

Boston Dynamics' primary innovation is in the software/control design. The reason their robots are noisy is because they really haven't innovated a whole lot in the basic actuator design. That's not to say their mechanical design was easy, not by a long shot. It's super impressive stuff! Any new inventions that would make their mechanical design steer away from loud hydraulics would no doubt be amazing. However, with…

Thanks for your reply.

Is there much publicly available information about their software/control design innovations?

Hmm, maybe one might expect they would be hiring more mechatronics engineers to do just that? Or maybe there's still not much point for them because as you mentioned their focus is slightly different currently.

In my opinion, I don't think inflatable robots are very practical.(except for niche applications) One of the most important things in robotics is reliability, the more work your robot does before breaking down or needing maintenance the more money it makes you. In industrial robot arms the gold standard for this is a Mean Time Between Failures of more than 100,000 hours. That's more than 10 years of continuous operat…

Hey thanks for responding!

If the parts are cheap enough, might it not matter that they don't last the regular MTTF?

One of the arguments I've seen them using is that their robots can actually move faster than regular ones due to their weight advantage - currently I would guess accuracy is not as good though.

Another point I've been thinking about is that biological systems tend to combine the rigid and non-rigid per the needs of the organism, right? It seems that combining these techniques could also be interesting.

Perhaps reverse engineer it, find someone that can reverse engineer it, exploit it or others like it, expose every detail about it all over the internet, a number of potentially harmful things?

The Taliban are not going to have the capability to reverse engineer and produce their own copy, let along having the logistic capability of keeping it in the field.

It's a ridiculous "convention" and it's dubious what you mean by "highly used."

Using Roman numerals for anything is a waste of everyone's time.

Is it common for military electronics to have a self-destruct feature to protect technology secrets? E.g., when damaged beyond repair or abandoned in a hasty retreat, the hardware could ignite a little thermite to incinerate the electronics boards.

One of the stealth helicopters used in the assassination of bin Laden was so destroyed, but a part of the tail was left behind.

There are these things called "mules." They're quiet, can carry about 200lbs., and can refuel themselves as they go by eating grass and drinking water...

> and can refuel themselves as they go by eating grass and drinking water... Try finding 30 litres of water and 8 kg of grass ( plus a portion of salt ) per mule per day , minimum, in the mountains of Afghanistan. To move 90 kg of payload? There are many more efficient methods.

Actually they work great.

We (Air Force Special Operation) used them and horses to great effect in 2001 and the ANA have been using them before and ever since.
