Robot Mule Put Out To Pasture By Marine Corps (nbcnews.com)

An anonymous reader sends word that the Marines have decided that Boston Dynamics' robotic pack mules are too noisy to use. NBC reports: The massive robotic mule developed by Alphabet-owned Boston Dynamics won't see combat with U.S. Marines. LS3 (Legged Squad Support Systems) was meant to carry cargo for weary soldiers in the field. Funded by the Defense Advanced Research Projects Agency, or DARPA, the robot was capable of walking with 400 pounds of equipment on its back. LS3 could run for 24 hours straight on a 20-mile mission across rough terrain. No controller was needed; it took visual and verbal cues from soldiers to find its way. So why doesn't the Marine Corps want to use it? The robot's gas-powered engine isn't exactly the stealthiest piece of technology.

what's wrong with real mules?

20 miles for 24h with 400 pounds of weight? Sorry, but those specs don't sound all that great compared to a real mule or pack horse.

Bioengineer a horse that can eat MREs and you'll have a quiet (but smelly) alternative to this robot.

No need to bioengineer, nature has already provided such horses. "She was fond of a wide variety of foodstuffs, entertaining the platoon by eating scrambled eggs and drinking Coca-Cola and beer. Food could not be left unattended around her. She was known to eat bacon, buttered toast, chocolate bars, hard candy, shredded wheat, peanut butter sandwiches and mashed potatoes."

Just use a better muffler???

I mean, seriously, its NOT THAT HARD to quiet an engine, they've been making diesels on subs quiet for 100 years now. Literally all you need is a better muffler, and add some sound proofing covering around the engine, maybe adds 10lbs at most.

Or, better yet, go with a small gas turbine, they're nearly silent, especially with a muffler, and can burn just about anything, diesel, gas, kerosene, you name it.

That's pretty damned idiotic throwing away a $30 million program because you didn't want to spend another few $100 on a muffler and some padding.

Stealth isn't only about sound, it's also about visual signature, heat output etc.

Yes, and I'm guessing this is all sour grapes.

Google doesn't do military applications. They bought Boston Dynamics and have told the military that they are not going to do any more military research. So, the military said, 'Well, we don't want it anyway, because it's too loud'. That gets Boston Dynamics out of the business and lets the Marines save face.
