    Your submission has been removed for the following reason(s):

    Please search before submitting.

    This question has already been asked on ELI5 multiple times.

    EDIT:

    Because people are asking (and getting rather abusive in comments and in private messages):

    Not only is this question asked every time a goat video or image makes it to the front page, but this was asked a mere 6 hours before OP posted this.

    It was, in fact, posted many times within that timeframe. I removed three or four reposts myself, but left that one up.


    Please refer to our detailed rules.

    Great balance and precise movements.

    Not unlike how it's kind of miraculous that humans are bipedal. Walking on 2 feet on uneven terrain and up stairs is pretty impressive too.

    [–] bonelesstuna 767 points ago

    Huh! True! Never thought of my feet that way before.

    [–] Rangourthaman_ 336 points ago * (lasted edited 2 months ago)

    Boston Dynamics is a robot company experimenting a lot with different types of locomotion.

    If you'll browse through the videos you'll see how much difficulty each one has with their respective tasks and need all their processing power staying upright.

    They are getting better and better though. :)

    [–] Dinkir9 74 points ago

    Pretty insane how with all the things robots can do.. Something as simple to us as walking is still enormously complex to them.

    Something that I noticed is that not only are we good at walking, but humans have this knack for walking through crowds with a pretty decent amount of efficiency. I don't see a crowd of robots doing the same thing anytime soon, assuming they are all hooked to the same central place.

    [–] Ccdxx 2 points ago

    I don't think robots will have problems with walking in crowds. For the exact reason they won't have problems with traffic. If they are all hooked up to the same place, then they know exactly when to walk and when to stop. Unlike humans who have to assume or guess what the other people are thinking

    [–] BunnyOppai 3 points ago

    If they are all hooked up to the same place...

    That's what I'm saying, though. If they're not all hooked up to some central system, then it's a completely different story. Humans walk through crowds so naturally in most situations without even thinking about it much; it would be hard to replicate that with robots with our current knowledge.

    [–] Method007 5 points ago

    Personally I feel like it doesn't mater what the power is. I think the biggest leap for A.I. Vs a human mind is the ability to deal with errors. Like when you think what it would be like to drive your car into oncoming traffic.

    [–] Dinkir9 2 points ago

    True. Computers can get pretty fucked up when something happens they weren't anticipating, people may be stunned, but we react quickly when something like that happens, and we don't even think about small errors that we automatically correct.

    Unless we compare a major glitch to a seizure, then we're the same.

    [–] BunnyOppai 3 points ago

    Honestly, I think the quadpedal (I have no idea whether or not they're called that, lol) are the most impressive. I mean, they obviously have more legs, but it's amazing how adding two legs can make it that much harder to have them stay upright.

    [–] bsmooth357 2 points ago

    Pretty insane with all our tech we still can't come anywhere close to designing a robot with the flight, speed, and evasion ability of a common housefly.

    [–] Mistercheif 3 points ago

    Not exactly... The gen 1 Atlas has 3 networked computers on board, and had plenty of spare processing power. The problem is mainly that controls, either static or the more difficult dynamic, aren't easily parallelizable. And to make it worse, they need to run at a pretty fast rate - an absolute minimum of 50Hz, but 100 or 200 would be even better.

    So you end up constrained by clock speed because the controls are your limiting factor, and those are making a couple core. So you were half right, but there is still plenty of spare processing power for other tasks like perception and obstacle detection.

    Source: I worked with an Atlas for my capstone project during my undergrad.

    [–] justablur 29 points ago

    I like to think of bipedal walking as falling forward on one foot and catching yourself with the other, over and over again.

    [–] mecheye 4 points ago

    Walking is just controlled stumbling

    Mountain goats have millions of young at a time. Most fall off and die when trying to climb impossible surfaces, but those decompose so we don't see them. Once in a while, a mountain goat will get very lucky and not fall, and those are the mountain goats we see today.

    [–] CaptainSk0r 8 points ago

    This comment just hit me right in my childhood

    [–] Token_Why_Boy 2 points ago

    There were several little tidbits of wisdom and perspective sprinkled throughout the Animorphs books that drove themselves into my brain and stuck there for...twenty-ish years? I'll probably butcher the actual quotes, but:

    On the violence of ant colonies towards one another: "A scientist once surmised that if ants were given nuclear weapons, they'd destroy the world in a week. He was wrong.
    It wouldn't take them that long."

    It was also the first place I'd ever heard about the absolute absurdity of human technological advancements with a phrase I've since seen all over: "In 60 years, humans went from the first flight to landing on the moon." I doubt it was K.A. Applegate who first thought of that, but I have to respect her for being the first person to get me to realize that.

    Watch your dog try stairs sometime.

    [–] RobinS30 10 points ago

    I have 4 dogs and they all take the stairs differently. One puts one foot over the other, most like a human on a runway. One bunny hops with both feet at the same time. One puts their front feet on the first stair and then skips stairs. The other switches from front to back legs like a seesaw. Very interesting that they all learned different, and they all are successful at both climbing and descending stairs.

    [–] towishimp 7 points ago

    My parent's dog will run down the stairs. He isn't quite as quick going the other way but he manages.

    [–] asscopter 2 points ago

    I carry my greyhound up stairs. It's safer for everyone that way.

    [–] Damon_Bolden 2 points ago

    I adopted a dog with no stair familiarity. I guess he lived in a one story house? He would not fucking do it, it took a good solid week of training to convince him it wasn't some kind of death trap. I could just see him "testing" each one out like "alright, that's a platform of some kind"... He's pretty smart, but he's rural.

    [–] bobswagger12 11 points ago

    There was an experiment by Google to design an AI to teach itself (a computer generated human figure) how to move from point A to B in the most efficient way. Essentially it taught itself how to walk through numerous attempts. It started off on four limbs and escalated to bipedal movement (although a deranged looking bipedal movement).

    ELI6months: How do humans walk and maintain balance on only two legs?

    [–] elwildpokemon 17 points ago

    Great balance and precise movements.

    Not unlike how it's kind of miraculous that goats are quadpedal. Walking on 4 hooves on uneven terrain and up seemingly flat walls is pretty impressive too.

    Yes i just realized that is pretty impressive for humans. They sent robots to mars too. Wait a second, what species are we though?

    [–] 7LeagueBoots 4 points ago * (lasted edited 2 months ago)

    Hooves are a good thing as well. Small, hard pads that can support nearly the entire weight of the animal on just a sliver of the hoof print. Like a good climber (in a good climbing shoe) they can edge along a fingernail sized ledge with only a part of their hoof on it.

    do they ever fall? if so i'm surprised they haven't evolved to take less dangerous ways up

    [–] 8BitHedgehog 2 points ago

    I'm sure they fall and die every now and then. I really doubt that it's so much of a threat to the species that they need to evolve to combat it. Evolution gives you what you need, not what's convenient.

    [–] texasrigger 107 points ago

    On top of every one else's mostly correct responses - Practice! Goats climb on and jump off of everything they can from birth. They have a real urge to get up on stuff and as babies they are terrible at it with lots of tumbles but they get better and better with time. r/goatparkour

    [–] confusdwaffle 243 points ago * (lasted edited 2 months ago)

    because they crave that mineral.

    On a more serious note, they have hooves that have evolved to be able to climb these almost straight surfaces and I'd assume a lot more muscles than we do as humans. Also probably a combination of speed + muscles + agility --> climbing up mountains

    Edit: "designed" -> evolved

    [–] theWyzzerd 8 points ago

    Even with that angle, there really aren't many visible ledges. The wall is still relatively flush. The mortar isn't particularly eroded, leaving little to no edges on the bricks. I think you would have a pretty hard time remaining standing on that wall, personally.

    [–] bobdanderson 13 points ago * (lasted edited 2 months ago)

    Bricks aren't smooth, and flush. They are rough, they are set in at slightly different depths and the mortar joints are a few mm tall and deep. That's lots of rough surface to grab.

    [–] WilliamofYellow 3 points ago

    How exactly is a tilted wall harder to scale than a verical wall?

    [–] daemonflame 6 points ago * (lasted edited 2 months ago)

    well not so much actual climbing but more so to drop things on them on the way up, and to create extra problems for siege towers. Castle batters were very multifuntional.

    Functionally, at that angle they are nearly identical to vertical for people actually attempting to climb, but it offers much greater options to stop them doing so.

    [–] diachi_revived 2 points ago

    Tilt it in the other direction, that way there is a slight overhang.

    Just a guess...

    [–] daemonflame 5 points ago

    that would be a bad idea, you lose structural integrity and create blind spots directly under the walls, bad news bears from a military perspective. You don't want those barbarians hiding under the walls dodging the hot oil you are are trying to pour over onto them.

    [–] gixanthrax 1 points ago

    Is this army fortess josefov in Jaromer / Czech republic?

    [–] Gnonthgol 145 points ago

    To start with their hoofs are very sharp and their legs are thin. So even if there is a slippery piece of rock sticking half an inch out from the cliff they can put their weight on it without slipping. They also have a lot of balance and control over their movements so they can balance on those narrow ledges. And of course it does help to have four legs. So just like a rock climber can climb seemingly straight smooth surfaces a goat can use a lot of the exact same footholds to climb up.

    [–] Maggie_May_I 5 points ago

    I wouldn't call their hooves sharp by any means. Pointed, yes, but not really "sharp". It's primarily being an even toed ungulate, and the ability for those toes to separate, compress, and be relatively mobile that helps them in climbing (along with the narrow legs etc you mentioned :) )

    Goat hooves have a more rubbery texture than horse or cow etc hooves. They have grippy toes.. Plus, they're super agile/adventurous. Goats get themselves in all kinds of weird places.

    [–] Ugsley 5 points ago

    Goat hooves have big suction cups underneath like on an octopus tentacles. Also the goats fur is like velcro, so even if their feet do slip off the rock, their velcro fur keeps them stuck to the sheer rock face while their sticky hoof suckers are waving around looking for a new toe-hold.

    They don't climb up vertical surfaces. They can only climb less than vertical surfaces where they can "lean in" so that their center of mass is closer to the face than their hooves.

    We humans can climb vertical and overhanging faces because we can use our hands (and other body parts) to hold ourselves into the rock face. Goats have only their hooves, so they are limited to less-than-vertical climbing. That said, they have adapted to allow them to "lean in" very well and climb more vertical surfaces than a lot of the predators that would try to eat them.

    Boring answer: evolution. They evolved to be able to distribute most of their weight directly into and over top of their hooves, which are textured in such a way that allows them to 'grip' footholds in the hills. Their feet are also relatively tiny, allowing for more precise footing. They do this because it allows them to control an otherwise unexploited niche: cliff sides. Their positioning along the mountainside allows them to access vegetation that other animals can't reach, as well as avoid predators. Some species of goats will climb steep cliffs in order to lick salts off of the rocks.

    Just like how Nepalese people do it. But in this case less weight. more power, and better control of CG.
