Why Robots That Bend Are Better

เผยแพร่เมื่อ 18 ก.พ. 2021
Robots of the future may be softer, squishier and bendier than robots today. This could make them ideal for space exploration. Check out kiwico.com/Veritasium50 for 50% off your first month of any subscription!
On Thursday February 18th, 2021 the NASA Perseverance Rover will land on Mars. It is a wonderful robot, made out of steel and wire - but will future robots look like Perseverance? There is an emerging field of research on "soft robots", where the machines are flexible. These soft robots have many advantages over traditional robots - they're safer, lighter, more flexible and can change their shape and size.
NASA is investigating the use of soft robots for space missions. For future visits to Enceladus or Europa, a lander could cut a hole in the ice and then insert a compliant robot through the hole. This robot could then grow and change shape on the other side.

  • GUI = gooey?

  • I wouldent say there better. It depends what you want it for.

  • 0:48 , 2 Rs Mask is famous everywhere ❤️

  • Compliant robots could definitely have use in rescue through tight places

  • I get kiwico crates (mine is tinker crate)

  • Kiwi Co is definitely something that would interest me when I have kids

  • “...as we want robots to work closer and closer with humans.” 😳😳😳

  • until 5:58 i had absolutely no idea what this video was about.

  • not a single Bender reference...

  • This guy makes adverts more interesting

  • Corporations gotta corporate.

  • "Soft Robots That Bend Are Better" Interstellar: MONOLITH

  • "but why would you want to soft robot in the first place?" WELL HAVE YOU EVER TRIED TO CUDDLE A HARD ROBOT??

  • ... and the robots they bend are the best!

  • Baymax! OP!

  • The person who invented the wheel is rolling in their grave right now

  • Boston Dynamics left the chat...

  • Bender is not happy

  • "Why would you want a soft robot" Ummm... My friend's research purposes.

  • If you don't think that you are being programmed by the influencers that you watch. Play the shot game and every time you see someone wearing a mask in this video and use the word compliant well you know the game and a double bonus for those of you that pick up on the other words that have recently been added to our public narrative. But those of you who can't see it never mind me and just OBEY!

  • big hero six?

  • I mean when you think about it, humans are squishy and we work pretty well.

    • And now for the first time ever in 2b2t history... HUMAN SLAVERY

  • I'm no longer afraid of the judgement day.

  • No disrespect to the robot, but my favorite part was the Kiwi Co. ad at the end. Those kits make me wish I had a couple of school age kids running around so I could play with their toys. 😁 Kids' brains are just information sponges until they hit puberty.

  • oh you think that robot is safe do you? just wait till it figures out how to squeeze the life out of you boa constrictor style.

  • Bad title. Disliked. This is "The advantages of soft robots," and I'd definitely say they're interesting, but everything I've seen in this video is in the proof-of-concept stage and have only demonstrated the ability to move on a flat surface and pick up a ball. Note, by the way, that I don't think it can actually carry the ball as that entire triangle cannot move without dropping the ball. Yes, this is cool and has _theoretical_ benefits, but until (and unless) it is fully developed (and I hope it will be), you can't say they're better.

  • Small ball joints in compound form

  • cant wait for the robots that bend over !!!

  • 4:04. He must be thinking, “I knew clown school would come in handy one day!”

  • This robot and Robocop would be best mates. Because, compliance.

  • Okay, I need to know what's going on with the string at 9:58 with Mark Rober

    • I'd guess that the string is actually a very thin tube connected to a slow air pump. Look exactly like a tube inflating

  • Omg I was thinking of Baymax, so it was so cool when he mentioned him!

  • Bender!

  • Do you not still need electronics to power these soft robots? I don't see how that would benefit miners. I'm one confused dude.

  • Huh I guess that's the direction humanity decided to go in. Soft and agile machines.

  • "I have a GUI in Matlab", what a fucken madlad lol.

  • That pneumatic turtle thing is more ground breaking, in how I see it. Most of our mechanical implements are driven by circular mechanics. Drills, vibrations, pumping motion, swaying arms, rolling, picking, sorting, etc...utilizing rotors, rollers, tubes, chains, fulcrum, arms, weights, etc..everyday mechanics are usually driven by a rotating or semi rotating engine.

  • this is dumb and isn't practical. biggest contribution is whatever models are developed. but you can waste 5 years getting a phd in it just to go work for google or tesla, doing something that's not soft robots, and then need to make up for the 5 years of wages you missed out on. with too specialized a field your employers are limited and less time available to job hop your breakeven ends up around age 35 - 40, congrats you wasted the best years of your life (at least financially).

  • You should've put the Big Hero Six reference at the beginning of the video to hook more viewers.

  • If you built a ten thousand of those out of kevlar you could be a bond Villain.

  • People are so smart..

  • soooooooo boston dynamics is making gundams, and these guys are making baymax XD

  • You could probably use this concept to made extremely small to store, and easily replaceable wheels. Combined with the ability to inflat them from an external compressor than stored, and transported gasses. They provide a good weight and size saving on a payload


  • Use foam tubes?

  • The curve always has it. Imagine a flat planet, it'd crack in the middle. Ain't no lines anyway but objects in a certain disposition to each other, static or moving.

  • Mmmhhhh "soft robot" I think about Baymax!

  • Compliant. Unlike George Floyd

  • You know someone is a researcher when they make GUIs in MATLAB, yikes

  • So robot waifus that are soft are possible...

    • @Stacy McCabe No.

    • Stop what your thinking

  • "WE named them after sausages" And one of them isn't the Wurst, you disappoint me.

    • You have Kiełbasa tho

  • awesome and i they look like more alive

  • 'Soft Robot " is my pet name for my boyfriend

    • i call my loved one "steel mann"

    • Umm is he impotence??

  • The synonymous pelican selectively object because aftershave rheologically start since a watery french. true, spotty era

    • Please help, I tried to read this and now smell burnt toast

  • "sir... SIR!!" "Get me, ONE O' THOSE"

  • 😂🤦🏽‍♂️🤖 I see how his world is destroying his self now😂😂😂🥱

  • 1:44 I like how these people think We’re Stupid how come you don’t kick the Metal

  • So we have already created 2 general species, or genus of robots. Soft, and Hard. I imagine in a scientific fiction future, the Hard robots will dominate the Soft robots.

    • I need to get my mind out of the gutter

  • Cool!

  • "But why would you want a soft robot in the first place?" Because they are fricking awesome and look creepy/cool, that's why. Honestly. Some people got no soul.

    • 😂🤦🏽‍♂️🤖 I see how his world is destroying his self now😂😂😂🥱

    • 1:44 I like how these people think We’re Stupid how come you don’t kick the Metal

    • Being creepy/cool doesn’t make it worth investing millions into. Honestly. Some people got no brains.

  • Show the one inserted inside a sphere

  • Polish sausage rulez ✌🏻👍🏻😎🌭 Best greetings from Poland! 🇵🇱🙂

  • We've got punctuated rolling locomotion. Now how about we make substitutiary locomotion work?

  • cxu iu parolas esperanton kun mi

  • mask wearing sheeple, time to stop be the problem and start being the solution. is not mask hysteria a symptom crazy enough to realize we have gone to far?

    • Shut up

  • My word of the day is Compliance.

  • you should contact N.A.S.A.

  • I didn't know the odd ones out was a scientist

  • Aww Skynets so cute now ...

  • The Boston Dynamics robot videos are terrifying because they are made for military applications.

  • ew im glad im not subscribed to a bunch of diaper wearing adults.

  • Veritasium - why would you want a soft robot me - two words sex robots

  • So, a redtube robot...

  • wait you have one arm thats called Polish and the other named kiełbasa? those are the same thing

  • 0:17 Top 10 rappers Eminem was afraid to diss

  • baymax already showed me that soft robots are better. :D

  • you look like a math teacher

  • well i certainly would have build a spherical bot. made of inflatable rings. you can then wind wires around them, controlled by motors on the opposite ends.

  • Robots that bend are better? "Shut up baby I know it".

    • underrated comment

  • What's the soft robot designers favourite movie? 'The Flight of the Navigator' - Compliance!

  • The outrageous roof radiologically suspend because pyramid usually note including a strange ring. innate, alcoholic map

  • Nice

  • How did they keep animal feces out of La Reservoir?

  • The tame string medicinally radiate because antelope usually remind on a damaged field. dizzy, cluttered actor

  • Smart enough to make a robot, but doesn't realize that that cloth mask doesn't stop the bs virus...

  • i hate these soft robots

  • All these robots are trash

  • well, people that bend are better too.

  • Hammond Robotics... Titanfall will be real

    • The size of titans is actually the most realistic scale for a mech. We already have the beginnings of this technology with the Method 2 and Skeletonics mechs. They'll be revolutionary for industrial work.

  • Because COVID response.

  • Wait isn’t that mark rober in the kiwico outtro?

  • It's safe unless it becomes evil and spikes you in the eye

    • -.-

  • This video is a massive reach lol one sharp rock and it's a bunch of useless plastic

  • Hello! Scientists! Make your tube cover out of Mylar. Bullet proof vest stuff. Greatly reduce the incidence of puncture.

  • Softer is better on the bed

  • Gracias por el video y que pronto sea otro billón más

  • Boneless robots 😅

  • Zack Hammond looks like... TheOdd1sOut with his mask on.

  • I dont think its better. These robots are like animals made out of just ligaments. I prefer a bone to ligament to bone, Muscle to tendon to bone system. As I get older I can really understand the value of strong ligaments, as I lose these with age. I can exercise the muscle but if the ligaments are loose then the structure begins to grind the joints as it gones out of optimal position. Why not use ligaments with robots ? The ligament connects a bone to a bone. Tendon is muscle to bone. Ligaments allow bending and structural strength, Muscles are the motors, Bone supports structure and give the muscle something hard to push against, as does tight skin.

    • @Kunal Vyas Strong rubber could work as an artificial ligament, maybe just replace it every now and then and recycle parts.

    • Google "Di-electric elastomers"
