pretty ingenious mechanical design. This could revolutionize robotics since it seems to require so little energy to get it going. I can also see this as a pretty cool alternative to wheel chairs, and possibly a more convenient method to move around in.
I think the point of this walking device is that it can walk without power or sensors and keep balanced. Not useful by itself, no, but if you're going to have robot systems that walk instead of being on wheels, it would make sense to have a passive backup for when a real person-shaped machine loses power. This is kind of like how helicopters can "soft land" from rotor momentum even if the motor stops or is out of fuel. Passively mechanical, but a backup plan.
leggs like these are more flexible than a wheel, u are right. However if these leggs are equiped with a motor and batterys, it uses more energy than a wheel to do the same distance.
It probably shouldn't count as a robot. However, I think the point of building this thing is to show/test our understanding of the dyanmics of walking. A more advanced version has been build by Prof. Ruina's group at Conell. Wheels are useful but legs have their advantages in many places.
It might spawn better mechanical knees and lower energy cost for walking robots :) If a robot can shut off most of his motors, or even recharge batteries while walking downhill, imagine the potential in terms of autonomy !
Yeah, but attach this to an android and suddenly you got a robot that can walk down slopes while recharging the battery for walking up a slope, hence a vastly longer battery life essentially making androids more feasible as a whole.
And this ladys and gents is what was once called a slinky. No power, goes down slopes, moves on its own energy from just a push. EVERYONE LOVES A SLINKY!
Me gusta! I love stuff that does "amazing things" (eg. walking) just in pure and simple mechanics without tons of sensors and whatnot ... way better take at building robots than starting by throwing in a huge load of high-tech to start with (not saying that sensors and motors can't enhance it, but it adds complexity prematurely)
@TheLivirus This robot leg system does *only* walk down a incline. The shots where it is walking horizontal is when its on a motorized treadmill. Also nobody mentioned the law of thermodynamics, sorry.
To be fair, you could still do the same thing with a wheel. =P That's essentially what regenerative breaking is- turning kinetic energy that would otherwise be lost in to electrical energy that can be stored.
yes but legs are still more flexible than a wheel, i mean osbstacles. i guess they can combine this with an actual motor to be used if there's elevation, so as a robot it can save a lot of energy if we're going down. the problem of modern robots is that they require a lot of energy and battery packs suffice only like for 1 hour
If it doesn't have a motor or anything, is it technically not a robot? Because all you need to do is push it. It's like pushing a slinky down some stairs.
Jozsef NGJ autonomous meaning it keeps going? In that sense, a slinky going down an endless staircase is a robot. A ball rolling down an endless hill is a robot.
@@austinsharpe8157 Ok, how do you define it then? Also : autonomous = denoting or performed by a device capable of operating without direct human control
@juankis3103 The robot is effectively walking downhill. So yes, if you have a 15 km long slope it would keep walking. It won't work on flat ground and it definitely won't work uphill.
Definition of Robot: "A re-programmable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks." This isn't re-programmable or programmed and only preforms one task, there for this is not a robot. It is nothing more then a over scaled desk-toy, if this is a robot then 'Newton's Cradles' is also a robot.
I like to make canoe portager like that, with four sets of two legs. Should work with bush terrain +/- 15% grade. Maybe robot will have wheels for feet.
@archon808 "This robot leg system does *only* walk down a incline." I'm sorry, I assumed it was walking on flat ground. I mean, what's special about making something go downhill? A coconut goes downhill. The first law of thermodynamics got involved the second I thaught you were saying it gained its energy from declining, but at the same time maintaining at groundlevel. But if it indeed does go down a slope like you say, the law is not broken.
@JZGreenline In english: Every action has a cost, if it does something then it used energy that it will run out of eventually. Thus why you eventually come to a stop on a swing-set ;P
I totally love passive walkers. This one doesn't look very stable and using the treadmill is cheating. You should be able to give it a push then it should walk as long as it has inertia. (Just like wheels) The much to heavy feat on this design burn up all the kinetic energy by accelerating and decelerating mass every step. But it does look nice :D
ok think, they could use this technology and create friction pads that charge batteries for when the robot needs to use power to walk. Yea. A self - recharging robot, no need to charge it or have an external power source.
@sky6035 @overleveled It's not meant to be used only downhill, is that what we use wheels for today only? It's only a functioning prototype, applications are shown which could assist people in walking if they can't support themselves.
you clearly do not understand that it will be add as an extra feature to gain more energy when going down hill, but robots are not going to generate energy just from that, the idea is for when robots going down hill they will generate extra energy from this mode, and not use so much from batteries, the perfect alternative is to have magnetic electric energy generators that have magnets oppose each other by spinning and generating energy, the more energy the robot requires the faster magnets spin
@SaltyBrains it isn't free engery. It's just converting gravitational potential energy into some other potential energy, most likely chemical (battery).
@archon808 If it was in constant decline it would be running down a slope, trading potential energy for forward momentum. This is appearently not the case as it walks on horisontal surfaces. It does not break the first law of thermodynamics, I'm sorry.
Beautiful science, a machine developed anthropometric design with high technology, which offers perpetual motion is possible but not yet. Leonardo Da Vinci had a dream to invent a perpetual motion machine, but not so far today ... The invention of this video is comparable to a wheel [not up yet ...] But it will be possible to break the law of thermodynamics when these movements generate their own energy. Prosthesis is then applied to human, robot building, transportation of freight.
I am from the future, and this is the start of skynet. we must band together as humans and destroy the machines starting with this perpetual walking robot
thats the smoothest mechanical locomotion i've ever seen.

when physics exhibit it's ultimate glory in the form of engineering
They stole Squidward's walk cycle
The real question is.......can it play golf with those legs?
🤣
squidward is that you

This is super cool. What practical uses would it have, though?
Its deceptive simplicity equates to true genius
@mcgrever9123 The point of the device was to find more energy efficient means of transporting. It could be adapted to work with prostheses and such.
This have quite a potential for efficient locomotion.
a simple machine but astounding.
The old guy behind the treadmill has his checkbook at the ready.
To be fair, you could still do the same thing with a wheel. =P

how is it a robot without electronics and motors? wouldn't you call that a kinetic sculpture?
If it doesn't have a motor or anything, is it technically not a robot? Because all you need to do is push it. It's like pushing a slinky down some stairs.
It has to be autonomous to be a robot.
Jozsef NGJ autonomous meaning it keeps going? In that sense, a slinky going down an endless staircase is a robot. A ball rolling down an endless hill is a robot.
@@austinsharpe8157 I don't know. If I throw a rock and it keeps on going does that makes it a robot?
Jozsef NGJ with your reasoning, yes.
@@austinsharpe8157 Ok, how do you define it then?
Also :
autonomous = denoting or performed by a device capable of operating without direct human control
If squidward was like Darth Maul he would need these legs
It's nice but a wheel does the same thing ... For people who don't get it : it is going down a slope (down a hill) in the video.
Why does the guy keep tweaking it? What is he doing? Can this one also walk 13 hours or is this one different and for what reason?
Look up the video called walking thing same principal works with forward momentum, or the potential energy of an incline.
I think they are... *puts on sunglasses*... reinventing the wheel.
Yeeeeaaaahhhh.
Keep in mind that this robot has a third leg :D
that's how squidward walks, jussayin'.
cant we use this to power low friction treadmills to produce energy
@RobSellsTacos you make a good point that i wasnt thinking of but id still like to see if they had treadmills that had almost no friction
@TheLivirus It isnt using the energy from the push. It is on a decline, and is powered by gravity.
@juankis3103 The robot is effectively walking downhill. So yes, if you have a 15 km long slope it would keep walking. It won't work on flat ground and it definitely won't work uphill.
that was on a regular surface..... irregular terrain is another pair of shoes (or legs for that matter)

@JZGreenline You dont need a treadmill, you could just hold the robot in place, and add wheels to it's feet
What exactly is the accent of the first man speaking (at 0:04) ?
Hey look it's squidward
напомнил мультфильм "Тайна третьей планеты". Наши мультипликаторы лет 20 назад такое придумали))
I like to make canoe portager like that, with four sets of two legs. Should work with bush terrain +/- 15% grade. Maybe robot will have wheels for feet.
I'm pretty sure this will only keep walking if it has potential energy (aka a hill or treadmill). Not a perpetual motion machine.
Why isn't this demonstrated on a floor where no energy is being imparted after the initial push?
@archon808 "This robot leg system does *only* walk down a incline."
I'm sorry, I assumed it was walking on flat ground. I mean, what's special about making something go downhill? A coconut goes downhill.

great now we can have robots that do not require electricity, but yet they produce there own energy, I like that :)
How could it change direction?
I would like to see where this idea leads.
+ikinamo - These robot legs can help the people with any disability!!
@marcotnp
Correction:
*Energy Efficient* robot soldiers
why not use the motion to generate electricity?
@JZGreenline In english: Every action has a cost, if it does something then it used energy that it will run out of eventually. Thus why you eventually come to a stop on a swing-set ;P
Best Golfer EVER
@persevere67 = no, it's using the energy of the treadmill - it's just utilizing it efficiently.
この下り坂の高低差に相当する分だけ、ふくらはぎの筋肉を使って落差を作ってやれば、自励振動で二足歩行するロボットの完成ですね。

You know what else can move forever going down a incline? A wheel.
i love it!
can it als be used in a electric humanoid robot?
@sky6035 @overleveled
It's not meant to be used only downhill, is that what we use wheels for today only?
It's only a functioning prototype, applications are shown which could assist people in walking if they can't support themselves.
um is this not perpetual motion?
without accelerating? Without a motor? Without breaks? Without any other parts?
if it's going down slope, why not just use wheels? no need for a push at all.
that would be cool prank for halloween
THE GUY PUSHING LOOKS LIKE A ROBOT TOO ......LOL !
just like a wheel rolling down a hill, but this is still very cool

@SaltyBrains it isn't free engery. It's just converting gravitational potential energy into some other potential energy, most likely chemical (battery).
uh, the treadmill is powering it.
This definitely has applications, if a robot used this system when walking it could not use power when going downhill maybe
it's not a robot, it's a mecanical sistem.
@Mhax94
I don't think apple and facebook will be there...
perpetual motion?
but like. wheels right?
I Want My Free Lunch and always knew that third leg would come in handy.
@archon808 If it was in constant decline it would be running down a slope, trading potential energy for forward momentum. This is appearently not the case as it walks on horisontal surfaces. It does not break the first law of thermodynamics, I'm sorry.
I would like to see it walk on some stationary ground. Without the floor moving beneath it, i doubt it can keep a steady pace.
un robot de energia infinita? mis respetos
@TopGunOriginal How would this help people walk?
I see the potential for AT-ATs!
"Walking down a slope"? It looks more like the treadmill is tilted upwards..
I tried to make this in very small scale :)
When I saw the title, I was thinking of Japanese.
this is the most advanced slinky, in the world.
Does it even count as a robot without all the tech in it?
I want to hire u
It's great, if your going downhill.

well skynet doesn't need wires..
but how fast can it walk?
предлагаю японцам разработать концепт новой русской деревни ,а то совсем уже жопа
yes a wheel does the same thing but a wheel wont help someone walk now step off and make something better if your going to criticize
Challenge: Make it run with kinetic energy.
@titaniumdioxides
Thank you, Sideshow Mel.
I think you are misunderstanding the implications of this and the physics that are behind it....
i want one of these as my pet.
@Butt4cak3 i recently view a video called quantum superconductors which they levitate an object. there's no friction.
Oh my god it's literally TARS from Interstellar.
I am from the future, and this is the start of skynet. we must band together as humans and destroy the machines
starting with this perpetual walking robot
15 km from one push? They gotto be using the sickest bearings!
