So, to be clear, if I jump right as I fart, that wouldn't technically class as a jump. I would be "taking off" as it were. Fascinating...
u get me
OPM 168
yep that was definetly the main point of this video
Wouln't your mass decrease, thus not counting as a jump?
and if you mini fart 2/3 times before an actual burst of true fart you can jump higher?
Jokes on you because I pirated a scientific journal and already know about it.

I love engineering like this- simple structures deployed in novel ways, designed rigorously and exploiting particular materials to achieve a breakthrough result.
Despite all the "Nope, impossible, cant be done" spammers.
These people should be designing software interfaces. Because man, that field is packed with hacks.
I imagine the spring y part stays on the ground and are 100feet tall ish with a payload for space or meet up with a few blimps at 50,000-70,000 feet land and then do it again to reach space

That's just amazing
Hi
Hi sir you are great
Great video
Great video
Thanks for the video
I love how simple this robot is and yet this exact combination of mechanisms is groundbreaking.
Simple is beautiful
Can you buy it?
Is it available to buy
it certanly isn't groundbreaking. The basic principle has been in use for thousands of years in catapults. It's groundbreaking in the sense that it doesn't go to the common place when we think about "robots", it's a barely eletrocnic catapult
@@20teverify lol, this is correct, the only groundbreaking aspect here is the incessant miss-use of the word 'robot'.
I would love to see this combined with that company creating glider drones to deliver to hospitals. They use a giant slingshot currently to get in the air, but that means they can only launch from a dedicated setup spot
Yes, It's like an arrow that carries its own bow.
That clip at 2:40 is actually an incredible insight into how fast this thing- and things in general can really get
Have they looked at efficiency loss from jumping on a compressible surface, like loose sand? I would think that would be a limiting factor in an environment like the moon, where there is a large quantity of fine particles on the surface.
Efficiency loss wouldn't be much I guess
Lunar ground is pretty solid overrall isn't it?
11:40 maybe ? Not all of the moon is made of regolith(the granules are a bit bigger than sand ) ,i think the seas are made of mafic rock which is incompressible
I was thinking of this the other way around, what if it lands on a soft spot and digs itselfs in/lands under a rock or something like this. Would it be able to get itself unstuck?
@@dkaloger5720 what about cheese?
When I made a water bottle rocket recently, I was surprised that they advised that a weight be added to the top of the rocket. It certainly made a positive difference. So I'm interested to see the same principle at work here.
Yeah rockets are weird in that you need to add weight to the nose otherwise they are unstable. IIRC it's because the center of mass is the center or rotation and by moving it higher it creates a higher moment of inertia and the air resistance can actually stabilize the rocket. Similar to how it's a lot easier to balance a pole with weight on the end then without since it takes more time to rotate and you have more time to correct.
They do, all the motors and electronics are located at the top.
The idea is simple, if your center of mass is in front of your center of lift, your rocket will flip around, that's why a dart has most of its mass at the front, and all its wings at the rear.
It's something you learn when playing kerbal space program, if your rear is too heavy your rocket will flip at the slightest push of air.
for a rocket the center of gravity (which is the point the rocket rotates about) has to be in front of the center of area (which is the central point that the wind pushes) in order to be stable.
ok

Would love to see a 10 times bigger one, that thing sound like it could send stuff in orbit! O_O
I love the slow build up and then "VOOM" its gone.
WEIRD! I had the EXACT same thought when I first watched this video... 4 days ago! I agree and would love see this put into practical application. Of course it could only be used for unmanned things such as satellites due to the extreme G's it would most likely produce at that scale. You'd also have to consider the possible effect it may have on the Earth's actual orbit considering that it's surface is exclusively what would be propelling it (as opposed to rocket fuel). I think this idea is a GREAT one! THINK of all the possibilities! Eco-Friendly as well!
@@dwirtz0116 it couldnt jump high enough
Making it larger doesn’t make it jump higher I believe
@@fergusfisher1315 So maybe some sort of 2-stage launch involving rocket propulsion in the second stage perhaps?
@@fergusfisher1315 watch at 11:00, it would go higher
This is very similar to the "flywheel bots" in Battle Bots. By spinning up the flywheel over time, they store a crap load of energy and release it all at once on its victims. That's why they always did so well.
I've taken suspension springs out of cars and every time I would treat it as if it was a loaded gun. The full scale version of this jumper is absolutely terrifying. I wouldn't want to be anywhere near that thing when it was fully compressed.
Imagine terminator but with an army of robots such as these the size of a person
Aren't you near four compressed suspension springs whenever you're driving a car?
Check out mooring line accidents
Had similar thoughts about the upscaled jumper. It would be a decapitation machine.
@@TAllenYT The key is that they are trapped while driving. When removing them for repair work, a lot of cars require that the springs be removed under tension. That typically means a careful extraction as if whatever holding the springs in tension slips or fails, the spring instantly releases the bound energy which can cause quite a bit of danger.
I'm not sure why, but such a small and simple thing made this one of my more favorite videos of yours. Especially once you pointed out how invaluable this would be on other planets with little to no atmosphere. I wonder if something like this could also implement a passive propeller that would slow its decent 🤔
It wouldn't be difficult to add something like retractable propellers, deploying automatically during descent, which potentially could allow the robot to start winding the spring even before it lands, thus reducing time between hops
im not sure propeller would work bc there would be almost zero mass on the planets
I wonder, could the jumping robot be so strong to the point where it shoots off and leaves the planet/ moon ? 🧐
Propeller and parachute would both be useless in 0 atmosphere. On someplace like mars where an atmosphere is thinner they would be work but very ineffective. Someplace like Venus where the atmosphere is thick the propeller would have greater efficiency than the jumping because of increased aero resistance
@@prapanthebachelorette6803 It would need to jump a lot further. The current estimate is that it can jump 500 meters, and it would need to be able to jump a total of almost 11 million meters. This could be optimized by changing the trajectory angle to maximize the distance, and the distance increases exponentially based on a slight increase of the initial force. 500 m vs 11M m may seem like a big leap, but it isn't as big as someone may initially think it is.

Hey Derek. Amazing video! I have one suggestion regarding this video. During the part where you were talking about sand fleas, try adding an image or slow mo of a sand flea, so that when I see the drawing about its muscle next, I can relate it to the image or video of it jumping. I didn't know what sand fleas looked liked and hence I couldn't understand this part.
If we got enough likes together would Derek commission the 10x larger version? Deployable glide surfaces + parachute + camera package is my vote for the payload.

Well the reason it only exists as a rendered model is it will take years of materials science work to solve. The amount carbon fiber can flex or rubber can stretch doesn't scale the same way mass does in a mathematical model.
Part of the reason the prototype works has a lot to do with 'the physics of the small' vs 'the physics of the large'
@@chrisblake4198 I wonder if the size of the prototype they built is optimized for the material strength they are using
You know its a good idea when you look at it and ask yourself, "how has this not been invented before?"
The NBA should allow the athletes to have nuclear missiles in their shoes so they can dunk from greater heights. It's a great idea because no one has thought of it before.
i work with patents, you'd be surprised how often we see things that would at first glance seem 'obvious'
Yes, it was. Five cent metallic jumpers with a screw or push button middle top when I was 3-5 years of age. Would jump like almost a meter, same [seems later were used in a self closing ash tray mech in bars and not sold as toys anymore. That was in the past century...

That is an incredibly detailed video into jumping and I love it. It would be amazing to see jumpers on the moon or mars as that is a highly efficient method of travel.🔥
I love how intuitively designed it is! Simply amazing.
Such a simple mechanism yet it broke the highest jump record.. Scientific discoveries and corresponding engineered devices are truly amazing aspects of human exploration .. like two sides of the same coin..
It's not that simple. I'd argue that the first space rockets are simpler for people to understand

Wouldn’t work if you do the maths
@@horatiotodd8723 I thought they said that it did work and would be a good idea because of inertia?
@@horatiotodd8723 So, whats the math showing it wont work? If everything is scaled up 10x, shouldn't it still work? That means using proportionally stronger bands. Proportionally stronger battens. Just 10x.
The old British sci fi shows UFO and Captain Scarlet both feature "Moon Hoppers" as a form of lunar transport. I remember thinking it was absurd at the time, but maybe they weren't so crazy.
Well only if you include fictional technology that enables you to survive the acceleration, in which case there should be way easier methods of transportation
....k?
Lol they were
Naa, humans won't evolve to endure 30 Gs anytime soon.
@@oyuyuy To make the jump endurable, you would have to reduce the Gs. You can, to some extent, if there is some axial space in the craft.
Human body would receive more damage enduring 30 g for 1 second than 15 g for 2 seconds, even less 10 g for 3 seconds (any astronaut can).
And the three situations would produce the same overall acceleration.
All you have to do is to smooth it up, for example plunging the passenger into a non newtonian fluid gel.
Dang it would be cool to see the scaled up version! They should start a Kickstarter for it haha
My gut reaction was to resist that was the optimal spring rate profile. My instinctive thought was to have a lower starting force ramping up as the speed increases....similarly to rowing a boat, to where you have a graphically smooth acceleration instead of a graphically smooth speed. After more thinking though, the larger impulse is definitely the desired effect unless you get some weird vibrations or harmonics. I'd be interested to see that with a high speed camera!
step 1: make huge jumper
step 2: stack smaller jumper on top
step 3: repeat until size is sufficiently small
step 4: launch them successively
step 5: achieve orbit
I think you have just rediscovered the rocket
@@fostena yeah but stupider looking
At 2:24 the initial speed shown is 30m/s, while orbital speed is like 8000m/s, or 250x larger, so I'm not quite confident that this can be done
better idea- make a huge jumper and stack multiple huge jumpers on top until you can climb and escape the atmosphere
@@fostena he rediscovered the rocket equation
I'd appreciate a graph showing additional weight at the top vs height of jump. Obviously at some point the additional weight will make jumps decrease height but at what inflection point and how quickly does height fall off past that point.
The relationship is between the mass of the spring and the mass of the head. A "perfect" collision will have both of equal mass. Imagine 2 billiard balls of equal mass vs different masses.
@@kevinliang9502 Almost as if we'd be looking at impedance matching in electronics then...?
Yeah.....NO. You must remember: Top- weight is a steering-mechanism. Of course, this applies only to NASA's balloons which are weighted ON THE TOP as thrust propels. Basic laws do not apply.
@@kevinliang9502 the jump is not an elastic collision between the spring and the body, so mechanical impedance would not apply here. It is rather an elastic collision with the Earth.
Increasing the head mass is beneficial because of the mechanical advantage: the spring works as a lever, and the head is attached to the farthest point of it. It is more beneficial to accelerate the farthest mass up than waste the energy accelerating spring masses inwards and canceling each other.
@@onebronx so what would be the conclusion here ? As light springs as posible and as high of a (head-)mass ? This seems counter intuitiv shouldnt the mass at some point effect the mechanism negatively ?

On a chemical level, natural musculature works similarly to the Jumper's motor slowly storing energy in the spring. The fibers are loaded with ATP and then the energy can be quickly released mechanically. Muscles are unidirectional chemical springs. Muscles are biochemical springs that fire asymmetrically.
If this were used in space though, the elastic would almost instantly dry out in the cold temperatures and so this wouldn’t work unless you insulated the contraption which would significantly reduce the power of this. It would also cause much resistance in acceleration.
Yes, but I think that it would eliminate the use of dead mass being used

The team has a video about the engineering of making it.
Link?
We designed a similar scheme which was only partially constructed before the team folded. Ours used latex rubber bands connected to steel cable to act on an axe. It was frightening! Some of the innovation was related to how the bands were manufactured and how to deal with the reaction. We chose a gas clutch to release the load but a geometric lock would've been better. Still regret not getting it mobile.

Hello 👋
This was fascinating. Awesome stuff!
That would make an interesting crossbow design :D Very cool jumper robot.
according to 0:43, if you jump while having an explosive diarrhea, you are technically classified as a liquid fuel rocket.
💀💀💀
Wonder how it jumps from sand, and how the compression characteristics of moondust would change the launch characteristics … perhaps a collapsible foot at the base would overcome soft ground without adding too much drag?
well if it's on a lunar surface, no drag, just a little bit extra weight to vehicle
ok
Yes....The first jump would be unaffected,providing you don't push it into the loose lunar regolith.Jumping out of a deep crater might be more difficult. Weight is critical so a small bladder of compressed air may impact its performance. I would love to see it scaled up and tested on the Moon.
Hhhh where do you even come up with these questions? Y'all are smart, gotta respect that
Then just add some damping in the calculation

7:30 The same concept applies to bows. As you increase arrow weight, the bow can transfer more energy to the arrow. In most cases it is minimal and the trade off of losing velocity is not worth it, given your arrow weighs enough to absorb the bulk of the energy already.
I am curious if they could damage their robot with the lack of weight. A compound bow can come apart from the lack of weight to impart energy to.
Just to clarify, I am using weight and mass interchangeably 😂
I was thinking this while watching. A modern day compound bow uses the same thing where the force profile is flattened by using pulleys so it is not just the linear exponential force profile of the bow limbs. Due to how similar the concept is and compound bows having been around a while now, I was surprised it wasn't mentioned.
And the work multiplication could be compared to a wind up crossbow, you store more energy than you could release in one go (with a bow) and release it with a trigger. I think it would be a relevant example for the video
Same as guns. If you dry fire, there is no primer of the bullet for firing pin / striker to hit and transfer energy to, so something will be broken. For modern firearms it will be either firing pin block or firing pin spring that will break after repeatedly do so for some 10k cycle. For rimfire or old pistol it may breaks the firing pin itself.
So time also equals power... Oh i get it... It's just like "SPECIAL BEAM CANNON"...
I found this concept fascinating and can't wait for the toy version to be available

It's funny that people have been making this type of spring in Polybridge for years now. The so called "Diamond Spring", but it was almost always used for compressing something very fast. Rotated 90 degrees, and suddenly it's used for expanding something very fast.
I was wondering where I remember exactly the same design from! It is obviously lacking the "elastic carbon fiber arms" part, but exactly matches one of their earlier prototypes with the hinges.
this is much better content than what i've seen before on Ve . new territory is free of cooled contraversion
Absolutely ingenious. This could completely replace wheels and rovers in land operations on other planets.
One small spring for a man. One giant jump for mankind. Fun video, Derek!
This is a great leap forward in science.
That’s a stretch
A world record leap even
scaling it up 100 times would be super cool and probably would go viral so it would be worth it
I love that you need to explain what is jumping
Very interesting. I kept waiting for the landing, reposition and launch again demonstrated. At some point the battery goes dead so how many jumps can it make?
Yeah, I was also wondering if the steel weight can be replaced by a battery or some other 'sensors' or cameras..?
It may be able to recharge the battery to some degree by harvesting energy from the impact
I wonder if adding a Small strong magnet in the center inside of each carbon fiber spring would increase the efficiency. This may possibly be achieved by not allowing the spring to rebound outward after its full release inward. By allowing the magnets to lock together after ignition might hold things more streamline on release. I noticed some wobble in the slow mo as the springs rebound. Stabilizing that energy may help thrust upward you could always add or subtract weight in the nose to balance the addition of the magnets added weight. Just a thought I may be way off… Very unique science here either way. Great video.
Thats a cool idea, could put a velcro equivalent or something sticky to keep them together maybe
Recharging would be more energy consuming
You may be right it would be something to try. But on the otherhand, have ou ever seen an arrow in flight in slow motion? Its not at all like the expression "flew straight as an arrow". It actually moves through the air like a snake or like an eel in water!
Its like a natural gyroscope of sorts due to harmonics is my understanding. Perhaps that wobble is part of what makes it what it is, like the arrow?
Only removing the wobble will tell.
I wish i could do that experiment, it would be fun to see the result!
sound interesting but it would be difficult since magnets are very brittle and would probably smash into each other and break.
It wont and you can tell by the way it is.
Big ups to the builders of that jumping robot.
Jumping shoes coming soon. Combine these with the new vest that turns into an airbag. Would also increase the take off rate of a jet pack
I worked in the injection moulding industry as a technician and have operated machines with clamp forces and speeds far beyond what the pump and motor would normally be capable of. They relied on an accumulator, basically a pressure vessel that was ‘charged’ by the pump and motor in the idle time between cycles. Imagine if robots employed this principle… 🤔
A robot that walks using pneumatics as the source of energy for moving its limbs... It would have a tank for storing pressure, a compressor and valves directing air to the tank or straight to the limbs. During normal movement and when standing still, air pressure not needed for movement would be directed into the tank but when it needs to, it could release a bunch of pressure from the tank to, for example, jump. Or the pneumatic system could be used only for boosting the movements otherwise accomplished with electric motors when the robot needs to do more than just walk normally.
@@Kepe That’s exactly what I’m talking about. Except that nitrogen would be used rather than air. An accumulator would contain a nitrogen filled bag which can be compressed much more than air. Hydraulic fluid would be pumped into the accumulator which would compress the nitrogen filled bag allowing for much higher stored energy than with air. This is how the accumulators in an injection moulding machine work.
@@welshsteve2009 i think well pumps do something similar, but i think the compressed gas acts as more of a buffer to keep the pump from cycling constantly.
You'd need a very low friction fluid. It could work. But the simplicity of springs lends very well to scaling production.
@@SaintSaint The machines I ran pumped hydraulic fluid. The nitrogen in the accumulators can compress more efficiently than a spring and produce a more desirable force curve.
I think saying this is not what i expected is an understatement
"I did my PHD studying how much people learn from videos. Unfortunately it is shockingly little"
-Guy who makes mind blowing educational videos for a living
such a really well designed robot!
I love this kind of stuff. These designs and discoveries that seem so miniscule and irrelevant are always my favourite thing. We all thought we knew springs, but here they are designing a new spring. I cannot wait to see how these change the future products
I'd love to see this type of robot device installed into the knees of one of those humanoid robots featured in the clips of this video. With programming, the more the motors would turn the springs thus compressing, you could alter the robots stance, lower and upper body position to compensate the energy exertion. Then boom, you have a leaping humanoid robot
They already have robots that can do flips. Boston dynamics has some, and has had them for years now. So this isnt that impressive. I would be more impressed if they taught robots how to use jet propulsion technology, so they can hover like a harrier jet
@@3rdreichball525 flips are one thing, but this isn't flipping. This could be a robot jumping vertically or leaping forward a good distance
this sort of thing also seems like it's probably going to be way, way better at returning energy for every single step, than electric motors would be able to. With that, you've really solved a good portion of battery power issues with those sorts of robots.
I was thinking about it, and it could be made in such a way that under normal operation, the spring is basically disconnected, but then when they want the extra jump power, it can lock and the motors would then compress the spring as it gets into jumping position and releases it.
I imagine that the timescale requirements of these humanoid robots doesn't allow for a long winding up periods - they have to perform rapid movements and it is not known what direction those movements are gonna be. Those robots are sensing the environment and depending on outside factors they decide how they will move.
trying to imagine the forces on something so light it was hard to decide how much effort had to go against air resistance vs the constant pull of gravity and it made me wonder how dangerous it would be if someone got in its way at the start. i didn't think it'd be very lethal coming down if terminal velocity was reached soon after it began its descent though. i think the problem with a moon hopper would be launching off a soft dusty surface. a large version for passengers would be funny since it'd kill everyone in it :-)
Adding some little fins to help it spin would keep it stable. Might give longer flight
One of the best videos in a while. The sand flea locking mechanism is just fascinating
Looking forward to the full scale one, I hope they're doing one!
1:03 The way that cat goes from a cute fury little critter to a vicious predator is amazing.
9:38 that's nearly a 6-inch vertical leap.. impressive!
Just wanted to express how helpful your videos are!! you are extrely good at explaining tNice tutorialngs in-depth but still at a basic level for
It is tempting to think that a 300 gee force would "kill basically any living creature," but that is far from true. A typical concussion due to linear acceleration happens if your head accelerates in the ballpark of 100 gees. And even 300 gees is survivable, though the concussion is likely to be severe. It's just that the acceleration is very brief, as it is with this jumper.
While a 300 gee jump would cause serious injury to a human, fleas experience peak accelerations over 800 gees when jumping, and woodpecker heads experience accelerations of over 1200 gees when pecking (on every single peck!). So it certainly won't kill everything.
Thanks for having some numbers.
I was going to say the smaller the creature the greater the survivable g force but that's an over simplification. Smaller creatures have proportionally narrower bones so they trade some of their g force survivability for less bone building.
@@andrewharrison8436 Well the animals I mentioned have special adaptations to survive those accelerations, so they will never compare directly to animals that don't. That said, it is definitely true on large scales that smaller organisms take acceleration better. The extreme case are bacteria. _E. coli_ and _P. denitrificans_ have been found to survive and even proliferate at >400,000 g.
Its just "G force"
idk where you're getting "gee" from but that's straight up wrong. As is most of what you said.
Going the opposite direction with this design, I wonder how long a very efficient spring could deliver energy at a measured rate? Could it be a form of mechanical energy storage and delivery?
Ever heard of mechanical watches? Some could keep running for ~10 days or more..
@@supergps2000 Except the amount of energy stored in the winding spring of a mechanical watch is miniscule. I was thinking like a battery, and storing enough energy to power a car or bike or something.
The issue is that springs are under stress when they are compressed, so it would be either dangerous (imagine a battery exploding) or would deform the string over time. There's a reason why you should NEVER leave a bow strung, and why you should always check strung instrument before playing. The first one may snap, the second one is constantly deforming.
@@swbusby That's exactly why springs aren't great for storing large amounts of energy. Compared to the alternatives, their energy density is abysmal, they're heavy, and they're dangerous. Other mechanical energy storage systems, like flywheels and pneumatic pressure, have the same problems to various degrees. They have useful applications, but they almost always are moving something else. They quickly become inefficient when they have to store enough energy to move themselves, too.
That's a thing. They even used to make buses that were powered that way.
Brilliant tutorial, thank you.
i can see this being used to give portable missiles momentum , would make some awesome infantry weapons systems, imagine launching a pod 1/2 km up w no smoke signature then just guiding itself down to target
always a good day when new veritasium videos comes out

I could imagine some sort of stored energy being used with a running robot. It would have to - store, release, store, release - with every running stride. To build such a reliable and consistent device would be a hug engineering challenge, though.
So time also equals power... Oh i get it... It's just like "SPECIAL BEAM CANNON"...
Some robots already does this with compliance, e.g. cassie/digit from agility robotics
@@benjackson6260 Literally what a killer usb does. A bunch of small capacitors.
Your PC's usb slots aren't putting out much energy at all. (5 volts at cirka 2 amps). But if you let a pc killer stay plugged in for long enough, you'll maximize the capacitors and trigger a sudden jolt of power at about 215 volts straight into the pc.
Low power over a long period of time = maximum power ejected at milliseconds.
@@LinusAkaPano yep... Actually have tried this on my principal when I was in school... Blew his pc up... Unfortunately he wasn't using it at the time... Otherwise would have been full payback... 😆😆😂
It takes time for each store, so step rate would be slow
Instead of using a string on a spool, if you used a pin there would be less friction (but maybe a little more inertial resistance) possibly allowing the spring to engage faster
