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.
based

I need to pirate some journal too

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
2:47 The tiny frog jumping and missing dragon fly while it slightly moves out the way had me dying 😂😂😂😂
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'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.
That clip at 2:40 is actually an incredible insight into how fast this thing- and things in general can really get
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.
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.
You forgot the seat haha
@@DemsW yeah.... 300G... *splosch* xD
@@DemsW yeah, I also kindly decline. Or do you want to deply the Boston Dynamics from 10:08 robots with that thing?
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
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?
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'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.
8:00 the idea of the small motor working over time to store energy reminds me of how the mantis shrimp punches so hard. It uses its muscles to slowly bring its hands in and then latches them and when the latch releases... POW!
yes thats missing in this video! the mantis shrimp punches INCREDIBLY hard.
Everything comes back to the mantis shrimp.
Oh yeah just like that
Mhm
Oh yeah ;)
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.
I love how intuitively designed it is! Simply amazing.
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
G😊sn
That's just amazing
Hi
Hi sir you are great
Great video
Great video
Thanks for the video
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.🔥
You really helped a lot in completing the levels. Nice work
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.
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...
@@AutPen38 But you dont see anyone asking why no one ever thought of it before. He didnt say a good idea is one that hasnt been thought of.
lol bruh imagine if like Arabs or Muslims got revenge against the racist jews/colonialists using this idea xDDD@@AutPen38
Dang it would be cool to see the scaled up version! They should start a Kickstarter for it haha

I would love to see them build one that is 10x larger.
Yeah I would like to see that landing...
it would be like 30kg,s and could easily be managed by a chute id imagine
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.
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

would love to see an efficiency comparison to other work multiplication mechanisms, like spinning up a rotating mass and abruptly stopping it to jump (or hit another robot in battle ;)). there you have friction losses etc, but in the rubber spring you have material fatigue/degradation etc
yeah, or a compressed gas. not as a propellant as that would be against the rules but as something that shoots out a linear actuator or something
1:03 Aww 😍 I’m glad you included this.
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
At 05:50 you can see a lab test usually made to study ductility on asphalts, basically for civil engineers to chose a good material composition for each particular road design. For more details read ASTM D113
You should do a video on the axiom of choice. The history is nice and the math and logic behind is super cool.
This man just hooked me up to tell me about jumps for 11 minutes.
And I feel like I enjoyed every second of it.
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 ?
this was EXTREMELY useful thank you man
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

What most people think genius is: “I could never think of that”
What genius actually is: “I am an idiot for not thinking of that sooner”
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!

New 'toy jumping robot' linked to over 120 blind kids
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.
That would make an interesting crossbow design :D Very cool jumper robot.

One small spring for a man. One giant jump for mankind. Fun video, Derek!
I don't know if there's a place to submit ideas, so I'll just throw this here. In college I took a course called The Physics of Music, and one interesting subject was why it took a few centuries to figure out how to tune a piano. It involves a lot of insight into the physics of sound and the vibrations of stretched strings. You could easily get a whole program out of it.
An interesting addition to this design would be to add one-way folding helicopter/drone rotor blades that deployed at the peak of the jump to extend the distance it could glide.
Or just wings that unfold with angled drag
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

A very very impressive robot that release an absolutly crazy amount of energy at once is Blip, a fighting robot that did great in BattleBots season 6. Its design uses a fabric/fiber being twisted by flywheel, constantly sped up by a motor to create a crazy contracting force when it's needed. It really packs a punch. 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.

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 can relate hog rider to this video
honestly the best soft tutorial ive ever seen. short and straight to the point ! i love it
Absolutely ingenious. This could completely replace wheels and rovers in land operations on other planets.
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 think saying this is not what i expected is an understatement
I love that you need to explain what is jumping
Why does putting a car in reverse make you nostalgic?
It takes you back.
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
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!
this is much better content than what i've seen before on Ve . new territory is free of cooled contraversion
Love your channel! What if you stacked two (or more) of the Carbon Fiber spheres on top of each other. Using the same middle string attached to the top motor, but now its connected to the bottom of the lower Carbon fiber sphere (as if you were squishing the number 8). Would this compound the overall energy being released?!
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.
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
If I could restart my entire career... I'd love to nerd out and work with these kids... I have so many ideas going through my head!
Yeah, stuff like this is why I am an aspiring mechanical engineer rn
@@TAKE_BACK_BRITAIN congraz. Good luck! This stuff is so fun... I got such a huge bug in my code right now I'm seriously contemplating a career change. Lol
Brilliant tutorial, thank you.
I need to see a 10x version of this jumping... will be epic!
always a good day when new veritasium videos comes out
Fr fr
9:38 that's nearly a 6-inch vertical leap.. impressive!
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
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.
your production quality has become amazing !! It shows how much you care about everything you post
There are more important issues to concern about instead of some stoopid jumping robot. How about finding a solution for global warming maybe ???
@@MrUssy101 but i don't think this undermines these kinds of accomplishments cause such mechanical solutions are very useful for space applications which helps us record the very data through which we study and learn more about global warming and how to tackle it- so it is helping solve global warming indirectly :)
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
I can’t wait to see an upscale one 😮
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.
You could say that this robot overtook everything else by... leaps and bounds
when i was a kid, i was a big fan of this kind of experiences ! ahaha thanks for your video :)
how at 3:00 you made a 3d model of jumper and modeled the moon! amazing grapics work 🔥🧨
This is a great leap forward in science.
That’s a stretch
A world record leap even
This could literally launch itself out of the gravity well of smaller solar system bodies, such as asteroids, or comets. Another useful application for mechanical launching could be lunar bases. Without an atmosphere, escaping rocket exhaust can accelerate dust close to escape velocity. This could have a sandblasting effect of structures great distances away from the launch point. If a vehicle could jump a significant height, before igniting traditional rocket engines, this could be reduced.
A great point! I was also thinking of this usage for pre-launch staging! If you're launching a rocket, you probably don't need/want the spring to be part of the launch vehicle. It's a little silly, but why not use a spring to start a rail gun launch? Rocket-powered dust would be very scary on an asteroid or even a moon. I never thought of that!
If possible, it sounds like a great idea for getting off the moon.
Great idea as long as no living organism is on board. Remember he said it produces 300g's! If you like your brain in your toes sure, but otherwise nah
@@Jacob-ft3oz well on the moon it wouldn’t be 300gs. When the Apollo astronauts lifted off the moon, they experienced around .33gs, they later said it felt like riding in an elevator. When astronauts lift off from earth they experience 3gs. Trained pilots can handle about about 9gs of sustained, positive upward acceleration, so on the moon the acceleration of this craft would still be deadly. On a smaller moon or asteroid with about 1/3-1/4 of the gravity of the moon, however, such acceleration would be tolerable.
Edit: sorry, this is wrong. The 0.33gs felt by the astronauts was during descent, not liftoff, where the g force would of course just be the acceleration of the spacecraft, with nothing to do with the gravity of the moon. It requires less velocity to escape the moon’s gravity well, so in that sense astronauts would be exposed to fewer Gs, but that is the only effect of the moon’s gravity on liftoff.
@@AvanaVana No, it's still 300g. Local gravity doesn't change the strength of the jump, the acceleration is the same.
Great video, and thanks! BTW, may I know how the team measured the maximum height reached? Is there an instrument that measures it? Thx
Spider knowing basic things like direction, force, elasticity… fascinating
