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...

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?

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

David Dickey 年前

You know its a good idea when you look at it and ask yourself, "how has this not been invented before?"

AutPen38 年前

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.

Synoptic 4 7 ヶ月前

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...

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.

Micah Kress 8 ヶ月前

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.

Aki Beats 4 ヶ月前

That clip at 2:40 is actually an incredible insight into how fast this thing- and things in general can really get

Portal FPV 年前

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 🤔

Wojciech Bieniek 年前

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

No one 年前

im not sure propeller would work bc there would be almost zero mass on the planets

Prapan The Bachelorette 年前

I wonder, could the jumping robot be so strong to the point where it shoots off and leaves the planet/ moon ? 🧐

Gabe C 年前

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

Haakon Sjogren 年前

@Prapan The Bachelorette 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.

Metrion77 4 ヶ月前

It would be interesting to see how it would deal with terrain that can absorb that impact drive, like deep snow or uncompacted soil. You can only exert as much force as the ground holding you, after all.

Freedom Phoenix Goat 年前

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.

captainexiled 年前

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!

Henry 年前

@captainexiled it couldnt jump high enough

Fergus Fisher 年前

Making it larger doesn’t make it jump higher I believe

captainexiled 年前

@Fergus Fisher So maybe some sort of 2-stage launch involving rocket propulsion in the second stage perhaps?

Matthew Douglas 年前

@Fergus Fisher watch at 11:00, it would go higher

Abha Vishwakarma 年前

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.

Ptao Tom 年前

9:38 that's nearly a 6-inch vertical leap.. impressive!

Mysda 年前

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.

Jordan Champ 年前

Link?

metimmee 年前

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.

Simple is beautiful

Emil Pelaa 年前

Can you buy it?

Emil Pelaa 年前

Is it available to buy

Felipe Bertolini 年前

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

Simon A 年前

@Felipe Bertolini lol, this is correct, the only groundbreaking aspect here is the incessant miss-use of the word 'robot'.

Jdbye 年前

I feel like this principle could be applied to competitive robot battles very effectively. The drawback being it'd take a long time to recharge the weapon if it missed, but if it hit, it would be devastating.

Bilal Gavacs 年前

Nah the Robot is called the swarm, itd be round with like 8 of these around it. Then they just repeatedly jump into the other robot with barbed pikes attached the the end. If not destroyed its knocked over or slowed down enough by the jumper robots. The main machine then comes with a big hammer and just rapid fire swings on it. Worst case scenario, the pikes stick in, recharges then starts launching the other robot all over the place until it breaks

Bozey0 年前

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

3rd Reich Ball 年前

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

Bozey0 年前

@3rd Reich Ball flips are one thing, but this isn't flipping. This could be a robot jumping vertically or leaping forward a good distance

daltotron 年前

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.

Kas b 年前

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.

Psyese 11 ヶ月前

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.

Chris From SouthAus 年前

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.

Saint Saint 年前

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!

River Reeves 年前

If possible, it sounds like a great idea for getting off the moon.

Jacob 年前

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

Avana Vana 年前

@Jacob 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.

Francesco Pezzoni 年前

@Avana Vana No, it's still 300g. Local gravity doesn't change the strength of the jump, the acceleration is the same.

Isaiah Condreay ヶ月前

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!

noseudian x. 年前

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

jama211 7 ヶ月前

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

Jon Harris 年前

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.

Kotresh G 年前

Efficiency loss wouldn't be much I guess

Zeno 年前

Lunar ground is pretty solid overrall isn't it?

Dkaloger 年前

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

Mark M 年前

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?

djturnz 年前

@Dkaloger what about cheese?

Mator 年前

This reminds me of something I did back in high school. I'd take a rubber band and wrap it around a ballpoint pen, then pull the rubber band taught and allow the pen to slip out, shooting upwards as the rubber band released its stored energy. I didn't ever exactly measure how high it went, but I think it was launched at least 10 meters. Very entertaining.

Shadow Master 7 ヶ月前

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.

HRIDYANSH bhardwaj 3 ヶ月前

Yes, but I think that it would eliminate the use of dead mass being used

m m 7 ヶ月前

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 :-)

M.I.L. (My Interesting Life) 年前

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.

Tyler C 年前

Thats a cool idea, could put a velcro equivalent or something sticky to keep them together maybe

Telmuun Davaadalai 年前

Recharging would be more energy consuming

patrick farley 年前

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.

@Horatio Todd I thought they said that it did work and would be a good idea because of inertia?

Sailing SV Zara 年前

@Horatio Todd 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.

Dang it would be cool to see the scaled up version! They should start a Kickstarter for it haha

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?!

YAHUsha 年前

Jesus Christ died for our sins, rose from the dead, and gives salvation to everyone who has faith in him. True faith in Jesus will have you bear good fruit and *drastically* change for the better! Those led by the Holy Spirit do not abide in wickedness. God is three in one; the Father, the Son, and the Holy Spirit! Bless him! As I am led by the Holy Spirit, nothing I state is a lie, but the truth of God. Anyone who tells you differently is misinformed or a liar. They do not know God, nor led by him. Anyone who *claims* to be a Christian and is against what I am doing, for any reason; the Holy Spirit does not dwell within them. They know not God, read his word, and their religion is in vain. Do not hear them, they will mislead you, the lost cannot guide the lost.

YAHUsha 年前

When you trust in God and cast your cares (worries, anxiety, depression, suicidal thoughts) upon him, they will be NO MORE! Know that there is power in the name Jesus Christ! His name casts out demons and heals! The world is wicked, evil, and of the devil. I too, was a wicked sinner of the world before I opened my heart to God. I am living proof of God's work and fruitfulness! He is an active God who hears the prayers of his! God's children are set apart (holy) and righteous. The devil is a liar that comes to steal, to kill, and to destroy; that includes your relationship with God.

Chris Blake 年前

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'

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.

Aren't you near four compressed suspension springs whenever you're driving a car?

TheMrarrie18 年前

Check out mooring line accidents

Saccaed 年前

Had similar thoughts about the upscaled jumper. It would be a decapitation machine.

Saccaed 年前

@T. Allen 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.

Travis Woolston 年前

Sounds like we've developed ways for robots to jumper higher than us as well. amazing.

Dominique 年前

Would be possible to build it bigger like the size of a truck for example and still maintain this amazing size versus distance ratio? Could it carry something heavy in its capsule? If so, could this big version be released from an airplane mid air and reach even higher?

exwhyz33 7 ヶ月前

The next step is to have 'stacked or cascade' multiple springs so as the robot reaches its peak height, a second spring unleashes more energy to lift the robot further.

Science Geek Grandpa 年前

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.

Casey Murray 年前

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.

deadall127 年前

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.

dave BingConsultingGroup 年前

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.

I have never taken the time to thank you and your team about posting videos in spanish, I really appreciate the fact you are doing this, since here in my country no public education entity has ever taken the time to teach us as your chanel does. I know this is a no big recognition and makes no justice enough of your work and your prestigious person, but I just happen to notice that no other science youtuber from a 1st world country has taken the effort, time or resources, to get their content being translated expecting nothing in exchange. I feel really exited about the things I learn in everyone of your videos, I wish I have had a better science foundation to understand in full about the whole content of the topics but, as you might probably certainly assumed science education is really neglected in third world countries, now that Im a grown up person I realize how important science education is, and I will definitely encourage my kids to learn about it and with the help of your videos that will going to be easier for them (at least until they learn english since there are so much knowledge we still need to get but the majority is still available just in english), greetings.

Instead of adding a steel weight to the top, what would happen if you added a steel flywheel in its place? I imagine if the string was to transfer its energy to the flywheel on release, it would probably not go as high. However, maybe the motor that is pulling the string into tension might also double as a driver to start spinning up the flywheel/gyro before the string releases its full potential. Would that stored flywheel energy allow the vehicle to steadily climb even higher, or would it cost too much in energy transfer going to the 'legs'?

Question: What if you added more carbon fiber sides to this jumper. Instead of having four connectors with the rubber bands, what if you had 8 or 16 connectors with more rubber bands so it could store more kinetic energy right? I know that it would add weight but its counter balance of force would outdo the extra weight no? I am probably wrong but I am wondering if anyone can explain.

If this could scale to bigger size machines, it would be very helpful.

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.

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

Naa, humans won't evolve to endure 30 Gs anytime soon.

ilmaio 年前

@Carl 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.

D W 年前

Has anyone tried putting the head weight on top of a fully compressible spring? Does that store any of the initial energy for release later?

Iain McClatchie 年前

The emphasis on work multiplication, which lets you minimize the size of the motor, is curious given that they then added inert mass to the vehicle to go higher. They could have instead made the motor bigger (and used less work multiplication). I think some explanation of why adding mass made it go higher is in order. There is bound to be some optimum amount of mass, and that's going to come because two opposing effects balance at that point.

TheKamiBunny 年前

The thing is, a larger motor might lead to a larger device in general as an electric motor takes up more volume/mass Also having a weighted payload also helps with future developments of the design with regards to measurement devices or other electronics that may be needed for navigation and potential weight can be replaced.

tobi321wwwto 年前

I think an Electromagnetic Jumper would also be nice. It does not violate any of the mentioned rules or? I have not calculated this but maybe its a promising idea to charge a very weight-efficient condensation to launch it from a Metal surface or even a Strong Magnet. If the Surface matters, it could carry the magnet.

AM D 年前

Organisms use latches and store energy over time at the molecular/microscopic level too. So in a way this is simply a better bio-inspired or biomimicking robot than the Boston Dynamics robots. Edit: Actually I'm having a hard time finding exact analogues to this in molecular systems; titin may be close but it's not exact; same for viral DNA capsid packing although that deserves further consideration; cnidocytes accumulate and store potential energy over time, but not as tension but via chemical concentration. So there might be something truly novel to this

Anony Moose 年前

If they added fins on the side of the robot, could they potentially make it go higher by adding a rotational force to stabilize the projectile. Kind of like how a tank shell works, or rifling in a gun. Could that be a way to potentially make the robot jump higher?

Master of None 7 ヶ月前

It would be cool to see if they could make a three-stage jumper kind of like a rocket. the mass payload of the initial jumper would be another jumper that would be smaller than would at the peak of the previous jumper jump of that jumper to go higher. It would then have a smaller jumper that would jump off of that one at it's peak.

Charles Goode 年前

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.

Kevin Liang 年前

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.

Attila Asztalos 年前

@Kevin Liang Almost as if we'd be looking at impedance matching in electronics then...?

Cloudlounger 年前

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.

onebronx 年前

@Kevin Liang 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.

Emco Tec 年前

@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 ?

How many times can the rubber bands cycle before they become fatigued? I feel like the carbon fiber would have a longer fatigue rate, but the rubber band seem sub-optimal for long missions.

I’m curious to find out how well the robot performs under prolonged exposure to extreme cold temperatures

Aidan Xavier 年前

It might work better. Here's a potential materials science driven argument in that direction: The fatigue life of many, if not most materials decreases at high temperature, meaning that materials fail quicker under repeated stress at high temperature. Lower temperatures then generally result in longer lifespans with that model. Fatigue is I think the most appropriate way to view this. Given that this is a spring, it presumably is designed such that none of the materials experience plastic deformation - where the material remains deformed - and instead only elastic deformation - where the material returns to its original shape. Factors such as ductility and impact resistance, which do perform worse at low temperatures, shouldn't apply here because the material structure is not reaching that level of deformation. In fact the yield strength, the limit where the material deforms plastically, decreases with temperature as well, and so in lower temperatures, the material could be more likely to remain within elastic deformation. This feels unintuitive, and I'm not fully convinced myself, but most materials do fatigue and degrade quicker at higher temperature, including CFRP and Latex rubber. A counterargument may be that the absorbed energy decreases at low temperatures, this is something that may be harder to generalize. It's worth noting that this jumper might also function better at lower temperatures, due to the increase in elastic modulus of many materials at lower temperatures, which could make it springier.

Another use of work multiplication in robotics which would be fascinating would be to release only part of the stored energy instead of all of it. Maybe doing 3 smaller jumps instead of a single large jump for example. The string might have to take the tension instead of the spring though!

How high would one 100x bigger go? Would it be 3100m plus the additional 19% efficiency? Because that would be nuts to see
