Jumping robot leaps to record heights

- Roboticists have designed all sorts of jumping robots over the years, and many of them have been inspired by biology. But, as diverse as the natural world is, evolution hasn’t cracked every option.
Now a team of researchers has investigated the differences between biological and mechanical jumpers - and have managed to design a device capable of leaping over 30 metres into the air. This is 3 times the current record for a jumping robot, and they did it with a technique unavailable to the biological world - work multiplication.

This is slightly incorrect, you forgot about the Issus aka planthopper. They’re the only animals known to possess a naturally occurring gear mechanism.
I'm glad someone else noticed, they have intermeshing leg notches that synchronize their legs when they jump, also pistol shrimp cock their claws back with a ratchet-like mechanism, lots of examples.
Also literally the grasshoppers the video described use a kind of spring mechanism
@@MrAlziepen yes and trap jaw ants have a similar mechanism for aligning their jaws as well.
Those geared mechanisms don't use gear ratios to multiply power though, they only synchronize the legs
I mean mantis shrimp have a naturally occurring single tooth ratcheting mechanism which is why the have the ability to punch so hard and with such force
Reminds me a bit of the great egg race. How far could you get a vehicle to go with just a rubber band to transport an egg. Some of the designs were very clever.
There was a variant for speed over a set distance. This is very similar
At University the contest was who could throw an egg the longest distance without it breaking. So, you had to design a 'crack' landing device (judged on weight( and throwing machine judged on distance. You had a maximum spend of $100, and you couldn't buy a completed off the shelf item.
The winner used a very dangerous looking home made slingshot.
I can't remember about the landing material
@@wakelamp Highest farthest fastest ...
sounds easy, low angle powerful slingshot to shoot a spherical holder so there isnt much energy transfer upon landing, just centrifugal force. Faster it spins the better. There, I win.
"what nature is not capable of"
just a second ago mentioned that crickets are actually very much capable of it...
Probably talking about the use of gears in order to get very large trade-offs between force and distance, allowing for creating more tension than would otherwise be possible?
Basically, nature almost never makes gears. (Though iirc there might be few cases of gear-ish things in nature?)
@@drdca8263 I think the topic is the following:
Similar to an animal, the robot can jump multiple times using an onboard motor. The motor has limited power output, but for a jump you need a lot of power released in a blink of an eye.
So the robot has a wind up mechanism and stores the energy using rubber bands, increasing the power output for a short time frame after release.
Crickets do something similar with their legs and muscles.
@@jojojo9240 sure, but crickets do this in a lever-y way, while this does it in a gear-using way, which allows doing it much more (without needing a very very long lever)
@@drdca8263 I might wanna look into how crickets do it more, do you know some source you can give me?
@@drdca8263 mantis shrimp is also crazy
Great ! But the intro about "it's not biology inspired" is a bit irrelevant. And you can actually find "load-release" mechanisms in biology (like "exploding seeds").
Probably the motor with the spinning axle is what he was referring to
@@diggoran That is also what Matthias was referring to. There are mechanisms that use muscles as motors to store up energy to be released, like the grasshopper with the elastic rods.
And that shrimp thing if i remember right, the one using gears
@@serbanandrei7532 mantis shrimp. Good call
@@CliffSherlock also the pistol shrimp and chameleon tongue
Maybe I should build this one?
modify it to eject projectiles, like arrows or something
Yes definitely
@@fitrianhidayat So, make a Bow?
Look at the bunch of formula. Behind this Bart Simpson's experiment, brain-rackng calculations stand!
Why doesn't TH-cam recommend me videos like this?
Mantis shrimp mechanism could be a good source of inspiration too .
"Breaking tech news: bullet vibrator grows legs, attacks migrating birds"
Imagine 2000 of these jumping through New York over buildings like a flock of migrating birds
Ok that's a cool image
The abysmal footage showing off the allegedly groundbreaking robot.
That would be a good design for a sort of wierd crossbow
It may not dance, but this is one of the coolest robots I've seen in a while. I'd like do put a little deployable parachute and camera on one.
Wow, that was really cool
Wow, that was really cool
That's pretty cool! I remember reading this similar concept in a sci-fi nova "Empire Builders" (Ben Bova)
(The book does not go into detail about the mechanisms or math behind it. Just an observation from a character's point of view of how a spacecraft went into space)
It's pretty neat to see these concepts taking shape/form in reality
im pretty sure Ben Dova wrote that book
Mathematicians: "This is the limit of what is theoretically possible with available materials..."
Me: "Just add more legs..."
Same problem NASA has. You add more energy (legs) but at the same time you add more mass that has to be accalerated. This jumper is close to the optimal mass energy ratio for best accelaration. To improve it you have to store more energy without adding more mass, what can only be done be new (jet unknown) materials.
Wow they didn't even manage to show a zoomed-out view to illustrate how high it jumps.
Read the paper
@@williamchamberlain2263 You want me to spend $32 to download a paper, and furthermore, you want me to believe that inside the paper there will be a zoomed out video of this robot jumping?
Why isn't that video... in this video? Why would it be in a paper?
@@diggoran you deserve a 3 story house for pointing that out
Literally at the beginning of the video?
About 30 meters, thank me later
While a rover actually using these principles would have nowhere near the height or range this little guy has (since it'll need things other than a motor and battery onboard), I'm sure even a fairly heavy lunar rover can jump a few yards with minimal weight dedicated to the ability.
You could probably build a refined version of this that can alter it's trajectory, take high quality pictures and minor sensor readings, and have the ability to charge itself, and you could release swarms of them with an unsophisticated AI coordination program that has to move away from other jumpers, to cover as much land as possible.
The nice thing about this design is aside from the control mechanisms, the winch that puts the legs in tension can be made in a bunch of different novel ways to where it would consume almost no power. I would say a set of microservos with filaments to slightly adjust the tension or release on some of the legs work give you a decent way to control direction. You could use all kind of weird rotation and release mechanisms like thermal actuators.
Looks like a spring loaded mechanism rather than a "robot"
An alien: Ahh, so these are small weird alien creature that Earthers send to the moon. Maybe we should send them dome stone-crabs as gift
and my brain immediately thought of a crossbow.
Muscles can also do work multiplication. Not through multiple strokes but the fiber orientation of pennate muscles acts as a biological gearing mechanism.
What if I can throw a frisbee higher than that?
Very interesting. I see a great future for this technology in the anti personnel mine field.
psychopath
@@parallellink it's only business, don't be mad.
2:22 if there is no atmosphere, a streamlined shape is not needed.
Maybe for Mars?
I think this video was more likely made by someone who has a very simplistic view of nature and its mechanisms. Next you'll be telling us that a hammer drives nails better than the Shark who shares its name.
There are indeed biological ratcheting mechanisms, and they're used in jumping
Not a robot
The military applications of this are endless
2:59 - "The next giant leap in space exploration..."
I see what you did there
That's not a jumping robot...that's a slingshot that has to be re-loaded.
This will be made smaller and into groups of them called "synthetic muscles" because in groups they will be awe-strikingly powerful. Androids with Terminator strength, here we come.
This is only 24 joules.
Let's say we use a carbon fiber leaf spring, it extends at 55 mph with 1700 pounds of strength. Use gears to covert that to 440 mph with 212.5 pounds of strength moving long bent legs to increase the contact time and reduce Gforce inefficiency.
I'd say that both breaks the record here and makes for good scalable murder muscles for a terminator.
It could punch through you like a bullet and change gears so that it can carry a car while using normal collections of motors to power slower precision movements.
Become rich and make this immediately.
The next giant leap to moon exploration will be.. a giant leap.
Does anyone explain how anything works anymore?
Missed the opportunity at the end...
Looks like a 50-50 chance at getting another corrective positioning jump all while having only jump power as the only means of directional control.
I'd say not even 50-50.
If it lands flat then it's on its side.
Then it reels in, toward a ball-shape (initially approx. 90deg out of alignment)....CoG takes over, looks to be heavy "on top" when in correct position. So the second time around it'll roll in the wrong direction and fail to align for #2.
@@gordonthomson7533 The clip at 2:10 seems to show it self correcting. I wonder how it would work on an uneven sandy/rocky surface, though.
Future spaceship launch tech
It looks like it could hold a gun whilst jumping up and down on the streets.
Where can I get one of these mechanical jumpers?
You don't need an atmosphere to fly.
So what makes it a robot? All you shown was a machine with nothing describing how it functions. Can it navigate? Can it make any decisions?
Thats literally just a bow that fires itself
I wonder could a smart child build a jumping robot from scratch? Because it seems simple enough to replicate, just a fancy windup toy excluding carbon fiber
Jumping boots? JUMPING BOOTS?! 😲
Useful for ISRO scouting! Like an infinitely reusable scout dart. I bet it could cover huge distances in a day and if it can be outfitted with light solar panels it could do awesome in swarms for mapping hostile environments
Great video!
Tesla New propulsion for their rockets, be like...
Engineers: how strong does it have to be?
Elon: yes
Engineers: but it is already on the limit of what's mathematically possible!
Elon: hold my "insert here his false promises projects"
In 3 weeks this will be a toy at the gas station for like 4.99.
i could see this in a school science fair or some rocket competition.
If this is a robot then my paper plane is also a robot
Really? I would wager that using a small explosive charge acting on a piston would propel an equally weighted object significantly higher than using rubber bands.
Build it, show me
For one, they're not using rubber band, they're using the extreme tension being built up in the material as it bends. Second, an explosive charge immediately stops delivering its maximum potential impact the instant there's no longer a seal in place, while this thing doesn't seem to leave the ground proper until it's almost fully extended. And third, making something like this durable enough to handle an explosive charge would likely mean it'd have to be significantly heavier.
Plus, at least in theory, this can launch itself multiple times in the right circumstances. Using an explosive charge would eliminate that potential benefit.
I guess this mode of transportation is slightly inconvenient for passengers.
The military wants to strap a landmine to this.
That's one of their main kinks.
Something of a leap to call this a robot.
@0:35 "Strong muscles" shows a Kangaroo.
Then we talk about springs a little...
@0:47 "But as diverse" shows Kangaroo again, ironically an animal with weak muscles and spring tendons which has now been shown twice. Not really strong or diverse.
Would a pneumatic piston design be able to do better than this?
That's not a robot, it is just a mechanical device...
Wow it jumped maybe 3 inches.
I'd like to see this in large scale
Jumpings one thing, but for it to be useful as a form of travel...on the moon or otherwise, someone's gonna have to sort out ... landing.
I am wondering the difference between energy needed to reboot / rewind the mechanism and the amount of energy it could produce if the jumping could be converted into energy. Force= Mass x Acceleration; then motion's magnitude, displacement, velocity and acceleration can be derived; P.E. = mgh = Energy --> work = force on object leading to motion; power = rate of work .. Kinetic Energy = 1/2 mass x velocity squared; it could be the basis for a new mechanically generating energy machine. Hip Hip Hurray Newton! A new turbine energy machine that could power the robot itself perpetually!? Kiumars Lalezarzadeh
A little step for mankind, a giant jump for robots 🤖
You butchered the quote, ma dude
Bet it can’t jump higher than my wife jumping to conclusions
A fairly obvious improvement would be to have the impact of landing do at least some of the work of recharging the spring, much as a pogo stick does.Also, adding some wings would allow it to travel much longer distances, at least in areas where there is an atmosphere.
Yes, but these improvements would make it heavier, so the maximum height would be a lot lower.
@@willempaternotte4071 I don’t think it would be that much heavier, as all you would need to recapture the impact would be a ratchet, and the wings could just be very lightweight foam.
@@macrumpton well, if the wings stuck out at all, then their gonna break or deform into uselessness on landing... but the ratchets a great idea.
@@BeauZoe I actually did some preliminary work on a device like this about a decade ago, and my idea was that the wings/fins would act to steer the device to come down at a good angle for “recharging “. The way this would happen is the fins/wings would move from the middle of the device (when flying) then move to the back of the device when diving for guidance like an arrow. On impact the fins would flip to the other end to stabilize/steer (like an arrow) the device in its upward trajectory. If you’re really curious, send me a message and I will send you a sketch.
@@macrumpton that's true, but even light foam could be considered heavy for such a light vehicle, you could use expensive materials like aerogel, but that's very brittle, i don't know if it'd survive the landing.
It would also be heavy, because you would want some kind of steering mechanism and they should probably be able to fold in and out, for a aerodynamic launch. This all would add weight. Although the folding in and out could just work like a parachute, the wings would catch a little air and lift themselves up, steering seems difficult to make aero and light.
That would be "extensible" joints not extended joints.
Is it a bird, or a plane? No it's RoboYeet.
Make a pogo stick like that
0:17 The dark side of the force is a Pathway to many abilities tha some consider to be... unnatural
Anger, fear, elastic bands ... these are the paths to the dark side.
pretty sure they will make lethal weapon out of it
Hey thats not true. Evolution did crack some. Octopus and related do have similar mechanisms.
It's gonna be used for landmines. Let's just get that out of the way.
Makes me think of John Carter and the Hulk
pyon sugoi!
can i strap them to my feet and become captain kangaroo tho
A nice look and see with no explanation. Some facts would have been appreciated.
Just peeking in here to say that the extended limbs and joints and whatnot ARE how nature multiplies work. So stop assuming nature can't do it.
Now make It bigger!
Research the biomechanics of a flee when it jumps...
Mommy, have you seen my
Jumper?
Learn to give.
When we let others gain first,
then we can truly benefit.
Give this to the military asap
Does it scale up?
maybe bow and arrow can shoot even higher.
imagine how high it could jump on the moon!
125 meters, according to the video.
125 meters, 410 feet
I guess you didn’t listen to the video, then.
It was slipped in the last few seconds, he could have been distracted.
And thank you for the conversion to feet, it's late here, too late for math, not up to doing it myself.
It's a fascinating device, I'm curious what payload it can carry. And of course, how much bigger will they get?
Just like the Hulk.
Thing that amazed me most about this video is how low the Jesus statue is.
Isn't this how ticks jump?
That was fun
Um, it lies! That is not the best jumper on earth! You'd get cold trying to wear that!
Air defense decoy 😮
Can one get plans to build this robot?
Apparently (based on another comment I saw) there is MATLAB code available, so, it seems likely that yes? But not sure
"so perhaps the next giant leap in space exploration will be- a leap"
real missed opportunity there
What about the flea?
SURE DO wish you'd given us at least one complete recording of the operation, at least one!
Some of us would like to see the full work cycle, from LAUNCH to LANDING, covering the device at all times during the cycle.
It seems you have attention deficit folks on your team such that you couldn't bear to present the whole thing; just little snippets of it. Phooey.
Document better, Please.
Cope
@@williamchamberlain2263 Educate yourself.
It would be difficult to capture useable footage of it through the whole trajectory. If you frame in 35 meters, the device will be hard to resolve. If you try to follow it, the footage will be blurred and jerky. It seems likely they have more video than we have seen. They might have single shot coverage, but feel it was not great in a TH-cam video.
Would prefer comparisons to non-religious items in the future.
Your over looking the Flea! Which can jump 100 times it's own length that'd be like a human jumping 250ft!
Imagine being that Robot trying to stretch your arm to reach a button and you are 2 inch too far. Welp.... I guess i'll have to jump 30m in the air to reach that button. And this is why Nature never used that design.
This is a cool toy, and certainly a nice feat of material design, but I wouldn't call this a robot...
That's not a robot. It's a spring and an actuated mechanism. But it's not a robot.
In fact I don't even see an inventive step here.
Wonderful. Now let’s weaponize it.
If it doesn't break while breaking the record then it's not at the limit. Close though
any kind of breaking would reduce jump height. If any of its "arms" breaks, energy stored in it would just be wasted.
This saying only makes sense when testing for durability...
but is it a robot or just machine does a single action
What makes this a robot
