@caseymurray7722

Жыл бұрын

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.

You really helped a lot in completing the levels. Nice work

This man just hooked me up to tell me about jumps for 11 minutes. And I feel like I enjoyed every second of it.

1:03 Aww 😍 I’m glad you included this.

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!

You should do a video on the axiom of choice. The history is nice and the math and logic behind is super cool.

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.

Hello 👋

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.

when i was a kid, i was a big fan of this kind of experiences ! ahaha thanks for your video :)

One interesting thing to note is that humans also use latches! Think about how snapping your fingers work

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?

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.

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.

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.

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.

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.

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!

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.

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… 🤔

@Kepe

Жыл бұрын

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.

This is how the accumulators in an injection moulding machine work.

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.

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.

@samuelpmoran

​​@@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.
