It’s pretty hard to walk on a tightrope but I thought I’d have a go. I set up a bar which is a steel scaffold pole and tried my best to walk along it. Sometimes I could almost make it to the end, but most of the time I did far worse than that. It’s a bit easier if you crouch right down and use your arms to help you balance, but standing up tall makes it even harder. Standing still on the spot for any length of time is practically impossible.
But could I make a device that would help me balance?
I’ve built a couple of projects that used reaction wheels to make a device balance on the spot. This is a wheel which rotates and dynamically accelerates in either direction based on the angle of the device. Force equals mass times acceleration, so we only get a reaction force when the wheel is accelerating or changing direction.
But how big would a reaction wheel need to be to help me balance so I can walk all the way down the beam?

Your hips are like a hinge, which allows the device to think it's upright as long as only your upper body is upright. But if your legs are at a slight angle still, you're not balanced. You need the device to instead stabilize your hips, to keep your legs upright. Not your torso.

I love your balancing machines! Suggestions for this one: 1) Ring of mass instead of spinning death flower. Reduce the mass for same moment of inertia. I would have tried a bike wheel with a vinyl 2" tube filled with wet sand, capped on each end and zip-tied in place of the tire. Respect for the max effort approach, but man that is a lot of cutting drilling welding screwing for the world's most deadly social-distancing encouragement device. 2) Accelerometer mounted on chest to decouple angle changes of the backpack relative to torso. 3) Ankle supporting work boots to help avoid breaking or spraining an ankle. 4) Control test with static mass on backpack instead of control test with no mass on back. I would guess it's even harder to balance with 30kg load on your back. So the improvement would be much larger than you seemed to observe. Keep up the great work! You are inspiring!

@MrMuzza008 Год назад

Real tight rope walkers hold onto a very long bar to balance. You should make a "virtual" long bar. It would be a short bar with reaction control wheels on either end of it to keep it perfectly level and then you hold onto that. When you feel you are tipping one way you would instinctively push or pull the opposite way and the reaction wheels would push or pull back hopefully keeping you upright and balanced.

@prodiver7 Год назад

Just a massy bar that shifts side to side should do it...

Good point! When I was around 16, a friend and I would walk up to a store regularly. On the way there was a metal railing fence about 15’ long. One day we got the idea to try and walk on it (was about 3 1/2’ high if I recall) and each of lasted only a few steps. We tried some more…then went on. But after that whenever we walked up to that store we would give it a try, maybe a few times. Was decades ago, but I recall in about a month of this, we were regularly able to walk the whole length about 50% of the time, and even when we didn’t we got pretty far usually before falling off.

And this is why tightrope walkers have a really long bar. I think it would be much better with a weight on the end of a bar swinging side to side like a pendulum. If it could extend as it pivoted then that weight can be smaller because the lever will be longer, I hope you revisit this.

@kylejacobs1247 Год назад

A ring of mass would be much more effective than radial spokes of death. The radius of gyration of a ring is pretty much R, while the radius of gyration of a bar placed from the rotating axis to the outer radius is R*(1/sqrt(3)). That means for a given diameter and weight, you are only getting 58% of the rotational inertia you could be getting. Put another way, you could probably reduce the weight from 30kg to 20kg with the same inertia by using a ring design.

@AbelShields Год назад

They weren't from the rotating axis though, they started most of the way out so not really "spokes", I imagine the radius of gyration wasn't far off of the radius of that wooden wheel with that setup

@stenzenneznets Год назад

You are absolutely right. I can't belive he didn't design the mass placement this way

@MjuMeli Год назад

Thanks for this comment

@bosstowndynamics5488 Год назад

@@stenzenneznets It's fairly easy to see how he wound up with those long spokes: James is well aware that ring mass distribution is better as demonstrated by his previous 3D printed flywheel designs - they aren't perfect but definitely move the mass outwards This is the first time he's been moving this much mass around with a reaction wheel, so his initial guess at the required performance was low Using his initial guess, he built a flywheel with the mass more or less towards the outside, within the limits of a project he needs to build, record and edit in less than a week with room to spare When that wasn't enough he added steel bar stock to the outside of the wheel When that still wasn't enough he decided the wheel diameter was too narrow so the next load of weight he added also extended the radius, and then a bit more on the outside Basically every time he's added weight he's put the new weight as far out as easily possible, he's just been stuck with the existing limits of the design without modifying the already complete parts. I expect if he did a v2 that it would be a larger diameter ring with better mass distribution from the get go. This is just an inevitable consequence of seeing projects like these - since it's just effectively a hobbyist proof of concept you will inevitably see far from optimised designs even from engineers who very much know all the ways the design is suboptimal.

Just a little feedback from a physiotherapist on this cool project: Maybe Put the wheel down at rear center waist level near the body's COG,and shrink it's size and weight by increasing RPM?

@iwanwesterduin Год назад

It looks like many of the failures to stay on the bar, specially the earlier tries, occur when James instinctively tries to absorb the pushing force by moving his shoulders and hips in opposite directions and thus shifting his center of mass. If you try to visualize the imaginary people standing on either side pushing him back, I'm pretty sure they would find that pushing his hips is more effective than pushing his shoulders in keeping him balanced. So I definitely agree that this would probably work much better with the reaction wheel at or slightly above waist level.

@mal2ksc Год назад

@@iwanwesterduin It would also be more practical for someone to nudge him in the hips or ribs, compared to the shoulders, if the bar is more than 15 cm off the ground. So that would probably seem more "normal" if he's perceiving this as "helpers pushing him back up".

@1mariomaniac Год назад

Increasing rpm brings the issue of acceleration time. In order to gain the appropriate effect you'd need a motor that could reliably bring the reaction wheel up to top speed in a short time. And he already seems to be using a pretty powerful motor, with a 2:1 reduction as well for extra speed.

@hpfred Год назад

I know you usually want a reaction wheel like that higher on the balancing object, but as you mentioned our body isn't rigid so we compensate for a lot of that. So, wouldn't having it closer to waist line maybe better? It would be closer to where our center of mass usually is, and where you would want the most to have those forces helping you balance, no?

@hpfred Год назад

Also, maybe having something like a cage from a paramotor would be a bit safer. XD Would also allow you to make the wheel wider like you mentioned

@nicholasmetsavaht7663 Год назад

As a biomechanical engineer I agree 100% with this, other than the center of mass part if you place the reaction closer to the chest your abdomen muscles would work a lot harder to compensate the external forces, making you fatigue faster, it would work better as a balancing exercise rather than a helping hand.

If you were to make a steel ring to be the reaction mass it would not only have a lot more inertia than the spokes you currently have, it would also be a lot less likely to smack into your elbows

@robertsneddon731 Год назад

The US missile designers (and later space rocket builders) needed to use rotary gyros for attitude control long before cheap electronic IMUs were available. Since mass and volume were at a premium they built the rotating frames from lightweight beryllium alloy and added mass on the rims with very dense tungsten alloy cylinders. Wikipedia has an informative article on the ST-124-M3 inertial platform flown on the Saturn V rocket from the 1960s onwards. My suggestion for a Mk 2 balancing rig would be to lighten the non-rotating parts by replacing the box steel frame with aluminium extrusions and replace the reaction wheel with aluminium spokes or perhaps even a bicycle wheel driven by a pulley belt, then attach lead weights around the at the end of the spokes (or around the rim).

@escain Год назад

I would recommend a linear mass, instead of a wheel: In a rigit robot, the wheel applies a rotational momentum, which directly transfers (by friction to the ground) as a lateral force compensating the fall. In a soft body like a human body, most of the rotational momentum just transfers as bending force on your spin, which is mostly absrobed by it and the legs, putting very little lateral force on your feets. If self-balancing is produced by an horizontal linear actuator (imagine a heavy horizontal bar, that the motor is moving left or right). I believe this would much better transfer as a help to keep balance for your upper-body. Obviously, it can't keep moving left/right indefinitively, so the software must overshot slightly to then recover the center of the axis. You can test this manually, by handling the horizontal heavy bar yourself with two hands. You will notice how easier is to keep the balance with the help of the bar.

@bosstowndynamics5488 Год назад

A linear mass on a single axis would still apply a significant torque to your hips so would have a similar problem but also be far more cumbersome. IMHO 2 key things would make this work far better - a more optimised flywheel as mentioned by others and just a bit of practice, letting his brain get a feel for walking with the wheel on. Admittedly practice would also make him better at walking a tightrope without a flywheel, but it would likely take *a lot* less practice to get good with a flywheel than to walk a tightrope without one.

@DIYuntilDAWN Год назад

Rather than the box steel and steel bars that look a bit like saw teeth, you could use a steel ring around the edge of the wheel (like the rim of a bike tire) to add mass to it and it might be a bit safer. It would also mean most of the mass would be further from the point of rotation of the wheel.

I just found your excellent channel! Having practiced and thought about balancing (myself, using myself, with varied and escalating challenges, tools to assist and give feedback) a lot, I LOVE and am inspired by this idea (and it gives me some new ones)! A couple thoughts that might be helpful: 1. As you said, our squishy, twitchy, uncalibrated, non-rigid bodies tend to react somewhat chaotically w/re: handling sudden, unexpected changes in acceleration..well, to do what gymnasts do, these things are controlled with strong, simple body postures and muscular tension..effectively reducing the number of moving parts while increasing robustness of postural integrity..which simplifies force handling. In your case, consider these tips: - Hips tucked - Tight core - Squeeze glutes - Knees slightly bent - Arms straight - Head neutral If you spend a little bit of time practicing this posture..going over the points of focus repeatedly, trying to strengthen each one and your ability to maintain them all..I think you'll find that it makes your body more straightforwardly compatible with your device. 2. Rather than making your weights heavier or the arms longer, what about maximizing weight distribution toward the ends of the arms? -------------------- Great stuff - subbed! ,{^_^}"

Quite the opposite to your bigger, heavier flywheel proposal, you need a high torque step motor with a smaller, metal flywheel. This will give you the more immediate assistance you need. A motor with enough torque will work without a flywheel, as they deliver quite the jolt, but a metal flywheel is more compact, enabling a mre rapid change of direction response, and will definitely smooth out the effect.

I’m looking forward to any improvements on this reaction wheel balancer lol If looking for ideas for an updated version: Perhaps a ring of mass would be safer to rotate than the current box tubes, maybe moving the reaction wheel toward the hips would allow for better transfer through center of mass and increase accuracy as the leg angles and torso angles are different for balance

@Stoneman06660 Год назад

That's a frightening amount of energy very close to your elbows! Good to see all the safety gear at work during the build though, something that is often missing from RU-vid content.

@talyrath Год назад

Tilt your head back too far and you're going have a bad problem (and will not balance on a bar today).

such a creative idea - a bit scary but super creative . Thanks for sharing.

Nice thing about working night shift is there is usually a new episode about the time I get home.

Get rid of the box steel near the center of rotation. Put all the weight on the outside of the circle. The pack will weigh less and have more power to balance you.

@user-vs8ey9nq2q Год назад

The momentum is made by the X-distance between the tube and the centre of the body mass. While the current device detects the angle of Z axis of the body. So the device won't help when the body is falling strait. Also, it will push the balanced body when it is tangled. Even more, when the body is just started falling and is tangled in a different side, the device will help to fall faster.

its functional and compact as well, which is nice.

this is a very interesting use of this property and i never seen it or the other ones shown implemented in this way! great idea sir!

@TedToal_TedToal Год назад

Your projects are always amazing. I was surprised you didn’t try the traditional long stick to use as a reaction mass, to get a feel for how well that worked and how well you could balance with it. I suspect it works extremely well and might make you wonder why you would even bother making an automated version of it. Then again, why not use a long stick rather than a bunch of small weights on your device? Of course the stick is limited in how much total motion it can go through before it hits the ground, but since angular momentum is conserved, it technically should never go beyond a certain limited range of swing, right? As time goes on you’re gaining more experience so you are probably getting better even without a reaction device.

@wtf235235 Год назад

Hi James, I think adding a cvt will add nice benefit to reach higher speeds to create that force for longer

@gtjack9 3 месяца назад

This would work so much better if the reaction wheel had better leverage, its current centre of rotation is a long way from your body’s pivot point which reduces its leverage on the rotation of your body. That’s why reaction wheels in spacecraft are at the centre of mass. I’d try getting it closer to hip level. That should give you a lot more responsiveness and torque.

@AndreJNick Год назад

When it comes to the tight rope your intuition is usually wrong. most people will try get both feet set down and then try to balance, but that's gonna mess you up more often than not. You wanna regain your balance while one foot is in the air. use it to your advantage.

@rammagaming Год назад

If you try a version 2 of this, put the reaction wheel basically on your butt. Sounds weird, but above your torso isn't really needed for slack line balancing. It can help for sure, but it also just ads another layer of complexity to the mix. I've done circus arts for over 20 years, and most slack liners I know can walk with no upper body help. As long as your feet are placed well, then it just comes down to keeping the legs and hips properly aligned, which the reaction wheel should do if mounted right.

@bheart64 Год назад

To make it compact think about faster spinning counter rotating wheels and use electromagnetic retrogression to create the reaction forces required.

@rts2468 Год назад

It's the mass alone that is helping you get across, if you truly could not do it by yourself. Adding mass will always help in balancing, since it takes more to move you off the beam/pole.

@Eralen00 Год назад

i think tightropes are ropes (aka flexible) so that you can shift the rope itself in order to push your body back toward the center of gravity. In other words, its much harder to balance on a stiff beam than a rope. When you move your feet to the left/right you have a better angle to push against in order to move your body back to the center line. I'm not sure if it makes sense or how to explain it in words

@ArunUdai Год назад

With this much of effort and trials, I think your body has also learnt to walk balanced without any aid.

@nobodynemo9556 3 месяца назад

I think attaching the devise a little bit lower than now, to a weight point, can increase capability of that device and improve stability of the user. Because in that set up that is pushing shoulders and that is too high and can be reason to fall cuz of out of balance

@emma70707 Год назад

I wonder if this could help people with vestibular issues. Very cool!

@liefschneider3123 Год назад

Super cool! Would be cool to see you try out more designs and have a longer beam to test on. Would having more wheels spinning help with reducing the mass?
