1. This video demonstrates the dynamic simulations of the two foldable mechanisms in a commercially available multi-body dynamic simulator called "DAFUL". 2. Three different kinds of motion trajectories were defined for each PM. Pop-out motion from 0s~10s; Swivel motion from 10s~20s; Tilting motion from 20s~30s. 3. Actuation forces were calculated with application to TV mounting device (support...

That thing looks stable enough to do brain surgery!
what's the role of the motors? anyone?
what exactly do the motors do? can someone explain how this works?
покажите работу на дальнем свесе и на ближнем к пружинам свесе. то что на видео видно, можно симулировать фрикционно
what do I have to study to understand this ?
Engineering or more generally, physics
How can pure springs balance a multi-DOF system? It must be using friction too
You can see the motors at the end of the arm controlling 2 degrees of freedom of the nib itself. The Springs are only technically balancing 2 degrees of freedom with the rotating base I think just being friction based.
a pen for astronauts on earth
Whoa... two pivots and friction will do the same, bro.
OvO TIME TO STEP UP MY SOLDER GAME
😅😅😅😅😅well ingormeti0n.Good show 😅😅
Very good invention, it could be used in mega structures or special cranes, or special mechanisms used in miliary & commercial applications., where weight balancing is key. This technique is very clever indeed.
Like mama said, *USE YOUR WORDS* _Descriptions would be better!_
this make me stress
thats si cool
This proves F = -kx in a beautiful way.
I'm absorbed by the strength of this material. A book with comparable insights significantly altered my perspective. "A Life Unplugged: Reclaiming Reality in a Digital Age" by Theodore Blaze
why not just use it the tool in zero G
Ever heard of a steadycam?
great video!
Зачем такая сложность с системой балансиров? Можно было просто ввести в конструкцию кнопку по нажатии которой шарниры разблокирываются и при отпускании её, соответственно, блокируются.
You'll still have a moment of it shifting. For precise stuff, you really want every motion to smoothly start and stop, without shuddering or anything. There's a system that works on this principle for cameras in film industry, used to stabilise the image when shooting scenes.
@@SaphireLattice В вашем видео эта система используется для удержания бор-машинки. Похоже я не совсем верно выразился. Я имел в виду вот что: Вы добились такого баланса, что бор-машина находясь в любом положении которое доступно в этой конструкции, что при отпускании её из рук вся система остаётся в покое не меняя своё положение. Вот я и говорю, зачем так заморачиваться с балансировкой, если можно ввести в конструкцию (не отменяя балансиров) кнопку блокировки шарниров. Лично я бы так поступил. А в конструкциях для камер в кино индустрии, насколько я знаю, присутствует гироскоп, электроника и система приводов. Или я вообще не верно понял ваше видео и в вашей конструкции тоже это всё имеется?
I thought that monitor is counter balanced😂
This is the most overengineered display stand I've ever seen
is this why that one apple stand cost 999?
The fact that you can put your lamp anywhere is pretty powerful.
@@Noconstitutionfordemocrats1🤝agreed
I am looking into these fixtures. Please let me know about the simpler designs you are familiar with that accomplish the same results.
Nice! good job.
The monitor in the background is the Achievia Shimian. It is 27” and has a 2k (or 1440p) resolution. The LG-manufactured panel used inside the monitor (the screen component itself) is the same panel used in Apple’s 27” Cinema Display (now discontinued). I picked up this monitor in South Korea at the Yongsan Electronics Market for 135,000₩, or the rough equivalent of $135. I spent another $89 on a circuit board replacement from EBay that allowed me to overclock the panel to 120hz and I have since used it as my primary center display. The color accuracy is amazing and the refresh rate, while not as high as contemporary displays, makes for an incredible, low-budget gaming monitor. First time I’ve ever seen this monitor outside of google searches (and my own, of course)! Oh, and the included stand is awful.
A similar system was used on drawing boards, as far as I remember.
This is like getting a coin to land sideways
Can this not be achieved with 1 counter weight?
With this system you can achieve different counterweight loads per axis.
This looks.. expensive
Holy shit what a display of physics. Subscribed.
Yep that's cool indeed but wouldn't it come with so much inertia that it would become to cumbersome to use it one handed like that for any precise movements? If it is purely mechanic, of course, but the same platform with powerful steppers and precise drivers would be more than amazing though..
And it even seems that that's already the case! Please a more in depth demo then!
the arm with the pen is a lot longer than the arm with the counterweight. id assume thatd make it a lot easier to move.
I love the way it moves. Don’t know how to describe this, but it really seems like its trying its best

I love science also for this! Thank You!
This is ingenious
You can train an algo to find extent of boarders and do a full sweep of range of motion automatically

Your designs are ingenious

Is this for surgical application?
Are you Vietnames?
Is there any role of friction here? Or are the joints almost frictionless?
the friction term is quite small
Yes youtube, keep recommending me redundant kinematic mechanisms with singularity avoidance. I don't know how these got into my algorithm but I don't mind.
Ay
Nice work. We are waiting for servo motor controlled version.
How can I learn how to develope this? Any software?
use solidworks to learn to design the parts and then u can simulate the movement including forces (including gravity) using solidworks too
@@tarikr5853 Thanks Bro =) A big huge from Lima Peru
This would be a perfect base for a steppermotor driven robotic arm. Very interesting 🤔
No, because the absurd increase in inertia, you need to find a solution with springs
@@polentusmax6100 Yup makes sense. Unless you used some beefy torqy motors as counter weights🤔
If speed is not a requirement which usually is the case with applications that are heavy any way i can't see why not @@polentusmax6100
The perfect idea for Mandark to steal
@@wj11jam78 Ideas should be shared. No stealing required 😑 I Don't wanna make money of this I'm just a hobby robotosist 😉
Loved your design. Could you please give more explanation about weight distribution and spring power?
weight distribution can be confirmed from the 3d software, spring stiffness has to be carefully selected together with the design of its attached points
@@longkang6744 TL; DR: I wont share the design. And that's okay, it's your baby.
spring power? theres no such thing ..
@@typebinI was learning/Curious, I didn't know if its called spring constant or stiffness constant and I asked anyway. I would have appreciated if you had pulled your head out of bull's ashole not being bully here on my 3 year old comment. But thanks for let me know anyway.
@@typebin Smimply educated comment would be much appreciated.
which books can i refer to learn about these counter balance mechanisms?i know about basic 4 bar mechanisms and their inversions etc
Many large industrial robots already use this idea. It's so the servo motors only have to worry about the forces external to it and not the weight of the arms.
