For a second, I thought it would be Active Suspension. Seeing that in a small scale would be cool. To me this suspension looks very compliant with terrain but at the same time it doesn't look like the groundbreaking demo's we're use to from darpa.
its really cool , the stability of the body maintained ooufff ... i love to have such a type . suspension system obviously resolves many problems . even this helps in the war filed .... thanks for DARPA's robotics...
Just look at it. Torsion suspension uses a torsion spring with leavers to capture the impact force of the wheel. No need for springs, pistons and rockers. It's lighter and more compact. Look it up.
I got the impression that the individual wheel springs here were computer controlled, so they could be adjusted electronically in real time (making it more smooth than just mechanical suspension). Not sure though.
R u kidding me!?? Suspension is the most ideal addition to tanks. Do you have any idea how much easier it would be to maneuver through all terrain with suspension. You would lock on to target before they even see you.
As a base platform it appears to perform well. However to be useful, you need something on top of it (EOD arm, disruptors, weaponry (if that's your thing)) etc which raises the CoG substantially. Then the large-range suspension works against you (ever seen a Citroen 2CV do some hard cornering vs bumps in the road??) and you run a real risk of toppling. You'd get away with it if you could lock the suspension (which you'd need to use an arm or weapon) but then what's the point.
I concur, I think this works well when you just have a track platform similar to the "Ripsaw" if you've ever seen that tracked offroad vehicle. But like you said, let's say we build a torso-turret on this tank and put weaponized arms, missile systems, or surveillance: the high C.O.G is going to create an overturning moment effect on this style of suspension bottoming the suspension out either forward or backward. And the only solution to fix this is to stiffen suspension considerably or create a torso/turret that moves or uses gyroscopic stability to counter this.
Geckos stick to the wall because of the many tiny hairs on their skin, we created Velcro in the same way. So yeah, look forward to the day it was created over 60 years ago.
Ага. А что тогда на параллельной съемке, когда система выключена? Обратите внимание на черные приводы с тягами к тракам, расположенные сверху на борту.
We must not rely too much on killer robots, it would be dispoyalty and dishonor. Because robots don't have a soul, a heart and they don't know loyalty and honor. Winning wars requires human soldiers who have hearts, souls, and who know loyalty and honor !
I agree with Jan, I can go to my local hobby store and get the same thing for $200. For a bit more, i can get CO2 BB gun mounted and camera mounted. How much did DARPA give to develop the same. Just go to show how how anyone can get funding these days.
Isn't this just the Christie suspension? The one americans rejected in 1920s? Which then forced Christie to license his system to USSR, where it became the BT series and the eventual T-34.
M1A1's didnt use spring suspension and this is possibly part of the selective compliance trend seen with LS3 "big dog's" locomotion as active damping. otherwise its just spring suspension imo lol.. if you look up the m1a3 variant their hydropneumatic suspension thing looks like a possible attempt at variable compliance incorporation. cool idea to put a microcontroller/ASIC on the job if springs and linear actuators or even solenoids can pull off a variable spring-tension knockoff!
На параллельной съёмке, амортизация отключена, как там и написано... У нормальных амортизаторов можно менять жёсткость, сверху - жёсткость на максимум выкрутили, внизу на минимум, например. вот амортизаторы похожие на те что в видео extremercmotorsports. c o m /ccp5/media/images/product_detail/HPI-A712-Shocks-300px.jpg (пробелы в домене уберите только) Чёрных приводов что то не вижу, подскажите, где они?
i have been wondering why they did not do this decades ago its simple weight of vehicle=suspension tightness you can even go electronic with weight compensation decrease internal orface to make up for some one or thing added to its back. on a bigger scale i mean. vehicles. ambulance ect.
на 0:15 сек. я вижу только особенное крепление последнего катка, там просто места другого нету чтоб закрепить его, поэтому его амортизатор на чёрную штуку такую видимо придумали крепить... А поперечного крена на мягкой независимой подвеске, да ещё в такой конструкции (когда много колёс) практически не будет...
Erm... so you're saying you designed a suspension for robots that looks and works like the suspension for late WW2 tanks? So innovative... shame on you guys.
чет мне кажится новенького то нихрена не изобретут, в СССР начиная с 70х был один дядька так он наверное все варианты колесных движителей уже изобрел, осталось только и их спиздить и ура дарпа чет покажет.
That's the thing. I know I will never receive a letter for employment from them, so what does it matter? ! lol. What I said is true and anyone that knows what I'm talking about will agree. Besides, I don't have an idea from a better mousetrap that I didn't pick up from somewhere else online, so it's not even my original idea. But it does piss me off that these guys make tons of money to come up with shit like this and I'm struggling to get through college. Fuck them.
Strange way of asking to be considered for employment; ridicule. Oh well, if you got a better mousetrap I'm sure someone will beat a path to your door for it.

I read their paper and it is more about the long suspension travel it could provide.

Any development of robot platforms is a good thing IMO. More robots in the field ASAP.

Да тут много кто не читал, судя по комментариям :)
На самом деле реально крутая штука, и потенциально полезная в народном хозяйстве.
About damn time. I still think it could be more simplified though.
R u kidding me!?? Suspension is the most ideal addition to tanks. Do you have any idea how much easier it would be to maneuver through all terrain with suspension. You would lock on to target before they even see you.
Was I the only one to notice servos controlling each individual wheel of a christie suspension unlike the "nothing new" commenters?
yessssss!!! i can go off roading with my tank now
¤Φ¤√
Great chassis !!!
Very impressive, actually.
Nice! I could use this as an upgrade feature in my Robot FPS game!
Is that traditional Christie suspension?
Torsion bar :)
beautiful
Hmm, maybe not, I'm also confused now as to how this is new.
it slings forward really hard on stops i wonder if they can program the suspension to tighten while stopping
As an EOD Tech. I would give my first born to actually have this in the field.
There is a mechanical way to do this, but not at this extent!
Great job :)!
This thing really is great, how much does it cost $300,000?
Pretty cool.
What sized coilovers are those?
can any one tell me clearly .. wat is suspension is all about
and what type of springs these are ... plsssss
Advanced suspension is called Christie suspension, and its 80 years old

Exactly!
Later, it substituted with torsional suspension, wich hawe less mass, and more moving lenght.
Sory for my english.
What do you mean?
SICK JUMP!!! 1:15
Plans please
I would like to build something similar to that
whats the load limit on the modle in the video?
Probably low because the spongier the suspension the harder it is to place a heavy load on it without it bottoming out.
What are the solidworks files to this, to include into a drone design?
This is quite genius, but what if it somehow flips over?
So it's a scale Ripsaw?
great music!
good job - like
Geckos stick to the wall because of the many tiny hairs on their skin, we created Velcro in the same way. So yeah, look forward to the day it was created over 60 years ago.
Ага. А что тогда на параллельной съемке, когда система выключена?
Обратите внимание на черные приводы с тягами к тракам, расположенные сверху на борту.
WOW AMAZING!!
What do they mean by "suspension" system?!!
Sorry, was this a video just showing wheel-specific suspension? My brother's remote-control tank has the same system, and that's five years old :/
Плохо, что не понимаете.
Они показывают подвеску, в которой каждый каток - управляемый в зависимости от рельефа местности.
I have made lego tank suspension like this :)
so how many millions had spend to rediscover suspension in smaller scale?
they will use it to carry kit or for bomb disposal
If you look carefully you'll see that only rear wheels are connected to servos
я вот сам не пойму, что они показывают? машинку на управлении или подвеску?
We must not rely too much on killer robots, it would be dispoyalty and dishonor. Because robots don't have a soul, a heart and they don't know loyalty and honor. Winning wars requires human soldiers who have hearts, souls, and who know loyalty and honor !
I agree with Jan, I can go to my local hobby store and get the same thing for $200.
For a bit more, i can get CO2 BB gun mounted and camera mounted.
How much did DARPA give to develop the same. Just go to show how how anyone can get funding these days.
It already has.
What's the name of this song? I need it next time I'm practicing sword moves on a mountain top
Isn't this just the Christie suspension? The one americans rejected in 1920s? Which then forced Christie to license his system to USSR, where it became the BT series and the eventual T-34.
I'm surprise they are still playing with RC toys, I want that job, where do I sign up?
Abraham tanks already have this though
Darpa invented what already exists. lol
but why did they put this out now
M1A1's didnt use spring suspension and this is possibly part of the selective compliance trend seen with LS3 "big dog's" locomotion as active damping. otherwise its just spring suspension imo lol.. if you look up the m1a3 variant their hydropneumatic suspension thing looks like a possible attempt at variable compliance incorporation. cool idea to put a microcontroller/ASIC on the job if springs and linear actuators or even solenoids can pull off a variable spring-tension knockoff!
cool
I built something like this.
what type of suspension is this?
Что "Это"? Компьютеризованую подвеску с управляемыми катками? Может и не они, но довели до действующего образца - они.
Ты на БМП на наши глянь, там тоже самое. Вот только не помню какая из БМП умеет ими управлять.
what is motor?
were.... I understand my grammatical error, yet acknowledge that it in no way negates my intent...

they actually did this back in 1931 with the christie m1931 tank, also with the soviet BT variants (bt 4, 5, 7)
На 15-ю секунду обратите внимание.
И на вид спереди, если считаете, что просто "амортизация" - где поперечный крен?
Yup that's why WWII tanks didn't have their springs locked up.
на 0:15 сек. я вижу только особенное крепление последнего катка, там просто места другого нету чтоб закрепить его, поэтому его амортизатор на чёрную штуку такую видимо придумали крепить...
А поперечного крена на мягкой независимой подвеске, да ещё в такой конструкции (когда много колёс) практически не будет...
*Laughs in Walter Christie*
27 people didn t get into collage ..
How many trillions for this toy tank?
The best bit is that it probably cost 5 million dollars :)
It's like an electric slug.
They didn't invent squat! that is the very same suspension design as the Ripsaw invented by the Howe brothers.
Вы хотите сказать это активная подвеска?
Помоему здесь обычные пассивные амортизаторы и всё..
That's just Christie suspension
I mean, suspension vs. non-suspension? What kind of demonstration is that? WTF?!?
Все просто. Больше скорость - меньше ямы
More like Derpa
i bet this will be a mobile mine... like the germans made except with ai
it should be incorporated into toys first....
progress
Забавный аппарат
Erm... so you're saying you designed a suspension for robots that looks and works like the suspension for late WW2 tanks? So innovative... shame on you guys.
Нет, они первые поставили это на поток.
LOTS of tax money wasted to prove that a good suspension makes for a better ride!
Looks alot like Ripsaw....
И что они серьёзно думают что они первые это придумали?
It's not torsion bar suspension. This uses rockers with spring and pneumatic cylinders. Get your facts straight.
Still, not-so-freakin-'original.
теперь понял. описание не читал, каюсь
чет мне кажится новенького то нихрена не изобретут, в СССР начиная с 70х был один дядька так он наверное все варианты колесных движителей уже изобрел, осталось только и их спиздить и ура дарпа чет покажет.
dear fanta...
@DARPAtv stop working on this stuff and create a mecha like the Japanese Kuratas but make it practical and not a toy XD
now it just need a gun...
gotdam son i know how this shit work got it on my CHEVAY and 4wheeler waste of taxpayer dollers
now when my welfare check gettin here
neato, the machines we will destroy in the future when a termintor comes back in time

And hackers.
ahahahahaahahahahahahah
