- The use of ground robots in military explosive-ordinance-disposal missions already saves many lives and prevents thousands of other casualties. If the current limitations on mobility and manipulation capabilities of robots can be overcome, robots could potentially assist warfighters across a greater range of missions. DARPA's Maximum Mobility and Manipulation (M3) program seeks to create and demonstrate significant scientific and engineering advances in robot mobility and manipulation capabilities.
This video shows a modified iRobot 510 PackBot equipped with an advanced suspension system maneuvering on a test course. The compliant suspension improves the robot's mobility over rough and uneven terrain. The technological enhancement enables faster transit speeds, climbing of very steep slopes, improved heading control, greater accommodation of debris entering the suspension and reduced impact forces on carried payloads.
M3 is a research program aimed at improving robot capabilities through fundamentally new approaches to the engineering of better design tools, fabrication methods and control algorithms. The program covers scientific advancement across four parallel tracks: design tools, fabrication methodologies, control methods and technology-demonstration prototypes. The prototypes demonstrated are designed to test technological advances in robotics across a range of functions, and are not necessarily intended to enter production for military use.
The DARPA M3 performer for the Advanced Suspension for Improved Mobility system is iRobot of Bedford, Mass.

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.
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.
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.
Nice! I could use this as an upgrade feature in my Robot FPS game!
What are the solidworks files to this, to include into a drone design?
About damn time. I still think it could be more simplified though.
it slings forward really hard on stops i wonder if they can program the suspension to tighten while stopping
Да тут много кто не читал, судя по комментариям :)
На самом деле реально крутая штука, и потенциально полезная в народном хозяйстве.
Great chassis !!!
Very impressive, actually.
can any one tell me clearly .. wat is suspension is all about
and what type of springs these are ... plsssss
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.
beautiful
Pretty cool.
What sized coilovers are those?
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.
what type of suspension is this?
WOW AMAZING!!
ARPA had inspired me within networking, this robot is outstanding to walk though the Mars ... To walk thought the Venus or Mercury we need to use special materials like wolfram, which can work on the higher temperatures, which is not required within the planet Mars ...
yessssss!!! i can go off roading with my tank now
¤Φ¤√
good job - like
great music!
SICK JUMP!!! 1:15
As an EOD Tech. I would give my first born to actually have this in the field.
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.
Hmm, maybe not, I'm also confused now as to how this is new.
So it's a scale Ripsaw?
Is that traditional Christie suspension?
Torsion bar :)
Exactly!
Later, it substituted with torsional suspension, wich hawe less mass, and more moving lenght.
Sory for my english.
What do you mean?
я вот сам не пойму, что они показывают? машинку на управлении или подвеску?
There is a mechanical way to do this, but not at this extent!
Great job :)!
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 :/
What do they mean by "suspension" system?!!
they will use it to carry kit or for bomb disposal
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 !
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.
Advanced suspension is called Christie suspension, and its 80 years old
This thing really is great, how much does it cost $300,000?
so how many millions had spend to rediscover suspension in smaller scale?
Ага. А что тогда на параллельной съемке, когда система выключена?
Обратите внимание на черные приводы с тягами к тракам, расположенные сверху на борту.
what is motor?
cool
What's the name of this song? I need it next time I'm practicing sword moves on a mountain top
I'm surprise they are still playing with RC toys, I want that job, where do I sign up?
I have made lego tank suspension like this :)
If you look carefully you'll see that only rear wheels are connected to servos
Плохо, что не понимаете.
Они показывают подвеску, в которой каждый каток - управляемый в зависимости от рельефа местности.
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.
It already has.
This is quite genius, but what if it somehow flips over?
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

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.
they actually did this back in 1931 with the christie m1931 tank, also with the soviet BT variants (bt 4, 5, 7)
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...
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.
Ты на БМП на наши глянь, там тоже самое. Вот только не помню какая из БМП умеет ими управлять.
Was I the only one to notice servos controlling each individual wheel of a christie suspension unlike the "nothing new" commenters?
Что "Это"? Компьютеризованую подвеску с управляемыми катками? Может и не они, но довели до действующего образца - они.
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.
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!
Вы хотите сказать это активная подвеска?
Помоему здесь обычные пассивные амортизаторы и всё..
I built something like this.
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.
Забавный аппарат
It's like an electric slug.
Все просто. Больше скорость - меньше ямы
progress
The best bit is that it probably cost 5 million dollars :)
How many trillions for this toy tank?
They didn't invent squat! that is the very same suspension design as the Ripsaw invented by the Howe brothers.
*Laughs in Walter Christie*
were.... I understand my grammatical error, yet acknowledge that it in no way negates my intent...
Нет, они первые поставили это на поток.
27 people didn t get into collage ..
More like Derpa
it should be incorporated into toys first....
i bet this will be a mobile mine... like the germans made except with ai
теперь понял. описание не читал, каюсь
That's just Christie suspension
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.

И что они серьёзно думают что они первые это придумали?
Looks alot like Ripsaw....
dear fanta...
I mean, suspension vs. non-suspension? What kind of demonstration is that? WTF?!?
EOD
lol your thumbnail image made me blow over the monitor
now it just need a gun...
neato, the machines we will destroy in the future when a termintor comes back in time
LOTS of tax money wasted to prove that a good suspension makes for a better ride!
And hackers.
@DARPAtv stop working on this stuff and create a mecha like the Japanese Kuratas but make it practical and not a toy XD
ahahahahaahahahahahahah
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.
Ripsaw Copy....
My robot will kill it (battlebot)!!! muahhahhahhahaha
It's not torsion bar suspension. This uses rockers with spring and pneumatic cylinders. Get your facts straight.
Still, not-so-freakin-'original.
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.
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
