That actuator which controls not only movement but also strength is fantastic idea.
Jarek F controlling strenght isnt the difficult part, you just use more or less juice. the difficult part is that to get high torque you needed gears, but gearing makes something non compliant and reduces speed. how you get lots of torque and yet avoid high gearing is the mystery part that apparently the bear actuator solves. though i am sceptical of that claim, you cannot cheat electromechanics. if you are willing to use way more power (i.e. be inefficient) you can have a high torque motor with little or no gearing. of course that would be a problematic approach for something supposed to run off batteries (which is probably the reason they didnt).
Stop this bullshit about "cheating" electromechanics.
Any engine has a wide torque and speed range it could be applied to. If you want, you could manipulate this diagram by adding a gear ratio. But there are a tonn of cases when you don't need to, like electric cars are not using transmissions.
MrGarkin the cheating electromechanics part is getting high torque, no gearing, low power and high speed in one small package. you can usually get 2 or three of these, not all of them. electric cars are not different.
Having a high gear rate doesn't necessarily make it impossible to backdrive an actuator. All you gotta do is spinning the motor backwards when enough resistance is applied to the output side. The trick is having an accurate and quick feedback.
Alex Young this is not advisable because you would be fighting motor inertia with high power requirements to prevent your linkage/gearing from breaking under loads your kinematics can not comply to. in any case that is not what they did, you would have heard the motor whine if it was geared.
"humanoid robots are too expensive and complex and they fall over :'( :'( :'( "
...meanwhile, in boston they have an untethered humanoid robot that can backflip and 360 no-scope from a ledge
But they still fall over, but they do not share those videos.
some humans would fall over in conditions such as being shoved, running on rough or icy outdoor terrain, or endlessly being experimented with to see what it takes to make you fall over. Personally, i'd probably break my neck trying to do a backflip
The 360 noscope is so important! In your comment!
Luv it! 👌😂
spot can get up, atlas can also get up, and i ain't sure of de robot with wheels from boston dynamics can get up but i think it can
@@MonkeyKong21 it's a software problem, yours just sucks
Come on guys stop the hate ! We know that boston dynamics owns the game but these guys are doing a great job.
It's like laughing at Rocket Lab just because SpaceX does better
Steak Saignant, idk if thats an accurate comparison! rocket lab is pretty cool!
Elon Musk vs Jeff Bezos would be a much better comparison
neither of which gets old :))
@@EngineeringTechnikcom *Funded by DARPA aka the American taxpayers.
@@EngineeringTechnikcom I said nothing about the value of the program, just that it was funded by DARPA (before Google ever threw their hat in the ring). No need to be defensive. I like Bruno Mars, too.
a truly innovative actuator !!!!! Nice work!!! Can't wait for it to be used in many different applications~
Cant wait till this machine is tossing me off. Anticipation for the next gen robots is unreal. Women will be become obsolete
I watched this after the boston dynamics videos and I can't stop laughing
Funny, I also watched it after the boston dynamics video, but Im not laughing at all. I think these guys are on to something. Its simple, cheap, effective and relatively versatile. OTOH, those BD 4 legged robots do look super impressive, but we can only guess what they cost and IMO are a solution looking for a problem.
I watched it too after boston dynamics. yeah it looked unsophisticated at first but then I liked the simple ideas here that use the natural properties derived from structural design and materials.
That natural spring and dampening is pretty fucking cool. Don't underestimate the difficulty of achieving that mechanically.
@@vertigo2893 Well I suppose money/budget isn't something that concerns the military :p
The real thing that will make them rich and famous is those compliant actuators
Well, Boston Dynamics is way ahead of the curve, but i like their ideas too. maybe for different applications..
I beg to differ, these actuators are really impressive. I wouldn't be surprised if Boston dynamics started using them in their robots
Mik Wind The actuators that Boston Dynamics uses already offer active compliance, which is the only selling feature these have.
Morph Verse I was just about to say that how can he forget Boston Dynamics does that mean Boston dynamics.isnt real or.....
Bainsworth they're buying everything.
I believe Boston Dynamics already use force control instead of position control. Otherwise, it wouldn't be possible for their robots to behave like that.
1:43 Humanoid robots:
"They're too expensive
Too complex
...And too expensive"
Lol
I noticed that too
Basically. The only commercial bot that does all this is a dog robot from Boston and its costs tens of thousands of $$$
BEAR is a real good idea with a ton of applications.
Andre Cabezas And late to the game. Equivalent devices have existed for a decade.
Matthew McKellar let's see the price tag and the real application to judge.
Andre Cabezas a good specific example of a recent robotics company to do this is RobotiQ, who offer active compliance on their actuator's, but the concept originates with the SCARA arm as designed by NEC back in 1981.
A link to RobotiQ talking about active complance is here: www.google.com/amp/s/blog.robotiq.com/bid/69962/How-Do-Industrial-Robots-Achieve-Compliance%3fhs_amp=true#ampshare=blog.robotiq.com/bid/69962/How-Do-Industrial-Robots-Achieve-Compliance
I have however actually used a Reis robotics arm before which was programmed using a puppet mode under active compliance.
Matthew McKellar thanks for the comment
Bear bldc motor and magnetic pole stop and encoder ...
When comparing NABi and other UCLA bots to Boston Dynamics' stuff, keep in mind that these are designed from a goal of being low cost. It's like comparing a luxury car to a bicycle. Both will do the job they're meant to, but with a difference in mechanics and cost.
Your Boston Dynamics dog-bot will NOT be cheap.
Congrats! You made the first spider crab robot!
To be able to construct something that dampens pressure but at the same time can spring load a lot of force In literally the size of a joint for the machine is an incredible feat in robotic engineering. Very proud they’ve created this.. it has now revolutionised the way robots will move. With perfect precision.
It is easy to see that one day humans will be surrounded by many different types of robots. We are creating a new culture. Exciting!
It's tough to make a walking bipedal robot if you neglect the importance of the dinamic strength in bipedal feet. That said you guys still have done an amazing job! I personally can't wait to see what else you guys do with that B.E.A.R actuator! Mad probs!
great talk, one of the best speakers! and that actuator really is breathtakingly "organic",great job!
10:00 damn he missed his chance to say: "Let's put a smile on that face!"
At the moment, this is the best comment in this video.
How are people not cheering for this dude. This is amazing.
oh wow, love the BEAR motor! That's perfectly solving the stiff look and behavior of robots.
Guys, great job.. Not using just gear motors you did a great job..this kind of motion control can give us almost more than 1000 types of motion controls. Very useful for space science. As you shown single arm can be used for in different ways..it's really amazed everyone. Best luck
Those actuators are gold!
When that toddler cheered at the robot kicking the ball it was just heart warming.
The motion of these robots will actually be revolutionary. It can adapt to any type of environment and change its form/motion for the intended purpose. You put two finger like claws and this could do anything you want or hang from the ceiling and change electric cables.
Gotta say, these guys r killing it. Good job.
Really amazing stuff and that presenter is awesome
@1:43 they're too expensive, too complex and too expensive. :D
Wow.. the BEAR actuator is quite impressive!
this is impressive! great work!
@2:47 "your left and L I G H T R E G"
Hold up
*R E G*
engrish
Spoonerisms are very common, especially in nervous people.
Lol he isn't a native american, come on :)
I laughed to start with but that actuator is very cool. It’s like taking robotics back to first principles, which I honestly think has been needed.
I say this is better than boston dynamics, because it is definitely cheaper to make, with open loop it is already stable, great job with the actuators, love to see how it will continue to develop
Their new BEAR actuator is definitely their coolest thing. Changing mechanical properties on the fly can make robots much more nimble, flexible and fast. This can be a breakthrough in robotics
Without a doubt! And not just robotics either. Suspension, bumpers(?), aviation (imagine the type of wings you could make), renewable energy, prosthetics, exoskeletons and even teenager proof unslammable doors! The possibilities are endless. I want some
Crazy robot and really cool motion
The BEAR actuator is a great idea, I am wondering what the difference in power consumption would be vs a traditional motor and could the actuator be scaled smaller.
Awesome. Lots of potential there
알프레드는 여러곳에 쉽게 적용해 쓸수 있을거 같습니다.
That is the amazing thing about robots. Yeah a general purpose robot is great but we can design them to be application specific. This is amazing!
That actuator is incredible.
존경합니다, 홍박사님! :D
Still prefer Boston Dynamics
These two companies are in different pages. They are not competing whatsoever -- rather complementing.
I agree. Boston Dynamics has mainly a quadruped (SpotMini) and a humanoid (Atlas). Both of those are more conventional ideas for both of those types of robots, and, of course, well refined. This company is experimenting with unconventional types of locomotion which will almost certainly have a wide range of possible use cases in the future.
at least you get to see different prototypes and these are not so bad.. everyone has to start somewhere right?
That jumping robot with the wheels for feet from Boston Dynamics is amazing..
As for a firefighting robot for ships a robotic arm that runs on a track on the wall or ceiling would seem better then a robot walking around with a hose that gets caught on everything imo.
Have a water connection in each corner of the room or where to best allow for best coverage of the room so the robot arm on the track can hook up to water,foam ect to fight the fire...
If the tracks were put on all ceilings through out the ship the robotic arm could also be used to move cargo through out the ship through the narrow passage ways that would other wise have to be done by hand....or man lol....like carrying an injury person.
That what I'm saying talk to me when ya beat Boston dynamics
the BEAR actuator is actually really cool
There's going to be some mind bendingly weird robots in a few years, things we would never have imagined!
All valid and important research! Awesome!
I'm very interested in see how these actuators works. (Internally)
So amazing. Such an awesome presentation!
BEAR is amazing! Can't wait to see more applications of it.
Highly impressed by the flexible and noiseless control.
1.they're too unstable
2. they're too slow
3. they're too expensive
4. they're too complex
5. they're too expensive
I'm sure henry ford heard the same comments xD
Also, they are too expensive.
I don't know if they are unstable, slow or complex, but I'm pretty sure they are too expensive.. In fact, they are twice as expensive as they are unstable, slow and complex..
It's like they are back engineering evolution. Very cool!
That actuator is cool!!
This is actually a great idea for a different use. You can't laugh at these guys because the more different inventions, the better it is for science. Just until they finalize their product, im sure this cover weak points that the boston robot has. Thats how inventions works.
wow. that actuator is amazing. haven't seen anything ever like it on all the robot videos out there. that actuator seems like it's a big big deal ( the robot not so much but who cares ) . very very amazing actuator. wish he went into more detail about the physics and feedback of it.
I wish I could find more information about the BEAR actuator.
So in a few years we'll have Atlas robots equipped with BEAR actuators (and A.I.) frickin running around and jumping 20 feet high doing flips... Robot Olympics!!!
I wouldn't call it "revolutionary," but it certainly looks promising. Wish you had more than two days to play with it, looking forward to seeing what you do with it in the future.
Its all fun and games until somebody puts a spinning blade on top of it.
If the robot is a demonstration part of these actuators these guy's are on their way for an actuator business, Just selling them be interresting.
boston dynamic totally beats all biped researches in the world cuz not only atlas walks very well it does parkour too like backflips and one leg jumps in such obstacles
yea and we need robots that make parkour very importan for society by the way i was been sarcastic
The bear motor, or whatever the acronym is, is the only interesting thing here. Everything else is way behind the curve, not just in relation to Boston Dynamics, but even hobbyists can create better robots.
You need omni-rotational joints and bio-mimicry to have a successful bipedal robot. Boston doesn't yet implement this on Atlas, but even they have a better bipedal than what you've created.
Sorry to be so critical, but you're doing what hobbyists have far surpassed, and hobbyists do it with their own money. Like I said, only interesting and new thing here is the bear motor, and I wouldn't be surprised if someone quickly re-engineers it.
At least Boston gives us interesting updates, like a jogging Atlas. Can NABi or ALPHRED jog?
You are so right! I've noticed in the past the huge difference between human muscles and motors, but I thought that pnuenematics would be the answer. THIS ACTUATOR IS AMAZING, & QUITE AHEAD OF ITS TIME!
Well, I'd say the actuators are more than interesting.
in my opinion Nabi is a great advancement as compared to Boston Robotics' Atlas and family only on one and most dominating parameter - the cost!
with the new actuator, they can change the game!
basically, it is direct drive motor(maybe with some reduction). should be used for ages now for that kind of applications
i will take this technology any day if it's gonna save me half the price.
So sick. These are the type of simple elegant designs that will have useful robots massively deployed. (Cheap to manufacture and repair ) global impact alphred and nabi. And BEAR omg the future is here.
Interesting leg movement. This one and the Google one have very different walking legs to 'conventional' robots I've seen here on youtube. And both Google's and MIT's are very different from each other too.
Whoa... I didn't think like this amazing actuator like this... Last year, I went to your lecture in Ulsan, Korea because l'm a great fan of you and robotics! l'm so exciting what you'll lecture in this sep.22 talking in Ulsan. See you then, professor!
온라인 수업 듣다가 왔어요!
Now I can see the future of fluid motion animatronics!
Actuators for the win.
Took long enough for people to realize we don’t need human like robots but spider looking robots
"we can't kick the robot dog over anymore" because this act is following it up.....
I have a Bioloid built into a 22DoF humanoid with inverse kinematics. Many of the robots in that competition were built using the same Dynamixel servos that I use.
'Real'ly cool stuff here.
You guys with the BEAR + Boston Dynamics can seriously change robots for the better. If you changed this from a race to a team effort, that will make these robots so much more advanced! Just think about it, Boston Dynamics has robot stability and movement down, but you have the BEAR, and if you put those together, it would be great
It's crazy that the drone community is mainly hobbyists in workshops and they've advanced so much in just 10 years,
while robotics is scientists in Universities and it seems like not a lot has changed in the last 50 years?
Here is our breakthrough technology... only good for flat surfaces.
He mentioned a naval application on a ship. A custom build for that, or a submarine could be a nice fit. I can imagine in an emergency situation the robot bringing oxygen tanks to trapped sailors, maybe cutting torches?
it's just a revolution. finally, robots will enter into everyday life!
T-800 crying with laughter...
I love how these guys use dynamixels for most of their robots and bscly created a new actuator based on the many tricks a dynamixel has.
That bear actuator shit is incredible...
Watched this... imediately searched "robots falling down"
This is so fantastic. Love the motor especially, would love to mess around with some.
This is actually pretty damn good.
"Left and light reg"
🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪🍪
Ok these are better Than some of the Boston dynamic ones
One thing I noticed, they do love their acronyms
Pretty good. Keep going.
Yes this is amazing it should go in every robot.
2:47 "your left and LIGHT REG"
lmao
I like the simplicity of these robots, the Bear motors are really a breakthrough. Curious to see what will happen when these motors become available to the open source communities
Are they gonna do prosthesis with the actuator? It could be a good fit.
This is also the more elegant alternative to "artificial muscles" and I totally bet on it. Robots were a bit underwhelming but let's see what they do next. I just wonder what it could achieve with the software and controls of let's say Atlas. Anyway we just have to wait and see
Hmm? I think you guys should get in touch with Boston Dynamics. Their Bipedal robots don't fall down.......
1:35 - They're too expensive, Too complex, and they're too expensive... hmmm ok..
:P
They just invented the easy-ease of robotics
The backlash on their drive still leaves room for much, much improvement.
Genesis LiveDrive is way ahaed of their game.
Nice concept. If all goes fine and dandy I can shameless see an improved version of this being helpful and modestly popular 20 years ahead. There are always unsuspected hurdles and caveats, of course, but given that these models rely more on their inherent-by-design stabitily and functionality, whith additional improvements they could be something useful, at last.
In any case, the more the better (in the early years of automoviles there were many types of cars, even electrics ones, even those that worked with steam engines...) and here we are.
What a great idea.
While Boston is way advance, I see this guy's making real world robots which are much cheaper and gets the work done
What's the difference between a BEAR and an SEA(Serial Elastic Actuator)?
Those BEAR actuators could be really useful for suspension in vehicles. I would love to see this more widespread
People seem to think the Boston Dynamics robots always run perfect. You don't see many of the failures.
If navi is this guys personality, I want it
Is it just me or are the acronyms slides a reference to "Kids Next Door"?
"We need bipedal robots, but they are hard to build." Solution: Rename legs to limbs and make a 4 limbed robot!
Totally makes sense
Great actuators, but robots themselves are still too raw. Looking forward to new developments.
Forget the robots, these actuators are amazing!
Good actuators. Working on any electromuscles?
The BEAR actuator is extremely old hat, it is cool, but equivalent devices have existed for a decade already
well touchscreen was also an ancient idea, yet the apple stuck it on the phone and called it revolutional
:23 Apple didn't revolutionize touch screen though. They popularised the marked for smartphones. What you are saying is equivalent to "Paint was also an ancient idea, yet Henry Ford stuck it on a car and it was revolutionary"
Matthew McKellar, I meant that more as a joke than a direct comparison.
:23 Forgive me for the misunderstanding then.
I don't think that actuator is working quite the same way as a standard feedback loop although I could be wrong.
