Elon Musk Drops NEW OPTIMUS Update!!

[@stucooper4132]

When Optimus gets full hip extension with full foot articulation it will be a game changer for speed and fluidity

[@KCJbomberFTW]

What do you mean full hip

[@Dave5843-d9m]

It walks like an old man with diabetic neuropathy and Parkinson’s because there is no real proprioception from joints bones and muscles. Our central nervous system has a huge amount of signal feedback that allows us to walk and balance.

[@KCJbomberFTW]

@@Dave5843-d9m it actually has stress sensors and touch sensors on its hands and feet’s the same exact way we do

[@rodneylee4026]

Needs more swivel in the hips for efficient strides. It also could use some spinal joints, at least one mid back.

[@Art-AI-and-beyond]

It actually looks better in slow-mo. Still a ways to go but very fluid all the same. I can actually image when this its really dialled in and the gate is a nice confident stride it will be mind blowing.

[@mrleenudler]

*gait (sorry)

[@ThePowerOfTesla]

I want to see Optimus wearing branded trainers. It can start earning already.

[@tonyduncan9852]

They would have to be perforated to allow air in to the liquid coolant heat exchanger. For ease of dressing styling, the outflow should be through the flexible neck shroud. I wonder whether the Red Dwarf 'Kryten' method will be applied to recharging. 😎

[@FrunkensteinVonZipperneck]

Bent knee. Oppy is 175cm. Straight leg, like a human? Or 175cm floor to skull top with knees flexed?

[@ernestoherreralegorreta137]

Thought so too.

[@pdloder]

It's ~two feet - Scott's being dumb - if it was one foot, that would only bring the rear foot up in line with the front foot - but it goes completely past that and the heel lines up with the front toe - that TWO feet.

[@yOkay_]

Now it walk like 70 old person. Progress!

I agree, most likely, but possibly just directing were the robot is going, not how it walks.

[@Khyrolix]

I think it'll be cool if Optimus charges via feet by stepping into a wireless charging pad the size of a standard scale

[@clashgamers4072]

Wired will be faster and it can be trained to go plug itself.

[@briandoe5746]

The bots will not be battery constrained. 95% of what it does it could easily do on a tether. Being mobile is a massive benefit. A one hour battery with the ability to plug in at whatever workstation it has will cover 98% of all use cases

[@kahvac]

These are the good ole days !

[@avalonhomestead9077]

Remember the more they do things like this becomes learning for the bot. Probably this was a test to how well the video training is converting to actual movement.

[@rodneylee4026]

Eventually the bot will start suggesting its own enhancements. I need more ankle rotation please.

[@jjamespacbell]

The short legs and large torso remind me of a college I used to work with. When we were standing up I was 4" taller than him, when we sat down he was 2" higher than me. The robots frame maybe out of proportion for the "average" person but well within the range for the human population.

[@danielmadison4451]

Love the arm swing looking at the shoulders.

[@czarkbrooks]

The gait reminds me of walking on black ice (something we are familiar with in OR). That prompts the thought that they may be planning for minimal or worst case friction, to be safer against falls.

[@FrunkensteinVonZipperneck]

In England, sneakers are called “trainers.”

[@privateerburrows]

The reason there's AC converters in Tesla's is that it uses AC motors. NOTHING to do with charging. If charging source is AC it gets immediately bridge-rectified to DC. In the case of Optimus, if the motors are AC (or brushless DC, which is a misleading naming convention, as "brushless DC" is AC; just trapezoidal wave instead of sinusoidal); so I don't know because I don't know what kinds of motors are used in Optimus. Plain old DC motors are unlikely; and stepper motors are like switched DC driving them, but they are not the most efficient motors; can have heat distribution issues; so I'd be inclined to assume they use miniature versions of Tesla car motors (which are a strange blend between AC induction and synchronous AC motors), and to drive them they'd be inverting DC up to AC.

[@ufo2go]

Wow. I bet you have an oscilloscope in front of you Dan! Scott: Stand aside. John: Get this man on an episode.

[@privateerburrows]

@@ufo2go Haha, I don't have an oscilloscope at home; but I worked as an electronics design engineer for 25 years, until the infamous pandemic forcibly retired me.

[@MichaelDeeringMHC]

The fans are for the computer. Charging cooling is done by tethered external cooling hoses.

[@jjamespacbell]

Upgrade to self replacing battery packs not need for AC/DC conversion, Yes this would reduce range but a couple of battery charger stations would more than make up for this issue. Robot does not need to run a marathon, just a series of 5k sprints. This is how every mechanic keeps their power tools always powered up.

[@skepticalmechanic]

Would be great for car repossessions!

[@marcusoutdoors4999]

Interesting to see the arm swing which seems very natural.

[@curtisyoung7107]

Totally enjoy these bot videos and analysis. Because be mass copying continues to be an ongoing issue it makes sense to establish your credentials to back your patents and eliminate the need to redesign when conflicting patents crop up taking credit for your work. A much bigger benefit is to spread the knowledge to a much wider audience to advance the field and accelerate acceptance better ways to get things done 😊

[@yacahumax1431]

AMAZING.

[@pdloder]

Each step isn't one foot (that would only bring the hind foot up to level with the front foot) it's two feet - because the heel of the back foot, moves forward past the heel of the front foot and lands somewhere near the toe of the front foot - that's two feet. So it's gotta be twice as fast as Scott's suggests.

[@hhal9000]

Great that you worked out they must be using motion-capture to train the walking .

[@MudGuardian]

No head movements here, i would assume end to end

[@FrunkensteinVonZipperneck]

Necessity? Multiple cameras obviate need for head degrees of freedom.

[@MudGuardian]

@@FrunkensteinVonZipperneck if the purpose of this video is that it is improving at walking then could be trained on simple footage without the camera panning, therefore no need to move the head. I'm well aware of the cameras, but if trained on footage to mimic head movements while walking then it would be doing that too. There has to be some objective there

[@coreycoddington8132]

Yes the stride still seems segmented, they're not allowing the bot to go into a full Dynamic maneuver yet. Slowly piece by piece I believe they'll add Dynamics into the flow .. segmentation will slowly Melt Away. But it will take time

[@coreycoddington8132]

Let me clarify... to say that it's not moving dynamically at all is not true. What I mean to say is it's limited in its Dynamics

[@ArizVern]

BEFORE VERSION 3 COMES OUT, TAKE SHIELDS OFF VERSION 2. SHIELDS ON WHEN VERSION 3 COMES OUT.

[@angstyrossini]

[@FrunkensteinVonZipperneck]

[@carl-Sp]

I think the mocap allows them to calibrate where bot thinks its limbs are in x,y,z against where they really are. One function of perhaps multiple.

[@andrewradford3953]

Even cheap small cordless power tools use three phase motors. DC to 3 phase AC inverters are tiny, the motors produce more torque for a much smaller lighter unit. Pretty sure Optimus is using AC for motive power.

[@jaynorthwoods]

From experience at charging and cooling large lipos for DJI s1000 the cooling is probably needed more for the processor and that’s probably it. Charger itself has a fan but battery doesn’t really need it.

[@jhunt5578]

My exact thoughts seeing the video. Was I thought Elon complained about people copying from the videos and now hes showing Optimus uncovered

[@oznerriznick2474]

That's awsome! How about a more youthful gait. Lengthen the stride. Straighten the knee more. It would be more natural. Still...amazing work👍!

[@ufo2go]

Thats where its going Oz.👍

[@garyswift9347]

the box on the back looks like an antenna. I'd like to see it push a cart. In maintenance, we use repair tags like that yellow tag, and we also mark non-standard parts, such as experimenting with a new type or brand of part, with tags like that.

[@ThomasBussmann]

The man in the background with the reddish remote control looks like young Elon.

[@murta1979]

I wonder if they use motion capture to train Optimus to walk. You can see the small grey balls all over Optimus in the pictures, I think those are used to track the frame. Do the same on a human at first and then train the Optimus NN on the human motion.

Swinging arms in human locomotion is a way of balancing the human body. If Optimus had a sophisticated movement such as this, it would not seem so awkward.

[@n2l2l]

@@Tinman_56 small test steps. When I saw this machine doing squats with balancing fingers... well, we would be veeery surprised by its moving abilities in a year... and it will grow exponentially. Especially if they also can for example feed new skills artificially, not only video-in, like in Matrix for example. I saw nVidia artificial bots learned almost black-belt fighting techniques that human learn in 10 years - in few hours of training....

[@zagabog]

FSD computer in optimus is like in the cars, operating with higher inference capability for size and power consumption, hence no back pack.

[@murta1979]

I would guess Optimus uses brushless DC motors (BLDC), similar to what is used in RC-cars/planes now days. The controllers for those motors can be made pretty small with today´s power electronics. The controller would in that case be integrated on to the motor-assembly probably including a small microcontroller so that you only have to route a ethernet cable and a DC-bus to each motor. They could also use the same ethernet-loop tech as in the Cybertruck.

[@ByronBennett]

The block on the back is a restraining bolt

[@minifamily3]

At some point can you explain why Optimus does not have a human walking stride i.e. the knee remains flexed when it strides forward which limits the length of the stride and the walking speed.

[@tonyduncan9852]

Beautiful, but I bet it can't survive falling in a swimming pool, or even being sprayed by a classic fire extinguisher. Yet. 😎

[@rayseyfarth]

I wonder if they could use a flexible heel with some springiness like the flexible toe. When walking the human heel hits the ground well before the toes. Optimus is not varying the angle of the foot while walking. I think faster walking would be easier with some rebound from the heel and the toes. (I know it doesn't have toes but I wish to be polite to my future robot overlords.)

[@karla6999]

Hey friends, the Teslas of course have converters to convert DC to 3phase AC for the drive motors! Optimus motors may be DC, but most likely they are AC too at least for the legs, so also converters needed too, tiny ones though. It‘s an impressive demonstration what Tesla has achieved. Walking upright on two legs is a quite complicated task.

[@deadzen]

And learning that end to end neural is amazing!

[@jimwithheld7217]

I expect the motors are normal "3-phase brushless", just like in your battery drill, a toy drone, oh - and in your Tesla car. Basically you need DC power, a handful of power MOSFETS and the control signals. If you count their cars, Telsa have made many millons of them and appears they know how to make them work well.

[@garyrooksby]

[@cyrilvankeirsbelk7299]

Optimus is 5' 8" tall, so that means the feet are probably around 9 inches in length or more. This makes the step at least 18" in length, front "toe" goes from behind the heel of the other foot to at least a foot length in front of the other foot. So it's at least 50% faster than they estimated. Get better at estimating!

[@JonnyWaldes]

The hardware is nothing special. Look up Xpeng robot.

[@andyonions7864]

There's an assumption that Teslabot is working at 48V and you'd assume that all motors would therefore be 48V. But motors will be driven at less than 100% most of the time using PWM at say 50kHz. As soon as you go there, then you can actually drive any voltage motor up to 48V. It wouldn't bother me having mixed motor voltages in my own designs. PWM will efficiently use the power available even for say a 6V motor,

[@Tinman_56]

AC to DC converters are not inverters. Correctly identified they are rectifiers. Inverters convert DC to AC, which is very different in operation.

@user-tg9xk9sy9k in its simplest form, a converter is the generic name for anything or any device that can change one thing into another, such as converting audio to digital signals, such as the old TV RF transmission to Digital TV signals, sunlight into electricity and more. It is true that an inverter and a rectifier, or even a charger, do convert, in this case, different states of electricity to other forms, but DKIA and Scott are using the term "inverter" incorrectly as used here in their explanations of charging or powering the Bot in this video. 🙃
