- WOW! Optimus, Tesla's humanoid robot, is here, in the flesh! As we saw during AI Day 2022, Teslabot (or Optimus) is already a walking, useful bot, and a lot of that comes down to the amazing hardware choices that Tesla has made in their design of the first two prototypes!

I was awake during the night here in Finland and was watching the stream, it was cool and I was looking for you John in the crowd ;)
Retired electronic engineer, wish I was 20 years younger, would try to get a job at Tesla.
Where they let engineers do engineering, unlike where I worked it was far more important that my lab bench garbage can was kept inside the yellow lines on the floor.
Solved that problem by attaching a pice a plastic to the bottom of the garbage can with yellow lines on it, therefore the can was always within its yellow lines.
That is definitely an engineering solution. Love it.
Creativity at work.. 🙂.
Elon would laugh at this too, I bet 🤣
Oh I agree! The misadventures by Boeing began 15 years ago when the MBA’s moved HQ from Seattle to Chicago. Now they’re moving to northern Virginia to be closer to Mother Fed
@@richardrigling4906 Didn't that happen after the management from another bankrupt Canadian aeroplane manufacturing company entered Boeing?
I forgot that company's name.
Optimus has a Texas belt buckle! Now that's awesome! 🇨🇱
I am an Orthopaedic Surgeon with an Engineering background. The human knee is a true 4 bar linkage created by the proximal and distal ends if the Anterior cruciate and Posterior cruciate ligaments. They have recreated a similar mechanism but the extensor mechanism has a dual role which lowers energy consumption. This is unlike us because the cruciate ligaments in us only create stability and guide knee kinematics but do not carry our body weight as seen in Optimus. Great talk. Thanks
This was Tesla Bot version 1... T-1 for short hand. Only 799 more versions until we get Arnold.
Thanks so much you two! This is the precursor to the Dave Lee James Douma series covering FSD that is also going to be a must watch!! I'm sure I'm not the only one who learned a lot from your talks before A. I. Day that helped us to not get lost!!
Thanks! Mr. Walter and Mr. Douma are my translators for everything that's too advanced at Tesla, for me as a layperson to comprehend and grasp the implications of what is presented. I really appreciate you being so quick with getting Mr. Walter on!
You can’t think of any implications for you’re self? You need someone to hold you’re hand? God help us.
@@Instant_Nerf How to be a douche in the comment section...
@@Instant_Nerf You can't spell simple words? God help us.
@@michelangelobuonarroti916 that’s because I speak 3 languages. Lmao
@@Instant_Nerf who?
Retired electronic engineer, wish I was 20 years younger, would try to get a job at Tesla.
Looking forward to get one of these for my home, as I get older it could help me stay independent longer.
Also once FSD is perfected for my Model Y it will also help me stay independent longer.
Someone said they built something better than Optimus in college. But this is not programmed to some predefined tasks. It’s learning how to maneuver.
In 6 months? That can pick up watering cans and water, or move boxes and parts? Doubt it kid.
@@SirHargreeves Shut up, kid.
That someone is a liar.
Super impressed with discussion and Scot running his home off solar + Powerwalls with power out after hurricane impacts.
such a cool point at the end about how Tesla already has the chips for the bot at scale production from the cars, its pretty insane how they pivot from project to project with a pre-integration or pre-synchronization of components/technology from other projects and they are in, what would seem to be, completely different fields
Just like Tesla and Spacex uses each other's strengths.
Once Teslabot is in the wild, I can't wait for the Sandy Monro teardown!
Or the Sandy bot!
Sandy is cars... he knows nothing about robots.
@@toddai2721 He's products in general. He tried doing a fridge video but it didn't perform well. So they went back to only showing cars. He's mentioned many times about planes and he did one on a medical device.
Sandy is in fact a bot and Munro's last video will be him tearing himself down.
@@toddai2721 so wrong.
I was blown away, they have designed actuators that work with existing battery technology, no one else is even close to that.
Thank God , I was waiting for your reaction
Great video - Thank you both!
AI Day was a celebration of the engineers! So happy to see how being polished was not the emphasis. It was all about what this team of engineers can accomplish in a short amount of time.. Our future is bright so long as Tesla stays on their current track. No other company has such a straightforward approach. No smoke and mirrors here. I am so happy and proud that I own stock in Tesla!
Here Here!
You two R just killing it- thanks
Love you guys talking about bot! Thanks.
Interesting!!
Many, many thanks for this very informative video. Learned so much from your analysis of the Teslabot hardware. Looking forward to your future videos of Teslabot. :)
Took y'all long enough lol love the breakdown
You guys are excellent. Thanks much for sharing your gifts.
3:20 respect to that he admitted his mistake, I meet only few professor which do it, and I hold them in high respect. Because it is human to make mistakes.
4th derivative of motion is jounce (or sometimes called snap).
we need 3d printable models of these drives. Could be such fun for education and hacking.
Thank you both for this amazing video! It is sincerely nice to see people who understand hardware and know it from the inside =)
what video?
there is video of the robot moving
it wasn't shown here
Wow they actually lit the T in the chest of the Teslabot like Ironman \o/
Awesome analysis. Looking forward to the next vid
This is amazing
Great video, thanks as always 👍
Thank you Scott!
Excellent, thank you
From a lot of commends I have seen about this (mostly in Steven's channel where he roasts them), 99.9% of what Tesla showed and explained here passed many light years away from all these poor (in brain cells) people's heads.
I was watching this live at 4am here in Greece, and when it ended (around 7:20am) I was so excited that I just couldn't sleep for the next hour.
With the rate Tesla works, I think that they will start selling these before 2025 ends. Now, I just wonder when will I be able to get one to have at home.
I don’t think people realized that Bumble Cee was not programmed by human to walk but learn to walk by AI reinforcement learning. It is also highly possible that the act of watering the plant and grabbing items and carrying boxes is also “emerged” by AI Learning.
If the battery is in the chest, then it will have a high center of gravity. This could be problematic when it needs to bend over to pick something up and the weight of the battery is hanging on the robot.
Its got a thick booty to offset it.
That is probably the reason for that heavy actuator in his butt. But where else would you place the battery? I think the torso is the only sensible place for the battery.
I guess they decided that putting the batteries in 2 balance-ball-sacks would be too much for the public.
Needs bend with its knees…
Thanks！
5:40 you can literally see one of the cameras mounted on the side... Not sure why there was confusion later on when talking about the full head / camera etc. Also interesting to note that it looks like on the back of the neck is an emergency stop button.
Scott Walker is amazing.
Thanks John Thanks Scott
Muir Woods is nice. Parking might be an issue.
If you get down to the Monterey area, you might love Point Lobos state park. It’s on the way to Big Sur.
It's truly amazing to see the beginning of a truly helping of mankind.
Great content on this video and I'm really wanting to see the video on the software side.
The fourth derivative is called jounce or snap.
Ben Katz (MIT Cheetah) is working on a fast moving linear actuator that looks pretty interesting for applications like this.
I did not expect it to walk, that was awesome. so much improvement in such a short time. and, it's also interesting to see that Tesla is not just good at AI and software, they are good at hardware too. one more thing, almost all of those engineers, are immigrants! Tesla is very good finding the best in the world. We really need to do better with our immigration policy.
Yeah.
Your entire country is built on best talents from across the world using the highly innovative environment available to contribute their best.
In the presentation the biggest thing I saw was, the lower body and how it can bend and turn.
This was mind boggling. 🤯
I’ve been to Muir Woods and Big Basin (near San Jose) and I recommend Big Basin if you have a choice. But you’ll enjoy Muir Woods too if you’ve never seen giant redwoods.
Get your parking reservations
Very informative - these breakdowns are getting more and more informative, thank you
I look forward to seeing Tesla bot's assembling Tesla bots - how long does it take to scale out production with that approach?
it would likely be slower for a long time :)
Wonder if they just make the torso and arms and the bot then finishes itself off?
@@Martin-se3ij that's what I wanted to do with my own humanoid robot build actually. It would be epic to just build the arms and it builds its own legs etc!
I frickin love that shirt!
Wow, the engineering considerations that went into the prototype were tremendous!! Laymen like me were fooled by the looks and wobbly movements :)
Take a look at atlas from boston dynamics. That is a robot!
Consider using the standard terms when reporting your observations and inferences about the range of motion of joints, i.e., flexion, extension, abduction, adduction, internal rotation and external rotation. All those ROM characteristics are measured in degrees.
Derivative of a jerk is a snap, then crackle and pop! Reference from TED talk on smooth flight in drones.
I am impressed with how excited Scott can get over a simple actuator....
No idea how they get excited about this when boston dynamics has robots that are fast, make flips, dance and practically move just like humans.
The 4. derivative of position is "jounce"
Ah yes. I remembered 'snap, crackle, pop' for the almost-always-irrelevant 5th, 6th, & 7th, but forgot what was in between.
Fourth derivative is Snap, or jounce. The fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time.
What do you think the part count will be?
Both total part count and unique part count?
Imagine Optimus came as an Ikea kit, once you have the kit of parts, what tools would it take to assemble, test and calibrate?
LOL or Lego
another thing to imagine, is that when there is a task or application where there is only need for the torso and above, they can reduce cost of deployment, and cost of batteries by replacing "hips down" with a stationary platform and permanent power connection.
Good point.
The 4th, 5th, and 6th derivatives are called snap, crackle, and pop respectively
I'm not doing two way communication but my quality on home T-Mobile is pretty good. I'm amazed how bad connections are on supposed wired lines from different content creators.
Tesla should hire Scott as a consultant. Always fun listening to you guys.
"We could spend half an hour on each slide!"
Please do! I was really getting into this. Man, I realized how little I know about the mechanical side of things especially. What are some good books or other resources on these topics?
10:05 Full head vs front only: I think what we are seeing is Optimus without the outer covering. I'm sure the body will look kind of like the original concept, but these prototypes don't have skin or coverings because they would stand in the way of development and testing.
You were right, and James Douma was wrong! It was the actual bot's hand!
Some thing I was wondering, what are the pros and cons of having toes? We use toes a lot to balance but a lot of robots have to squat a little because there feet are solid. I think a robot that could fully stand would be cool. (They have to squat so they will still have range of motion to balance back and forth)
Why they need to be human two legs form? Why not three or four legs dog first?
@@grantguy8933 You're right. More legs would be better, but they're obsessed with making it in human form, as well as cheaply as possible. 🤨
The East Indian/Indonesian posture is to squat flat-footed on the ground. No squatting on the balls of the feet, using toes.
@@kennyfordham6208 Maybe because everything around is designed for living beings with two legs.
Good torque on the ankles is important for this but always overlooked. I've also read some guys saying straight legs present a form of singularity on the algorithms, but I don't buy it, there are a couple robots out there that manage just fine.
I think they showed a "worm gear" for fingers, not tendon type actuators for all joints. 2.3KW battery will charge fast and is expected to last around 8hours (active?).
Yes, it has a worm gear, but that worm gear drives a cilinder that winds/unwinds the tendon. Simple torsion springs in the finger hinges stretch the fingers when the tendon unwinds. Just pauze the video at the close up of the hand where it shows the actuators, to have a better look.
@@MarcoNierop Thanks, was being too literal in my understanding about the joint mechanism. I'm not a mechanical engineer, but pretty good at software (hand code HTML web pages just for fun).
I'm wondering where the best AI schools are and where Scott learned AI?
Optimus VS Atlas. Looks like for now Atlas would win a 0 to 60 race and probably climb and lift better, but what about RANGE? Optimus is designed to last a day and Atlas goes for an hour. Start them walking. Which gets better range between refills?
In camshaft design we used to call the 4th derivative of position with respect to time "Jolt", but now "Snap" seems to be the popular terminology. The 5th is now referred to as "Crackle". Any guesses what the 6th is called? :-)
en.wikipedia.org/wiki/Fourth,_fifth,_and_sixth_derivatives_of_position
wow it was like watching the first part of the movie chappie
How long before household items stipulate Tesla bot compatible as a selling feature.
I want videos of stages of the bot doing robot tai chi.
The derivative after jerk is snap, followed by crackle and pop. I am required by physics law at this point to let you know that I am not, in fact, joking.
Finally some logical analysis!
Fourth, fifth, and sixth derivatives of position are snap, crackle and pop.
So what code was used to make the bot walk on and off stage? If it uses FSD computer wouldn't it have to have a destination to get to as part of the stage then be sent a return route like we do sharing our google maps from our cells? Or was it remotely moved or just programmed for 25 steps out turn left 10 turn and dance.
I think it was remote controlled.
I love how Elon is talking about how the robot is too weak to attack humans but those hands can still hold a Glock
Ideal for home defence!
My friend has a drone with a pistol mounted, I wonder if he'll trade it in for a packin' Teslabot? :)
@@D_Rogers if he doesn't add a security function where the eyes turn red I will be severely disappointed
Heads also a big weight that needs energy to counterbalance, humans use lots of energy and muscles keeping their heavy heads on😮😊
Good point. Extra servos is Extra mass away from CG.
Mr Walter pointed out several times the head is fixed and has no hinges like we have in our necks. So it will not be used to keep the robot balanced and of course will not need energy. Also the neck and spine is just one stiff bar where everthing else is mounted on.
@@MarcoNierop yes I was agreeing that bot doesn’t need a big heavy head👍 like us humans
I think that the fingers are positioned correct when it is picking up the metal parts and placing them down. if you look at how the parts are set in the jigs you could not get your fingers under the pieces as it looks like they are set flush to the individual jigs so the robot can only pick up the way it has. if the robot has been able to see and work out this then that is amazing.
It shouldn't be difficult to have two channels to insert fingers under the product. That would reduce the pinch force required to maintain enough friction. However, unlike animals, the robot can maintain a given pinch force without expending energy.
Fourth derivative of position called snap
The tesla bot in the factory stacking steel, can't put its fingers under the steel for a more sure grip, because when it places them down, it would need to drag those fingers back out from under the steel before placing it... Faster to grasp it from the sides and not clutter the underside, the steel is sitting on the underside at the origin and destination..
The student from Harvard saying what, what, what! ... is perhaps saying something about the universities?
Not necessarily, student may have been in a different silo and had no information prior to this. For example, I do not have a lot of information on details of modern abdominal surgery - I'm in the a different info silo.
@@richardrigling4906 Ok, it says something about the student then.
@13:30 the photo reminds me of the soldiers erecting the American flag at Iwo Jima
There is a slight chance that these gentlemen are getting exciterpated! :)
should put micro wheels into the hands/palms and feet/soles, so bot can subtly slide adjust footing and handling characteristics in a way no human or current bot can. Could then rebalance somewhat without even lifting feet if needed....
What we have seems to work ok
The derivative of Jerk is called Snap.
Snap crackle and pop. The next derivatives of motion.
Are they going to be using castings for the robot too?
Maybe for the outer coverings.
Don't suppose Elon will let us have the 3d print files for this...?
Seeing lots of parts that could be cast. Good implications for mass production once the design gets nailed-down.
because casting was only invented by tesla
Because they are trying to reduce parts count and cost for mass production...
What do you mean FSD cut in half? The FSD board has two identical redundant chips. The size of the box on the chest is about the size of the FSD computer. What might be missing is the ryzen board from plaid computer (guess it has too much car related stuff like a car hi-fi with amplifiers, automotive gateway, etc). They placed some control board clolse to the head? Still where does connectivity come from, it is a pci plug in card in Plaid MCU, that resides on the ryzen board.
Because there's no reason to assume Optimus has dual chips. Other than Tesla losing the ability to test code in shadow mode there wouldn't be much advantage to the extra cost, size, weight, and energy usage.
In the Tesla AI video they showed the bot PCB only having one AI chip
Just to not mess up again, do not use zoom, use Skype or for security Wire for video calls
For the tendons they said they were using boat cable.
Probably meant stainless steel cable. because than tendon cable is to small for boat use.
@@rmkep IRC sail boats use a wide variety of cable sizes of all sorts of things and yes it would be stainless steel.
Automata (2014) 😉
Reminds me of Sonny from iRobot.
Classic - drying clothes while in a power outage.
Is the robot left-handed or right-handed?
Derivatives: position, velocity, acceleration, jerk, snap, crackle, and pop. Really.
