Support Scott so he can buy the headphones (and mic) just like Brian uses.

[@HalfDead1957]

No kidding, this is tiring concentrating on what he is saying and trying to decipher it.

[@KelliSloan-r2b]

Thank you Brian and Dr Scott for an enlightening discussion. Grateful to both of you for the fantastic conversation. Looking forward to many future conversations

[@FutureAzA]

He's such an asset to this community, but you are too, and I appreciate you both.

[@adamrak7560]

Under 50V you can comfortably touch DC voltage with dry hands without any zapping. 100V is the danger threshold, where you can be in serious danger in you touch it in some cases. Generally above 60V DC, you have to handle the voltage as dangerous high voltage, because if somebody licks it and closes the circuit in an unfortunate way it could be really dangerous. But if you touch 60V with dry hands you likely won't even feel it, depending on your skin thickness and tolerance. With AC, 50V is the safety limit. If you touch 50V AC you will feel it. The robot has AC in its BLDC motors, so it is a good idea to not exceed that during operation.

Dr Walter, your microphone needs to be a lot louder on every podcast you attend. I would like to hear what you're saying ❤

[@markeggleton2981]

Another great video Brian, keep up the good work!

[@LJ-jq8og]

Dr. Scott 💪❤

[@Rob_Womack]

Thanks guys!

[@hanswitvliet8188]

Great video: It gives you something to think about for a long time after the video ended. Well done!

[@davidhuber6251]

I don't think most people realize how using humans, to train robots with very similar degrees of freedom, using a neural net, is such a game changer. It's hard to tell how powerful the neural nets *really* are from just press releases, but the potential is amazing.

[@olebloom1641]

A great discussion. Amazing how little movements can derail an action.

[@fredt7518]

Could Scott get a better microphone ...?

[@FutureAzA]

He has all that in his office. I don't expect anyone to carry their gear around with them to make my life easier.

[@Thomasvanblijswijk]

Too bad his audio is so bad!

[@luismontelongo4148]

You always have captions ​@@Thomasvanblijswijk

[@markwindsor914]

Finger nails? You need them to pick a coin off a table.

Well thought out questions Brian! You know Dr. Walters well enough to know what you can expect to elicit out of him. All helpful and interesting bits to help us understand Tesla's competitive advantages, helping us with our convictions. You brought up the mulch walking balance catch. Amazing to me it was able to do that without any vision. Pure gyro momentum correction similar to SpaceX falcon rocket vector corrections. More great content!

[@gcauldwell]

Whenever I see complicated solutions, I try to calculate how long it would take me to come up with it on my own. Always the same answer: mind-boggling.

[@mikecranapple8878]

You guys rock!

[@hanswitvliet8188]

Counting the change, blindly, in your pocket, is something already hard for many humans. That would be a nice test for testing robots performance!

[@r.a.monigold9789]

Doctor. Doctor. Give me the news. Info that only Doc Scott has - info we can use! Brian, thanks again for questions so insightful they generate answers that are useful. Thank you BOTH for sharing ! ! ! (shout out to Robert Palmer's great song)

[@garyrooksby]

Scott is fantastic.

[@doctormix71]

About a year ago, while taking a nice walk in cool weather, I reached up to tie my hoodie tighter. Then I wondered, how long will it be until the geniuses at Tesla get Optimus to do this without looking at its fingers?🤔🤩 Recently I’ve also been wondering about wear and tear on the hands and how they will replace the soft bits and sensors in the fingers?🤔 Great discussion fellas!🙏🏼😁🖖🏼

[@YACINESEBTI]

Walter needs a better mic, the sound is muffled which might also be caused by low bitrate. 🎤🔺🤐

[@jamesdubben3687]

Yeah Scott

[@MrEd2291]

Great presentation!

[@karlsimmons8992]

One thing I often want to know is how strong is Optimus and what are they working on to improve this?

[@machoopichoo2]

Interesting tidbit around pain. It was standard thinking for many years that itching was a mild form of pain through the regular nervous system. However, itching has its own dedicated sensory system. This makes a lot of sense, as itching is very closely associated with parasitic infections. Should Optimus be able to scratch its own back or just ask for help from another bot?

[@АгронДепартье]

Can't hear the doctor...

[@machoopichoo2]

It might be a little herky-jerky but could the mechanism in a Rubik's cube be an inspiration for a shoulder joint in a bot?

[@mikecranapple8878]

Tesla Optimus will make other robots look like robots, lol.

[@davidhuber6251]

So incredibly satisfying deleting spambot comments that I get up early to do it. I wonder if they will quit spamming if we continue to thwart their skullduggery.

[@FutureAzA]

I doubt it. They'd have to see returns less than it costs to run the bots, and bots run practically for free. There are less sophisticated bots that use the same text over and over, and I've set up filters for it. Doesn't stop them even though their comments never, ever see the light of day.

[@penderic3415]

Drawing tablets have touch screens with hi resolution pressure point detection. (used for digital brush stroke creation). Can it be made in a flexible skin? Yet?

[@FutureAzA]

Interesting.

[@machoopichoo2]

I am really surprised the bot will be 52V and not 48V because 52V is getting into the danger zone for electrocuting people, although we know current is the most important factor in the dangerousness of electricity.

[@machoopichoo2]

That and Tesla has already started using 48V, as we all know.

[@FutureAzA]

It IS 48v. The deeper explanation might have been in part 1.

[@machoopichoo2]

@ I think the good Dr. indicated it is nominally 52V, which indicates it will mostly run around 52V, with some variations in voltage under load. More important though is the current, which is the biggest part of danger to humans.

[@luismontelongo4148]

It will only tickle a bit in the worst case

[@machoopichoo2]

@ Supposedly anything over 50v is dangerous, but obviously it's not nearly as bad as 120v or 220v. Again, current is the most potentially dangerous.

[@greatcondor8678]

Is Optimus double jointed?

[@FutureAzA]

A great question. I don't think so, but maybe it should be.

[@mikecranapple8878]

I'm buying Tesla stock in case universal income doesn't happen.

[@FutureAzA]

That's an interesting hedge.

[@machoopichoo2]

It would be cool if a simulated Optimus could be dropped into a first person shooter game. Probably wouldn't be that good at it, but better than an NPC. Hey, maybe Grand Theft Auto could be fun.

[@doug3691]

So many makers of Robots, and LLM's . . . and Tesla is currently under $400. I hope this latest thing gets Elon more focused on Tesla stuff, as Grok seems to have some serious competition.

[@royh6526]

" Grok seems to have some serious competition." Deep Seek is a major step forward for AI, and the Chinese deserve full credit for that. But they were nice enough to place their discovery as open source, free for all to copy. XAi, and all the other AI companies will quickly include this capability into their system.

[@OuterSpaceDogs]

Comment of the Year: Is havin a Tesla Boy Robot? Like a "StarBoy" an Optimus children sized, becomes the toy of the child, films and teaches and does someof the childs chores, grows up with the child... Then when you child becomes taller, Order Longer legs from Tesla. Gone are the days whe you buy a bunch of tys that will just be thrown away. StarBoy wll have longer legs,arms as the owner becomes 18 years old. And when the owner is 20s the Cyber Bot "StarBoy" is the dj of the Owner'S wedding. "starboy, could you play the song when my wife now first met at the playground with her own StarGirlBot?" Starboy says, "sure Dave!" Or... The tesla teen bot just kills the human and he takes over the persona and the boys character while the parents are In disgust because tesla bot is covered in blood .

[@LJ-jq8og]

Robots Just like Marriage.. Looked good initially but then went CRAZY 🤪... PROFOUND... 🤣

[@1001Balance]

If their AI is developed the same way as openAI, the Chinese just beat them to it. Self-reinforement learning seem the way forward. Check the British company Wayve using a similar approach for FSD. Will Tesla push through or change strategy?

[@FutureAzA]

I know it may not be a popular opinion, but I'm of the opinion it may just be too early to know what the best (and maybe only?) approaches will be. If a company isn't prepared to pivot, they may never get there at all. We've seen Tesla do a major pivot a few times on FSD, so I'm hopeful they're able to recognize when they're on the wrong path.

[@1001Balance]

@@FutureAzA I agree that they are more 'flexible' and have less ego (except for the majority stakeholder) than other companies. It may be a setback this year, but will pay off more in the future. I would be interested to know more about Wayve. They are still startup level but secured a billion in investment. They use a very different approach.

[@OuterSpaceDogs]

The future owner of a Tesla Bot could have asmal bot toy, and they would train the bot by shaping the toy.... Just like a voodoo doll

[@jespado]

Apologies, but I’ve decided to unsubscribe from any channel covering topics related to companies run by Elon Musk, as I can no longer support content associated with his unacceptable behavior.

[@FutureAzA]

It isn't an airport. You don't have to announce your departure.

[@greatcondor8678]

Good. Get lost.

[@robotekk]

I love Scott but you gotta have a rule of no phones! I can’t understand a word he’s saying. It’s not acceptable in 2025 to not be using a USB mic.

[@FutureAzA]

He's not a full-time KZbinr, so if we set that kind of requirement, we don't get to hear from him until his trip to Zurich is complete.

[@williampisano7573]

Lol 😂 Microsoft/apple etc… all have been working on robots 🤖 for like 20 years now but back in early 2000’s tech was not that good but there are also companies producing robots 🤖 for $250,000 lol 😂 so even if tesla mass produced the robot they would cost 100K lol 😂 50K lol 😂 only people that can afford them is rich 🤑 or companies also companies are already buy the robots 🤖 right now and tesla has not sold one ☝️ lol 😂 tesla is falling behind

[@williampisano7573]

Amazon employees robots 🤖 right now

[@FutureAzA]

You should spend some time digging into the topic. It's easy to assume you understand business, but without the ability to spot disruption, you're going to miss every big shift.

[@ronaldgarrison8478]

Screwing with the title. Automatic thumb down.

[@FutureAzA]

Nobody was watching it. 2nd worst performance of ask recent videos. Good content dies behind a bad title.

[@ronaldgarrison8478]

@@FutureAzA Do you even realize the confusion this creates when the title is changed? There's a simple way to avoid the problem. Use an episode number for each video. Many channels do this. Then you can change the title, and a viewer can just search on the ep #.

[@hanswitvliet8188]

Counting the change, blindly, in your pocket, is something already hard for many humans. That would be a nice test for testing robots performance!
