Those are the same people that say that China is 30 years behind in chip manufacturing.
I don't know if you're aware but robots and chips are different things that require different expertise.
Very exciting times to live through.
Some people on X are saying they're "just" cloning/copying "puppet" human movements. I know very little about robotics, but given these appear totally free-standing, if that was the case (I personally don't think it is), wouldn't that imply they have the same centre of gravity and weight of limbs as humans? Surely they'd have to be able to balance themselves, and copying a human's movements "exactly" wouldn't work fo…
I've worked on much less expensive, much smaller humanoid robots. These robots are certainly running through a scripted set of poses which has been extensively tested for the conditions (Humans would also be choreographed and have to hit certain marks at certain times). If you covered the stage in loose gravel or a thick carpet they'd all start falling over. The things the robots hold are almost certainly taped into…
You can clearly see that the robots change their grip of their sword, so it cannot be taped to their hands.
Just submitted this as well. This is remarkable. Boston Dynamics has some catchup to do.
Boston dynamics is far behind plus the robots are so cheap , even their dog is cheaper than BD. I dont think their humanoid can even catch up to this price. I am sure US Army and for the chinese counterpart Chinese army will be their biggest customers. But i wonder how will this workout in situations like Plane hijack, fire fighting and other such places where human lives cant be risked to save more human lives. (Ple…
I personally agree with the rest, recommend you remove that last bit about downvoting and sneering if you can still edit
Last time I had to implement a typed programming language, it was for short programs only. So for typing I just converted the program into a large set of constraints and throw z4 at it, asking to optimize for smallest possible types. If z4 could find types for every expressions in less than a few seconds then it was well typed. You had to use a few trick for larger programs, but basically it managed to type any real…
Any information what battery life these things have? Would a human be able to outrun them given the need?
1) Cool, but when are they actually going to drive my car for me? 2) Any semblance of American technological superiority is pure fantasy at this point. The only area where Americans are truly "advanced" is in selling overpriced SaaS products. There are dozens of Chinese startups with robots just like this—as seen at CES—yet Boston Dynamics is still treated like it’s some untouchable, DARPA-level tech. 3) A lot of thi…
It’s clear to me that the smartest thing China ever did was to limit speculation in the markets. So many human capital in America is wasted pumping up valuations instead of actually building stuff Every Jane Street hire could be building robots, but instead, they’re trading options and crypto and heck, even market making for prediction markets now
Crypto is a good example of how the equilibria is hard to maintain, and if the last cycle saw many interesting new products come to life, they all got crushed by ruthless profit-taking from early investors and team members.

To be fair to BD, Atlas can lift 50 kg and a Unitree G1 can lift about 2 kg. An Atlas could literally pick up and throw a G1. They are very different robots with very different goals, so it should be no surprise that the G1 appears much more agile.
Isn’t it easier to make an agile robot big than to make a big robot agile?
Human individual fingers can withstand internal loads of hundreds of newtons, (possibly a thousand for brief periods if you're a star rock-climber), while at the same being capable of tasks such as writing, which require high speeds and (sub-)millimeter precision, while also enjoying 4 degrees of freedom (5 for the thumb), and they're stuffed full of sensory organs to boot. Oh and they're also self-healing, so taking some damage during use is no problem and they will actually adapt to the task they're used for over time. Everything we can make compared to this is laughably primitive.
If you make an agile robot big, it now weighs more, which means its joints now need to handle greater loads, which makes it necessary to make them much bulkier and heavier.
A lot of this is just inherent limitations of electric motors and having to convert rotational energy. This gets heavy fast.
Decent synthetic electrically-driven muscle fibers would go a long way.

Not a fan of bipedal platforms or 50kg of servos for a number of reasons.
Best regards. =3
Well, that is obviously another overcapacity issue, this time for robotics. In the last 10 weeks, there were - Unitree's army of robots https://www.youtube.com/watch?v=w4IOJH9Akhg Robotera sword dancing robots https://www.youtube.com/watch?v=9Ti9Mi8rbIQ AGIbot's flying kicks https://www.youtube.com/watch?v=QXnXdh6IEkA LimX's Tron2 robot https://www.youtube.com/watch?v=Ut3QFPr7hyo one interesting observation is that n…

there was this Chinese company named Baofeng that built a stupid media player by "re-using" open source FFmpeg code, it managed to get itself publicly listed, then had its valuation went up like 50x for doing nothing other being accused for stealing FFmpeg code.
there were lots of discussions at that time how that happened and why the same level of speculation didn't happen on other public tech companies listed on Chinese market, the consensus was pretty sad - tech companies suitable for speculation are listed in the US by default, those listed on Chinese markets are 2nd tier or 3rd tier to start with, they don't offer any meaningful room for speculation.
