If the human-robot war is waged on a perfectly flat surface, we are fucked!

#921) 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…
#4 is the biggest problem, by an overwhelmingly wide margin. Solve that and everything else fixes itself more or less instantly. Everything is now about money and extracting every single penny possible, instead of about actually achieving things. Even most 'entrepreneurs' are now just starting businesses primarily with the goal of selling them. Everything is broken, because of the pursuit of money became the goal, fu…
The micro-financialization or wallstreet-ification of everything is a succinct way I try to describe it to normies

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…
> The things the robots hold are almost certainly taped into their hands. You can clearly see that the robots change their grip of their sword, so it cannot be taped to their hands.
Probably a compliant magnetic coupling, as even simple force-sensing mechanical hands cost too much to practice back-flips. =3

#94battery life measured in a handful of minutes too :-P
3 hours, so if 180m is a handful, but I don't agree, my micro-drone is a handful at 3-4m of flight

It looks like the difference between the Boston Dynamics robots 2016 vs 2021 The Spot dog (which inspired the Black Mirror "Metalhead" episode) in 2016 https://www.youtube.com/watch?v=tf7IEVTDjng Atlas doing backflips in 2021 https://www.youtube.com/watch?v=FByY3tSx2Ak So 5 years of progress within a year.
spot dog is hydraulically powered junk, unitree is motor driven from day one. Boston Dynamics was forced to switch to a motor driven architecture after it is proven by unitree. Boston Dynamics is the follower here.
why is hydraulics junk?

China installed 295,000 industrial robots last year, more than the rest of the world combined, and has over 2M deployed total. China makes its own robots (57% indigenous) and its rate of robot deployment continues to grow year to year. Meanwhile, the US installed 34,200, a decrease on the previous year, and virtually all of those were imported. https://ifr.org/ifr-press-releases/news/global-robot-demand-...
Do these dance? And what was the % of industrial capacity non automated over this percentage increase, because of course an industrializing country will have more manual processes to automate.
You asserted that American research is "financed by outcome potential not for grandstanding". But China is not just building dancing robots, they're also installing tons of industrial robots whose sole purpose is making money right now.

#98Some 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…
As someone who owns a pair of Unitree G2s this blew my mind
what are you using those for ?

I look after one at a University that gets used for teaching & outreach & there's definitely no hydraulics on the thing.

#100Last 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…
