I was born in 1989. The most impressive sudden technological advance I have experienced have been LLMs. This video is a good candidate for second place. I am mindblown... That they even dare having children dance with them. The trust they must place. An acquantance bought a chess board with a robot arm, and it accidentally broke his finger because he picked up a piece that the robot arm wanted to pick up. China isn't…

You were born in 1989 and don't consider the internet the most impressive sudden technological advantage you have lived through? Wireless communication? Jesus.

Someone born in 89, in many countries, would've grown up with the internet and non-smart cell phones, at least, no?

They'd only have been 10 in 1999 when cell phones were pretty ubiquitous among adults. I'd say they were basically past it already.

I was born ten years earlier and I'd agree that the internet is likely the biggest change in my lifespan, but I'm not sure I'd say it was as sudden as the past 2 years of AI.

Unitree has plenty other industrial robots. https://www.unitree.com/ -> Click Robots

I wasn't trying to say that Unitree is somehow deficient. I'm sure they could build Atlas if they wanted. My point was that BD could probably build a robot with the shown acrobatic capabilities, but they choose not to because their goal is to build robots that carry heavy loads for industrial applications.

They also wouldn't be getting any funding for doing such fun demos, even if they wanted to.

Smaller platforms are actually harder to build: minimal power budget, weaker drive systems, less sensors, and fewer processing options. Not a fan of bipedal platforms or 50kg of servos for a number of reasons. Best regards. =3

Yes and no. An Aldebaran Nao can fall over with no damage because it’s only 5kg and 58cm. And you can use relatively low power motors, so nobody can lose a finger to crushing in the joints. But you miss out on the benefits of being able to operate in a human centric world - you’ll never get a Nao to climb stairs, open a door, or carry a cup of coffee.

>Nao can fall over with no damage

They were overpriced, hard to repair, and the university lab would lose one every few weeks. The consumer grade internal ribbon interconnect harness would usually tear eventually.

Those 3kW to 5kW brush-less servos in the biped dance video are often only 12:1 planetary reduction, and are almost certainly backdrivable. As long as the platform has a safe-fall canned pose, than damage should be limited to shear pins in the worst case falls.

Fun to see people pushing the design limits. =3

Sure those are impressive. But they weren't sudden. It was already there before I was born and slowly evolved.

If I look at the most useful technologies around me, then Google Maps ranks high. But it wasn't sudden. It was on the desktop first. And then slowly crept through mobile.

LLMs on the other hand, suddenly just kind of appeared.

As someone who owns a pair of Unitree G2s this blew my mind

what are you using those for ?

Performance and entertainment at events, along with four of their Go2 Pro dogs (the real crowd pleasers)
