All of the examples in videos are cherry picked. Go ask anyone working on humanoid robots today, almost everything you see here, if repeated 10 times, will enter failure mode because the happy path is so narrow. There should really be benchmarks where you invite robots from different companies, ask them beforehand about their capabilities, and then create an environment that is within those capabilities but was not used in the training data, and you will see the real failure rate. These things are not ready for anything besides tech demos currently. Most of the training is done in simulations that approximate physics, and the rest is done manually by humans using joysticks (almost everything they do with hands). Failure rates are staggering.

The last example they show (pick up package from pile, put it label-down on conveyor, repeat) seems to be the most realistic. They even have an uncut video of their previous model doing that for an hour on twitter [1].

I'm not sure that task needs a humanoid robot, but the ability to grab and manipulate all those packages and recover from failures is pretty good

An industrial robot arm with air powered suction cups would do the trick... https://bostondynamics.com/products/stretch/ ...

... So the task they work best at is the task there is already cheaper better robots specialized for.

I feel like we're entering the era of general and inefficient solutions to problems.

Like LLMs being used to pick values out of JSON objects when jq would do the job 1000x more efficiently.

This is what this whole field feels like right now. Let's spend lots of time and energy to create a humanoid robot to do the things humans already decided humans were inefficient at and solved with specialised tools.

Like people saying "oh it can wash my dishes for me". Well, I haven't washed dishes in years, there's a thing called a dishwasher which does one thing and does it well.

"Oh it can do the vacuuming". We have robot vacuums which already do that.

There were plenty of digital circuit engineers back in the 90s that said microprocessors were general and inefficient solutions to problems.

And if you needed it programmable, well an FPGA was still almost as general and far more efficient than a microprocessor.

Guess what won.

As a hardware engineer I hear this a lot from software/electrical folks.

It's Moore's law that largely drove what you describe.

Moore's law only applies to semiconductors.

Gears, motors and copper wire are not going to get 10x faster/cheaper every 18 months or whatever.

10 years from now gears will cost more, they will cost what they cost now plus inflation.

I've literally heard super smart YC founders say they just assume some sort of "Moore's law for hardware" will magicallyake their idea workable next year.

Computing power gets, and will continue to get, cheaper every day. Hardware, gears, nuts, bolts, doesnt.

Think about cars. Their manufacturers work really hard on efficient (cost and performance). And what people do with them is a very different story. It could see the same happening with robots.

The nuts and bolts won't change much but the software/compute controlling the thing likely will.

It is not the gears, motors and copper wire that are bottlenecking robots. It is the software and computing. We can already build a robot hand that is faster, stronger, more dexterous, etc. than a human hand. What we can't do right now is make the software to perceive the world around it and utilize the hand to interact with it at human levels. That is something that needs computing power and effective software. Those are things that get, and will continue to get, cheaper every day.

Can you attach it to a humanoid body that isn't wired?

It is those things that are bottlenecking the price of robots.

The price of something tends towards the marginal cost, and the marginal cost of software is close to $0. Robots cost a lot more than that (what's the price of this robot?).

Edit: In fact Figure 03 imply marginal costs matter:

  Mass manufacturing: Figure 03 was engineered from the ground-up for high-volume manufacturing

Yes, but the two (software and hardware) scale very differently.

Once software is "done" (we all know software is never done) you can just copy it and distribute it. It is negligiblehow much it costs to do so.

Once hardware is done you have to manufacture each and every piece of hardware with the same care, detail and reliability as the first one. You can't just click copy.

Often times you have to completely redesign the product to go from low volume high cost manufacturing to high volume low cost. A hand made McLaren is very different than an F-150.

The two simply scale differently, by nature of their beasts.

But the nuts and Bolts need to be paid for and manufactured for each robot. The software needs to be done once and then they can just click copy.

I dont follow
11. aeternum ◴[] No.45540730{4}[source]
China has shown that they don't scale all that differently. Yes the tooling is hard to build but after that you hit go and the factory makes the copies for you.

It's not quite startrek replicator but much closer to that than the US view of manufacturing where you have your union guy sitting in front of the machine to pull the lever.

This isn't true. They've showed that slave (or nearly) labor is cheap or even free.
