Can anyone that works on this technology provide an honest assessment of where this technology actually stands? How much instrumentation is actually required, what the interaction quality is, how much trouble do humanoids have with in the wild daily tasks like turning doorknobs, recovering from falls, avoiding knocking into things, etc.

I work in this field, and I wrote my bachelor's thesis here, not with humanoids but with VLAs (think chatgpt connected to a robot arm)

It's certainly not there yet for anything practical, there's also certain bits and structures that don't have accurate names during construction, and it is important to keep that in mind - so a robot is unlikely to understand what it means to say "put the left bit of this box onto this right bit" due to ambiguity, a human would understand that

Plus we have no good reliable accuracy testing data in most cases (most tests occur on a few demos, but that isn't a good representation of how must things work), popular benchmarks, such as libero have been saturated, and nearly everything gets 95% there, most companies and researchers have their own benchmarks here.

Plus companies lie alot, and do very dangerous things in thier videos, I.e. these robots should not be standing very close to humans, because of being dangerous.

There are also legitimate concerns of misuse of these robots that need to be accounted for, misuse does not have to be warfare, but can be as simple as confusing it while it is cutting tomatoes with a knife.

Turning doorknob is easy, and fail recovery is also being worked on, but we don't have reliable statistics anywhere on that. The hard part is on practical things, as in when placing bricks or attaching a part during manufacturing it needs to ensure that it is aligning everything correctly....and that's hard, while it is impressive, it is very irresponsible to keep humanoids at home (people are irresponsible when untrained), for example, lawnmowers injure about 6400 people a year...and that is not an everything machine.

Humanoids in general are...not appealing in specific, due to maintainable of joints, complexity, but robot arms in particular, expecially on wheels (check mobile aloha), are likely to be able to do tasks such as clean up in hotels, after a guest had left, or replace some cooks in restaurants (if their work is consistent)

It’s still at GPT-1 level, but GPT-2 moment feels imminent.

IMHO the real test is if any robotic startup currently selling (or planning to sell) robots as a service for homes not just use it but gets returning users from it.

I did professionally few prototypes with robots and progress is real yet very far from what the average customer would find reliably useful in menial tasks.

FWIW I do think https://rodneybrooks.com/why-todays-humanoids-wont-learn-dex... remains relevant, namely dexterity is also a hardware problem, grippers aren't hands. They even clarify "multi-finger dexterous manipulation remains challenging." and those aren't even fingers with a lot of sensors.

There is a LOT of monkey business when it comes to robotics industry, a lot of demos you see are well crafted for that specific demo, a lot of times there’s even actual fraud “like claiming it’s an autonomous but it was actually teleoperated during the demo”, a lot robots that make most hypes are practically useless (dog robots or qugv for example) no matter how they try to create a usecase, when it comes to practicality, most fail. Robotics as an industry is niche (not to be confused with cobotics) the only exception is drones which is something I said in a workshop back in 2020 that drones are the only potential and will dominate if we solved the endurance issue, which is also why they immediately got weaponized because humans are usually evil and will utilize useful stuff in bad things.

Humanoids are far from being remotely useful in real life scenarios, yet.

Fun fact: most (if not all) qugv can’t go reverse on a stairway.
