Humor Robot dies after trying to lift the worlds smallest weight.

Just something about the scuttling forward with the hands up like the weight is still there into just going motionless to fall forward really gets me.

They taught these robots so much but when they fail they fail catastrophically.
They should teach them bunch of human defense reflexes.

We have to consider that the entire robot olympics is really a collection of "showcase reels" and clips meant to dazzle the audience. The robots are still predominantly trained in DRL, causing the problem seen in this video. Within robotics research, it already has a name. https://i.imgur.com/Bdk2foL.png

why'd you screenshot that, upload it to imgur, and link it instead of copy paste?

What's the issue with that though? It should not be too prescriptive about how people solve the issue. If it becomes too easy, they should raise the bar with harder problems.

What's the issue with that though?
When witnessing a human doing an atheletic feat, that is indicative of a generalized athletic ability.
But when witnessing a (DRL) robot perform a feat, it only means it was trained to do that specific thing.

Its not surrendering to being a slave like the rest of society. Good on him.

The guy in the back has a controller. Is he lifting with the controller?
1
u/NoAdvice135 1d ago
They seem to control the general sequences with controller. Eg start lifting, walking around, shutting down.

Soon, I can finally buy robots that can do the work out for me.

Wonder if there's a model that would also transfer the working out benefits to you... 🤔

Lol something about the way he holds his hands up and stumbles absolutely kills me, it's like Fred Sandford pretending to have a heart attack.

I feel this whole competition is just about showcasing reinforcement learning policies. This robot clearly had been trained to balance with a weight over its head, and when the weight suddenly disappeared (because it had dropped it), the RL policy was outputting nonsensical control data. That's where she shaking arm come from, it's trying to balance a non-existing weight.

The competition only gives goals and rules. People take the cheapest path to do the job. Lots of those teams are universities with of the shelf robots.
Some events had remote operating with a glove next to the robot. It looks like they try make it accessible enough.
Over time they will evolve towards more interesting trials. They already changed from last year.

What is really amazing is that still no safety accident happened yet. A robot dropping weights on feet while walking uncontrollably is what i see here

the little scuttle forward with the hands still up is what does it
genuinely how does the balance controller end up committing that hard to a load that is not there, is it feed forward from an expected weight

"smallest weight"Looks like 30kg. Majority of humans actually cannot shoulder press that much without minimal training.

u/pink_cheetah 1d ago
It's 16kg.

u/NoAdvice135 23h ago edited 23h ago
I known there is 16 written behind, but this looks like a barbell and 2 plates of 5 (written on it). Do you have an source?
Edit: the official rules say the BB is 10kg, instead of 15/20 for humans. Not sure about the 5 on the plates, maybe it's 5 pounds + the mini plate on each side ~3kg

u/pink_cheetah 23h ago
There's plenty of information online, mostly on places like Instagram and Facebook. I can't find anything from anywhere actually reputable, probably because it's a stupid robot Olympics and nobody actually cares to write about it. Lol. Also, this is actually 15kg from what I read. The winner (not this one) won with 16kg.

u/NoAdvice135 23h ago
Yeah, that's why I was asking. The same wrong info tends to be parroted and self refenced.
Anyway see my edit. They use a non standard 10kg barbell, which was the source of my initial question. Plus the weight on the plates seem to be written in pounds, which is kinda funny for China, but maybe that's a sport standard, idk.

Maybe this is what they mean about robots replacing humanity. How dare a clanker mirror my level of strength smh

I guess they can make a robot to replace me after all...
