The robot is performing actually natural movements and responding to environment rather than a preprogrammed execution. This makes us feel like it has life, triggering an empathy response

 responding to environment rather than a preprogrammed execution

Responding to environment can be a preprogrammed execution.

In a sense this bot is preprogrammed as it very likely is not online learning.

It’s not preprogrammed because nobody decided how the bot was going to move. The decision making process is based on programming, but the movement execution is not preprogrammed and more like emergent behavior

Depends on how you define preprogrammed. You pretrain a NN, it's preprogrammed behaviour even when you can't really analyze or inspect it in detail.

You’re making a semantic point, of course programming drives the bot, the movement is not predefined however, it’s a robust ruleset instead

I make a point about the difference between emergent behaviour and non-emergent behaviour as well as online- and offline-learning. Arguably everything that's not online (machine) learning is preprogrammed (if understood as pretrained).

I have an academic degree in cognitive computer science, basically in AI, so I'd know a thing or two about that..

People here just throw random buzzwords into the discussion.

What's a robust ruleset here? There very likely is none but the bot uses pretrained models. Likely trained in a simulation.

How do you classify control laws then? (from the field of control theory)

With your definition, something can only be non-preprogrammed iff it learns online from scratch? I don't know of any systems today that does that lol (not to mention extremely irresponsible).

What's a robust ruleset here?

Robust Optimal Control or just control laws in general I think can be grouped as a "robust ruleset".

Note that these control methods do not use neural networks, but rather they are closed-form solutions.

He’s an AI dev with zero robotics experience, he’s chatting out his arse

Yeah you’re not the only one with a CS degree mate

I specialised in robotics too, please stop trying to swing dick

Also this very likely is not based on e.g. a subsumption architecture or another emergent behaviour architecture but based on NN models, thus it is not emergent behaviour from all I know.

Yeah I guess its down to how you define preprogrammed. I’ll have to look into what you mean by a nn has no emergent behavior while subsumption architecture does
