I read that book about 7 years ago but my dad gave it to me and i know he read it years ago aswell. So its probably about 20+ years old.

The kids were from different countries. China, USA, Germany and Russia. But i think there was one more. I believe their parents were highly political figures or scientists. The kids were kidnapped from the same hotel in which they stayed in with their parents. The parents visited a meeting there.

Spoilers ahead:
The Plot twist is that they weren't on a different planet but on earth. They time travelled to a future earth which was heavily destroyed by a nuklear war i think. And the kids were the last in charge of their countries.

It's a fairly short book. I think it was around 100-200 pages.

Yes i really try to remember more. Especially names. But i can't :/
I think the main character the german kid. He definitely was a boy.
The robot spoke to them. Near the end of the book they found something odd. A modern and advanced looking door which lead them to a big underground building. In this building the plot twist was revealed.

Will definitely give your suggestion a go! Thanks :)

If not, maybe Nach dem großen Feuer?

Thank you so much

Was it ever translated into English (my rusty German says the title would be "After the Great Fire," right?)

Worldcat isn't showing any English editions.

He seems to be popular author who hasn't been translated in English that much. I found the book mentioned in the "Earth All Along" tropes page: https://tvtropes.org/pmwiki/pmwiki.ph...
