I don't think that's a western perspective, I think that's your perspective. The actual western perspective likes robots, toys, toy weapons, robotic toys, and robotic toy weapons, and all the various combinations thereof. Nerf and Transformers have been cultural staples for decades.
This isn't even the first commercial toy robot with a toy gun on it: https://www.amazon.com/Nerf-Creatures-TerraDrone-Discontinue...
Or the second: https://www.amazon.com/TerraScout-Nerf-N-Strike-Official-Rec...
Or the third: https://www.amazon.com/Unknown-782-USB-Missile-Launcher/dp/B...
Or the hundredth: https://www.amazon.com/Liberty-Imports-Control-Military-Airs...
I guess you could argue the programmable nature of this somehow sets it apart, but I don't see how.

I don't think the culture gap is where you imagine.
