Here it looks like its squeezing a grape instead: https://www.youtube.com/watch?v=HyQs2OAIf-I&t=43s Bit hard to tell whether it remained intact.

The leaf on the darker grapes looks like a fabric leaf, I'd kinda bet they're all fake for these demos / testing.

Don't need the robot to smash a grape when we can use a fake grape that won't smash.

The bananas are clearly plastic and make a "doink" nose when dropped into the bowl.

Haha show the whole room and work either on a concrete floor or a transparent table.

This video reeks of the same shenanigans as perpetual motion machine videos.

welp i guess i should get my sight checked

And how it just dropped the grapes, as well as the banana. If they were real fruits, you wouldn't want that to happen.

I remember a cartoon where a quality inspection guy smashes bananas with a "certified quality" stamp before they go into packaging.
