There probably (certainly) is. But if you want to build a multi-purpose platform, you’ll soon be faced with a dumb challenge: nearly all interfaces (door knobs, taps, electric switches, cutlery, sponges, every single button out there, pillow cases, wrenches, hammers, signs…) are made for humans. Placed at human hand level. At human eye level.

Nearly all environments (houses, streets, sidewalks, factory floors, offices, toilets, bathtubs,…) are made for humans. Wide enough and tall enough (or short enough, for bathtubs) to accommodate human bodies.

So until we can find one or more form-factors superior enough to justify we adapt everything around it or them, betting that the easiest way to build a single multi-purpose platform able to do most things (and not n platforms for n+ use cases) is to borrow the shape most things are made for wouldn’t surprise me. Plus, you get a wider market.

And then, once you have happy-ish customers, figure out which of these human attributes and shapes aren’t actually needed to do the job.
