A automatic robot that move storages cells

Why not a drone for long distance travelling and a terrestrial drone for little distances They can refuel on the charger or something like that

Whats the purpose?

For exemple when you move your base or a lots of things

Sorry that doesn't really make a lot of sense to me I wouldn't want a random robot flying around carrying all my items around.

Sure, but why random? You give it a destination and he go at this place

Or despawn, or get killed, or just break and lose all your items, or get stuck on a mountain. Sounds terrible on so many levels.

Entities like that can't despawn

And if he fly really up in the sky he can't killed or stuck anywher

I see entities like horses and dog/ cats get lose or de-spawn all the time, not sure if they fell though the world, or if they died, but i'm not about to put everything I own in a box and tell it to fly 9000 blocks.

It just has to fly 260 blocks and I talk about special entities like minecarts

And block range is totally specific to the distance to your "new base" or whatever, it also would be useless in the nether because there is "no sky" There is nothing special about minecarts?

Or animals with nametags

I don't really see any merit for this, it doesn't sound that useful and it doesn't really fit with the mod. Closed.
