How about conveyer belts?

[Thurian]

If you could run conveyor belt to a deposit of ore or something and just have the iron be put onto the conveyor belt and the item is unloaded wherever the conveyor ends. Instead of constantly having to run to the deposit and back to unload.

This is a good idea

I also like the idea where you can build worker drones that haul for you
