Whether big or small. We all have that one thing from Scifi we wished were real. I'd love to see a cool underground city with like a SkyDome or a space hotel for instance.

Here is something we don't have that I think we could: Automated vegetable farming.

I've seen these watering gantries that are fixed at the center of a circular field and then rotate radially around that point to water the field. Could you use that as a rail with an effector arm on it that can plant, weed, tend, fertilize and harvest the field, such that in goes seeds and out comes vegetables? Without the liability of free roaming robotic tractors and combine harvesters. Surely the issue here would be software.

I'm into hydroponics as a hobby grower and there are certain techniques for veggie growing that are set and forget. You plant and harvest only, no weeding, no watering. As far as I understand, traditional techniques are still cheaper though

Those are called pivots, and what you are saying seems plausible: there are vision algorithms to recognize and selectively spray weeds (see Bilberry ), recent prototypes with light-pressure grabbers to gather fruits and soft vegetables.

Even for harvesters, there are projects to automate harvesting and swapping the grain trucks (see Outrun ). GPS-guided (or assisted) tractors are already a thing.

Agriculture has some interesting innovations, but it often gets bogged down in corporate acquisitions and monetization.

I've seen a project for adapting Reprap 3D printer technology to a raised bed garden, with a multi-function tool head that can individually plant seeds, it weeds by poking weeds deep into the soil, it waters individual plants according to that plant's need...so I thought why not scale that up to multiple acres in size?
