How many Farmbots would I need to feed 2 adults and 2 children year round? What challenges might I run into?
Edit: Found a link to yield analysis https://farm.bot/pages/yield It appears the answer is however many Farmbots cover 549 square meters

Most people with any yard or outdoor space could get to the point of growing/raising a large portion of their own food without too much investment or work. A garden doesn't have to be manicured and ready for Instagram, it just needs to produce quality food. Meat and dairy would be the outlier lowering that % if you eat a lot of it, though chickens work well with a modest sized yard and finding a local dairy or farm for meat is still a big improvement on grocery store meat and dairy.
It has taken decades. And about 15 acres. And honestly I don't know how many hours. Tens and tens of thousands.
You can grow a small amount of your own food "without too much investment or work". To replace a substantial portion of your food with home grown takes a shit load of work and time.
We're on a larger piece of land actually, mainly because we have cattle that we may eventually use for meat and dairy. Were producing a large chunk of our food on about 1 acre though, and even then most of that is non-productive land around our house.
We have chickens that give us 6-7 eggs every day. Our garden is 2,500 square feet but well be expanding it a bit for next year. We're very hands off with our garden, though, compared to how most people do it. We don't till, partly to avoid any potential disturbance to the soil and partly out of laziness. We did have to water too much for a couple weeks in June, but that is about it for this year.
We haven't hit the 80-90% goal yet but are on track for that next year, our third year here. Right now I'd estimate us at around 40-50% with the rest supplemented mainly from local farms.
It is work, no doubt about it, especially if you aren't used to working outside. I haven't yet felt like the amount of work has blown past what it costs to buy groceries from the store though, and bonus that we know it's all local without any pesticide or herbicide use.
We live in the southeast US now, the climate is helpful for farming. I lived in Seattle for a few years and that climate would have been much harder to work with. I don't particularly like the task of preserving foods, here we don't need to do nearly as much of that.
Because of (a lack of) winter sunlight? Or something else?
We've had cattle on the land with us for the last two years, and though we have had to buy in hay its has been to supplement for 2-3 months rather than 5-6 months. We actually have the pasture space to grow and cut our own hay, that's just a comparatively big investment that we haven't taken on yet but is on the list to next year.
We don't own a tractor and aren't interested in getting one. That is our main blocker for producing our own hay, today everyone assumes you have a heavy tractor and all the implements needed to do the job.
As far as moving hay goes, we have bough square bails the last two years and aren't afraid of hauling it around by hand. If we bring someone in to cut and bail hay wed probably just spend around the same amount the first year around to buy a round bail trailer we could pull with an ATV or mini truck.
Not even close. Between some of them dying, many of them producing tiny output, and the difficulty of keeping them stored I exhausted my harvest in about four months.
I have a small patch of land, 10m x 10m, and I grow potatoes, garlic, cucumbers, and similar things. But I quickly realized I would never become self-sufficient, not unless I dedicated the whole patch of land to 100% potatoes, which would be far less fun and start to feel like work.
Interesting. Where I'm from (CEE), this would be about one onion per one or two days.
We've actually been running a test this year that has been interesting to watch play out. Our garden isn't very dense comparatively, and its planted into what was pasture before. We did cut the grass when planting and have trimmed it a few times, but its far from a garden free of weeds.
We also planted a space along the lines of a milpa or a chaos garden. We planted corn in rows, untilled and effectively just a grass pasture that we clipped short to start. When the corn germinated we followed behind with a variety of beans, peas, squash, and greens. It isn't nearly as productive per foot as it could be, but we haven't put much time into it beyond planting and a few deep waterings during a drought.
I think an hour a day is a totally reasonable expectation. To me that's worth it, but that wouldn't work for everyone and finding an hour a day may not be an easy ask depending on your lifestyle. I would argue, though, that if it isn't worth an hour a day to you you probably aren't too concerned with growing a large portion of your own food.
A small farmbot covers 4.5 m^2 and costs $3,000, an XL covers 18 m^2 and costs $4,500.
I think 3-7 sq m makes sense as a practical range, maybe round up to 10 to have some wiggle room.
It's a lightweight gantry system for seeding, watering, and (chemical spray) weeding.
Handy for big seeding greenhouses and some leafy greens.
It's not going to significantly help with you apple, lemon, orange, fig, grapefruit and etc. trees.
It's not going to significantly help with your potatoes and other root vegetables.
It's not going to tend to and protect your lambs, goats, chickens, etc.
FWiW I do have one spry old chap born n 1935 who can do all that already, has a few decades of experience, and can feed an easy magnitude more than just four.
Fun project, needs a wee bit of work.
And, there are scaled up Farm bots for farms, not just for oversized regular garden beds.

It hurts my soul that anybody producing a table such as that is using something as vague as a "cup" in their calculations.
American legal cup ? metric cup ? Canadian cup ? or one of the other ones.
Even if you narrow it to just the roughly the US you still have 4 + metric , so 5 different options.
and that doesn't even account for people just using the cup they have to hand.
It's not a rant at you, it's frustration with non-specific, arbitrary units.
US cups and metric cups are different?
But, wow apparently the FDA rounds cups in nutrition labeling to be exactly 240ml “legal cup”, which I agree is super annoying. It’s 1.4% more.
“For purposes of nutrition labeling, 1 cup means 240 mL, 1 tablespoon means 15 mL, 1 teaspoon means 5 mL, 1 fluid ounce means 30 mL, and 1 ounce means 28 g (21 CFR 101.9(b)(5)(viii))”
It hurts my soul that it's using a volumetric measurement for leafy food, like if you cut lettuce leaves into pieces, they have the same nutrients but take up way less space, so 3 cups of roughly cut lettuce leaves is different from 3 cups of finely chopped lettuce leaves, which is also different from 3 cups of uncut lettuce leaves. Just give it to us in mass or calories please (like grams or fractions of an oil barrel's mass, or fraction of a barrel of oil's calories and nutrients).
a bit steep still, plus the maintenance nightmare of keeping 31 machines working..
it's a fun farm to envisage though.
p.s. I don't think that this gantry has very harsh stiffness requirements; I guess one could scale the thing to a larger size reasonably easy -- akin to a configurable MPCNC machine.
