  "If you have another way to donate in mind"

Seems like this would be an ideal project for a kickstarter, that way at least the project could create a more informative project page and detail exactly how they hope to spend the money with perhaps the goal of building a prototype in a given time-scale.

At the moment it looks a bit too much like someone's had a great idea, done a bit of initial design and thrown together a wiki page. It doesn't seem serious enough for me to donate at this stage.

gustoffen• 13 years ago

It might be too early for a kickstarter, but looks like it hasn't stopped someone from donating pi bitcoins - https://twitter.com/FarmBotProject

roryaronson• 13 years ago

Hi, my name is Rory and I am the one behind the project.

We are working towards a crowdfunding launch in 2014 as stated on page 47 of the white paper: http://www.scribd.com/doc/169536137/FarmBot-Humanity-s-Open-...

We've received a good amount of donations so far and will be ordering materials for the initial design this week and next.

I'm currently recruiting other students at my local university to work on the project, and we plan to flesh out the wiki with timelines, design files, and progress updates soon.

Thanks for checking out the project!

_mulder_2• 13 years ago

Thanks for clearing it up. However, I'm still not sure on what my donations would be used for at this stage (I guess you could say a lack of transparency) but I wish you the best of luck and hope you get enough backers to make this work.

Could be something of REAL benefit to the world, which is more than most HN stories can say.

Very cool. It would be awesome to automate as much as possible of permaculture and everything you need to create small communities that can survive entirely off the grid in a way that affords people plenty of free time.

People who did this might want to also check out the Global Village Construction Set:

timdiggerm• 13 years ago

off the grid, yet with a powered robot?

Zikes2• 13 years ago

Plenty of off-grid power options, like solar, wind, and water.

VikingCoder• 13 years ago

I'm reminded of this, my favorite TED talk:

http://www.ted.com/talks/willie_smits_restores_a_rainforest....

He talks about turning a de-forested area back into a rain forest. It's like an algorithm for sustainable living.

eksith• 13 years ago

This seems to work on a very similar principle to automated industrial cutters like those you would in factories slicing fabric or even automated drawing machines or dock cranes.

Two tracks on either side with one main gantry and tool in the middle. The design is very simple (which is very good) and I think the principles are straightforward enough for the DIYer to begin tinkering almost immediately. 3D printers, while getting cheaper, aren't as cheap as inkjet printers and until that becomes are reality, making parts will be a bit expensive.

But for a small green house version I can see someone using furniture drawer tracks or screen door tracks from the nearest hardware shop and begin building one of their own. Someone with basic woodworking skills can put together a basic version fairly quickly. Arduino programming is also pretty simple that a novice can get working quickly. A motor controller board will really help with a smaller version.

I especially like the design for the Crop Circle Bot : http://wiki.farmbot.it/file/detail/Sketch%2C%20FarmBot%20for...

Qworg3• 13 years ago

I think the follow up circular design is far more efficient. A huge X-Y table is terribly expensive in materials.

fnordfnordfnord• 13 years ago

In maintenance, too.

jabits• 13 years ago

I think x-y scalability would be easier/more versatile/easier to locate than an ever-enlarging circumference.

tocomment• 13 years ago

This is really cool. If these were ever used at scale it could make organic farming cheaper than non. For example instead of pesticides a robot like this could pick off bugs (and or scare them away).

It could also pull weeds getting rid of the need for herbicide.

lnanek2• 13 years ago

The design seems fundamentally unscalable due to the rails. I've been to farming areas and fields can go on for miles.

They could have come up with something far more powerful just by sticking it on the front of a tractor and having some tanks/bins for consumables.

Heck, they could have even started from common irrigation systems where you can have 400m of pipe on wheels you roll across the whole field.

I have to wonder how much farmer experience anyone behind this has and if they even looked at current farming equipment before just scaling up a computer printer and sticking a different end on the head.

pampa• 13 years ago

Dont you see? It's a robot for growing organic weed! Maybe some lettuce on the side.

Here is an idea for a startup: Shipping container weed farm. Order one online, plug in, insert seeds, press button.

yellowbkpk• 13 years ago

Ever since the Telegarden [0] shut down I've had an idea like this in the back of my mind but not solid enough to give it a name or draw plans. I'm glad someone is making it happen!

As someone who does farming (part time), I don't see these being practical. For low value bulk crops (corn, wheat, soybeans) the robot is too expensive and existing mechanization is too good. Even for high value stuff (grapes and other fruit) it will be too expensive. Maybe inside a highly controlled greenhouse this will be practical, but there are no food crops that are economical to grow inside a greenhouse. (It is getting there as high-tunnel becomes cheaper to install.)

As an aside, mechanical harvesters for grapes are hilarious. You still need people to run them. One person's job is to find and remove possums from the fruit bin before the critter is buried by a thousand pounds of fruit.

It is a distraction to talk about the gantry, XY or radial. Any gantry based system is going to be a headache from the start because you've got those rails cluttering up the space. Eventually you'll find something the robot cannot do and then you'll be trying to figure out how to get your general purpose tractor around without crushing the gantry.

The radial system is cute, except now your installation and operating costs scale linearly with the amount of crops. With an XY system, one can plant more and extend the rails and have the existing robots do more work. Not possible with the radial system, unless you are going to physically pick up and move the units between circles few times each day. If time is tight (plague of locusts coming in tomorrow, need more robots to squish them) you can increase the robot density by sliding more robots onto the XY gantry. Not possible with radial.

Ultimately it will be about the vision processing and manipulators. And then you might as well mount the vision/manipulator unit on a tractor and have a robot-tractor drive up and down the fields, just like any other piece of equipment. Vastly cheaper and more flexible than gantries.

Eventually we will get there, but it probably won't be until vision processing and lidar gets a whole lot cheaper. We might be on the cusp though, based on the computer vision advances in video gaming.

User roryaronson, I've done a lot with robotics and outdoor electronics too. If you want I can give you a fairly lengthy piece of constructive critism about your whitepaper. You've got a lot of good ideas in there, but just as much misinformation.

diydsp• 13 years ago

Your post is the epitome of how domain-knowledge trumps idealism.

I look at this and instantly think "Dirt. And water." Dirt and water will destroy their "machine." Whoever conceived it doesn't respect that farming involves dirt. And water.

As you remind us above, THE TRACTOR IS THE ROBOT. The tractor is safe from Dirt and water. Unless this is some desktop thing. Even as a gantry system, their rendering is naive. ISHYGDDT.

siavosh• 13 years ago

As someone who knows nothing about farming or gardening, I'll defer to the points you made as they sound very sensible. But as a software guy with an interest in salt-of-the-earth hobbies, I'd love to play with one (if I had a backyard that is). The thought of a robot that runs on a seasonal calendar that automatically harvests fruits and vegetables for my salad is too cool. To peer out your kitchen window and see a robot till the earth and harvest your small garden to feed you and your family is straight out of science fiction, the optimistic type.

That said, having a high tech piece of equipment with a bunch of moving parts outdoors does seem quite problematic and headache inducing. Here's to reaching the cusp fast....

keenerd6• 13 years ago

But as a software guy with an interest in salt-of-the-earth hobbies, I'd love to play with one.

Like you said, high-tech outdoors is troublesome. If you want to get a head start on this sort of thing buy an outdoor robot chasis (or make one if you can hold a screwdriver, it'll save you a grand or two). Throw on a kinect, all the cameras you can fit and all the lidar you can afford.

First, teach it what rain is and how to quickly get back to the safety of the charging port. Second, make it navigate around the garden without destroying the plants. Finally, teach it what to look for (pests, damage, ripeness). Don't bother giving it manipulators, just have it log findings and generate reports. When you get home, it can tell you exactly which plants need attention.

HeyLaughingBoy2• 13 years ago

Yup. I went through the site and I still don't know what problem it solves. Modern ag equipment is scarily efficient and fast. The farmer who's just driving into the field when I leave for work in the morning is towing out carts piled full of corn by the time I get home in the afternoon.

As an aside? How to mechanical harvesters for grapes work without breaking/getting tangled in the wires supporting the vines?

keenerd6• 13 years ago

You need to spend the rest of the year pruning and training the canes to be harvester friendly. The harvester itself shakes and beats the berries off.

http://www.youtube.com/watch?v=fv-AnyvWL7g around 38 seconds in.

Quality is questionable, as it will also harvest the unripe secondary clusters and any rot. (There are probably visual systems for cleaning these out.)

Grapes (and a lot of perennial fruits) are a little oddball in this discussion though, because they are very low impact. For example, you rarely (maybe once when first planting) have to till or fertilize or spray for weeds and we've got plenty of biodiversity in the turf.

Qworg3• 13 years ago

As someone who lived and worked on farms, I agree that they're not practical right now. That said, I'll take on some of your other points.

"there are no food crops that are economical to grow inside a greenhouse" - there are many organic lettuce/greens growers that put lie to this statement.

I don't like the gantry system, mostly because what you stated. Also because it is _extremely_ expensive vs. other methods. If you're doing that, you might as well just put it on wheels and have it drive around.

The radial system can still run more robots - I don't see any restrictions past weight on the arm. It is the equivalent of a circle sprayer, just with robots instead of water.

As for cheap vision/LIDAR, it is most certainly not driven by games. The big Deere tractors are moving away from LIDAR towards sets of stereo cameras because the algorithms are getting better and the cameras are much cheaper and more robust than LIDAR.

I see this device fitting a niche in "black greenhouses" where there aren't any humans involved at all. Totally recycled, totally hermetically sealed environments, like a clean room for plants.

keenerd6• 13 years ago

Regarding greenhouses, any example you cite I can say is way out of economical norms ;-) But the only way to make organic work (without throwing away half the produce or drowning the field in the few allowable chemicals) is to either do it indoors or in a part of the world where the pests don't exist yet. But that is neither here nor there.

How do you get the extra robots installed on the radial systems? With gantry and wheel based systems, you plop them down at one end of the field and then they re-arrange themselves.

I was specifically thinking the advances in time-of-flight LIDAR that seem to be for short range (several feet) gesture recognition. Not for object avoidance (Deere's use case) but on the wrist of a manipulator, where you don't always have the space for a stereo-optical setup.

One day hermetic greenhouses might make sense. Until then it will be cheaper and (arguably) less impactful to grow the veg someplace with reasonable weather and pests and ship it instead.

bglazer• 13 years ago

I can't read the whitepaper due to work network restrictions (scribd? really?) but superficially this seems more directed towards DIY-er gardener types rather than industrial farming. That is to say, people who have no need for a giant combine harvester.

For that purpose it seems to have the capability to automate some tedious jobs quite nicely. I would pay for a machine that grows vegetables in my backyard with little to no input from me.

That said, the possum remover must be the most hilariously bad job in farming.

keenerd6• 13 years ago

They've probably fixed the possum thing by now :-)

Your comment makes me wonder what a good pricepoint would be for such a system. How much money and how much space would you be willing to give up, for example.

Less hypothetically, why the fixation on machines? We've got all sorts of crazy services these days. How much would you be willing to pay for a gardening service that maintains your garden for you and occasionally leaves a crate of produce at your backdoor? It would be like a lawn service, but without all the terrible effects on the local ecology.

wiredfool• 13 years ago

I let kale and chard go to seed last year. I've had more kale and chard this year than I can harvest. Almost all of it volunteer. Also some other random greens that make a quite nice salad.

On the other hand, I've put in a ton of effort on tomatoes, and gotten very little to show for it. The climate just isn't friendly to them.

lingben• 13 years ago

I can see it applied in the right place.

check out this short video on vertical farms in Singapore http://www.youtube.com/watch?v=2nFQOkzEjxQ

keenerd6• 13 years ago

Okay, that is pretty awesome. Some thoughts... greens are probably optimal for this because they are fast to go from seed to produce. And 100% of the output can be sold, with basically no wastes. Singapore is also optimal for greenhouses. The temperature there is 23C-32C year round, so you don't need HVAC (just air filters on your vent fans) and you can grow continuously.

The waterwheel thing is clever not for the energy efficiency (it'll be the same regardless) but because it greatly reduces the amount of mechanics/electronics that are exposed to the greenhouse humidity, greatly improving reliability. (Installation cost is probably the same as if you had a gearmotor on every tower, just because the funny waterwheel is probably not an OTS part.)

But even in the video they call it a "premium novelty for consumers", which basically means not yet economical. And who knows how much of it was backed by the mentioned incentives. (They show some prices at 5:12 and 5:41, maybe that can give an idea.)

joshuaellinger• 13 years ago

You should read PG's column about doing things that don't scale.

Yeah, this will never be practical. But most of the building blocks that go into it are thinks you would need to automate farming. And it is interesting that someone is taking a stab at it.

speleding• 13 years ago

"there are no food crops that are economical to grow inside a greenhouse"

The Netherlands has so many greenhouses they can seen from the space station without a telescope, and many of them grow food crops (tomatoes and paprika being the largest two)

Bjorkbat• 13 years ago

Some input as a former organic farmer: wheels.

But a start is a good start, and really wheels can be a hassle, seeing as tractors can't operate on muddy soil (well, shouldn't).

I'm actually somewhat glad someone is doing this. I had a similar idea way-back-when, for gardening, but I had no idea how to handle the issue of having the seeder/weeder/watering device climb over taller vegetables, such as tomatoes, which can get up to 4ft tall, or the mighty sweet corn plant, which can get up to 6ft and higher, at least not without making the thing ugly as all hell or severely manhandle the crop. This is an attractive looking step in a good direction.

I'll follow you on Facebook and occasionally remark about the hell that is trying to grow vegetables in East Texas.

prawn• 13 years ago

Half-baked pie in the sky musing:

What about a spindly-legged robot (picture those tall things in Half Life, or the killers in War of the Worlds) that wasn't constrained by rails? It used a camera to identify where to safely step, returned to a base to charge (solar on shed roof nearby) or replenish its (small) water and seed supply.

Sensors helped it check water moisture and know when to rewater. In its travels, it got a picture of which regions had the most sun, so it knew what would grow best and where.

Wonder if it could (with camera or sensor) identify what was growing where to help with decisions, or even remove upcoming weeds before they got established?

Debugreality• 13 years ago

I'm most interested in pushing this technology forward so we can use it on the moon or on mars. I think the moon would be a much more attractive destination if they had a few nice big gardens growing up there...

smoorman10242• 13 years ago

Really interesting idea. I could see this being used to remotely manage a farm from anywhere in the world. Picture a dashboard with hookups to your video feeds and statistics. When it's time to harvest take it out of the ground put it in a hopper and wait for pickup.

Not to mention the impact of testing different field configurations in varying climates all over the world. Whether the robotic design of the system is cost efficient or not, we should be at least collecting and sharing this data now.

stretchwithme• 13 years ago

Eventually, robots will be growing all kinds of food. The roofs of our houses will be covered with gardens.

They'll even inspect plants at regular intervals and remove bugs. They'll decide when fruit is ready to pick and share all the data with systems that buy, transport and use produce.

weavie• 13 years ago

I would definitely be interested in some form of 'gardening bot'. This but at a smaller scale just for my garden.

At a smaller scale, I can sow the seed myself. I can harvest myself. What I do need automated is the areas where I consistently fail when trying to grow my own vegetable patch. Watering is the main one. Just having a sensor to detect when to switch on and off the hose pipe would probably save most of my crops. Slug control would be another - something to detect when a slug gets to close and zaps em with (preferably) a laser.
