You guys are killing it! Machine learning + sustainable agriculture is a passion we share!
Came here from Hackaday. I'm not a farmer, but I like to see how Open Source makes this sort of thing possible. Great project. Best of luck for the future. I've subscribed so I can watch how you progress.
I found this because I'm a regenerative farmer in Japan and former Computer Engineer looking to get back into building robots for my farm and have been researching solutions. This one looks like it could work on my land (I'm at the base of a mountain forest so not entirely flat by any stretch).
Come here from my Google News, glad to see this getting popular. Best wishes for you and this big mission!
Thank you!
Looks fantastic - kudos! Greetings from Denmark from an experienced open source founder slowly turning wannabe farmer 👏 we’d love to build one over here, help contribute and test how it handles colder and darker climates!
Thank you we would love your help! Best way to stay in touch is on our forum: community.twistedfields.com/
Awesome platform. Makes so many solid engineering choices! So many impractical "farm robots" out there. Acorn is built for muddy, messy farms.
Thank you! Yep Acorn lives outside full time. I (Taylor) worked from home during part of our recent rainy season and Acorn was up in a field getting hammered by storms, but when I returned it was still working great!
This is right up our alley since we’re already thinking/planning a similar project based on farmbot but for the beds in our market garden. And coincidentally we have a bicycle tyre frame that straddles our beds that we use for lying down to weed with a canopy. My partner is in the process of making our place more automated such as door controls for the barn, greenhouse climate controls and invented some automatic self cleaning poultry waterers (currently on version 3.0). Lots of Raspberry Pi here at Humblebee Farm in NS, Canada. We’d definitely be interested in following and sharing in your project development. Best Wishes. E&S
Looking forward to seeing where this goes. Excellent work!
Awesome guys! Good luck
This is incredible to see! It helps battle internal nihilism about our efforts to make this world a better place
Very cool, I am looking forward to seeing this evolve. I really like that it is open.
Heyy! You're aware of Open Source Ecology(OSE) right? This is that kind of goodness, thank you!
Unofficial Social Media Manager/Networ-er here, here is a but of an explanation of what OSE is, then at the bottom a link to our *discord server* . I'd love to talk about this idea; i was thinking of a "farmbot but the frame is a rover" for a while so this project is amazing!
ANYWHO
Open Source Ecology or “OSE” is a basically a group dedicated to making all the hardware needed to build, and run, a small community/farm/town, ALL Fully Open Source
It is a bit complex, as it is such a broad, multidisciplinary goal, so I’d recommend first watching the TED Talk made when the group was founded:
ruclips.net/video/S63Cy64p2lQ/видео.html
Then I’d recommend looking around these pages:
The wiki where the “real work” happens
wiki.opensourceecology.org/wiki/Main_Page
(FYI it is a bit of a mess, and it’s search engine is using tech from the 90’s)
The more basic (mainly announcements) page:
www.opensourceecology.org/
There are also offshoot groups:
- The “Open Building Institute” specializing in buildings and houses (both design, and construction)
- The “Open Circuit Institute” which specializes in circuit design, and decentralized production of these PCBs
Given that the wiki can be hard to navigate, I can be a “Sherpa” of sorts, feel free to ask any questions you have!
I see Farmbot in my future 🔮. Great work 😄.
So absolutely cool!! Thank you for creating this, and thanks again for making it open source.
Just a heads up, great work. Power of open source!
It is awesome! Which motor do you use at steering system? Are you guys using some gears? I study mechanical engineering in Universidade Estadual do Oeste do Paraná, Foz do Iguaçu, Brazil, and here we are developing almost the same robot. Let’s exchange some information!
Join our community site at community.twistedfields.com to get answers to technical questions, would love to exchange info!
This looks great!
Magnificent project!!!
I really like the use of 26" fat bike tires. It seems durable enough and very economical. If you can get that design sorted and offer some of those parts for sale, that would go a long way towards attracting interest and hopefully standardizing some of these open source ag robot designs.
Not to be a negative nancy, but the close-up of the custom pcb has a few points where the silkscreen is getting toasted, most notably by the solar input.
Hah yes. A few reasons. I did not do thermal vias on that PCB and I used 2oz copper so I had to hit it hard with the heat gun to do some rework. That may have been what you saw. But also on one of the PCBs I fried the current measurement chip when I hooked up a battery to the solar input for use at night without first disconnecting the supercap. So current tried to rush from the 52v battery to the probably 30v supercaps and instantly fried that chip. When I redesigned the PCB a few months ago I broke off the power section to a separate board so rework, replacement, and upgrades are easier, and I went back to using thermal vias. One of the upgrades will be a dedicated battery input so I am not unplugging stuff to add in the battery when running tests at night (I am a night owl). - Taylor
@@twistedfields totally understandable. Youre doin good work on this project 👏
Wish you all the best!
Slap a "Farmbot" in the middle, and you are golden!
Haha yes! I just said that!
Just found out about this, really cool project you're working on. Sometimes think i chose the wrong subject in uni...
2:52 love the application of super capacitors!
you can see that they put a lot of work in it
Great intiative. Would be more than happy to join.
Thank you that would be great! Please sign up on our forum and say hello if you haven't! community.twistedfields.com/
Iam working on a similar project. I see you used ebike wheels with motors. Where did you buy them from and what are the power ratings. I need help in that area
Details here: community.twistedfields.com/t/motor-and-controller-selections/52
Awesome!!
Came because of the BLDC driver 🙂
Very Interesting project, how do I go about getting/building one ?
Very interesting !
Great upgrades! What is the approx BoM price currently?
Good question! I don't think we've quite tallied all that but straight BOM cost for the base vehicle is probably around $6k-10k. We will be making a new version intended for reproduction which will have clear documentation and BOM cost once that is ready!
When will Acorn merge with Farmbot?
Great.....I would like to help in 2023.... Cheers
great, how to make this thing work on rough terrain? In the field the route is very rough
The current vehicle is great on rough terrain! Since it is four wheel drive, has large tires, and it very light, it floats over big bumps with ease.
@@twistedfields Crops grow in loose, fine soil because their roots are fine and small. Rocks and big hard chunks won’t grow anything. You need to learn about plants to build a useful agbots.
Rough terrain is not crop land. It might be a forest, but the rougher, rockier, it gets, even forests are compromised.
