The repo defines the protocol it authored. Is it better not to define stuff and leave it fuzzy?

Unclear why you formed the impression this was only iOS/ Android? That is not in fact the case https://github.com/samuk/awesome-meshcore

The current simulation is underdeveloped but can be found here https://github.com/samuk/caatingarobotics/tree/jazzy/src/agr...

The frame will almost certainly need more triangles

Rosys (a middleware layer https://github.com/zauberzeug/rosys) has rosys.driving.Odometer and rosys.driving.Steerer it's essentially a differential drive kinematic model.

Hoping RTK dual-F9P moving-base setup (M4 in the roadmap) largely sidesteps the worst of this — NAV-RELPOSNED gives us a real heading vector independent of wheel odometry, and the robot_localisation EKF can weight RTK heavily and odometry lightly when GNSS quality is good.

I did recently automate a greenhouse (heating, Hydroponics, fans, lights) it was just R&D rather than commercial so just used home assistant for it.

I did sketch out a slightly more 'professionalised' version, but haven't built it yet https://github.com/samuk/IoT-Greenhouse-Temperature-and-Irri...

I'd be pleasantly surprised if DJI had done anything open source, Ardupilot is pretty capable of course. I really want to automate the time consuming labour parts of horticulture, for me that's mostly weeding and to a lesser extent harvesting.

The software does explicitly support Jetson for example, and I'm sure the stack would run on Intel if you want it to.

The Mainline kernel for this particular board is _almost_ there 6.20 or so I expect. Armbian support is good.

Framweork have done the best they can within the confines of Intel licensing, still a long way from being able to fabricate it though

In a few years we'll all be using more open RISCV stuff of course.

TBC, just trying to get the platform and mechanical weeding working for now

If you can send me an open hardware Intel, or Jetson I'd happily use it.

Part of the point of this for me is to see what's possible with open hardware (down to chip level at least)

Nice, thanks! looks like a good one..

Payload is whatever you (or your startup) want it to be.

For me personally mechanical between row weeding is step one, then laser in-row weeding.

1. These on some linear actuators: https://www.getearthquake.com/products/fusion-drill-powered-... (they work surprisingly well)

2. Beyond that for in-row weeding a engraving laser on a Delta: https://github.com/Agroecology-Lab/Open-Weeding-Delta/tree/m...

Or if I'm feeling rich by then this third party weeder looks pretty good https://github.com/Laudando-Associates-LLC/LASER

3. For Seeding my salad crop https://reagtools.co.uk/collections/jang

4. Harvesting my salad crop https://reagtools.co.uk/products/quick-cut-greens-harvester

I live on a farm, I have sold salad commercially, these are largely tools I already use and own, just moved about by motors rather than muscles.

This is a smaller scale thing than arable. We're talking a step up from manual horticulture (which is actually what still feeds much of the world)

As cheap as possible, and no cheaper than that.

In my head it's £3-£5k, so by the time it's useful probably a bit more than that.

Initially keep it simple; Mechanical for between row weeding. I'll probably start strapping a couple of these to some linear actuators: https://www.getearthquake.com/products/fusion-drill-powered-... (they work surprisingly well)

Good advice on farms. I do live on a farm, so somewhat familiar with mud! Many of the worst problems are caused by moving 20ton tractors around IMHO, one of the problems small scale ag robotics may help with.

Will check out your Bno055 currently using the upstream one in Lizard

https://github.com/zauberzeug/lizard/blob/main/main/modules/... https://github.com/zauberzeug/lizard/blob/main/main/modules/...

Any review of that welcome too of course.

Quite interested in running robot<>robot and robot<>Farm comms over https://reticulum.network/ but that's a side project off a side project..
