Are robot vacuums always circular, wouldn't a single 90 degree or similar section be useful for accessing corners

Mostly circular, some have slightly asymmetric shapes like Eufy e28. The mid range and higher typically have an extending arm that handles edges or corners

I am bone tired of slop. This looks like a useful thing to build (the cameras in existing closed source robo vacuums creep me out), but when people don't even write their announcement blog post by hand it gives me zero confidence in the project getting anywhere meaningful. Perhaps not the place to share this, but it's depressing. I hope this proves me wrong.

Isn't a AI generated blog post better than someone building a useful thing and nobody hearing about it?

No, it's not. It's an indicator that they're prioritizing the easy things surrounding the work, rather than the actual work.

It's a bit of an indicator about the effort they put into it. If they don't even write their blogpost themselves the question of "how much effort and thought did they put into the rest of their code / product". Now, obviously they might just be bad at writing blogposts but surprisingly often it seems to be a decent red flag. Because the thing is that the less effort you put into that the more anyone can just...reprod…

Or the time they had available. Maybe they have a full time job, parents to care for, kids to care for. But still they wanted to scratch the itch.

I don't know why you would say that, my Xiaomi s6's wheel motor died, I was bummed about it. I ordered a replacement motor, and to my surprise, I only had to open one or two screws and the motor module popped right out. The module had a nice slitting connector. I put the new motor back in and I was done. The thing must be at least 8 years old by now and it's still chugging along. I now passed it on to my parents and…

Agreed. I have a 6.5 year old Roborock S5 Max, and it still works fine. I've replaced a few parts (can still get on AliExpress), but other than that no issues. It's cleaned 74km2.

Same here: 10 year old Roomba from the 6xx series, still going strong. I bought official replacement parts for a wheel, some brushes and a new battery: Replacing them was very easy - just a few screws, no glued-together parts.

The brushes usually don't go all the way to the sides of the vacuum, that's why many of them have an additional circular brush on the side to get into the corners and scoop the dirt to the big brushes in the middle.

No need for edges, also makes navigating through narrow things easier.

> oomwoo is organized so the community can build it in parallel. The robot and its software are split into self-contained modules. You pick whatever module interests you, work on it whenever you want, and submit your work as a pull request. Multiple people can tackle the same module — the best solution surfaces over time.

I think one major advantage of open source over commercial alternatives, is the possibility of endless improvements. Similarly, 3d printing as a manufacturing method allows for a short iterative cycle, high degree of design freedom, customisation as a product feature, local production, and an high degree of repairability.

It’s going to be interesting to see how well git(hub) and discord serves as collaborative tools in this case. Hardware files are often binary, hardware components have complex interfaces between them, and hence depends more on human communication and collaboration.

I really hope this project succeeds. I’d love a cloud free robot vacuum that I can trust.

Being circular allows for zero clearance turns.

If you imagine a square robot traversing a wall and approaching a 90 degree inside corner, it can’t make the turn and would also be unable to make a perpendicular move to get more space.

That said Eufy, Makita and others make square-ish robots.

Interesting project. Aren't most modern robot vacuum's using image processing to determine whether to stop or not now though? How is Lidar going to help you avoid the cat's diarrhoea on the rug?

There's a camera module in the bill of materials. I suspect it uses both.

The issue I have is the documentation and “status” is slop. Looking at the repo, how much of it is even real? There’s supposed to be a build-along on YouTube but nothing there yet. The BoM is a bunch of aliexpress modules which is ok, but what about the chassis? Is that image generated? The RFC calls to generate accurate models for the components, but the render looks like a full assembly?

When they get to the point of shipping a kit, why would I care? It's open source, just fix things. It's not rocket science, I'm just no good at working out the baseline machine that has parts to do the things. So I can't help at this point. I don't expect a finished product. The value to me is the customizability and figuring out how to make it do what I want it to do. I'm sure that's not for everyone but like I have…

But it's not even a first draft. There are only pictures and markdown files.
