Cutting disk design.

Yeah, I’m with Deixi on the new mower intro. I just started using Yarbo this year, and now after 3 months of training, cleaning and fixing the bot, we find out there is a brand new model out soon!! How about an almost free retrofit kit for those of us stuck with the old hardware. I’d have to agree also on recommending Yarbo to those who ask how I like it. Answer is …right now I’m not happy!!

Hi Deixi,

I completely understand your feelings as an early adopter, and I truly appreciate your candid feedback. First and foremost, I want to express our sincere gratitude for your continued support. It’s because of users like you that we’ve been encouraged to push forward with the development of our innovative products.

The release of the Mower Pro was driven by demand from users with larger yards, tougher grass, or more complex terrain. That said, we remain committed to continuously improving the functionality of the current M1 model.

Regarding the issues you’ve mentioned, I will forward all of your feedback to our product team to help evaluate the development timeline for necessary improvements.

I’d also like to share the current progress on the issues you raised:

“Not being able to mow on slopes without leaving lines of grass” and “a working rain sensor”: In the latest update, we’ve optimized the mowing algorithm for slopes and added flexibility to adjust the rain sensor threshold. I understand that this “rain sensitivity” adjustment isn’t the ultimate fix, but it is a step toward improving the situation for now.

Vision system and no-go zone issues: These issues have been a primary focus for us, and we are actively working on improving the vision system, particularly the rear camera, and resolving problems related to entering no-go zones. We recognize how important these improvements are for the mower’s safe operation and to ensure it stays within boundaries. Additionally, we’re exploring solutions to address the GPS-related challenges.

Cutting discs: We are currently testing more durable cutting discs and have previously extended an invitation in the forum. Based on the feedback we collect, we will make informed decisions and implement necessary optimizations.

For the other issues you’ve mentioned, I’ll be sure to pass them along to our product team for further consideration.

At Yarbo, putting our users first has always been our guiding principle, and that commitment will remain at the heart of our development efforts moving forward.

Thank you again for your feedback and support, and please feel free to reach out if you have any further questions or suggestions!

This one single problem prevents me from mapping about 15% of my 2 acres, and the only way is to do “deadends” for that portion, which is at over 50 dead-ends now, and I will need to go to about 150 dead-ends to entirely cover the rest of the hills. Not a mention of that in the new update?

Not this update but it is on the road map I believe

Where can we see that? The only hill stuff I see is a fix for the small geometric misalignment of the curved surface.

This is what I see, sadly.

So yeah… the mowing season is half over and I need to go out and make lots more “deadends” to get Yarbo to mow my hills! Oh boy…

@offgrid - I wonder if you can make use of long Areas top and bottom of the slope and Stubby Deadends and Pathways mowing the slope instead and if that would be any better than several parallel Deadends. There’d be no reverse heading back down the slope, which Deadends do. It would always be forward mowing up and down the slope. Dunno if that’d be helpful.

Kinda what I do. I have a large area at the bottom of the slope and deadends going up the slope. Lots of parallel deadends. So Yarbo is always pointing uphill.
Or are you suggesting several parallel pathways instead of deadends?

Instead of Deadends, use the Stubby Deadend - Pathway - Stubby Deadend in parallel method, and put your Stubby Deadends in the appropriate order in the Work Plan. This will have the mower go up, to the next Pathway over, come down – no reversing. I don’t know if it would be any better or worse or have any other advantage other than no reversing. If you’d like to try it, I can go into detail on how to set it up. You’d be the test subject - I’ve not tried this.

There’s an even worse hack I came up with to help snowblow driveways with a slope, and it’s eerily similar.

Both are in my head if you want 'em.

Not sure that short Deadends between parallel Pathways would be less work that just the parallel Deadend method I’m using, but I’m game. Can you sketch the idea, I’d def like to find a better method to slope cutting?

The method I use cuts the grass evenly, and will be even better once we get a point to point straight line drawn, since it cuts going up and going back down. It may be that your method would be uneven cutting, since the downhill cut would be much faster than the uphill cut, right?

You asked for it! LOL!

“Stubby Deadends” (the mustard color things): Create a Deadend, Start, drive until Next goes yellow – very short, all you need. During the Work Plan it will mow the Deadend and then mow on the Pathway to the next Deadend. I map Stubby Deadends in the direction I want to go so the rover doesn’t spin/turn too much.

Try a couple, make sure it works before drawing a bunch more. Sometimes navigation doesn’t go the way you’d think. I typically draw these so the start or end point of the Deadend is on the Pathway a foot or two. Not sure you have to. I typically create the Pathway first and then add the Deadends to it.

It is possible you only need one Deadend per Pathway, and the navigation will choose the best pathway. You’d have to experiment. It could be you’d start at the bottom of the first Pathway and map all the Pathways and only Deadends 5, 2, 7, and 4, you’d put those in the Work Plan, and the rover would take the attached Pathway. But, as I said, sometimes Navigation kinda does what you don’t expect, as it’s all math, and it’s comparing the exact lengths of everything.

You don’t need to mow the Areas unless you want to. If you do mow them, I’d do them last to clean up whatever the rover does while mowing and turning on the Stubby Deadends.

I hope this makes sense and turns out to be fun, useful, and profitable.

I’d wonder about a single area that you do not mow, and a bunch of Stubby DEs left-to-right.

Mapping would be easy, just keep driving forward to make 1,3,5,7,9, then head up and make 2,4,6,8,10 and keep the start points about one yarbo-width apart.
Workplan would just be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. And if it mowhawks, just keep adding more, lol.

Maybe I’m missing something, but don’t you need something between the Deadends to mow, like a Pathway? Yarbo doesn’t mow the navigation lines it takes between Deadends (and it shouldn’t).

Oh, yeah, small caveat.
But the LINES!

I guess we’ll just save that one for when we can tow a push-mower around.

Ahh now I see what you are doing, thanks Ken!
It does look like a lot more work than parallel deadeneds, I’ve done 50 so far, and probably have another 150 or so to do. Your method would triple the work I think! But it would be faster mowing by 2X probably, so for folks who have a lot of long hills, this might help them out. For me, my steep parts are maybe only 40-50ft long, so deadends don’t take a ton of time to map, or mow for that matter. Keeping them straight though, is a bit artsy-sciency, I have to paint the lines on the grass to keep a straight line with Yarbo… so much fun…

Now, now, @steve! I was yelled at for suggesting using Tow Mode to pull a petrol mower around because “muh safety”! Yeah, well, I don’t see Yarbo sucking up all the twigs and leaves and other debris from the huge wind storm here in the US Northeast yesterday!

My petrol push mower grinds up and bags stuff. And if I don’t gotta push it, that’s a win.

@offgrid - How many…? Holy smokes! Well, do whatever works! Give this some love if you haven’t: Deadend Area: Automatically create and mow a series of parallel Deadends

And CUT BACK ON THE COFFEE. You want those lines nice and straight.
