Yarbo cannot create a successful map of backyard or a pathway Due to GPS dropout

Hello everyone :slight_smile:

I’m a kickstarter beta buyer from many years ago… I never received my original order and so this spring the full 2024 kit arrived… I had opted for everything at the funding stage.

I have unboxed everything related to mowing… The blower and snowblower are still boxed

Over the past week Imhave successfully installed the datacenter opting to attach to my chimney… It has 28+ satalites all the time and very strong signal.

Yarbo base is installed and works fine although the gps goes out when charging but maybe that’s normal.

Sadly nothing else is possible and yarbo is only a yard ornament… Im hoping a solution exists ..

I live in suburbia on a 70’ x 100’ property .. bungalow roughly in the middle … Backyard has a huge maple that currently is budding so gps is ok but will soon be gone for the yarbo unit.

Issue: .. gps, gps, gps … Makes no sense to me that with the data center, cameras, sensors, yarbo is useless without gps…

I was able to create a map zone for my front yard but cannot create a pathway due to gps dropout navigating between my House and neighbours house → soffits only allow maybe a meter of sky width from ground (tablet, cellphone, don’t lose gps even if resting on Yarbo when yarbo has no gps… Go figure). Really crappy as there is only about 6 feet distance of straight forward movement that will never ever have GPS

Can’t create a backyard map as tree, soffits, shed cause GPS dropout …

If infact Yarbo is useless without GPS then someone needs to make a 4 foot whip antenna for whatever current antenna gets GPS…

Im disheartened

Are the rover (V3.8.18), Data Center, and App all fully updated? Are your antennas all screwed down snug? Is your Data Center hardwired, or do you have it on a WiFi Extender? (If you are using a WiFi Extender for your Data Center, go 2.4GHz only and turn off the WiFi radio so nothing will attach to it – see if that helps.)

Sometimes it’s not GPS but other things like those. Sometimes.

What Ken said.

Also, ensure that wifi is NOT enabled on the core unless you are specifically using SmartVision, and only while using SmartVision. Otherwise, nuke it.

WIFI Packet loss pretty much seems to stall the core for up to a minute, and it manifests by saying “No GPS” on the app.

So, try wifi off unless actively using SmartVision. Hopefully that’s what you were running into.

@Steve You don’t need WiFi at all even for SmartVision. HaLow will carry the SmartVision data just fine.

As others have mentioned, make sure you disable wifi on the rover. This is a known problematic issue creator. Yarbo represents GPS based on many different factors that all impact its ability to operate. This can be confusing when you look at the diagnostics and have greater than 10 L2 satellites, and an HDOP less than 1 and it still represents as no GPS. This most likely means that there is a problem with the data path for the RTCM communication.

If you can post some screenshots of your diagnostics screen when you are having a no GPS issue in some of those problem areas, we can try and see if it truly is a GPS issue or something else. Include the Rover, Data Center, Status, and HaLow sections please. You can cross out any GPS coordinates.

Interesting.
For mine, Halow nearby, with Cell enabled, wifi off, Smartvision is not available.

Think we should bugfix the routing preference? All the theft mitigation goes away without the cell enabled.

Is your Icon on the main page displaying the HaLow icon or 4G? It will definitely not work when on 4G, and when you first open the app it takes a good 10 seconds or so before you can access Smart Vision. It gives a cellular error until then.

I can’t speak of a month ago, but as of late, anything out of bluetooth range will use 4G if wifi is disabled.

With wifi off and cell freshly disabled, but the core not yet rebooted, the app has a halow icon but is still giving the “cell not supported” message.

I’ll let it charge for a half hour and see if it changes. If not, give 'er the win31 reboot, lol.

Yeah hard power cycle both DC and Rover by pulling battery/power cables.

I have the same GPS issues. I can’t get around it on every run. I have to take manual control—so annoying. It loses GPS signal in one area and then I move it to signal area and starts again, then drops out in another spot with the same issue over and over.

And then this cutting drive issues all the time.





cutting height is probably excess grass above the discs. Lower the discs all the way down, shutdown the rover, detach the module and clean underneath with a garden hose really good. Consider removing the blade guards. The cut quality I hear is better and also less prone to buildup underneath. Only mow in dry grass, no rain, no dew. This will give you the best results.

As for the GPS issues, that could be a known issue right now with the current firmware. Can you post your diagnostics screen when it’s happening? Post the rover, Data Center, Status, and HaLow sections please. You can cross out the GPS coordinates.

Yes, I’ve tried those several times. Restarting is something I keep doing throughout mowing. I’ve cleaned it multiple times even when it shows an error, I inspect it and find nothing, the cutting disk spins freely. I also removed the blade guards. Yarbo went into the no-go zone and broke one of the guard’s metal edges, so I’ve removed them since then.

It’s stuck here for now posting the screen shot adjusting the cutting blade state.




I’ve enabled the issue recording, but I’m not sure what it actually captures.



I don’t see any logs that I can collect or share. The heartbeat signal is always strong.

The wait for blade error is most likely a bug. I’d make sure you have a ticket open for it.

As for the GPS, everything looks fine in the pictures you have provided. You could enable issue record for the job and turn it off when done. Le support know what time you started and note the times of the problems. That will help them narrow done the problems.

thanks, this was captured at gps lost signal at my other area now.



The AdjustAngle -2, when all the GPS/RTK is good, is a known bug that’ll hopefully get resolved in the next update.

For me, sometimes that error goes away on its own. Other times it doesn’t clear until I am manually driving it halfway back to the dock. Usually the rest of the day then completes normally, and other times I’ll get two in a row and I’ll give up for awhile.

Sometimes people unplug the ETH cable from the router side of the POE injector that powers the DC, just to see what happens.

Turns out, “Smartvision not available” is what happens. And for now, I’m blaming my cat.

:wink:

I get the same error all the time (GetAngleError). Support told me they are aware of the issue and it will be fixed in an upcoming update. Let it sit and it usually will recover on its own. If in 30 mins it hasn’t you can drive it out and swing it a few times. Sometimes a reboot works too if the other two don’t recover it.

Thanks everyone :slight_smile: … I will post some shots of what has been asked. Yesterday I reset everything and just moved yarbo’s base into my front yard (I put everything back into garage before night as I live near a college and expect fckery). Yarbo mowed my front yard so at least I can say it I’ve seen it work.

Basically anytime I get near being under the soffit of the shed or house GPS dies…
I’ve disabled wifi now and will see if better … will take diagnostic shots if no…

… my datacenter is the highest thing on my property other than trees… personally I am not confident in the metal poles surviving strong wind… if I don;t need the data center to be that high let me know… very happy to re-install it with the 90 degree bend.

I suspect that tree might be causing you some issues with the DC’s view of the satellites. You ideally need 120 degree view of the sky. Like an inverted upside triangle from the center of the top of the DC.

The diagnostics screenshots will definitely help us determine if you have a GPS Issue with the rover in the problem areas.
