Is this the "dreaded" map drift at work here?

Hey everyone, I’d just like some confirmation here from others who may experienced the same thing. The map for my Yarbo has been just fine with it sitting over the winter, but with the arrival of my string trimmer and the warm weather last weekend I decided to install the new module. I drove the rover off the charging pad and to my driveway to install the module, shut the rover down, installed the trimmer, turned the rover back on (no issues), and used the app controller to test out the trimmer. I then told the rover to go back to the charging pad and it told me to drive back to a mapped area… which I found weird as it definitely should have already been in a mapped area. So I drove the rover over to in front of the charging pad and tried again and got the same message…. The rover was here:

Yet the map shows it here….

Figuring that maybe putting the charger on the pad and actually starting the charge cycle my help, I moved the rover here:

Started the charge cycle:

Yet the map STILL shows it here:

Despite being here with the red x indicating the location on the map:

I‘ve also tried doing the map drive correction and it made no difference.

I mean, being off by a few inches or even feet I could see described as “Map Drift”, but this is being off by like 20 feet. Is this actually a map drift issue or do I need to make a support ticket? I would really like to not have to re-map everything considering the last time it took me almost 4 hours and two or three charge cycles.

I’m not seeing green GPS. Map drift correction needs ideal conditions to correct for. What does your current diagnostics look like while it’s on the dock and charging? Where is your Yarbo on the map when it’s docked at the time you take the diagnostics screenshot? Please include RTK, Status, Data Center, and HaLow sections. Also hit the Yellow details afterwards and connect to your DC and post the CNR values screenshot too.

The GPS almost never goes green when it’s on the charger. There’s just too many trees around. For me to get a solid green consistently, I’d have to put the pad 10-15 feet out into the middle of the yard, and that’s not happening. The pad location has remained unchanged since last summer and was still good until the day I installed the trimmer.

I’ll have to get the diagnostic info when I get home this evening. I just don’t see how the map just shifted between boot cycles like that….

Yeah that shouldn’t happen but if you did correct map drift and conditions weren’t right, it could definitely shift your map.

No the shift had already taken place. I tried the map correction afterwards, and it did nothing. The map and the rover’s indicated location didn’t change at all.

Againg the steps were:

  1. Map indicated just fine.
  2. Drove the rover off the charger to my driveway
  3. Shutdown the rover
  4. Installed the trimmer module
  5. Turned the rover back on.
  6. Confirmed the module showed in the app.
  7. Manually drove the rover to a patch of grass
  8. Turned on the trimmer and drove the rover over it to ensure the trimmer was working properly.
  9. Turned off the trimmer.
  10. Hit the Charge button in the app controller
  11. Got the warning message to drive the rover back inside a mapped area.
  12. Drove the rover to directly in front of the charger
  13. Hit the charge button and got the same error
  14. Checked the map and saw the position was off by 20 feet.
  15. Manually parked the rover on the charge pad
  16. Initiated charge mode, which seems to have succeeded.
  17. Checked map again, still wrong position.
  18. Tried doing Map Drift Correction, which appears to have had no effect.

You could try restoring from a saved map but that will wipe settings, work plans and schedules. Otherwise I’d suggest a ticket to see if they can diagnose it.

Hi there, as Bryan suggested, we recommend submitting a support ticket so the team can investigate this further, especially if the initial troubleshooting steps have not helped.

So, I tried to access the Details page on the diagnostics view, and got this screen:

Even after several minutes of waiting, the screen did not go away. I tried to go to the Data Center Settings page and got the same screen that would not go away.

I tried removing power from the Data Center and turning it back on, and saw no change.

I’m assuming at this point I really need to put in a support ticket.

While not explicitly explained, this is a short range Bluetooth connection

Yeah, if you were right next to the Data Center and your phone was unable to locate it, I guess it’s time to open a ticket. Hopefully Yarbo support will get things resolved quickly for you.

I would. This isn’t uncommon for some DC’s, unfortunately. You have to get extremely close for some. Almost touching.

Ya… I’ve done this connection several times before and have been able to connect from 30-40 feet away with ease. It’s weird that it doesn’t seem to want to connect at all now…

Yep. Very weird. And frustrating for you I’m sure.

There might be a new DC in your future. Could be the culprit.

Try removing the trimmer and se if the map will let it go back to the charger.

I had a problem with my trimmer not letting the core work I removed it and it works great.

Thay sent me a replacement trimer and now all is great.

Interesting. Were there any other symptoms? Did you have map drift?

Hi there, this may require further investigation from our support team. Please feel free to submit a support ticket when you have time.

I’ll give that a try this weekend. It’s supposed to finally be warm again… at least until Monday.

After I try removing the trimmer and rebooting the rover as Harold suggested, if that doesn’t solve the issue I’ll definitely create a support ticket. The Data Center not being able to connect to the app definitely has me concerned.

It starts to go and stops and gets an

Do you recall what the error was?
