Anyone have their Yarbo just glitch out? I’ve had mine wander off its path in the middle of the lawn, sometimes it just rolls back and forth and burns holes in the lawn. I’ve had it go around “obstacles” even though there’s nothing there. It’ll randomly just do 360’s in place. More recently it’ll just drift 4-6 inches off the mapped plan, which is enough at times to just have it roll off a curb, never make it around a street sign post, drive into the fence, up the fence post, roll into the house, tilt off an edge separating an arborvitae from the lawn and drive straight into my tool shed. I’ve done the option to correct map drift, doesn’t seem to help much.

Correcting map drift when not required may have exacerbated your situation. Most times correcting map drift is actually not required and can be corrected by a reboot, moving the rover away from the docking station for a short time and then back on, or just waiting a while, although the Support KB leads you to take action immediately, unfortunately.
@Yarbo-Forum, can your team review the Support KB article https://support.yarbo.com/portal/en/kb/articles/2024-yarbo-position-misaligned-with-the-map to make sure folks aren’t taking actions that could result in re-centering their maps without a REAL need to do so? The fallout can be kinda bad.
But, YES, @sewnarine.durga, I’ve seen everything you’ve seen. My interpretations:
- Vision: Vision being on can cause the rover to go way out around invisible things. Try turning Obstacle Avoidance to Gentle Contact.
- “Dancing bug”: You mapped something and had the rover move backwards while doing so, even slightly. Yarbo should be fixing that. Until then, a workaround is to set Border Set Back to non-zero.
- 360s in place, wallowing: Generally while transitioning from Pathway to Pathway…or something. Aggravating when it can’t seem to make up its mind.
- Moving back and forth, indecisive, even with Vision OFF. Vision is always running and influencing the rover, and in my case it hates chicken wire (and other “obstacles”) near the Area, especially at corners. So if your rover is seeing anything, it can become very indecisive.
If your mowing is off by a few inches, it could have been the map drift correction that did it, sadly. I don’t know what to do there, other than re-map the items that are misbehaving. 
So I believe a lot of your behavior is not unique, and I know Yarbo has a high priority on dealing with these items. Perhaps @Yarbo-Forum can give us an update of what related bugfixes/changes are coming in Release 7?

This definitely sounds like some hooks or overlapped boundaries. There is also an IMU bug on some units where it does 360. A reboot or battery cable pull for a few mins resolves this. Fix for that should be next release they said.
A remap could help, but so could checking your map for pinched areas around NGZ’s and boundaries that the rover can’t navigate due to being too small. Checking for places where mapping you may have backed up. And also checking for path lines that go outside of boundaries or into NGZ’s. This can also cause issues like what you are describing and it’s usually a result of what I mention above. Boundary set back to at least 4 can typically resolve most of this.

Thanks to @bryan.wheeler and @Ken for providing such a detailed explanation of the possible causes. You can follow their suggestions to see if that helps resolve the issue.
If the problem persists, please feel free to submit a support ticket along with a brief description of the issue and an estimated timestamp. Our support team will be happy to look into it and help identify the root cause.
Also, just a quick note: Map Drift Correction should be used when the Yarbo’s position in the app doesn’t match its actual position in the real world.
Hope this helps, and don’t hesitate to reach out if you have any further questions!

Thank you everyone!!! I tried remapping and Yarbo was unable to calculate routes, when I get some time, I’ll try again. Since I posted the issue, it stopped. Go figure. lol. Now it’ll randomly beach itself off the sidewalk curb and I have to manhandle it back onto the sidewalk strip. I read somewhere that the “right” antenna is used for mapping, is there any truth to that?
Yarbo has been a gamechanger for me. My lawn looks amazing, it cuts everyday (weather permitting) and I’m down to 30 minutes of work instead of being out for 3-4 hours
Map calculation fail: You may be missing a Pathway. If you removed an Area and replaced it, the Pathways to/from and Deadends from that Area need to be re-created. No-go Zones (and maybe No-vision Zones?) will be OK.
Antennas: Map borders counterclockwise and No-go Zones clockwise. This keeps the dominant antenna toward the work.

Left antenna as you face the rear of the core is the primary. Right is for the angle and displaying the number of satellites in the diagnostics. Keep the left antenna towards the work area when mapping boundaries and NGZ’s. You could also say, keep the right antenna on the boundary line. Or if you like CCW and CW, go with that.

Ugh…Ayup, I had a bad typo in that response, @bryan.wheeler. Fixed. Thanks for pointing it out. Half asleep, as usual.

Another tidbit I wish I knew earlier. You guys are a great wealth of knowledge!
Thanks for sharing.
