I was under the impression that Yarbo could work, at least temporarily, while under tree canopy utilizing some of the other onboard sensors. e.g., As long as it’s getting good GPS most of the time, it could operate in difficult areas using vision and wheel distance sensors.

I’m seeing that in places with reasonably open sky but next to a treeline that it sometimes looses GPS and then asks me to go move it into an open area before resuming. This interrupts mowing (and me) to go try to adjust it’s location and then it goes back where it was and starts again.
Are the any tips/tricks/settings that need to be adjusted for this to work like that?

We’re sorry to hear about the issue you’re experiencing. For areas where Yarbo loses GPS signal, you can set those locations as no-go zones to ensure smooth operation. We will continue to improve Yarbo’s performance in areas with weak GPS signals. Our long-term goal is to make Yarbo fully automatic with minimal human intervention. Thank you for your understanding!
There are no tips or tricks here. It can use the IMU and other sensors when GPS is poor or there is a loss or RTCM. Essentially there is a buffer of about 30 seconds and it loses accuracy over time and distance traveled. One day the hope is VSLAM will negate the need for GPS in these areas (and all over). For now, most of the time if you just wait, the rover will recover GPS on its own and continue on its way without any intervention from you. The message is a little misleading that you need to actually do something. Wait 15-20 mins at most and if it doesn’t recover on its own, drive it out to an open area and then hit resume. It should continue on and most likely will be able to continue past the last pause point.

Thanks Bryan. I think that makes sense and sets near term realistic expectations.
Making them no go-zones just means I’d need to manually mow. Hopefully VSLAM and other enhancements will come sooner rather than later.
