Are there any plans to help gps - with any trees it is absolutely horrible. I’ve rotated the rover antenna, the data center has a clear view but the yarbo STRUGGLES! There has got to be a way that it can handle minor lapses in gps better. Yarbo doesn’t travel that fast so it shouldn’t need full signal constantly to actually work.

They are working on improvements to their sensor fusion and more vision supported course corrections.
Yarbo needs at least 4 L2 satellites with a CNR of 37+ to be able to have cm level accuracy. It has to see the same L2 satellites as the DC for it to be able to use them. If it doesn’t see the same 4+ satellites, then it goes into RTK status 5 which is float mode. This is dm level accuracy and it will continue for about 30 seconds in those mode. It loses accuracy over time and distance traveled in float mode. Then it will pause and wait for enough common satellites to be stable enough to regain precision and then start back up. The hope is that this time and accuracy can be improved over future software updates.
Depending on your density, you can try speeding up the work plan speed to see if you can recover signal fast enough for it to not go into float mode or to get out of float and back to RTK status 4 quicker. This can be counterproductive if the areas have NGZ’s and other obstacles and it stays in float long enough to lose accuracy and potentially veer off path into these zones. So, I would recommend monitoring these areas and your diagnostics screen to see that you do not have these issues.

Yea +1, this has me feeling less than thrilled about my very expensive purchase.

Yarbo murdered a baby maple and went for some forsythias today. The rover thought it was where it wasn’t. A few minutes later it drove between two rocks and nearly into the road. Glad I was there babysitting. I shouldn’t have to be there babysitting, so, @ianwalter, I hear ya.
At least for me this is the exception and not the rule. But when it goes wrong after running into a poor GPS signal location under some tree canopy, it’s obvious that it can really go wrong.

Yea it doesnt make sense because I’ll move it like a foot and it regains “green” gps signal and continues so it seems like floating mode isn’t working at all and its not polling for signal properly. Mammotion RTK didn’t have this problem. I’ve never seen a “yellow/orange” gps signal, its always been none or green which is bizarre.
