Firmware 3.9.10 & App 3.15.3-Release Notes

It is. This is how they mitigated the issue for now. It will also pick up speed going uphill to keep the forward momentum.

This is related to the optimization on the slope mowing algorithm. When the rover detects slopes, it will slow down based on the slope angle it detects. The steeper the slope, the slower the speed.

Hello @Yarbo , today I got the latest firmware update. When I start my plan it came out of the docking station and immediately went back to charge stating your vehicle parking position is blocking Yarbo path. Actually there is no vehicle parked in the pathway. What could cause this issue? Attached the picture for reference

PS: I posted in two different places. Not sure where to post. Still learning how to use this forum


Adding the other image shows the vehicle park message.

FYI.. when I send it for the second time it didn’t complains. Not sure why it did for the very first time after the upgrades completed. Just want to bring it to your attention.

@steve - I just posted this on FB. Not sure it’s the new firmware, but I’m not the only one who “suddenly” ran into these issues, per some posts on FB. Ticket open. The rover’s mowing for now after kicking it, thankfully.


Issue: GPS takes longer to “go green”; Rover stopped in the middle of the yard while doing a Work Plan, can’t resume or recharge (can do Smart Vision)

UPDATE: Power cycled the Data Center, rebooted the rover through the App, I was able to resume the Work Plan.

I’ve seen the following reported out here, now I’m an experiencer:

  • GPS issues where Heading/HeadingDop/HaLow are great but Status stays 5 and AdjustAngle -1 or -2, and the GPS icon never goes green or takes longer to do so.

  • The rover stopping in the middle of a Work Plan somewhere in the yard.

Work Plan won’t resume. Diagnostics look fantastic, green GPS and HaLow. Can move the rover with Smart Vision, so it’s responsive. Cannot resume the Work Plan, and it won’t do anything on Recharge.

I do have the updated firmware and app.

Did have some GPS issues in that location that required me to move the rover a bit further than usual to finally get the green GPS icon. I don’t think I’ve had to move it quite so far and have it quite so open before to restore GPS, not where I was mowing.

The rover was out most of the day yesterday mowing, no stoppage issue. Today not so much.

Ticket #95381

Yep, I’m going to go check the usual stuff and see if I can get this going.

I thought I’d post this because others have reported it as well, so it’s not unique to me. Support has been notified!

I get the suspicion that AdjustAngle is being kept at -2 as a byproduct of keeping the core out of no-go zones and within boundaries. Someone, wrongly, had them throw in a test that simply cannot be satisfied. It might be a legacy test from the S1 that is not appropriate for the other modules.

Bonus points if we can syslog ALL the diagnostics to the address of our choice so we can plot DOP, GPS quality, motor loads, temps, battery current, collisions, track slips, everything on our own stuff, and adapt our maps accordingly, and even moreso, figure out and avoid the adjustangle logic error. PostGIS on a Pi would rock that, all day long.
