Today with the new yarbo lawnmower module first mow was a surprise as Yarbo was literally crawing with random bursts of set mowing speed (medium)
This video demonstrates it. It’s slow, then when doing a smart turn, it does it in normal speed and then ~ 1:50 randomly picks up set (Medium speed) and after that also wiggles couple of times.
Those rapid movements seemed to be at the end of the zig zag when it was turning around on the first pass. Is it on a slope at all over 5%? Hard to tell in the video. If it was, it was probably adaptive slope.
In video starting from 1:50 it did almost whole stripe in set speed.
And no - there is no slope at all. + Yarbo has been mowing the area several times already and always at set speed.
Basically it looks like yarbo was in it’s slow-down mode which it uses before the gentle contact. Not sure if obstacle is detected by camera or ultrasonic sensors.
However in app no red spots appeared.
So either way Yarbo was ready for conact with something only Yarbo saw in front and it wasn’t there.
Only notifications about blocked left or right cameras. But as far as I understand they are not used in obstacle deteciton when mowing.
Additionally - with previous mower module everything was working perfect with all vision settings I have. This issue appeared when I put on the new mower module which was sent to replace old one which had the “adjusting blades” issue and dead blade height adjustment.
So definetely there is something wrong with the new mower module. Hopefully that can be addressed with software fix and won’t require shipping of new mower module again.
I don’t think this is a hardware issue. Only software. Have you pulled the battery cable for 5 mins and reconnected/booted to see if that clears it up?
Not yet. I powered off the Yarbo, connected the module and that’s it. Now it’s working all the time not to let grass overgrow.
Most probably will have to do the battery voodoo thing, but nevertheless looking forward what support guys have to say about this. They should be able to tell from logs what exactly is causing the crawling.
P.S. - same is also in dry grass when there is no moisture coming up from the mower module.
P.S.S. - was mowing the same areas even in rain with no issues with my previous mower module.
Tomorrow I could try to put back the original ones and see if it makes any difference, however I can’t figure out ANY logical explanation how antennas could affect the Yarbo’s behavior using vision … unless they are emitting something which interferes with ultrasonic sensors
Understood. That value is normal for the M1. It’s sure looks to be behaving like it’s in Gentle Contact mode when vision sees something. I’m with @bryan.wheeler on the battery disconnect and full reboot.
Disconnected the battery for one and a half hours. Kept power button pressed for a minute without battery.
Unfortunately none of that made any difference nor solved the issue.
