Inconsistent mowing speed?

Has anyone else noticed their yarbo just creeping along? I noticed it a week or so ago where it’ll be mowing and it just starts going very slow. With the M1P I increased my mow speed to fast it does great cutting at that speed, I just can’t figure out why all the sudden it’s doing this slow creep mode. It’ll do it while out in the middle with nothing around it so I don’t think it’s sensing obstructions. The app sure doesn’t say it is, no red marks or messages.

The last couple of days I’ve had it out working on the hay field and it does the creep movement then it’ll surge to the right speed then slow down again. I thought maybe the tall grass was causing it, again no red marks no messages I even made the entire area a no vision area and it still does it. I have a couple videos but the forum upload size limit won’t let me upload them. I’ll try and get them uploaded to YouTube tomorrow and link them.

If anyone has ideas happy to try them out.

Couple of things. If it’s in gentle contact mode and it’s sensing something (tall grass), it will slow down to “contact it gently”. Or it could be slope mode. I don’t think it takes much of a slope for it to kick in.

Hmm good call on the gentle contact. I was running the field in that mode because I didn’t want it seeing ghosts with the tall grass. But now that I have it all under a no vision I’ll switch it and give it a try.

Does the no vision box not work when traveling to the start point? I switch from gentle contact to moderate bypass. Sent it out and now it just see obstacles everywhere it turns. It’s just tall grass.

The blue is the no vision.

Well even when it got to where it was supposed to start mowing, I manually drove it there. It still is seeing obstacles and it’s showing it’s in vision bypass status.

It’s way worse now than it was just going slow.

The no vision box does not seem to matter. The pro head isn’t supposed to be using the ultrasonic sensors yet? Correct?

The pro does use the ultrasonics. The M1 hasn’t reenabled them yet. It might be detecting the tall grass. Obviously, once you cut it down it shouldn’t be an issue.

As Bryan mentioned, Mower Pro uses ultrasonic sensors, and tall grass can sometimes trigger false obstacle detections, which makes the unit slow down or “creep.” We’re actively training our vision segmentation model to improve Yarbo’s obstacle recognition and reduce false detections.

It is for sure the ultrasonic sensors on the pro causing issues. You can turn them off on the toggle switch in the app.

Point me to where to turn them off? Not finding a setting for ultrasonic sensors.

Was wondering that myself. I’m only aware you can disable that in pathways. You used to be able to disable it in areas, but no longer.

Do we know what causes the “creep” speed? I haven’t found a pattern, it seems to do it occasionally in wide open areas with nothing but grass all around.

Just slopes and perceived object are the two things I’m aware of that will cause that.

It looks like you can only disable it on pathways. I’m seeing the same strange behavior, despite disabling it for all pathways. I’ve set mowing speed to “fast” but it’s going slower than even “medium”.

My wild guess is that some (loud) people were complaining so much about Yarbo getting anywhere near obstacles, and missing things on inclines, that the software has swung too much in the opposite direction. Now it sees things everywhere and goes slow so often, and there’s no way to turn all these off.

Like you, I have a yard that needs no obstacle avoidance…at all! Let ‘er rip. If it hits a tree, go around. Otherwise, stop detecting and stop slowing down. If there’s an area that needs special care, it would be nice to set just that one area, but 90% of the time, gentle (or vigorous) contact is fine :roll_eyes:

Serious question: Can I put tape on the sensors to disable this for now?

Perceived objects count during gentle contact?

Worth a shot but it might perceive that as an obstacle.

It uses cameras and or ultrasonics to detect when it’s going to hit something and slows down.

Yeah I watched it today in my back yard it’s been cutting all summer. Middle of the yard nothing around it. Grass normal height flat no slopes and it just creeps for 100 feet. Turns next path right next to the previous path and mows normal speed the whole way. Doesn’t make any sense.

Yarbo has been mowing all summer I don’t think I’ve seen it doing this before. Only difference is the now I’m using the pro head. And I haven’t gotten to mow with it a ton since it arrived given everything is brown since it hasn’t really rained in weeks.

I have all my areas set to gental contact but it’s got to still be using the cameras and probably the ultrasonic sensors. I watched it slow down as it approached a tree before bumping it, which is fine. But if the ultrasonic sensors are seeing ghosts like the cameras do, shut them off.

I even gave yabo a bath to see if maybe dirty camera and sensors were causing the issue but it didn’t seem to help.

Also something new while it was mowing, (I may make another post) but I noticed my downspout was missing, went looking for it and yarbo ran it over and apparently to hide it’s poor decisions it drug is over 50 feet around two corners to the other end of the barn. Finally found it all torn up.

same here. pro has more sensory overload :thinking:
