Imaginary obstructions

Yarbo is seeing things…

Yarbo is currently mowing my back west lawn. It’s fairly straight and level. However while mowing near a now go zone (near is subjective, its a couple passes away from the zone), Yarbo showed an obstruction on the map.

I paused Yarbo as there shouldn’t be anything there.

After walking out there, there was indeed nothing there.

I manually drove Yarbo right thru this imaginary obstruction. I didn’t even see tall grass.

I’d love to tell you what “obstacle avoidance” setting I have set, but that seems to be unavailable while mowing. I’m pretty sure its the default.

I can get that question answered in an estimated 11h and 41m. :wink:

Thoughts or suggestions?

and then the gear on the area you are mowing, to see what the present settings are.

If you change anything, it’ll pause the job and you’ll need to resume it.

Depending on settings, vision can be as sensitive as “anything not grass”. Or, at least it has in the past.

I’ve had birds on my lawn do this same thing. Also large leaves or debris.

Moderate Bypass.

Clean your cameras and it could have been direct sunlight in the lens or shading on the ground that was impacting its vision. If you have good no go zones and don’t expect any random things to show up, I’d say rely on the bumper with gentle contact mode and avoid vision for now.

Thanks for the advice.

Camera’s were cleaned at bath time (09:54 this morning). (Right cutting motor overheating.)

Yarbo was driving North. Time was 11:21 so sun was almost over head. Shadow maybe?

I’ll give gentle contact a go. I’d been hesitant to fiddle with it too much as this time of year it’s hard to keep up with the way the grass is growing.

Takes about 4 days to mow it all with the 8 inch overlap.

I hope the new firmware will be a little better at not missing spots so I can turn the overlap back down.

I too have been having this issue. I think it’s shadows but can’t always pinpoint it either. Does anyone know when there might be a firmware update? I know we want it tested but seems it would be good to get a few of the fixes in place.

Just curious - what travel speed and turn method do you use?

Currently using smart turns and fastest speed. I set the overlap to 8 inches for fewer missed spots. That really slowed things down. However the cut does look better.

Hopefully the new firmware will be more accurate on cutting and I can drop the overlap back down.

During those 4 days of mowing, there are times Yarbo is waiting on me to start the next work plan.

I’m always open to suggestions if you have any please pass them along.

Until the next firmware fixes the mowhawks, my only guess would be to minimize the number of areas that use smart-turn. Those things are minimum 40 seconds per lane, and they’re like watching my spouse try to parallel park. 7 minutes of turning per 10 lanes, at least.

For me, I use smart-turn depending on how soft the ground is, but the core can sometimes spend more time turning than it does mowing, lol. If the mowing angle makes a huge lane-count on a squishy day I’ll sometimes swap the turning mode mid-task when it is working a squishy part, or a hard pack part. But once perimeters become optional in the next FW, stuff like that can be made their own area, and smart-turns can be minimized. You’ll hopefully be able to reduce the overlap as well.

Thanks Steve for the suggestion. Switch to smart turns for the squishy areas. Good idea.

Zero turn does seem kind of rough on the grass over time. I have a bald spot in front of my charging station just like everyone else apparently.

Still need to build my pad I guess…

@Steve What’s your favorite turn style, aside of smart turn?

If the grass will handle it, U turn. For slopes, either smart or zero.

My favorite-favorite would be “don’t turn”, where the core just shoe-shines forward and reverse with no turns at all, lol. But that would need a rear bumper, or at least the rear cams to be used.
