I’ve been watching my Yarbo tear up my lawn. It seems that when an obstacle is detected the unit abruptly stops and reverses direction,also abruptly. When navigating around trees or in shady areas where the ground is likely to be damp and root systems for grass are weaker, this rips up the grass and even leaves divits.
Can this maneuver be made less abrupt? Maybe make the level of aggressiveness user selectable

Out of curiosity, what speed are you running at? I use slowest and find it to be more responsive with better reaction times. Anything above that it and it will certainly abruptly stop once it detects something.
I think this is a legitimate concern.
I run my Yarbo at the fastest speed and can confirm it’s avoidance motions are very abrupt at times and not kind to the grass.
My grass is tough, and is a country lawn, not city grass, so my grass can handle this and my 70hp tractor driving on it, but I can see if you have very nice grass this can be a concern. Also to the life of the core it can’t be good doing harsh movements, it could just coast to the stop at some point instead of putting the brakes on like it does.
It has brakes?
Mine is ramming trees, posts and stones in full speed it is set on. I do run it on medium speed. Haven’t tried anything quicker for a long time. Collisions in medium speed look serious enough
Not really brakes, but abrupt stops by stopping the motor, electric braking.
It does not, as B-Mod mentioned, it just does electrical braking. When it does this, especially with high speeds, the rear of the core actually lifts up a little and a lot of the weight shifts onto the front wheels.
If yours is not slowing down, then you may have disabled vision (M1) or ultrasonics (MPro) and then it will not execute the “Gentle” in “Gentle Contact” because there is nothing to alert it to slow down before bumping. And yes, I’m sure you disabled these for other reasons, so it’s a choice of what is the best choice to achieve the end goal most effectively.
You’re right, I set the slower one too and it works really well.
As usual I was a bit sarcastic
Hi there, thanks for sharing your suggestion. If more users raise the same concern, I’ll help pass this feedback along to our product team for further consideration.
Mine still slows down to a crawl, until it’s a couple inches away, then floors it for the actual impact, lol. I notice it mostly on my wellhead and stack vent. It’s as if their distance calc is off by two inches.
Yep. I’ve watched it do this with objects as well. Slows down until it’s an inch away then speeds up into it. Tickets are worthless at this point.
It’s not a bug, it’s a feature!!
Demolition Derby mode!! 
The prelude to the attack? 
Wonder if it is intentional so it registers the contact more effectively?
And they can sell more bumpers later.
Then why bother slowing down at all
Thrill of the hunt? 
In all seriousness, I don’t recall seeing this slow down then speed up. I’ll have to pay attention next time to see if it does. I’m wondering if it isn’t intentional, if it’s getting close enough to the object that the camera becomes “blocked” and then it overrides the view and speeds up as a result.
In Gentle Contact it does what it’s supposed to, just not quite long enough like @steve noted.
@steve @cobradunn Sorry for the inconvenience. I’ve shared this feedback with our product team for further review and optimization.
