Been using my new mower pro and definitely find gentle contact to be the most effective setting for obstacle avoidance. Unfortunately, it’s really not all that gentle and I had yarbo once wedge himself under stairs and then at times start rolling over 70lbs rocks lol. It seems a little less than gentle. Any way we can get a setting that’s a much more softer contact - I think that would work great.

It is actually pretty gentle. The issue is that it needs to hit the object directly on the bumper. Normally when it does that, it is pretty good at recognizing it, even using vision to slow down near anything it detects. In fact, if there was an “Aggressive Contact” setting, I would use that in certain areas where there are only hard trees, and with all the “gentleness” it seems to take forever in that area.

Maybe I have a defective bumber because this has not been my experience. Sometimes it hits stuff and immediately stops, other times it keeps pushing forward. One time I was standing in the yard and it came up from behind me, hit the back of my leg and kept moving forward while crawling up my leg, it would not stop. This is my concern with HAVING to use gentle contact, which doesn’t always work in my case, because I have a lot of children around and they are very curious about the bot. The snow blower is really good at detecting people, announcing it and stopping.

Is it hitting in the corners? Those take A LOT of pressure to trigger there.

When it crawled up the back of my leg it was almost dead center. Since you brought up the bumber corners. My issue with the back of the bumpers is that if it hits the back of the bumper while backing up you still can’t drive it forward. You have to manually move the bot. This really needs to get addressed.

Hmm. That should’ve been registered more easily. Yes manual control should allow you to override. I get it stopping movement when it registers a collision, but let me clear it and move it in any direction to recover.

Interesting.
With the M1, “Gentle Contact” with vision enabled means it slows down as it nears an object, until it is about four inches away from from that object. At that point, it accelerates to normal working-speed and then the bumper slams into the object.
Yours remains slow until it actually hits?

I’m betting in that situation it just lost sight of the object and resumed normal speed?

I don’t believe so?
Wellheads, septic vents, trees, trailer jack…
Sneaks right up to them, then BAM lol

To be honest, I wasn’t paying as much attention to the M1 behavior. But with the Pro, the heavily wooded area takes forever as it crawls around and between each and every tree.

If the object has a “slanted side” the bumper may be “shielded” by the top of the mower. Little Tikes plastic tug boat has slanted walls and Yarbo tries to push that tug boat all over the yard.

Yarbo is modular. It’s just trying to take the tug boats job too! 
There’s got to be accelerometer data that can be used for determining contact right? Not just relying on bumper activations? I’m not even talking about anything resembling gentle contact, I just want it to not be at risk of breaking my stairs, rolling around heavy rocks, etc. Even a pretty damn conservative accelerometer threshold to detect a potential collision would prevent this. Yarbo sometimes hits the stuff like someone brought him to a rage room

I have few Luba 2 mowers and I have to be careful using Yarbo while they’re out mowing. In a few occasions Yarbo tried to run them over and had to be intervened. It was like robowars.

Michigan robots on YouTube had a show down with one. Yarbo won.

I’ve had a few really close calls between my Luba 2’s and Yarbo but thankfully no collisions yet. I’ve had to run outside and quickly stop one or the other to avoid impending impacts multiple times though. Obviously totally user error on my part.

Hi there, thanks for sharing your feedback. At the moment, we don’t have plans to introduce a softer contact setting, and it may not be considered in the short term. We truly appreciate your understanding!
