deadends are not accurate

Beware of deadends into sensitive areas. Mine backed off course and pushed my heat pump off its pad. It mowed that path successfully at least once before. I was hoping Yarbo could handle this trouble-spot, but alas, it cannot be trusted in such tight areas.


Most Deadends work OK for me, but there are one or two that ALWAYS see the mower head bash into something next to it – not bad, and then it straightens itself out (mostly). If I run them a 2nd time, they’ll be OK usually. There are one or two Deadends that “mostly” follow what I mapped but are kinda off. I agree these can use a little work.

I’ve not had one knock a heat pump off its pad, though. Hmm…Marketing will say that shows how strong the rover is!

I don’t know what to suggest, other than to really keep a buffer, maybe try re-mapping – although I have re-mapped, and those two whacky Deadends continue to whack what they whack.

Dead-ends really depend on the terrain.
Especially small slopes and grades.
If a wall has a grade that slopes downward, the M1 will slightly clock downhill and the core will track away from the wall when moving forward.
But going backwards, the M1 will again clock downhill and the core will track into, and sometimes up, the wall.
Setting dead-end speed to slowest does seem to help a little.

For DEs where hitting something is high risk, I’ve made it a habit to put them into their own task that I’ll manually trigger, so that I can supervise it.

HTH!

Is the dead end part of a mapped work area or outside of any mapped work areas? This makes a huge difference. If inside of a mapped area, when backing Yarbo assumes it has the right of way to use the whole area to maneuver. This can lead to unintended consequences the user didn’t anticipate for. Also, the entrance for the DE should be far away from any obstacles so it has a lot of room to maneuver to get into the dead end and then keep them as straight as you can between the tight areas to it doesn’t have to turn. You want this in case there are GPS multi path issues because of all the structures and metal there. I would also make sure that the rear of the core is going downhill when it’s backing so it doesn’t run into any issues raising up going up the hill.

That path is on a slight incline and it is mostly outside the mapped area. Good idea setting it on very slow. Yarbo executed the heat pump deadend perfectly the next day with me watching. However it failed miserably on a nearby deadend along some steps at the edge of the same map. That time I was there to hit the E-stop because it was still trying to back in the completely wrong direction. It was supposed to be trimming along the steps.

@JayWozz has a lot of experience with dead ends. Maybe he has some suggestions.
