Planner Unable to create plan in case of wide obstacles

[shubham-shahh]

Hi,
I was trying to run the planner in an environment with wide obstacles
I have set <arg name="virtual_ceil" value="4.5" />

here's how the obstacle actually looks

when I am trying to plan a path with a goal on the other side of the obstacle, the planner is unable to make a plan. and I am constantly getting warnings
[ WARN] [1676632376.780805656, 1023.498000000]: Failed in A star path searching !!! 0.2 seconds time limit exceeded. [ WARN] [1676632376.780850817, 1023.498000000]: A-star error, force return!
do I need to change something to avoid such obstacles?

this is the grid map view of the obstacle

thanks

@bigsuperZZZX, any update on this?

ego-planner is a local planner which only considers near obstacle avoidance.
In your case, a high-level navigator that guides ego-planner by giving local goals is necessary.

I see, do you have any quick references on top of your mind which i can refer?

Thanks
