Feature/gradient occupancy#66
Conversation
|
@nathanhhughes The old tsdf occupancy publisher broke when there were ramps and hills, causing some issues with the mid-level planner. I'm not sure if these changes are ready to be merged and how we should try that in the DCSIT system. So I thought it was best to pin you to get an idea. |

@MultyXu yeah, this will need some work on the Hydra side to actually merge in (it doesn't make sense to duplicate the code and work of the gradient-based traversability estimator), but easy to keep rebasing on top of develop if we have to make other changes to Hydra-Ros |

I think there's still too much duplication with the code and computation in Hydra and we should fix that before merging this

I think we should just add this as a sink to the traversability estimator instead of the reconstruction module (which would help drop the requirement for most of the code duplication), but we can also talk about what kind of architecture makes sense (we can also think about publishing this as a cost map instead of a occupancy grid and refining the mid-level planner to be able to take that as well)

Add a gradient-based map publisher for the mid-level planner and other functionalities.
