How to save and load a PRM map

s265452 commented 2 years ago

Description

Hi everyone, I'm using a Kinova Jaco2 mod. j2s7s300 ROS Melodic 18.04

I wish to save and load a PRMstar map, so I wrote something like this into ompl_planning.yaml:

PersistentPRMstar: # use this with a representative environment to create a roadmap type: geometric::PRMstar multi_query_planning_enabled: true store_planner_data: true load_planner_data: false planner_data_path: /tmp/roadmap.graph enforce_joint_model_state_space: true SemiPersistentPRMstar: # reuses roadmap during lifetime of node but doesn't save/load roadmap to/from disk type: geometric::PRMstar multi_query_planning_enabled: true store_planner_data: false load_planner_data: true planner_data_path: /tmp/roadmap.graph enforce_joint_model_state_space: true

But when I use SemiPersistentPRMstar planner, it generate a new roadmap everytime.

How can I fix this problem?

Hi @s265452,

Just to get it out of the way : Is the file correctly indented?

When using PersistentPRMStar, is the planner data correctly created in /tmp/roadmap.graph? When using SemiPersistentPRMstar, does /tmp/roadmap.graph exist? When launching the driver, or when using the planners, do you see any error message?

From what I see, it looks good, however I cannot test it on my side at the moment.

Regards, Felix

No. If I go in the tmp folder

/Computer/tmp/

I don't find the file roadmap.graph

When I use SemiPersistentPRMStar I read:

Does the /tmp/ folder exist?

Also, since it is in the root directory, moveit might not have the permission to write files in there. I would suggest to create a folder in your user directory (e.g. /home/<user>/tmp/) and use this folder instead.

planner_data_path: /home/<user>/tmp/roadmap.graph

After that, check if a file is correctly created when you use PersistentPRMstar

s265452 commented 2 years ago

Thank you for your support but It's the same. No file created in the folder

planner_data_path: /home/francesco/tmp/roadmap.graph

felixmaisonneuve commented 2 years ago

This file seems pretty sensitive to the format, I would try to put PersistentPRMstar at the top (before SBLkConfigDefault) and try again to see if it creates a graph file.

I would also try different combinaisons in the parameters order (e.g. type->enforce_joint_model_state_space->multi_query_planning_enabled->planner_data_path->store_planner_data->load_planner_data).

I cannot test right now and I find it very frustrating. If the issue is not resolved by then, I will try to test on an arm later this week,

s265452 commented 2 years ago

I did your modification but the problem still persists.

Is it possible that when I launchj2s7s300_virtual_robot_demo.launch I have to specify db:=true?

Even if I launch:

roslaunch j2s7s300_moveit_config j2s7s300_virtual_robot_demo.launch robotType:=j2s7s300 db:=true

I have this error

felixmaisonneuve commented 2 years ago

This is very possible.

Do you have the correct packages installed? sudo apt-get install ros-noetic-warehouse-ros-mongo

After, according MoveIt documentation on Warehouse, you will need to add this line in kinova_moveit/robot_configs/j2s7s300_moveit_config/launch/warehouse_settings.launch.xml

  <param name="warehouse_plugin" value="warehouse_ros_mongo::MongoDatabaseConnection"

This line already exists in the j2s6s300 config, but not on the other robot configs https://github.com/Kinovarobotics/kinova-ros/blob/93f66822ec073827eac5de59ebc2a3c5f06bf17f/kinova_moveit/robot_configs/j2s6s300_moveit_config/launch/warehouse_settings.launch.xml#L14

If it works, I will update the repo to add this line in all of our configs.

Start with this and let me know how it goes

Best, Felix

s265452 commented 2 years ago

I did these modifications and I've correctly installed the package sudo apt-get install ros-melodic-warehouse-ros-mongo

The problem still persists.

This is my kinova_moveit/robot_configs/j2s7s300_moveit_config/launch/warehouse_settings.launch.xml


<launch>

</launch>

felixmaisonneuve commented 2 years ago

Hi @s265452,

I did not forget you. I am doing some testing and found a couple of things :

In warehouse.launch, you need to change warehouse_ros to warehouse_ros_mongo

<node name="$(anon mongo_wrapper_ros)" cwd="ROS_HOME" type="mongo_wrapper_ros.py" pkg="warehouse_ros_mongo">

You need to add a dependency in your moveit config package.xml file. You will need to recompile with catkin_make after that.
```
<run_depend>warehouse_ros_mongo</run_depend> 
```
I have found this interesting PR (and the related issue) about these changes in moveit : https://github.com/ros-planning/moveit/pull/81/files
You need to install mongodb sudo apt install mongodb-server-core. Otherwise you will get errors that "mongod can't be found"

After all this, I can connect to the database (in the "Context" tab of the "Motion Planning" view in MoveIt) and save/load Scenes and States.

I created the branch bugfix/moveit-with-mongodb (based on noetic-devel) if you want to see the changes and experiment with it.

Try this and let me know how it goes.

Best, Felix

s265452 commented 2 years ago

Hi @felixmaisonneuve , Thanks for your advice.

I followed your tips but the problem still exists.

It seems that there are ''problems with the 'robot' element in the xml file''

When I launch

roslaunch j2s7s300_moveit_config j2s7s300_virtual_robot_demo.launch robotType:=j2s7s300 db:=true

felixmaisonneuve commented 2 years ago

This is weird, did you do any other moifications in the launch files except the ones I suggested? Can you copy your full output for

roslaunch j2s7s300_moveit_config j2s7s300_virtual_robot_demo.launch robotType:=j2s7s300 db:=true

Param /robot_description should be populated by the planing_context.launch, which is called directly in j2s7s300_virtual_robot_demo.launch https://github.com/Kinovarobotics/kinova-ros/blob/93f66822ec073827eac5de59ebc2a3c5f06bf17f/kinova_moveit/robot_configs/j2s7s300_moveit_config/launch/j2s7s300_virtual_robot_demo.launch#L16-L18

This seems to me to be unrelated to the argument db:=true. Can you make sure roslaunch j2s7s300_moveit_config j2s7s300_virtual_robot_demo.launch robotType:=j2s7s300 is running properly?

s265452 commented 2 years ago

No, I didn't other modifications.

Hi @s265452,

I went and tried it on Ubuntu 18 with ROS Melodic. I did not get any errors. I was able to launch moveit with mogodb and connect my planner to it.

Can you make sure you are using the latest melodic-devel branch and you did not change any files except the one from your specific moveit config folder? You cannot use the bugfix/moveit-with-mongodb branch I created since it is based on the noetic-devel branch (and it won't work on ros melodic) Also, I would do a catkin_make to make sure everything is correctly compiled (even if this step is not required if you only change launch files).

Point is, I don't know why it is not working for you. I tried the exact steps I suggested on the same setup and everything is working fine.

To me, the errors you get make no sense with the modifications I suggested, so there must be something else.

Best, Felix

s265452 commented 2 years ago

HI @felixmaisonneuve, It seems that the problem was about in the warehouse_settings.launch.xml in the line code:

<param name="robot_description" command="$(find xacro)/xacro --inorder '$(find kinova_description)/urdf/j2s7s300.xacro'" />

Now, I'm able to launch:

roslaunch j2s7s300_moveit_config j2s7s300_virtual_robot_demo.launch robotType:=j2s7s300 db:=true

I can connect to the database (in the "Context" tab of the "Motion Planning" view in MoveIt) and save/load Scenes and States.

But I tried to save the roadmap moving the folder into the catkin_ws:

planner_configs:
  PersistentPRMstar: # use this with a representative environment to create a roadmap
    type: geometric::PRMstar
    multi_query_planning_enabled: true
    store_planner_data: true
    load_planner_data: false
    planner_data_path: /home/francesco/catkin_ws/tmp/roadmap.graph
  PersistentPRM: # use this to load a previously created roadmap
    type: geometric::PRM
    multi_query_planning_enabled: true
    store_planner_data: false
    load_planner_data: true
    planner_data_path: /home/francesco/catkin_ws/tmp/roadmap.graph

It doesn't save the roadmap.

You are able to save a file roadmap.graph ?

felixmaisonneuve commented 2 years ago

Yes.

If I choose the PersistentPRMstar and move the arm in moveit, once I close the ros driver (CTRL+c in the terminal where you lauched roslaunch j2s7s300_moveit_config...), the file roadmap.graph will be created. You do not need to be connected to the database for this to work.

s265452 commented 2 years ago

I followed your instructions but I don't know why, it doesn't work.

felixmaisonneuve commented 2 years ago

What version of OMPL planner are you using? According to OMPL planner documentation, you need at least version 1.5 for this to work.

Note that saving and loading roadmaps is only available in OMPL 1.5.0 and newer.

You can find your version using apt-cache policy ros-melodic-ompl

I am using ros noetic with ompl version 1.5.2 (the most recent one)

s265452 commented 2 years ago

Well, you found the problem.

My version is 1.4.2-5bionic.20191212.045602

How can I install the new version?

I did

chmod u+x install-ompl-ubuntu.sh

./install-ompl-ubuntu.sh

apt-cache policy ros-melodic-ompl
ros-melodic-ompl:
  Installato: 1.4.2-5bionic.20191212.045602
  Candidato:  1.4.2-5bionic.20191212.045602

        100 /var/lib/dpkg/status

felixmaisonneuve commented 2 years ago

I don't know if the version 1.5 of the package is available on ros melodic.

maybe sudo apt-get update && sudo apt-get upgrade or sudo apt-get --reinstall install ros-melodic-ompl? If 1.4.2 is the most recent version for ros melodic on ubuntu 18, I don't know what you could do. I don't see anywhere on the moveit doc that it is, but I don't see anywhere that it isn't either.

felixmaisonneuve commented 2 years ago

Hi @s265452,

I will close this issue since I don't think I can provide any more help. If you have another question, feel free to comment/re-open this issue or open a new one

Best, Felix

hello @felixmaisonneuve

I have ompl version 1.5.2. For some reason I am not able to save a roadmap.graph file. I chose the PRMstarLoadStore and the PersistentLazyPRMstar planner in RViz in Motion Planning window, and also tried changing the path to where the roadmap.graph gets saved, from /tmp to /home/<USER>/tmp. Could you lease help me with this?
