I'm having some hard time

[weicyingqiaopian]

Hello, thank you for answering this question, I would like to ask how to add this to the move_base

[ipa-rmb]

For C++ Implementation to move_base check this code:

ipa_coverage_planning/ipa_room_exploration/ros/src/room_exploration_action_server.cpp

Line 707 in f8a1dae

void RoomExplorationServer::navigateExplorationPath(const std::vector<geometry_msgs::Pose2D>& exploration_path,

and

ipa_coverage_planning/ipa_room_exploration/ros/src/room_exploration_action_server.cpp

Line 1037 in f8a1dae

bool RoomExplorationServer::publishNavigationGoal(const geometry_msgs::Pose2D& nav_goal, const std::string map_frame,

[weicyingqiaopian]

Thank you for your answer, what should I do now, do I need to write the client to use it?

[ipa-rmb]

I think if you interface to your robot with move base, you just need to configure the coverage planner accordingly and activate that you want the coverage planner to control your robot. You can set this paramter in the config file to true, to have this behaviour:

ipa_coverage_planning/ipa_room_exploration/ros/launch/room_exploration_action_server_params.yaml

Line 34 in f8a1dae

execute_path: false

[weicyingqiaopian]

I've changed the execute_path: false parameter, but it hasn't changed

[ipa-rmb]

Ok, and you started the coverage program from the sample action client, rigth? The sample action client overwrites the path execution setting to false via dynamic reconfigure:

ipa_coverage_planning/ipa_room_exploration/ros/src/room_exploration_action_client.cpp

Line 123 in f8a1dae

drc_exp.setConfig("execute_path", false);

I would suggest: have a look into the code of the sample action client and adapt it to your needs. It might even just load a predefined map from our test set right now, and not use your own map. It is just an example. You can also just write a brief python script with an according call to the ipe_room_exploration action server. Then you have full freedom.

[weicyingqiaopian]

Should I just change this to true?

[ipa-rmb]

This would be an option. Anyways, please understand that the sample client is majorly written for people without a robot attached, it just demonstrates coverage planning based on database maps. There might be more adaptations needed to run the robot. As said, please quickly scan the code of the sample client with your application purpose in mind.

[weicyingqiaopian]

Thank you, you are really responsible, thank you for helping me, I don't know how to write a client that can implement the coverage path planning navigation of my own map

[ipa-rmb]

One thing I saw, that will definitely need correction, is how you provide the map to the algorithm. In the client, these lines read the map from a file:

ipa_coverage_planning/ipa_room_exploration/ros/src/room_exploration_action_client.cpp

Line 68 in f8a1dae

else

[ipa-rmb]

The interface to the room exploration server is defined and explained here in this file:

ipa_coverage_planning/ipa_building_msgs/action/RoomExploration.action

Line 1 in f8a1dae

# Room Exploration action

[weicyingqiaopian]

Is there any example of client code?

[ipa-rmb]

Only the sample client you know in C++. Using this sample code and adapting it should be quite straightforward, it contains especially the ROS action call to the exploration server to start processing and optionally execute the trajectory following.
ipa_coverage_planning/ipa_room_exploration/ros/src/room_exploration_action_client.cpp

[weicyingqiaopian]

I'm going to test it later, I just changed that parameter to true and it already works, thank you

[weicyingqiaopian]

I'm going to bother you again.,Mine doesn't seem to have obstacle avoidance anymore.,What's the reason for this.

[ipa-foj]

What exactly do you mean? Our code only provides the navigation goals, the obstacle avoidance needs to be handled by your move base instance you set up for the robot.
