Yes I need to convert the pose of the object between the frames, not the robot, but I don't know how, your solution is n

I found the problem and it's because you need to sum the base_link_to_odom_tf vector to the pos_x and pos_y vector in or

Sorry for the ignorance but I don't see Gazebo anywhere in that tree

Hi guys, I have a node that publishes a MarkerArray Topic:

ros::Publisher obst_pub = nh.advertise<visualization_msgs::MarkerArray>("/obstacles_markers", 1);

which contains my obstacles. Then I have another node that calculates the width of obstacles through the laser scanner and put it in a MarkerArray as well.

Now the problem is that I want to publish this new MarkerArray into the other existing topic "obstacles_markers", is that possible?

So I can define a topic in the other node with the same name of the first one and publish on it without having conflicts
