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? 2021-03-29 09:08:42 -0500 received badge ● Scholar (source) 2021-03-28 15:20:57 -0500 commented answer Publish MarkerArray in an already existing Marker Topic Ok got it, I'm a totally beginner so thank you 2021-03-28 15:20:57 -0500 received badge ● Commentator 2021-03-28 12:45:24 -0500 commented answer Publish MarkerArray in an already existing Marker Topic 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 2021-03-28 12:44:44 -0500 commented answer Publish MarkerArray in an already existing Marker Topic So I can define a topic in the other node with the same name of the first one and publish on it without having conflitcs 2021-03-28 12:44:31 -0500 commented answer Publish MarkerArray in an already existing Marker Topic So I can define a topic in the other node with the same of the first one and publish on it without having conflitcs? 2021-03-28 10:30:33 -0500 asked a question Publish MarkerArray in an already existing Marker Topic Publish MarkerArray in an already existing Marker Topic Hi guys, I have a node that publishes a MarkerArray Topic: ros: 2021-03-10 04:17:22 -0500 received badge ● Notable Question (source) 2021-03-08 11:27:29 -0500 commented answer Extracting width from PointCloud data Thank you, I will try my best 2021-03-08 10:40:36 -0500 commented answer Extracting width from PointCloud data Thank you, I will do my best 2021-03-08 09:53:40 -0500 commented answer Extracting width from PointCloud data Thank you for the answer, that's exactly what I just did while waiting an answer.
