2017-03-17 00:56:54 -0500 | asked a question | Can I record the data of the latest several seconds to a .bag? Hi, I would like to record the data of the latest several seconds, but do not find any way to do that. I think that what I need is a queue. Say, a topic of 1 hz, and I want to record the latest three seconds. The first three seconds are pushed to the queue. When the time stamp is larger than three, the data in the head is pulled, and the new data is pushed. I do not know if I am right. Or, is there any easy way to do that? Many thanks. |

2014-03-03 02:34:53 -0500 | asked a question | No Data from MAVLink_ROS Hi, I plan to use MAVLink-ROS to read the IMU data from APM2.5. Although it compiles sucessfully by rosmake, the data cannot be received. I use rqt_graph to check the topic and node, but there is no topic or node connected to the node "MAVLink_ros". As a beginner to ROS and Linus, I do not know how to solve the issue. My Ubuntu version is 12.10 and ROS is Hydro. Many thnaks. |
