I have saved some flight data using rosbag record, but the header of my topic /odom doesn't contain the time. When I extract the data using rostopic echo -b foo.bag -p /odom > odom.csv, the column %time is always 0. I was wondering how can the rosbag and rxbag can synchronize the data... I would like to know the mechanic and how I can get the rosbag time to associate it with the data. |

| 2015-07-21 14:27:03 -0500 | commented answer | How to change rosbag record rate - how to undersample messages Thats what I think also. I think that it should be a good tool to have. I supose this is not possible since if you broadcast back the bag in the system, it would not have the right rate. |
| 2015-07-21 13:01:14 -0500 | asked a question | How to change rosbag record rate - how to undersample messages Hi, I am running a complex system on ROS using an Asctec Pelican multirotor helicopter. I have node runing on the Asctec Atom Board and on ground station computers. The system transfert data over wifi. I have a multitude of message that I will want to record using rosbag. Many messages such as /pose and /imu are at 250hz for control purpose. Using rosbag to record this data is kind of CPU heavy. Since I am not required to record the data at the computed rate (250hz) for display my results, is there a way to tell rosbag to record the data at a lower rate; is there a way to undersample the data ? Best regards, |

So some of the nodes (such as rqt_pluggins and other GCS nodes) doesn't need to be compiled on the UAV computer. My question is this, how to tell catkin make to ignore those package automaticly (yes I am aware of the command catkin_make -DCATKIN_BLACKLIST_PACKAGES="foo;bar" but it is not very usefull if i want to ignore 2 or more nodes) Best regards, |
