I am facing this error when I try to launch my pose3D.launch node :> [ERROR] [1537274177.574505613]: Client> [/pose3D] wants topic /odo to have> datatype/md5sum> [interval_map_msg/odo/18550ae0562d2d3f5ac16bd524fd7ee4],> but our version has> [motion_common_msg/Odometry/53fb859e63296783fbcea5a91fdc0352].> Dropping connection.
I have a rosbag with a topic /vehicle/odometry, and the message type is supposed to be /interval_map_msg/odo. Has the error message say, I think my rosbag is sending the wrong type of message but when print the msg of my rosbag thanks to a python script i can clearly see this is the good type.
So I am guessing the msg of my rosbag has a type of msg has motion_common_msg/Odometry and even if interval_map_msg/odo msg type is the same, ros can't recognize it.
When i run the command line
> rostopic info /interval_map_msg/odo
I get the following :
> Type: motion_common_msg/Odometry>> Publishers: *> /rqt_gui_cpp_node_30580> (http://agoldstrich-Precision-7520:46015/)>> Subscribers: None
So indeed I need to change my topic type.
Is it possible to change it ? And how can I do that ?
