Forgot to say, Ubuntu 14.04/Indigo
from imu_tools.
Could you record a rosbag of the data_raw topic please?

Here it is.
I moved from the initial pose, twice to one direction, and twice to the other direction, and finish at the same initial position.
from imu_tools.
With the following commands, I was able to run everything without problems:
$ roscore
$ rosparam set use_sim_time true
$ rosbag play --clock --loop 2015-09-24-23-58-09.bag
$ roslaunch imu.launch
This is the imu.launch I used:
<launch>
<!-- Nodelet manager -->
<node pkg="nodelet" type="nodelet" name="imu_manager"
args="manager" output="screen" />
<!-- IMU Orientation Filter -->
<node pkg="nodelet" type="nodelet" name="ImuFilterNodelet"
args="load imu_filter_madgwick/ImuFilterNodelet imu_manager"
output="screen">
<param name="use_magnetic_field_msg" value="false"/>
<param name="use_mag" value="false"/>
<param name="fixed_frame" value="odom" />
<param name="publish_tf" value="true" />
</node>
</launch>
The fixed_frame
and publish_tf
params are just for debug, so you can visualize the tf
topic in RViz (you need to set the RViz fixed frame to odom
). In a real system, you'd feed the /data/imu
topic into something like robot_pose_ekf
instead, which in turn would produce the proper tfs.
By the way, the messages in your bagfile have frame_id
"world"; this has to be the IMU frame, so it's a bit of a strange name for that.

Ok, I was launching similarly but without setting any parameter, i.e. using the default ones.
The only difference is that you explicitly set use_mag
parameter to false, and it is default to true here. I don't see how that can affect, but now it is working here as well.
Thanks @mintar, I'll close the issue.
