IMU stopped working

[sskorol]

IMU data is not published anymore.

Steps:

• run luxonis/rae-ros-robot:humble
• run either robot.launch.py or bringup.launch.py w/o LED node
• run ros2 topic echo /rae/imu/data

Expected: IMU data is published. Actual: there's no data at all.

Note that when I used the previous docker images, at least angular velocity and linear acceleration were published. On the other hand, IMU plugin didn't reflect any changes in robot's pose in RViz.

I will check if new changes broke anything for imu. Would you mind doing: fw_printenv

and pasting the output so I can quickly check if everything seems right there.

Sure, here's it:

That's the host OS output. If you meant container, then fw_printenv is not available there. I installed u-boot-tools, but the output was Configuration file wrong or corrupted.

Only EKF prints something related to IMU:

[ekf_node-3] X acceleration is being measured from IMU; X velocity control input is disabled
[ekf_node-3] use_control is set to true, but control_config has only false values. No control term will be used.

Here's the video from RViz. Note that a robot randomly moves left-right (virtually). But there was no physical interaction made or teleop ran. Then I moved it manually a little bit, but IMU marker obviously left in the same place, as there's no data received.

Could it be the result of the merging of the recent updates? As I believe that several days ago I haven't seen such behavior.

[danilo-pejovic]

Yea that is output for printenv I needed - everything seems ok there.

We are working on IMU related things right now but no changes recently pushed to humble should break the behavior.

Lets try one more thing. Can you add

imu:
      i_batch_report_threshold: 5
      i_max_batch_reports: 5
      i_enable_rotation: true
      i_message_type: IMU_WITH_MAG_SPLIT
      i_sync_method: COPY
      i_gyro_freq: 100
      i_acc_freq: 100
      i_rot_freq: 100

To your camera config at /ws/src/rae-ros/rae_camera/config/camera.yaml inside the container (you dont need to rebuild the package) as another sub category under ros_parameters. That should fix the issue.

Yeah, now I see the data published. But, RViz doesn't reflect IMU changes due to:

[INFO] [1697836266.854962595] [rviz]: Message Filter dropping message: frame 'rae_imu_frame' at time 1697746072.441 for reason 'the timestamp on the message is earlier than all the data in the transform cache'

Seems like it drops all the messages.

Note that I tried Cyclone DDS as well, but no luck.

[sskorol]

Also note that if I change the fixed frame in RViz to base_link, the IMU message drop errors disappear. However, the IMU marker is displayed flipped (z at the bottom). And of course it affects the map rendering. Anyway, I guess the sync issue happens somewhere on slam-toolbox level.
