uwv_kalman_filters::RotatedIMU

[bkocev]

Hi everyone,

where is uwv_kalman_filters::RotatedIMU defined? I cannot locate an orogen repository with similar name or so.

Thanks,
Bojan.

Hi Bojan,
this was a task to simulate a rotated IMU. You can safely remove this part from your test scripts.
But if you like I can also find and push this task to a branch.

[bkocev]

Hi Sascha,

thank you very much for your response.
Why did you need to rotate the IMU?
In case we decide to push this task to the repo, would it be a big problem to actually push it to the master branch, because I would like to use this branch?

Thanks,
Bojan.

[bkocev]

To speed things up, I would recommend that you push that task to the master branch. That should be fine. This would be the simplest solution for me. Then, I can decide whether to remove or not. :)

[bkocev]

One more argument why I think it would be better to push that task are the following two lines:

rotate_imu.connect_to orientation_estimator_min.imu_sensor_samples
rotate_imu.connect_to pose_estimation.imu_sensor_samples

i.e., I think you performed the evaluation on the rotated IMU samples. Therefore, it would be great if you could please push the task to the master repo. Thanks :)

While waiting for you to include the IMU rotation stuff, I temporarily disabled it and now I am getting this problem:

[saarnold]

The adcp_pose_estimation_scripts package is expected to be in slam/adcp_pose_estimation_scripts. This is why it doesn't find the right configurations and transformations.

[bkocev]

I just did:

mv navigation/adcp_pose_estimation_scripts slam/

and reverted my changes in adcp_pose_estimation_scripts/random_init_target_pose.rb and adcp_pose_estimation_scripts/common_startup.rb, i.e., replaced navigation/adcp_pose_estimation_scripts with slam/adcp_pose_estimation_scripts. I had already adapted the filepaths, but nevertheless I changed it to what you expect it to be. However, I still get the following error after running

[bkocev]

I think the problem is that you defined apriltag-related camera frames that are not part of the dataset and now they are missing upon loading the configuration. I tried adding

camera_frame: camera

in the default filter_config in slam/adcp_pose_estimation_scripts/config/uwv_kalman_filters::PoseEstimator.yml

but that did not help.

[bkocev]

I removed all the apriltag/camera related stuff. After that, I was able to run

ruby slam/adcp_pose_estimation_scripts/random_init_target_pose.rb

Three (Qt) windows pop up with titles:

1. random_init_target_pose.rb
2. LogControl
3. TaskInspector

However, when I try to play the log by pressing the green button in LogControl, I get the following error message:

[saarnold]

Yes you are right, there have been some changes to the task API that haven't been updated in the evaluation scripts.
I just updated it, let me know if it solves your problems.

[bkocev]

Hi Sascha,

        log_ports['depth_samples'].connect_to pose_estimation.pressure_sensor_samples, :type => :buffer, :size => 1000
        log_ports['depth_samples'].connect_to pose_estimation.altitude_samples, :type => :buffer, :size => 1000

The above change fixed the above "Corrupted logfile" error. Then after incorporating all of your changes into the forked repo local checkout in the rock_workspace of the rock-ros-bridge, I think I was able to run your scripts successfully :). These are some screenshots:

Visual Studio Code terminal output:

Note that I have not deleted uwv_kalman_filters::RotatedIMU.yml, but I think it is safely ignored.

Does the above look like a good sign? :)

Thank you very much for the efforts and overall support. :)

P.S. Now, I need to figure out how to update the forked version of your repo, because I had to fork it in our Mare-IT project because not all members have access you repo. I think in order to configure a pull from a mirror repo, I need a premium gitlab account. I check out what can be done.

Best,
Bojan.

[saarnold]

Yes that looks good 👍

You can have multiple remote repositories. That would be the easiest way of working with forks. See git remote add [remote_name] [git_url]

[bkocev]

I will then try adding your repo as a second repo. :)

Btw, is this a meaningful/expected output from "ruby slam/adcp_pose_estimation_scripts/random_init_target_pose.rb" :

?
