Re: Magnetometer
Oh I understand the magnetometer part now, thank you for the reply. Currently I am using the raw gyro readings, but I will try the orientation then. I am experimenting with your Mobile IO now and I am trying to create the best only-IMU odometry possible, then I will fuse it with the LIDAR data and w...

Magnetometer
Hello!
Do I understand it right, that the X-series do not contain magnetometer (so only 6dof)? I need that to calculate odometry from IMU, and currently the yaw has a horrible drift.
Thanks: Istvan

Re: Python accel_includes_gravity property error
Hello!
I ran the code that you provided, and my Python version was indeed old, so I upgraded it to 2.2.1 and now it compiles just fine. Many thanks, and I am looking forward to the actuator implementation

Python accel_includes_gravity property error
Hello! I have a system with 4 modules in a family and I want to set the accel_includes_gravity false, but it gives me a bunch of errors. My code: families = ['mecanumBase'] names = ['frontLeft', 'backLeft', 'frontRight', 'backRight'] group = lookup.get_group_from_names(families, names) group_command...

Re: Accelerometer question
Thank you for the reply!
A bit offtopic question, can I get the orientation feedback data with the Python API? I didn't see it mentioned in the docs, as I saw it in the C++ docs

Accelerometer question
Hello! I am trying to measure velocity as little as 0.23 m/s with the IMU, but it seems to me that the X8-9 is not very consistent in measuring accelerations this little. Is it worth trying to make it right, or it's useless to expect valid data from it? Currently I am getting the accelerometer feedb...

Re: Covariance matrix IMU
Thank you very much! It did help. However I already have wheel odometry and it's working fine, and I want to fuse my LIDAR,wheel odom and IMU data to a combined odometry with the robot_localization package
Many thanks:

Covariance matrix IMU
Hello! I am trying to calculate the odometry from the IMU data with the robot localization package, but I am stuck with the covariance/variance matrix in the IMU msg. Is this some data declared in the HEBI datasheet, relative to the sensors or should I determine the matrix somehow? If it's declared ...

Re: Custom AGV velocity question
Hello! It's me again with a question :) I tried to get started with the position control+velocity control strategy, and I started to experiment with the actuators. So I write this code: while True: group_command.position = [10.0,10.0,10.0,10.0] group_command.velocity = [3.0,2.0,3.0,2.0] group.send_c...
