Thinking question: 1. PSE Advent Calendar 2022 (Day 11): The other side of Christmas, If you see the "cross", you're on the right track. In this code, what we basically do is subscribe to the /imu_data topic and extract only the yaw and pitch values. You have to integrate the acceleration yourself, but this will most likely give horrible results. lang. NOTE: The older release (mv0.8) instructions are here. The accel errors will grow without bounds and your pose will be junk. from launch import launchdescription from launch_ros.actions import node def generate_launch_description (): return . 76 // transform from the /gyro to the /accel frame to the gyroscope data Publishers: list of all nodes publishing on the topic. your IMU doesn\'t produce an orientation \n# estimate), please set element 0 of the associated covariance matrix to -1\n# If you are interpreting this message, please check for a value of -1 in the first element of each \n# covariance matrix, and disregard the associated estimate.\n\nHeader header\n\ngeometry_msgs/Quaternion orientation\nfloat64[9] orientation_covariance # Row major about x, y, z axes\n\ngeometry_msgs/Vector3 angular_velocity\nfloat64[9] angular_velocity_covariance # Row major about x, y, z axes\n\ngeometry_msgs/Vector3 linear_acceleration\nfloat64[9] linear_acceleration_covariance # Row major x, y z \n". That is usually done with gyros and a 3D accel or perhaps a camera (could give you a rough estimate). In short, a ROS publisher is a ROS node that publishes a specific type of ROS message over a given ROS topic. imu_data.header.stamp, ros::Time::now(); You can also find the sensor_msgs messages type in the ROS system, and part of it can hold the IMU's numeric values of sensors readings. Run rviz, set the fixed frame to imu and add a visualization of type rviz_imu_plugin (part of the imu_tools package). So, now that I have this, what do I do with the unfillable values inside a sensor_msgs/Imu message? I am getting the values by translating it to g's, then multiplying that by 9.80665 to get the m/s^2 readings.
