This warehouse is used to integrate nine-axis IMU and wheel ohmmeter data in ros2 humble, the parameters of which I adjusted by myself after many experiments.
You'll first need a wheeled odometer (odom1) and a nine-axis IMU from either Magic Technologies or Alpriz Energy. The driver code is wrong in Humble, but I've corrected it in my other warehouses, and it's called imu/data_raw.
