Robot Pose EKF: Covariance specified for measurement on topic imu is zero
I publish the orientation covariance of the IMU message with the given -1 in the first field as stated in the description of the message: http://docs.ros.org/api/sensor_msgs/html/msg/Imu.html
However, when I run the code, i come up with the following error:
Covariance specified for measurement on topic imu is zero
How do I specify my covariance in order to let the robot pose ekf ignore the orientation part?
Why don't you just set orientation values to false in your config file for ekf?
