robot_pose_ekf hardcoded topics and tf
Why are "odom", "imu_data" and "base_footprint" hardcoded in robot_pose_ekf? Why not pass these as parameters similar to "odom_combined"? see below:
nh_private.param("input_odom", input_odom_, std::string("odom"));
nh_private.param("input_imu", input_imu_, std::string("imu_data"));
nh_private.param("robot_frame", robot_frame_, std::string("base_footprint"));
The above parameters are not currently defined in robot_pose_ekf.
