on uwsim, orientation from topic pose and topic imu is different. Why?
on uwsim, orientation from topic pose and topic imu is different. I set the initial yaw of auv as 0 by modifying yaml file. Quaternion from topic pose is x=0 y=0 z=0 w=1. Quaternion from topic imu is x=0 y=0 z=1 w=0. They are different! why??
