Is sensor timestamp can modify robot_pose_ekf accuracy ?
Hello,
I'm using a visual odometry working on a workstation connected by wifi to the Turtlebot. I have synchronized the time in the workstation related to the turtlebot with: sudo ntpdate tutlebot_IP writed on one workstation terminal. But maybe it's still a time lag.
Therefore my question is, If the /vo is published with a timestamp lag compared with odom and imu timestamp, is it possible to impact the accuracy of the robot_pose_ekf algorithm.
