Hi!

I am using Roll, pitch and yaw from a Autopilot module (ardu pilot mega 2.6 having IMU in it) and fovisros visual odometry package as a input to robotpose_ekf to get stable odometry. But i am getting this error.

[ERROR] [1416515090.746733573]: filter time older than vo message buffer

Can anyone help me with this error.

Thank You! Bhargav

EDIT : After refering to this link[http://wiki.ros.org/robot_pose_ekf/Troubleshooting], I understood that fovis_ros is publishing message at lower rate. Is it so?
