Hi, I am using ubuntu14.04 and ros indigo now. I followed the instruction from https://github.com/ethz-asl/nbvplanner/wiki/Installation-Instructions to configured the environment successfully. when i run following command roslaunch interface_nbvp_rotors flat_exploration.launch I get the following errors and the UAV are just drifting in gazebo. [ERROR] [1542903232.547584120, 0.350000000]: "navigation" passed to lookupTransform argument target_frame does not exist. [ERROR] [1542903232.605931369, 0.410000000]: Lookup would require extrapolation at time 0.410000000, but only time 0.510000000 is in the buffer, when looking up transform from frame [world] to frame [navigation] [ERROR] [1542903249.365794165, 17.050000000]: "world" passed to lookupTransform argument target_frame does not exist. Is there any methods I can solve this?

I have done nothing, but it works now. I do not know the reason.
