Hello, I am a student researcher doing research on drone trajectory planning and I need to run a few preliminary simulations to capture data; Keep in mind I am very new to ROS and Gazebo. I am attempting to run a launch file, but I get errors for the default models i.e. sun, and ground_plane. I am using Gazebo7 running on UBUNTU 16.04.
