• Run a fan while compiling (onboard or offboard) to avoid damaging the board.

cd ~/ws_ros

There are helper scripts for ground station computer that sets up ROS_MASTER_URI and launches necessary nodes. This assumes quadrotor_control and snavquad_interface is compiled in your laptop workspace. For example dragonfly4 platform Enter the vehicle number accordingly.

roscd snavquad_interface/scripts
./tmux_ground_station 4

There are helper scripts for recording bag file in the snavquad_interface/scripts/capture folder. On the mav tmux session, switch to the Aux tab, there should be a pane that already has the following keys. Just hit Enter to start recording the bag. If the mav has micro-SD card it will bag it to /media/sdcard, else to the home folder ~/.

roscd snavquad_interface/scripts/capture
./record/sh 4
