Not found in the official documentation

There are a few things that are not found in the official documentation. They are discussed below.

PC Permissions

PC permissions are discussed by Bitcraze and in Flying Multiple UAVs Using ROS, however, this package does not discuss it and does not automate it.

To add PC permissions, you can run the pc_permissions.sh script. You only need to run this once (if successful). You should log out/restart once this script executes.

Using Ubuntu Linux 18.04LTS with ROS Melodic

While the package is developed for Ubuntu Linux 16.04 and ROS Kinetic, a major portion of the package is compatible with Ubuntu Linux 18.04 and ROS Melodic. The observed problems and their solutions are as follows:

• Problem with the Qualisys2Ros package:

  When build.sh is run and the Qualisys2Ros package is cloned, you will probably get an error in RTProtocol.cpp. One solution is to open crazyswarm/ros_ws/src/externalDependencies/libmotioncapture/externalDependencies/Qualisys2Ros/include/RTProtocol.cpp and replace line 451 with:

  if ((bool)ReceiveRTPacket(eType, false) == false)
  

  You can now run build.sh again and you should not get any errors.

• Problem with flashing the firmware:

  The arm compiler used for these packages is unstable/unsupported in Ubuntu 18.04. To flash the firmware please refer to virtual_machine_files/README.md.
