In this chapter, we have installed ROS Hydro on different devices (PC, VirtualBox, and BeagleBone Black) in Ubuntu. With these steps, you have everything necessary installed on your system to start working with ROS and you can also practice the examples in this book. You also have the option of installing ROS using the source code. This option is for advanced users and we recommend you use only the repository as installation as it is more common and normally does not give errors or problems.
It is a good idea to play around with ROS and its installation on a virtual machine. That way, if you have problems with the installation or with something else, you can reinstall a new copy of your operating system and start again.
Normally, with virtual machines, you will not have access to real hardware, for example, sensors or actuators. Anyway, you can use it for testing the algorithms.
