We can download the Ubuntu image which is prebuilt with ROS, OpenCV, and PCL for Odroid and the ROS built-in Raspbian image for Raspberry Pi 2 and can install to a micro SD card, preferably 16GB. Format the micro SD card in the FAT32 file system and we can either use the SD card adapter or the USB-memory card reader for connecting to a PC.

We can either install OS in Windows or in Linux. The procedure for installing OS
on these boards follows.
