Introduction

Developing software for robots is not as easy as developing any other type of software. To build robots, you need methods and functions that enable you to access sensor information, control robot parts, and connect with the robot. These methods and functions are present in ROS, making it easier to build a virtual robot.

ROS is a framework that is compatible with Ubuntu (Linux) for writing robot software. It is a set of libraries and tools through which it is possible to build and create various robotic behaviors. One of the most interesting features about this framework is that the developed code can be adapted for any other robot. ROS also gives you a chance to work on several machines simultaneously; for instance, if you want to use a robot to collect apples, you can use a computer to obtain the camera information of the apple and process it, another machine to launch the movement that commands the robot, and finally the robot will pick up the apple. By following this workflow...
