 systems . Its components include the Player network server and Stage and Gazebo robot platform simulators. Although accurate statistics are hard to obtain, Player is one of the most popular open-source robot interfaces in research and post-secondary education. Most of the major intelligent robotics journals and conferences regularly publish papers featuring real and simulated robot experiments using Player, Stage and Gazebo.

Overview

The Player Project is an umbrella under which three robotics-related software projects are currently developed. These include the Player networked robotics server, the Stage 2D robot simulation environment, and the Gazebo 3D robot simulation environment. The project was founded in 2000 by Brian Gerkey, Richard Vaughan

. Player can be described as a 'robot abstraction layer,' in that all devices are abstracted into a set of pre-defined interfaces.

Player supports a wide variety of hardware (sensor devices and robot platforms alike). It also contains client library support for a number of programming languages including C, C++
C++
C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell...

. Stage provides a basic simulation environment that can be scaled to model one to hundreds of robots at a time. Stage can be used alone to simulate robot behaviors via user-defined control programs. Stage can also interface with Player, allowing users of the Player to access simulated sensors and devices through the Player interfaces.
