Player Project is an unison of 3 softwares, Player - the server for controlling robots, Stage - 2.5D simulations & Gazebo - 3D simulations. Later both Stage and Gazebo were developed as standalone and also incorporated into Robot Operating System (ROS). Further details may be found at, http://playerstage.sourceforge.net/.

Mobotica started off in March 2010 with an article on installation of Player/Stage on Ubuntu 9.04 and that has been the most popular article of the blogspot.
For all Player/Stage related articles; http://mobotica.blogspot.in/search/label/Player%2FStage
NOTE : All postings in this blog use Player with Stage, Gazebo is used as standalone or with ROS never with Player
