Autonomous Robots Go Swarming is an open source multi-robot simulator that was designed to study tools and control strategies for heterogeneous swarms of robots. It initially was released for Linux and Mac OS X, and in 2016 was updated to Windows systems. The core of its architecture is the simulated 3D space. Sensors and actuators can be implemented in a generic and efficient way, taking into account specific components instead of the complete robot. New robots can be inserted, reusing the already existing components and all the sensors/actuators, depending on those components working without modification. ARGoS supports multiple engines of different types and can run in parallel during an experiment. The 3D dynamics engine is based on the Open Dynamics Engine, and the 2D dynamics engine depends on the open-source physics engine library Chipmunk. It has either a 3D or 2D custom engine. The 3D visualization has a graphical user interface based on Qt4 and OpenGL. ARGoS and the control interface are written in C++.

By offering a controlled environment to practice, simulations allow educators and students to experiment, receive feedback, and improve their skills without the immediate consequences of working with real-robots.
