RoboCup Small Size League Simulator

System Requirements

grSim will likely run on a modern dual core PC with good graphics card. Typical configuration is:

  • Dual Core CPU (2.0 Ghz+)
  • 1GB of RAM
  • 256MB nVidia or ATI graphics card

Note that it may run on lower end equipment though good performance is not guaranteed.

Software Requirements

grSim uses these libraries:

  • Qt 4.8+ (provided by libqt4-dev on debian based distros)
  • OpenGL
  • Open Dynamics Engine (ODE)
  • VarTypes Library
  • Google ProtoBuf


Please refer to INSTALL file.


Receiving data from grSim is exactly like receiving from SSL-Vision using Google Protobuf library Sending data to Simulator is also possible using Google Protobuf. Sample clients are included in clients folder. There are two clients available, qt-based and Java-based. The native client is compiled during the grSim compilation. To compile the Java client, please consult client's README file.


Please refer to the CHANGELOG file.
