According to a Freshmeat.net announcement, a new, physics-based 2D robot simulator has been released by the EPFL Laboratory of Intelligent Systems. The simulator, named Enki, currently supports Khepera, S-Bot, and Alice robots. The code, which is currently in Beta release, is written in C++ and includes kinematics, collisions, sensors, and cameras. There is also limited support for friction. How fast is it? Fast enough to simulate multiple robots simulatneously hundreds of times faster than real time on a typical desktop computer. Enki can be integrated with EPFL's Open Evolutionary Framework, TEEM, to act as a simulator for testing swarm algorithms. A discussion forum has been set up for Enki users. Enki was developed by Stephane Magnenat, Markus Waibel, Vincent Porchet, Antoine Beyeler, and Michele Bongiovanni. It is Free Software licensed under the GNU GPL.
