René Hölbling and Kevin Moser from Lakeside Park (Klagenfurt) developed a nice maze solving algorithm for the e-puck robot. It uses a combination of different sensors (infra-red light sensor and proximity sensor) to achieve maze solving. The robot follows the right wall, until it finds its goal (a dark sector in the maze), then the LEDs are blinking and it plays a sound when it has finished.

The same setup was also simulated with Webots - as you see in this video, and it worked like the real e-puck.

Jonathan Mullins completed a Bachelor of Software Engineering at Monash University, and used Aseba for the simulation component of his research in Swarm Robotics. He ported the Swis2D audio plugin for Webots into Aseba Playground to facilitate audio simulation.
