The aim of my research is the analysis and synthesis of autonomous systems. My main interest is focused on the simulation of adaptive behavior in mobile robots and insect-like multi agent systems. I also investigate artificial intelligence (neural networks, evolutionary algorithms, reinforcement learning) as a method for mobile robot controlling.
The primary experimentation environment I use is the Webots mobile
robot simulator from Cyberbotics Ltd., Switzerland.
After I was the runner up of the 1st Artificial Life
Creators Contest organized by Cyberbotics Ltd. in 1999,
I won the second contest in 2000 and obtained the simulator license
as the first prize.
For multi agent experiments I use Repast.
The current research deals with the creation and the usage of cognitive map and the navigation of robots and ants. In case of robots I compare the usefulness of metric and topological map building approaches using probabilistic environment desriptions, especially occupancy grid. In case of ants I focus on the information content of the environment and its transfer among food foraging ants.
I was the co-organizor of the Budapest University and Technology 2nd 24 hour programming contest in 2002.
I also created a French-Hungarian electronic dictionary which is in use at SZTAKI.
