This paper describes robotstadium: an online simulation contest based on the new RoboCup Nao Standard League. The simulation features two teams with four Nao robots each team, a ball and a soccer field corresponding the specifications of the real setup used for the new RoboCup Standard League using the Nao robot. Participation to the contest is free of charge and open to anyone. Competitors can...

Formerly I presented a metric navigation method in the Webots mobile robot simulator. The navigating Khepera-like robot builds an occupancy grid of the environment and explores the square-shaped room around with a value iteration algorithm. Now I created a topological navigation procedure based on the occupancy grid process. The extension by a skeletonization algorithm results a graph of import...

This project aims at implementing a close-to-reality model of the recently developed Cheetah robot [1] in Webots [2], a commercial mobile robot simulation software developed by Cyberbotics Ltd. Furthermore, a pre-developed CPG [3] will be applied to the robot to determine feasible gaits and their optimal parameters for the Cheetah robot. Special interest lies in the characterization of the usef...

in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...

This article presents a multiagent simulation environment for studying agents' sociopolitical attitudes. It departs from a previously proposed concept of agents with sociopolitical attitudes, a high-level theoretical and conceptual model proposed by Petric et al. (2002) that was intended for conversational agents. In contrast, our work pursues a bottom-up simulation philosophy where attitudes a...

This project is a part of a bigger project aiming to develop bio-inspired climbing robots for space exploration. My goal is to provide a tool to simulate the physics of those robots, design them and test their controllers. Therefore my project is divided into three main steps. The first step consists in developing a physical plugin for Webots in order to be able to simulate the bio-inspired adh...

In this paper, stable modifiable walking pattern algorithm is proposed using evolutionary optimized central pattern generator (CPG). Sensory feedback pathways in CPG are proposed, which use force sensing resistor (FSR) signals. For the optimization of CPG parameters, two-phase evolutionary programming (TPEP) is employed. Modifiable walking pattern generator (MWPG) generates position trajectory ...

The advantages and disadvantages of evolving neural control systems for mobile robots using genetic algorithms are investigated. The Khepera robot is trained using the evolutionary neural networks (E“) algorithm for the task of obstacle avoidance. The feasibility of using Q-learning for robot learning is also studied. It is found that Q-learning can be successfully used to train a robot and is ...

In this article, we provide an overview of three humanoid soccer platforms currently in use at RoboCup: 3D simulation, the humanoid Standard Platform League (SPL), and the Webots-based simulator released with the SPL. Although these platforms trace different historical roots, today they share the same robot model, the Aldebaran Nao. Consequently, they face a similar set of challenges, primary a...
