This article presents a design of a four-wheeled omnidirectional mobile robot for RoboCup middle size league. The mobile robot was built for the 5dpo-2000 robotic soccer team from the Department of Electrical and Computer Engineering at the University of Porto, Portugal. The robot's architecture and communication structure are presented. A nonlinear modeling and a motion analysis based on the dynamics,...
This paper mainly covers the development of a FPGA-based fuzzy controller and image processing system for a small-sized humanoid robot. All the computations are operated on an FPGA board including the real-time image processing and the fuzzy logic controller design for PK event in FIRA RoboWorld cup. At first, the specification of the hardware is introduced. The image processing is then employed for...
The problem of an effective behavior learning of autonomous robots is one of the most important tasks of the modern robotics. In fact, it is well known that the learning to optimize actions of autonomous agents in a dynamic environment is one of the most complex challenges of the intelligent system design. In this paper, we propose a hybrid approach integrating fuzzy logic system with genetic algorithm...
This paper introduces Petri net based models of robotic tasks, which can be used to analyse and synthesise task plans, taking into account a Petri net model that abstracts the relevant features from the robot environment as well. Logical analysis concerning deadlocks and resource conservation can be performed over the ordinary version of the model. A task plan modeled by a Petri net can be extracted...
In this paper, RCP (rapid control prototyping) method for robot soccer system with SIMTool, is proposed. It is composed of I/O (input/ouput) blocks and robot soccer control toolbox. I/O blocks include a input block to receive information from vision system and a output block to send control inputs to soccer robots in robot soccer system. Robot soccer control toolbox can be effectively used to implement...
