چکیده

Communication among a group of robots should in principle improve the overall performance of the team of robots, as robots may share their world views and may negotiate task assignments. However, in practice, effectively handling in real-time multi-robot merge of information and coordination is a challenging task. In this paper, we present the approach that we have successfully developed for a team of communicating soccer robots acting in a highly dynamic environment. Our approach involves creating shared potential functions based on shared positions of relevant obstacles in the world. The biases introduced in the potential functions are general and they could in principle be provided by external sources, such as a human or robot coach. We provide controlled experiments to analyze the impact of our approach in the overall performance of a robot team.

Effects of Moving Landmark’s Speed on Multi-Robot Simultaneous Localization and Mapping in Dynamic Environments

Even when simultaneous localization and mapping (SLAM) solutions have been broadly developed, the vast majority of them relate to a single robot performing measurements in static environments. Researches show that the performance of SLAM algorithms deteriorates under dynamic environments. In this paper, a multi-robot simultaneous localization and mapping (MR-SLAM) system is implemented within a...

Motivation and Context-Based Multi-Robot Architecture for Dynamic Task, Role and Behavior Selections

This paper proposes a multi-robot coordination architecture for dynamic task, role and behavior selections. The proposed architecture employs the motivation of task, the utility of role, a probabilistic behavior selection and a team strategy for efficient multi-robot coordination. Multiple robots in a team can coordinate with each other by selecting appropriate task, role and behavior in advers...

Multi-robot Control in Highly Dynamic, Competitive Environments

The control and coordination of multiple mobile robots is a challenging task; particularly in environments with multiple, rapidly moving obstacles and agents. This paper describes a robust approach to multi-robot control, where robustness is gained from competency at every layer of robot control. The layers are: (i) a central coordination system (MAPS), (ii) an action system (AES), (iii) a navi...

Multi-Robot Dynamic Role Assignment and Coordination Through Shared Potential Fields

Role assignment and coordination are difficult issues for multi-robot systems, especially in highly dynamic tasks. Robot soccer is one such task and it provides a unique challenge for multi-robot research. In this paper, we contribute the approach that we successfully developed for CMPACK’02 , our team for the RoboCup-2002 Sony legged league. The RoboCup-2002 Sony robots were equipped with wire...

Dynamic Robot Networks: a Coordination Platform for Multi-robot Systems

A large number of tasks, from manufacturing to planetary exploration, have been successfully accomplished using single robot systems. Many of these tasks could be completed faster, more reliably, and on a larger scale using a cooperating team of autonomous mobile robots. However, robots must be able to coordinate their actions before cooperation is possible. This work aims to enable robots with...

Distributed versus centralistic action planning for multi-agent-teams in complex, dynamic domains

While distributed problem solving has many advantages the efficient coordination of multiple autonomous robots is still not always possible. There are several different ways of how to approach the coordination problem. Most of those require excessive communication in order to negotiate a valid global plan. Yet the global plan after the coordination might still be less effective than a plan gene...
