Robust Localization for Multi-robot Formations: An Experimental Evaluation of an Extended GM-PHD Filter

Alcherio Martinoli, Alicja Barbara Roelofsen, Michiaki Hirayama

This paper presents a thorough experimental evaluation of an extended Gaussian Mixture Probability Hypothesis Density filter which is able to provide state estimates for the maintenance of a multirobot formation, even when the communication fails and the t ...

An Institutional Approach to Normative Distributed Robotics for Mixed Societies of Humans and Robots

Alicja Barbara Roelofsen

We are entering the era of robots, for everyone, everywhere. The expectations of the robots being reliable, intelligent and friendly artificial creatures drive the key challenges of the state-of-the-art robotics: technological, practical and social. The la ...

A robust localization system for multi-robot formations based on an extension of a Gaussian mixture probability hypothesis density filter

Alcherio Martinoli, Alicja Barbara Roelofsen

This paper presents a strategy for providing reliable state estimates that allow a group of robots to realize a formation even when communication fails and the tracking data alone is insufficient for maintaining a stable formation. Furthermore, the trackin ...

Towards Norm Realization in Institutions Mediating Human-Robot Societies

Alcherio Martinoli, Stevan Tomic, Alicja Barbara Roelofsen

Social norms are the understandings that govern the behavior of members of a society. As such, they regulate communication, cooperation and other social interactions. Robots capable of reasoning about social norms are more likely to be recognized as an ext ...

A Robust Relative Positioning System for Multi-Robot Formations Leveraging an Extended GM-PHD Filter

Alcherio Martinoli, Alicja Barbara Roelofsen

We propose a multi-robot tracking method to provide state estimates that allow a group of robots to maintain a formation even when the communication fails. We extend a Gaussian Mixture Probability Hypothesis Density filter to incorporate, firstly, absolute ...

Graph-Based Distributed Control for Adaptive Multi-Robot Patrolling through Local Formation Transformation

Alcherio Martinoli, José Nuno Ferreira Maia Pereira, Alicja Barbara Roelofsen, Rodrigo Martins de Matos Ventura

Multi-robot cooperative navigation in real-world environments is essential in many applications, including surveillance and search-and-rescue missions. State-of-the-art methods for cooperative navigation are often tested in ideal laboratory conditions and ...

Lidar-Based Relative Position Estimation and Tracking for Multi-Robot Systems

Alcherio Martinoli, José Nuno Ferreira Maia Pereira, Alicja Barbara Roelofsen, Rodrigo Martins de Matos Ventura

Relative positioning systems play a vital role in current multi-robot systems. We present a self-contained detection and tracking approach, where a robot estimates a distance (range) and an angle (bearing) to another robot using measurements extracted from ...
