A unified mathematical model for synchronisation and swarming has been proposed recently. Each system entity, called “swarmalator”, coordinates its internal phase and location with the other entities in a way that these two attributes are mutually coupled. This paper realises and studies, for the first time, the concept of swarmalators in technical systems. We adapt and extend the original model for its use on mobile robots and implement it in the Robot Operating System 2 (ROS 2). Simulations and experiments with small robots demonstrate the feasibility of the model and show its potential to be applied in real-world systems. All types of space-time patterns achieved in theory can be reproduced in practice. Applications can be found in monitoring, exploration, entertainment and art, among other domains.
A multidisciplinary team at the University of Klagenfurt is due to deliver initial insights on the efficient operation of a drone-based delivery network. Doctoral student Pasquale Grippa will present the results at the Robotics: Science and Systems event taking place at MIT this week.
An interdisciplinary workshop on self-organization and swarm intelligence in cyber physical systems was held at Lakeside Labs this week. Experts presented their work and discussed open issues in this exciting field.
Samira Hayat and I attended re:publica 2017 in Berlin. It was an exciting event not least because Samira gave a very personal talk about drones and their application in disaster response.
I visited the Center for Aerial Robotics Research and Education in Toronto. It has an exciting research portfolio in small drone systems. My invited talk discussed wireless communications for drones and novel results for job selection.
We highlight research issues for wireless networking in aerial systems consisting of multiple small autonomous drones. Among these challenges are video streaming, synchronization, security and safety, and interference management.
Mobile robots in explorer missions need to charge their batteries from time to time. Different policies for coordinated recharging in teams of robots are evaluated.
“One of my first memories relating to the word ‘drones’ is that of an online video of a man. He was angry and revengeful [and] told the story of how he lost his whole family,” Samira Hayat began her talk at the 2016 TEDx event Ripples of Curiosity at the European research center CERN near Geneva on November 5.
New packages for the Robot Operating System (ROS) are available for autonomous exploration of unknown environments using collaborating mobile robots equipped with cameras. The software offers wireless ad hoc communications between robots, merging of maps from different robots, and coordinated selection of exploration frontiers. A prototype with four robots was built that demonstrates its functionality in an indoor environment.
The Institute of Networked and Embedded Systems and Lakeside Labs opened their laboratories to the public on March 11. About 120 visitors informed themselves and discussed about ongoing research in the domains of mobile systems, pervasive computing, self-organizing systems, multimedia systems, and smart energy grids.
