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.
Wireless networks are often modeled using tools from stochastic geometry. A team of researchers from Klagenfurt, Athens, and Notre Dame now contributed to these tools by solving general sum-product functionals for Poisson point processes. Link outage probabilities are derived for networks with interference and Nakagami fading.
Aerial delivery services using small unmanned aerial vehicles (UAVs) have been proposed by major online retailers, logistics companies, and startups. An interdisciplinary project team at the University of Klagenfurt aims at contributing to the architectural setup and decentralized control of such future systems.
Professors are often asked by master and PhD students whether an academic career can be recommended. Christian Bettstetter and Bernhard Rinner summarize their personal views on the characteristics and career paths of academic jobs and give advice to people who choose an academic career.
A new article published in the IEEE Communications Magazine discusses some aspects of wireless communications for different applications involving small drones.
Written by Christian Bettstetter. Photos by Christian Philipp for Lakeside Labs. The Institute of Networked and Embedded Systems and Lakeside Labs opened their doors to the public. About 120 visitors informed themselves about research in mobile systems, pervasive computing, self-organizing systems, multimedia systems, and smart grids.
The precision of synchronization algorithms based on the theory of pulse-coupled oscillators is evaluated on FPGA-based radios for the first time. Measurements show that such algorithms can reach precision in the low microsecond range when being implemented in the physical layer.
