PhD Anniversary – Networked and Embedded Systems

Today Omair Sarwar successfully defended his PhD dissertation entitled “Facial Privacy Protection in Airborne Recreational Videography”. Omair participated in our Erasmus Mundus Doctoral School on Interactive and Cognitive Environements and was co-supervised by Andrea Cavallaro from Queen Mary University of London. The defense committee was composed by Prof. Hermann Hellwagner […]

Unmanned aerial vehicle communications: Opportunities and challenges

Wireless communications is essential for many applications with commercial drones. Omid Semiari interviewed Christian Bettstetter about this exciting topic at the interface of communications and robotics for the latest IEEE ComSoc TCCN newsletter. To start, could you please explain why “communications” matter for unmanned aerial vehicles (UAVs) and what are […]

“I worked hard for this”

Jennifer Simonjan’s work focuses on camera networks. In conversation with ad astra she tells us why she does not fear ubiquitous camera surveillance, what she recently learned in Atlanta about nano cameras, and what it took for her, a first-generation student from an environment that was hardly technologically-minded, to gain […]

“Drones are here to stay. Get used to it.”

This statement was the title of a TIME article, which was included in the magazine’s special report on “The Drone Age”. We asked Christian Bettstetter to tell us what today’s drones can do and what drone(swarms) are not yet capable of. One thing is certain: Our airspace is going to […]

UAV motion planning for multi-coverage

Unmanned aerial vehicles (UAVs) with onboard cameras are increasingly deployed in various applications including surveying, search and rescue, inspection as well as video production. In all these applications, the UAVs move – in many cases autonomously – to capture imagery of sufficient quality of the environment or objects of interest.  […]

Aerospace best paper award

Stochastic Trajectory Generation Using Particle Swarm Optimization for Quadrotor Unmanned Aerial Vehicles (UAVs) has been selected as the best research article published in 2017 in the MDPI Aerospace journal. The paper is co-authored by Babak Salamat and Andrea Tonello. It provides a realistic stochastic trajectory generation method for unmanned aerial vehicles. […]

UWB connectivity in industrial environments

The introduction of wireless connectivity in industrial environments promises a rapid and cost-effective reconfiguration of machines and sensors. A key question in this context is: Which wireless technology is best suited for industrial settings? Many of the prevalent technologies, like WiFi and ZigBee, do not meet the requirements of certain […]

Exploring nano-cameras during research visit at Georgia Tech

Jennifer Simonjan, research and teaching staff member at the Pervasive Computing Group, spent three months, from January to March 2018, as visiting researcher in the Broadband Wireless Networking Lab of Professor Ian F. Akyildiz at the Georgia Institute of Technology. There she conducted research in the field of nanoscale optics […]

The Spiderino Swarm Robot

Playing with toys pays off! We have designed a low-cost research robot based on the Hexbug Spider toy in order to combine the interesting locomotion of the toy with some embedded intelligence. Our modification replaces the robot head with a 3D-printed adapter, consisting of two parts to provide space for […]

One time for all: Synchronising time in drone swarms

Wherever several clocks tick simultaneously, it is tricky to get them all to display precisely the same time. This can be a challenge for drone swarms that are airborne together. To tackle this problem, young scientist Agata Gniewek is developing new technologies. The difficulty is in the detail: When drone […]
