Summer Term 2019

Tutor: Marcus Handte, Alexander Golkowski

TurtleBot 3 is a low-cost, open source robot kit that can be used to realize a broad spectrum of different robotic applications. A TurtleBot typically integrates different actuators, e.g. motors that drive the robot’s wheels, sensors, e.g. a LIDAR or an IMU, a base controller and a battery. To implement the application logic, the base controller is often connected to a PC which runs software components to perform core functions such as localization, mapping and navigation, among others.

The goal of this project is to develop a more cost-efficient solution for application development by replacing the PC platform with a mobile phone based on Android. Towards this end, students will be designing and implementing a communication mechanism between the base controller of the TurtleBot 3 platform and an Android phone that enables the mobile phone to receive the sensor data and to control the connected actuators. During the project, students will become familiar with the TurtleBot robot kit and mobile application development.

Participants in this course are expected to be highly motivated and must have a solid understanding of the Java programming language. In addition, participants should be able to work with C. Note that due to the limited availability of TurtleBot hardware, the number of participants in this project is strictly limited. If you want to participate in this course, please send an email to marcus.handte@uni-due.de to indicate your interest.

This course may be held in German and English depending on the participants. The project is suitable for students at the bachelor level. If you are not sure whether you fulfill the requirements or if you have any questions, please send an email to marcus.handte@uni-due.de.

In dieser Vorlesung werden Aspekte, Funktionen und Kommunikationsprotokolle TCP/IP-basierter Netze behandelt. Dabei werden einerseits bereits in „Kommunikationsnetze 1“ angesprochene Themen vertieft, andererseits werden aber auch dort nicht behandelte, für das heutige Internet wichtige Themenbereiche behandelt. Inhalte im Einzelnen:

• Überblick über Grundbegriffe der technischen Kommunikation, der geschichteten Protokollarchitekturen und das OSI-Referenzmodell
• IPv6
• Routing und Routing-Protokolle
• Multicast und Multicast Routing
• Mechanismen und Protokolle der Transportschicht
• Infrastruktur-Protokolle
• Sicherheit in Computernetzwerken

This lecture at the Master level covers the fundamentals of past and recent pervasive computing research with a specific focus on the following four areas:

• System-support and programming abstractions for adaptive distributed applications
• Recognition, modelling and management aspects of contextual information
• Novel user interface examples and guidelines for pervasive computing applications

Students participating in this course should have at least basic knowledge in the areas of networking and database technology. Knowledge in machine learning and human-computer-interaction could be beneficial but is not mandatory.

The practical exercises will focus system-support for adaptive distributed applications. As part of the exercises, students will be developing a communication middleware for spontaneously networked devices using an object-oriented programming language such as Java or C#.

Place and Time:

• Lecture: Wednesdays (starting in the first week of the lecture period), from 16:00h to 18:00h in SA 215
• Exercises: Thursdays (starting in the second week of the lecture period), from 16:00h to 18:00h in S 215

More Information:

The moodle page of the course is available here. The subscription password will be given out during the first lecture. The course will start with the first lecture on Wednesday, October 11th. There will be no exercise during the first week. Detailed information about the contents and organization of the course will be given out during the first lecture. If you have further questions, feel free to contact marcus.handte@uni-due.de.

Have you ever had problems connecting to the Internet with your smartphone due to a weak or non-existing WiFi signal? What if you could see those wireless signals in the environment and utilise them, e.g., to find a more beneficial spot for either your phone or conversely the wireless router to provide a better signal coverage? Now think about the Internet of Things made of billions of wireless devices, whose functionality depends on wireless connectivity. This project group targets the visualisation of wireless waves emitted by IoT devices as if they were visible light ones, with the goal of supporting users in planning functional IoT systems.

After a series of lectures discussing the behaviour of wireless signals in real environment and tutorials in which the wireless modelling engine developed in prior research work will be introduced, the participants will present specific techniques of relevance for the project. In particular, the attendees will learn about how wireless signals propagate in an environment with obstacles as well as how 3D visualisation engines can be exploited to represent such information. Depending on the number of students, we will also explore the techniques that will allow to operate such visualisation on a smartphone and navigate in the wireless environment while the user moves around.

Afterwards, the participants will design, implement and experiment with a practical system in which the acquired knowledge will be exploited to prototype a visualisation engine able to represent the wireless signals in real-world scenarios.

This project group is only suitable for AI-SE master students and it will be taught in English. The number of participants in this course ranges between 6 and 10. The admission to this course is managed centrally.

If you have questions or if you want to participate in the project, please send an email to matteo.ceriotti@uni-due.de.

Since the beginning of the century, the ubiquity of accurate location information in outdoor settings and the growing availability of mobile devices such as smartphones has led to the development of a plethora of location-based services and applications. In 2007 Raper et al. define location-based services (LBS) as systems that make use of the person’s current or previous location to deliver information or trigger some action. To make such services possible different technologies have to be combined to a complete system.

This seminar aims at familiarizing students with important research topics in this field. The covered topics include, among others, outdoor and indoor positioning systems, routing and navigation, modeling of map and building information as well as complete system architectures. Participants will have to do a literature research and they will have to create a high quality written report. Furthermore, they will have to give an oral presentation of their topics.

This seminar is suitable for students at the bachelor and master level. However, it cannot be chosen by master AI-SE students. This seminar is given in English. Please also note that the maximum number of participants is limited. If you have questions regarding this seminar, please send an email to stephan.j.wagner@uni-due.de.

This lecture describes the fundamental concepts of sensor networks and how they differ from traditional networked systems that do not take energy and resource constraints into account. During the experiments, the students will deal with real-world deployments of sensor networks and use real sensor nodes to understand better the effects of real-world phenomena in aspects like link quality, localization, etc.

• Place:  SA-215 (Lecture and Exercises)
• Lecture: weekly Wednesday 10:00 – 12:00 s.t.
• Exercises: biweekly Wednesday 12:00 – 14:00 s.t.
