Winter Term 2013/14


Aktivitätserkennung mit mobilen Geräten (Bachelor-Projekt)

Tutor: Marcus Handte 
More and more mobile devices are equipped with a broad variety of sensors such as gyroscopes, accelerometers, video cameras, and microphones. To provide better task support, future applications will have to use these sensors to determine the state of their environment unobtrusively. As a simple example consider smart phones that are deactivating the touch screen when they detect that the user is holding them close to his ear.

In more complicated scenarios, this requires applications to “make sense” of the multitude of inputs received at any point in time. To simplify this task, the participants will develop a software system that is able to automatically categorize different situations. This system will be developed for and tested on Android-based mobile phones which will be given out to the participants. Due to the use of Android as operating system, participants should be able to program in Java.

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

The kickoff meeting for this project will take place on Thursday, 17.10.2013 between 9.00h and 10.30h  in S-A 126. Participation in this meeting is mandatory.

Autonomous Navigation for Middle-size Robots Project

Tutor: Prof. Dr. Pedro José Marrón
Contact: Eduardo Ferrera

Nowadays, mobile robots are used in many applications, such as rescue missions, surveillance or people assistance. In these applications, robots usually need to operate in unknown environments, so they need to obtain information with their sensors and take intelligent decisions. In general, they proceed in a loop with several steps: (i) Information is obtained with the sensors on board the robot; (ii)

Given the current information the best decision is made; (iii) The decision is carried out by the robot autonomously.

Mainly, mobile robots need to know where they are located and how to navigate safely to other places. For that, they have to use external sensors (e.g., GPS, compass, laser, etc.), plan trajectories, avoid obstacles, etc.

In this project, the motivating application will be a rescue mission in an indoor building after a catastrophe. For that, a robotic simulator will be used in order to develop algorithms to localize a robot, to navigate avoiding obstacles, to build a map of the environment and find the victims and to report back the results. The Robotic Operating System (ROS) will be used in order to program
the robot and communicate to the simulator.

This course will be taught in English and will require programming in C++. The project is suitable for students at the bachelor and the master level. However, the course contents and the requirements for passing are different depending on the level. As a consequence, it is not possible to create mixed teams. If you want to participate in this project or further information, please contact Eduardo Ferrera.

The kickoff meeting for this project will take place in Room S-A 126, from 16:00h to 18:00h, on Thursday, October 17th, 2013. It is mandatory to attend this meeting in order to participate in the project.

Kontexterkennung Seminar

Tutor: Marcus Handte 

Nowadays, most devices are equipped with differnt types of networking technology and a broad spectrum of sensors. Examples include gyroscopes, accelerometers, cameras, and microphones. To provide better task support, future applications will have to use the sensors of multiple devices to determine the state of their environment in an automated fashion. This requires novel software systems and signal processing algorithms to derive high-level context information from low-level sensor readings.

The seminar topics will cover a selection of systems and algorithms to recognize different types of context. Furthermore, they cover supportive architectures and protocols to recognize context in a distributed manner. Thereby, the seminar focuses on light-weight approaches that can be implemented on resource-poor devices. Participants will be able to select their topic of choice from the set of available topics.

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 master/diploma level. It cannot be chosen by master AI-SE students. Furthermore, depending on the number and type of participants, this seminar might be given in English and German. Please also note that the maximum number of participants is limited. If you want to participate in the seminar, please send an email to marcus.handte@uni-due.de.

The kickoff meeting for this seminar will take place on Thursday, 17.10.2013 between 10.30h and 12.00h in S-A 126. Participation in this meeting is mandatory.

Wireless Sensor Network Application Development Project

Tutor: Dr. Chia-Yen Shih
Wireless Sensor Networks (WSNs) have been widely deployed in many application domains including environmental monitoring, surveillance, healthcare, automation control and more. A typical WSN consists of a set of low-powered and inexpensive embedded sensor devices with specific sensing modalities and with computation as well as communication capabilities. These devices collaborate with each other by exchanging data through energy-efficient, short-range radio. The application provides its services by manipulating the sensory data collected by the deployed WSN.

In this project, you will learn how to develop an integrated application providing services by making use of a WSN. The topics that will be covered include:

  • Wireless sensor system programming
  • Sensory data collection
  • Data delivery and communication through IEEE 802.15.4/ZigBee networks
  • Interfacing between the user and the deployed WSN

For further information about the project, please contact Dr. Chia-Yen Shih at chia-yen.shih@uni-due.de.

The kickoff meeting for this project will take place in Room S-A 126 at 13.30h (to 15.00h) on Tuesday, 22.10.2013. Participation in this meeting is mandatory.
