Summer Term 2014

Autonomous Robot Navigation Seminar

Tutor: 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:

  1. Information is obtained with the sensors on board the robot.
  2. Given the current information the best decision is made.
  3. 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.

The objectives of this seminar are to learn about different robotic issues and learn how to present this scientific knowledge. In particular, the following issues will be covered by this seminar:

  • Obstacle avoidance.
  • Path planning.
  • Indoor localization.
  • Outdoor localization.
  • Map building.
  • Collision avoidance for UAVs.
  • Visual-based navigation.
  • Formation control for UAVs.

This seminar is suitable for bachelor and master students and it will be taught in English. It cannot be chosen by master AI-SE students. The students need to select one of topics proposed and perform an in-depth research study. By the end of the semester, the students are required to write a scientific report and prepare an oral presentation to demonstrate the result of the study. If you want to participate in this seminar or for further information, please contact Eduardo Ferrera (

The kickoff meeting for this seminar will take place in Room S-A 126, from 14:00h to 16:00h, on Thursday, April 10th, 2014. It is mandatory to attend this meeting in order to participate in the seminar.

Case Study: Location-based Services

Lecturer: Dr. Marcus Handte
This case study covers fundamental concepts related to the development of location-based services from a theoretical and practical perspective. During the first half of the semester, basic models, algorithms, data structures and applications are introduced in a series of lectures with associated programming exercises. During the second half of the semester, participants will be designing and prototyping a location-based service for mobile (Android) devices.

The theoretical part of the case study covers the following contents:

  • Geometric, symbolic and hybrid location models
  • Localization systems and algorithms for outdoor and indoor environments
  • (Energy-)efficient location acquisition and communication
  • Server-based and server-less location data management
  • Security and privacy aspects related to location information
  • Example location-based services and applications

The case study (4SWS) is suitable for participants at the Master level. Grading is based on the practical programming work during the semester and an oral exam at the end of the semester.  Depending on the participants, the course can be held either in English or in German. The lecture part of the course will take place Thursdays from 9.00h to 11.00h in SA-126. The kickoff takes place on April 10th in SA-126. Participation during the kickoff meeting is mandatory.

Sensor Networks

Lecturer: Prof. Dr. Pedro José Marrón, Exercises: Robert Sauter
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 and Time:

  • Place:  S-A 126 (Lecture), SE 108 (Exercises)
  • Lecture: weekly Wednesday 13:00-15:15 s.t.
  • Exercises: biweekly Tuesday 10:15-11:45 s.t.

The first lecture is held on April 9th 2014; the first exercises on April 15th.

Entry in LSF: Lecture und Exercise

More information can be found on our Moodle2 page. The password will be announced in the first lecture and in the exercises.

Wireless Sensor Network Application Development Project

Tutor: Dr. Matteo Ceriotti, 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. Matteo Ceriotti at

The kickoff meeting for this project will take place in Room SA126 on Tuesday, 15.4.2014 between 13.00h and 14.30h. Participation in this meeting is mandatory.

Wireless Sensor Network Seminar

Tutor: Dr. Matteo Ceriotti, Dr. Chia-Yen Shih
This seminar aims to familiarize student with important research topics in Wireless Sensor Networks. The covered topics include: routing, localization, sensing coverage and communication connectivity, multi-channel communication, sensor networks simulation, modeling techniques on radio models, mobility models and sensing modalities, camera sensor networks.

This seminar is offered as a bachelor and a master seminar. It cannot be chosen by master AI-SE students. The student needs to select one of above topics and to perform in-depth research study on the chosen topic. By the end of the semester, the student is required to turn in a well-written report and to prepare an oral presentation to demonstrate the result of the study.

For further information about the seminar, please contact Dr. Matteo Ceriotti at

The first meeting for the seminar will take place in Room SA126 at 14:30-16:00 on Tuesday, 15.04.2014. It is mandatory to attend the first meeting in order to participate the seminar.
