Summer Term 2015

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. Once every two weeks the students need to select one of the proposed topics and perform a short research in the field, write a report and prepare an oral presentation to demonstrate the acquired knowledge. 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 9th, 2015. 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 on top of an existing infrastructure for indoor localization.

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 Thursday, April 9th in SA-126. Participation during the kickoff meeting is mandatory. To access the materials (slides, papers, etc.) of the course and to get important notifications, please subscribe to the Moodle page of the course. The password is LBS15.

Context Recognition 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 bachelor and master/diploma level. However, 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

The kickoff meeting for this seminar will take place on Thursday, 16.04.2015 between 16.00h and 17.30h in SA 126. Participation in this meeting is mandatory.

Sensor Networks

Lecturer: Prof. Dr. Pedro José Marrón, Exercises: Songwei Fu
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 018 (Lecture), S-A 018 (Exercises)
  • Lecture: weekly Wednesday 12:00-14:15 s.t.
  • Exercises: biweekly Wednesday  14:15- 16:00 s.t.

The first lecture is held on April 15th 2015; 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
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 radios. 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 networks
  • Interfacing between the user and the deployed WSN

This course will be taught in English. If you are not sure whether you fulfill the requirements or if you want to participate in the project, please send an email to

The kickoff meeting for this project will take place on Tuesday, 07.04.2015 between 11.00h and 12.30h in Room S-A 126. Participation in this meeting is mandatory.
