Informationen und Networking für Outgoings des FB04

Begrüßung aller neuen Studierenden des Fachbereichs Produktionstechnik - Maschinenbau & Verfahrenstechnik (FB04)

Informationsveranstaltung zur Planung, Anmeldung und Anfertigung der Abschlussarbeit in den Studiengängen des Fachbereichs Produktionstechnik

Start from 7:45 p.m., please arrive on time. Afterwards there will be a practical fire extinguishing exercise in the outside area behind the SFG-Building, place outside in the Emmy-Noether-Straße. The participants are asked to pay attention to weatherproof clothing and sturdy shoes, because the fire drill takes place outside.

Currently, a traditional proton-membrane (PEM) electrolyser is used for the production of oxygen and hydrogen on the International Space Station (ISS) as part of the greater oxygen generator assembly (OGA). Due to its numerous malfunctions, unreliability and complex maintenance, the OGA is however not suitable for oxygen production on long-term space missions. In part, this is also because the PEM electrolyser requires an additional centrifuge system to remove the produced gas as the near-absence of buoyancy complicates gas-liquid phase separation. Gas-diffusion electrode systems are currently developed for terrestrial electrolysis systems, as they circumvent gas diffusion obstacles e.g., in simultaneous CO2 reduction and oxygen producing electrolysers. The project focuses on an energetic comparison between the PEM electrolyser system used on the ISS and a gas diffusion electrode arrangement for hydrogen and oxygen production in space environments.

The objective of this master project is the design, manufacturing, testing and validation of a small-scale wind tunnel. The purpose of this wind tunnel is to perform experiments of small wings: where the lift generated by different wing geometries, at different angles of attack is to be measured, and the flow visualized. Additionally you will use numerical methods to compute the theoretical lift force generated by the wings. You will use these simulations to validate your wind tunnel, and to compare the experimental and theoretical results. Thus this project is subdivided into four knowledge areas: (1) Numerical simulations using a (simple) potential flow method (2) Numerical simulations using OpenFoam (3) Measurement techniques and (4) CAD and assembly. It is therefore intended for 4 students with:

Ziel dieses Projekts ist die Auseinandersetzung mit Stereo-Vision
Kartierungsmethoden für (semi)autonome Mondrover. Relevante
Kartierungsmethoden sollen die Beschaffung des umgebenden
Terrains in Echtzeit kartieren und damit die Entwicklung von
autonomen Navigationsverhalten vorbereiten. Als Testplattform
dient ein Mikro-Rover, der im Projekt SAMLER-KI am DFKI RIC
entwickelt wird. Im Rahmen des Projekts steht der Student in allen
Phasen im engen Austausch mit Projektmitgliedern von SAMLER-
KI und muss seine Designentscheidungen und Designumsetzung
kommunizieren und abstimmen.

As part of the project, a semi-autonomous robot is to be developed
that masters the tasks of the European Rover Challenge, ERC
(http://roverchallenge.eu). The focus lies on several autonomous
and remotely operated tasks like navigation and mapping in a
fictitious Mars mission or soil sampling with a drilling mechanism.
The robot will be tested both in simulation and in reality. Depending
on the requirements of the challenge, existing hardware and
software of the DFKI Robotic Innovation Center can be used or
newly developed.
This is the second year in which we will apply to the ERC. During
the last edition we successfully completed the first phases of the
project as part of a systems engineering bachelor project, but we
did not pass the final selection. Currently, the rover has been
mostly designed (the team can perform any modification though),
and the construction is ongoing.
The students will perform tasks in the field of robotics, such as
intelligent obstacle avoidance or interaction through a robotic arm
with a control panel. Nevertheless, for the team to be successful in
the ERC, other work will be needed. An important aspect to be
considered is the capacity to produce detailed technical
descriptions of the work done and the rationale of the decisions
taken based on the requirements of the project. The evaluations
that lead to the acceptance or rejection of the team are highly
dependent on this. Another important aspect is the team
organization, which has to be comprehensive, resilient, sustainable,
and scalable.
Objectives of the project:
-
Understanding robotics as an interdisciplinary endeavor
involving electrical engineering, mechatronics and computer
science from the technical side but also with crucial
connections to business, communication, and team
management among others.
