## Academic ### Local Map Optimization for Visual Inertial Mapping ##### Master Thesis A long term goal for autonomous robot research is to develop an accurate localisation technique based on visual data. To do so in a large environment, a large global map has to be constructed. Also for other reasons, but mainly when updating the global map with new data, the visual map needs a readjustment optimising the 3D structure to the measurements. To limit time and computational size, I implemented and analysed a local optimisation method as an alternative to a global optimisation. The thesis was written at the [Autonomous System Lab](http://www.asl.ethz.ch) of Prof. Roland Siegwart. The research was maintained in collaboration with [Google Project Tango](https://www.google.com/atap/project-tango/). ![Visual Inertial Mapping](/assets/VIMap.jpg) - ### Kalman-Filter Enhanced Iterative Learning Control ##### Semester Thesis Making use of a repeated control task, the information of the experienced error can be used to improve the controller performance dramatically. My semester thesis consisted of finding a mathematical formulation that allows a comparison of two approaches and an analysis of the differences. As part of my master degree at ETH Zürich, I wrote my semester thesis during an exchange semester at the [Dynamic System Lab](http://schoellig.name) of Prof. Angela Schoellig in University of Toronto's Institute for Aerospace Studies.

As a bachelor thesis, I developed an optical setup that made use of the Schlieren visualization technique to visualise the standing ultrasonic waves that were produced inside of a water filled 20x20x2mm transparent plastic box with piezo actuators. The Research was performed in Prof. Jürg Dual's [Mechanics and Experimental Dynamics Group](http://www.zfm.ethz.ch/e/exp-dyn/) at the Institute for Mechanical Systems of ETH Zürich, supervised by Dr. Dirk Möller Publication: [Article in Journal of Nanobiotechnology 2013, 11:21](http://www.jnanobiotechnology.com/content/11/1/21/) ![Schlieren Imaging](/assets/schlieren.png) - ### Studies in Mechanical Engineering, Control Systems and Robotics ##### Master of Science in Mechanical Engineering from ETH Zürich. My studies were part of the mechanical engineering program but focused largely on robotics, system and control classes. * Control Theory * System Modeling * Analysis and Linear Algebra * Classical mechanical engineering such as fluid dynamics, thermodynamics, construction structural mechanics etc. * Spacecraft Dynamics * Recursive Estimation (Kalman Filters) * Dynamic Programming and Optimal Control +
