Biography


I am a Ph.D. student at the Robotics and Perception Group led by Prof. Davide Scaramuzza since December 2012. Currently, I am working on agile flight for vision-based quadrotors. I received my Bachelor's and my Master's degree in mechanical engineering from ETH Zürich in 2010 and 2012, respectively. During my studies at ETH, I was focusing on robotics and control.

Master Thesis: Modeling, Control and Trajectory Tracking with a CoaX Helicopter

SPHERES VERTIGO

I accomplished my Master thesis as part of a ten month stay at the GRASP Lab at the University of Pennsylvania. There, I was working with Vijay Kumar on the modeling and control of small coaxial helicopters. Specifically, the project included the development of the framework that enables autonomous flight in a Vicon motion capture system using ROS (Robot Operating System) and Matlab. Then, I extended existing mathematical models in order to capture the helicopter's dynamics more accurately, especially in nonhover conditions. With the extended model, I designed a novel nonlinear controller, which allows following trajectories with large accelerations. Finally, I implemented a first approach of a method for generating smooth trajectories, which can also deal with obstacles in the flight path.

Semester Thesis: Estimation of Ball Coefficient of Restitution for the Blind Juggler

Robotic calligraphy

During my Master studies, I completed my semester thesis in Raffaello D'Andrea's research group at ETH Zurich. I worked with the Blind Juggler, which is a robot that can vertically juggle a ball without any sensing of the ball. My work involved the development of a measurement setup in order to identify parameters of the impact model. I then used the identified parameters to compute juggling paddle motions that allow aggressive changes of the juggling height while minimizing the required paddle stroke.
