Biography


I am a PhD student at the Robotics and Perception Group led by Prof. Davide Scaramuzza. Currently, I am working on event-based vision for high-speed robotics and air-ground robot collaboration. In 2010 and 2012, I received my Bachelor's and Master's degree in Mechanical Engineering from ETH Zurich, respectively. During my studies at ETH, I was focusing on robotics, dynamics, and computer vision. I wrote my Master thesis at MIT under the supervision of Prof. John J. Leonard on visual SLAM for space applications.

Research Interests


Event-based Robot Vision

Unlike a standard CMOS camera, a DVS does not wastefully send full image frames at a fixed frame rate. Conversely, similar to the human eye, it only transmits pixel-level brightness changes at the time they occur with microsecond resolution, thus, offering the possibility to create a perception pipeline whose latency is negligible compared to the dynamics of the robot. We exploit these characteristics to estimate the pose of a quadrotor with respect to a known pattern during high-speed maneuvers, such as flips, with rotational speeds up to 1,200 degrees a second. We presented our work at the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in 2014. It was also featured on IEEE Spectrum.

Air-Ground Collaboration

 We develop strategies for aerial and ground robots to work together as a team. By doing so, the robots can profit from each others capabilites. Our demonstration won the KUKA Innovation Award 2014 and was presented in a paper at the IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR) in 2014.

Happy Easter

 

We released this video on Easter 2013. A quadrotor is flying above a ground robot while looking for Easter eggs that lie on the ground. It then tells the ground robot the exact position of these eggs, so that all of them can be collected. This video was accepted for the video session at the International Joint Conference on Artificial Intelligence (IJCAI) 2013 in Beijing, China.

Master Thesis: Visual Mapping of Unknown Space Targets for Relative Navigation and Inspection

SPHERES VERTIGO

During my Master thesis at the Computer Science and Artificial Intelligence Lab (CSAIL) at MIT under the supervision of Professor John Leonard, I implemented a visual mapping algorithm that is capable of creating a 3D model of an unknown and uncooperative space target, e.g. a satellite, using a stereo camera. The code was tested aboard the International Space Station (ISS). This algorithm will later be used for relative navigation, inspection, and docking maneuvers in space.

Semester Thesis: Robotic calligraphy - A robot that learns how to write Chinese calligraphy

Robotic calligraphy

I wrote my Semester thesis at the Institute of Dynamic Systems and Control at the ETH Zurich about robotic calligraphy. During this project, I implemented a trajectory generator that enabled the robot to draw Chinese characters, used computer vision algorithms to compare the drawn characters with a reference from a textbook, and applied an iterative learning controller to improve the robot's next drawing.
