* Movement recognition using modern computer vision techniques * Processing of audio signals obtained from the microphone * Organization and preparation of meetings and contact with the customer * Planning and allocation of tasks

* Exploration of velocity dependency of vibration signals recorded from hard surfaces using an acceleration sensor * Signal processing: recording of signals, filtering, segmentation * Signal analysis using spectral and temporal features * User study to investigate if a change in velocity is percieved by human senses * Development of an experiment environment in Visual Studio/C++ and OpenCV and an evaluation device on a breadboard

* Extension of the path-planner by dynamic starting point allocation * The development framework was the Robot Operating System (ROS Indigo) * Data from sensors delivered in rosbags * For the implementation of the image processing algorithms the OpenCV library was used

* Development of a web interface for an industrial calculator of cavitational losses in hydraulic systems * Front-end development using HTML/CSS/JavaScript (jQuery)
