LEROSH: robotics in the craft
I'm currently spending most of my time helping artisans to use collaborative robots to create unique artifacts (project
LEROSH).
To ensure that components can be individually manufactured with the necessary efficiency, LEROSH relies on advanced sensor technology and machine learning and thus on optimization and flexibility in the sanding application – up to ‘ad-hoc automation’ of recurring, similar and even individual tasks. For the intuitive usability LEROSH is equally focused on developing new UI/UX elements that empower users to independently control and improve their processes.

phd thesis: human-scale personal fabrication
my research focused on adressing the challenges of building human-scale structures (static, kinematic, and dynamic ones), with minimal engineering knowledge and using comoddity equipment only.advised by prof. Patrick Baudisch at the Hasso Plattner Institute - Human Computer Interaction lab.

TrussFab: Fabricating Sturdy Large-Scale Structures on Desktop 3D Printers
CHI’17Robert Kovacs, Anna Seufert, Ludwig Wall, Hsiang-Ting Chen, Florian Meinel, Willi Müller, Si-jing You, Maximilian Brehm, Jonathan Striebel, Yannis Kommana, Alexander Popiak, Thomas Bläsius, and Patrick Baudisch TrussFab is an integrated end-to-end system that allows users to fabricate large scale structures that are sturdy enough to carry human weight. TrussFab achieves the large scale by complementing 3D print with plastic bottles.Protopiper: Physically Sketching Room-Sized Objects at Actual Scale
UIST ‘15Harshit Agrawal, Udayan Umapathi, Robert Kovacs, Johannes Frohnhofen, Hsiang-Ting Chen, Stefanie Mueller, Patrick Baudisch Protopiper is a computer aided, hand-held fabrication device that allows users to sketch room-sized objects at actual scale. The key idea behind protopiper is that it forms adhesive tape into tubes as its main building material, rather than extruded plastic or photopolymer line.

Haptic PIVOT: On-Demand Handhelds in VR
UIST’20Robert Kovacs, Eyal Ofek, Mar Gonzalez Franco, Alexa Fay Siu, Sebastian Marwecki, Christian Holz, Mike Sinclair
PIVOT is a wrist-worn haptic device that renders virtual objects into the user’s hand on demand. Its simple design comprises a single actuated joint that pivots a haptic handle into and out of the user’s hand, rendering the haptic sensations of grasping, catching, or throwing an object – anywhere in space.

Kyub: a 3D Editor for Modeling Laser-Cut Objects
CHI‘19 Patrick Baudisch , Arthur Silber, Yannis Kommana, Milan Gruner, Ludwig Wall, Kevin Reuss, Lukas Heilman, Robert Kovacs, Daniel Rechlitz, and Thijs Roumen Kyub is an interactive editing system for laser cutting. Unlike earlier systems, kyub affords constructing closed box structures by stacking cubic shaped primitives –boxels. This interaction provides the strong affordance and ease of use of a voxel-based editor, while building with boxels ensures the structural stability.
Fastforce: Real-Time Reinforcement of Laser-Cut Structures
CHI‘20Muhammad Abdullah, Martin Taraz, Yannis Kommana, Shohei Katakura, Robert Kovacs, Jotaro Shigeyama, Thijs Roumen, and Patrick Baudisch
fastForce is a software tool that detects structural flaws in laser cut 3D models and fixes them by introducing additional plates into the model. It fixes structural issues in real-time, while users stay focused on editing their models and without ever becoming aware of any structural issues.

FormFab: Continuous Interactive Fabrication
TEI‘19 Stefanie Mueller, Anna Seufert, Huaishu Peng, Robert Kovacs, Kevin Reuss, François Guimbretière, Patrick Baudisch FormFab is an interactive fabrication system that can change a workpiece’s shape continuously while the user is interacting. This enables users to explore different sizes of a shape with a single interaction rather than in multiple turns. We accomplish this using a process called formative fabrication, which rather than adding or subtracting, reshapes the existing material. In our system, users interactively control a pneumatic air pump that applies either pressure or vacuum to a compliant thermoplastic sheet, thereby pushing the material outwards or pulling it inwards.
Patching Physical Objects
UIST ‘15 Alexander Teibrich, Stefanie Mueller, François Guimbretière, Robert Kovacs, Stefan Neubert, and Patrick Baudisch Personal fabrication is currently a one-way process: once an object has been fabricated with a 3D printer, it cannot be changed anymore. In this paper, we propose a different approach: instead of re-printing the entire object from scratch, we suggest patching the existing object to reflect the next design iteration.metamaterial mechanisms
Metamaterial Textures
CHI‘18 Alexandra Ion, Robert Kovacs, Oliver S. Schneider, Pedro Lopes, and Patrick Baudisch Metamaterial textures are 3D printed surface geometries that can perform a controlled transition between two or more textures. Metamaterial textures are integrated into 3D printed objects and allow designing how the object interacts with the environment and the user’s tactile sense.
Metamaterial Mechanisms
UIST ‘16 (best paper honorable mention)
Alexandra Ion, Johannes Frohnhofen, Ludwig Wall, Robert Kovacs, Mirela Alistar, Jack Lindsay, Pedro Lopes, Hsiang-Ting Chen, and Patrick Baudisch So far, metamaterials were understood as materials—we want to think of them as machines. We demonstrate metamaterial objects that perform a mechanical function.

DualPanto: a Haptic Device That Enables Blind Users to Continuously Interact with Virtual Worlds
UIST‘18 Oliver Schneider, Jotaro Shigeyama, Robert Kovacs, Thijs Jan Roumen, Sebastian Marwecki, Nico Boeckhoff, Daniel Amadeus Gloeckner, Jonas Bounama, Patrick Baudisch DualPanto is a haptic device that enables blind users to continuously track the absolute position of moving objects in spatial virtual environments, as is the case in sports or shooter games.
Linespace: a Sense Making Platform for the Blind
CHI‘16 Saiganesh Swaminathan, Thijs Roumen, Robert Kovacs, David Stangl, Stefanie Mueller, Patrick Baudisch Linespace is a tactile display system for blind users. The foundation of our system is a large 140x100cm display area, on which the system creates raised tactile lines with the help of a 3D printer. The foot switch allows users to enter text and issue commands by talking to the computer.haptic feedback in virtual reality
Level-Ups: Motorized Stilts that Simulate Stair Steps in Virtual Reality

UIST‘15 Lung-Pan Cheng, Thijs Roumen, Hannes Rantzsch, Sven Köhler, Patrick Schmidt, Robert Kovacs, Johannes Jasper, Jonas Kemper, and Patrick Baudisch TurkDeck is an immersive virtual reality system that reproduces not only what users see and hear, but also what users feel. TurkDeck creates these physical representations on the fly by making a group of human workers present and operate the props only when and where the user can actually reach them.cyber security

ad infinitum: a parasite that lives off human energy
Ars Electronica Linz & Science Galery DoublinPedro Lopez, Robert Kovacs, Alexandra Ion, David Lindlbauer, and Patrick Baudisch
Ad infinitum is a parasitical entity which lives untethered and off the grid. This parasite reverses the dominant role that mankind has with respect to technologies: the parasite shifts humans from “users” to “used” .
pendulum tuning
Museum Kiscell, Budapest, Hungary Turcsany Villő - artistRobert Kovacs - motion systems
The installation makes an attempt to change the personal perception of time. Four kinetic sculptures are suspended at the highest point of the temple space, allowing them to make pendulum movement. Their design represents advancement against the physical drag. The pendulums’ paths develop a moving structure and create a rhythm; they are constantly changing and thus re-tuneing the space of the viewer.
