About
Georg Nawratil is a leading researcher in the kinematics and robotics of parallel manipulators, with a particular focus on singularity analysis, performance indices, and haptic interaction. His work has fundamentally advanced the understanding of how to measure and avoid singularities in robotic systems, which is crucial for safe and efficient path planning. For instance, his 2019 paper on "Singularity Distance for Parallel Manipulators of Stewart Gough Type" (9 citations) and his 2024 work on "Singularity distance computations for 3-RPR manipulators using intrinsic metrics" (4 citations) provide novel algorithms for detecting the closest singularity to a given pose, using intrinsic metrics based on elastic strain energy. Nawratil has also made significant contributions to performance evaluation, introducing new indices for 6-dof UPS and 3-dof RPR parallel manipulators (2008, 18 citations) and for 6R robots (2007, 16 citations). More recently, he has pioneered the use of action-origami in haptic devices for virtual reality, as demonstrated in his 2023 paper (6 citations) on "Action-Origami Inspired Haptic Devices for Virtual Reality," which offers innovative, minimally actuated haptic feedback. With over 80 citations across his most-cited works, Nawratil’s research bridges theoretical kinematics and practical robotics, making him a key figure in the field.
