The importance of legged robots is emphasized, as legged robot locomotion allows highly precise performance and wide spectrum of application, even in rough, unstructured terrain. However, the present challenges in legged robot locomotion are the trade-off between versatility and robustness, and the …

An accurate, up-to-date estimation of it's own pose is important for any mobile robot that should be able to navigate in and/or interact with the physical world. While there are many methods of pose estimation, they are often lacking in one or more specific aspects. In particular, they may be inaccu…

The aim of this study was to implement a machine learning classifier for infant EEG data. Similar classifiers for adults are commonly utilized by brain-computer-interfaces. Three experiments were conducted to test our implementation, with the goal of classifying standard versus deviant/target stimul…

DFKI is setting up a motor test bench to characterize the robotic drives developed in-house. The measurement can be influenced by torsional vibrations and alignment errors. Therefore, it is necessary to analyze the setup mechanically to minimize the measurement errors. For this purpose, the natural …

Unmanned surface vehicles (USVs) are boats that can navigate on the water surface without theneed for a human operator on board. Since there are many disturbances and nonlinear effects due tothe hydrodynamics of water, there is a need for robust motion control systems. Reinforcementlearning provides…

Structural analysis of any arbitrary component demands a representation of the structural relevant subassemblies in a finite element mesh. For Coyote III this mesh is generated by considering the available mesh element types and their benefits in different fields of application. The quality of the r…

In der robotischen Forschung entstehen große Mengen an komplexen Log- und Experimentdaten. In der Praxis existieren allerdings oft keine einheitlichen Dateninfrastrukturen um diese angemessen zu archivieren und für die Auswertung und weitere Forschung bereit zu stellen. Aus diesem Grund werden in di…

The sim-to-real gap represent a very important issue in the robotics research field. Challenging problems like the stabilization of highly chaotic underactuated systems are very sensitive to changes with respect to the simulated environment. Region of attraction (RoA) estimation gives an intuitive p…

Texture and shape recognition through applying haptic sensors are being widely explored in robotics. Various technologies, such as vibrations, force feedback, air vortex rings, and ultrasound, are used in haptic sensing. However, the implementation of this kind of sensor may be limited, especially i…
