An anthropomorphic hand arm system using variable stiffness actuation has been developed at DLR. It is aimed to reach its human archetype regarding size, weight and performance. The main focus of our development is put on robustness, dynamic performance and dexterity. Therefore, a paradigm change from impedance controlled, but mechanically stiff joints to(More)
INTRODUCTION In the context of an increasing number of multi-centric studies providing data from different sites and sources the necessity for central data management (CDM) becomes undeniable. This is exacerbated by a multiplicity of featured data types, formats and interfaces. In relation to methodological medical research the definition of central data(More)
Walking is a fascinating way of locomotion that is very robust, especially in unstructured terrain. Many researchers devote their time to understanding its underlying principles and to build robots based on their findings. Using the fingers of DLR-Hand II a six-legged actively compliant walking robot is developed. It is intended to be used as testbed for(More)
Individualized Medicine aims at providing optimal treatment for an individual patient at a given time based on his specific genetic and molecular characteristics. This requires excellent clinical stratification of patients as well as the availability of genomic data and biomarkers as prerequisites for the development of novel diagnostic tools and(More)
Peer-to-Peer (P2P) file sharing generates by far the most Internet traffic reaching up to 70 % in some regions of the world. These data volumes pose a significant challenge to Internet Service Providers (ISPs) regarding traffic engineering. Because P2P routing is usually agnostic of the underlying topology, traffic engineering abilities of ISPs are(More)
The paper presents a new torque-controlled lightweight robot for medical procedures developed at the Institute of Robotics and Mechatronics of the German Aerospace Center. Based on the experiences in lightweight robotics and anthropomorphic robotic hands, a small robot arm with 7 axis and torque-controlled joints tailored to surgical procedures has been(More)
Robotic surgery systems are highly complex and expensive pieces of equipment. Demands for lower cost of care can be met if these systems are employable in a flexible manner for a large variety of procedures. To protect the initial investment the capabilities of a robotic system need to be expandable as new tasks arise.
Today, an increasing number of customers subscribes for a high bandwidth internet access. But not only speed is demanded. Reliability, availability, and security move more and more into the customers focus. Carriers and Internet Service Providers, too, have increasing requirements derived from new services they want to offer to their customers or use(More)
Today, an increasing number of customers subscribes for a high bandwidth Internet access. But not only communication speed is demanded. Quality-of-service moves more and more into the customers' focus. Both carriers and Internet Service Providers (ISPs) have increasing requirements derived from new services they want to offer to their customers. We present(More)
Internet service providers (ISPs) have to store session data of their customers for operation, management, and control tasks. Thereby, each access node (AN) of an ISP’s access network keeps track of session data (e.g., IP addresses, MAC addresses, and lease times of IP addresses) of all connected customers. Session data is highly volatile due to continuous(More)
