In this paper we presents the design of the dexterous DLR Hand II and experiments performed with it so far. In various experiments and demonstrations we could show the abilities of our articulated hand and gain a lot of experience in what artificial hands can do, what abilities they need and where their limitations lie. We discuss the achievements and the… (More)
The paper describes recent design and development efforts in DLR`s robotics lab towards a new generation of " mechatronic " ultra-light weight robots with articulated hands and high-level remote programmability. The design of fully sensorized robot joints with complete state feedback and the underlying mechanisms are outlined. The second lightweight arm… (More)
For efficient analysis of large smart city data sets in (real) time a knowledge-based approach is suggested, constraining iteratively the search space while increasing accuracy by more complex computation. Results are shown for searching the distance to the nearest object, e.g., parking space.
Software testing is the most important and most time-and cost consuming part in the software development process. According to  about 50% of the resources in a software project are spent for testing. Often, research activities, with the goal to automatise this process, cover only the generation of test cases and their execution. The important topic of… (More)
This paper presents a framework for processing the data generated by Smart City sensors and IoT data streams in real-time. The scope of processing is to detect various event patterns from the raw data. The framework is extensible because at any moment new data sources can be registered or new specific event detection mechanism can be deployed. The framework… (More)
Due to renewable energies, the feed-in to the power grid will fluctuate increasingly. As long as no highly efficient storage technology is found, the importance of demand side management (DSM) will grow. Different algorithms have been proposed for managing the consumers. However, they cannot be easily compared due to a lot of different assumptions while… (More)
Reliable information processing is an indispensable task in Smart City environments. Heterogeneous sensor infrastructures of individual information providers and data portal vendors tend to offer a hardly revisable information quality. This paper proposes a correlation model-based monitoring approach to evaluate the plausibility of smart city data sources.… (More)
