Gathering mobile robots is a widely studied problem in robotic research. This survey first introduces the related work, summarizing models and results. Then, the focus shifts on the open problem of gathering fat robots. In this context, “fat” means that the robot is not represented by a point in a bidimensional space, but it has an extent. Moreover, it can be opaque in the sense that other robo...

Today internet has made the life of human dependent on it. Almost everything and anything can be searched on net. Web pages usually contain huge amount of information that may not interest the user, as it may not be the part of the main content of the web page. Web Usage Mining (WUM) is one of the main applications of data mining, artificial intelligence and so on to the web data and forecast t...

Children with autism spectrum disorder (ASD) have deficits in the socio-communicative domain and frequently face severe difficulties recognition expression of emotions. Existing literature suggested that children ASD benefit from robot-based interventions. However, studies varied considerably participant characteristics, applied robots, trained skills. Here, we reviewed interventions targeting ...

Acknowledgments First of all, I wish to thank my advisor Armin B. Cremers for his guidance, encouragement, and patience. I thank Wolfram Burgard for his willingness to be the co-referent. I am grateful to both of them for offering me the opportunity to work on the Robotic Tele-Presence Lab (RTL) Project, a part of KI-NRW/Virtual Knowledge Factory, headed by Armin B. Cremers and Wolfram Burgard,...

Intelligent robots frequently need to understand requests from naive users through natural language. Previous approaches either cannot account for language variation, e.g., keyword search, or require gathering large annotated corpora, which can be expensive and cannot adapt to new variation. We introduce a dialog agent for mobile robots that understands human instructions through semantic parsi...

The robotics is one of the most active areas. We also need to join a large number of disciplines to create robots. With these premises, one problem is the management of information from multiple heterogeneous sources. Each component, hardware or software, produces data with different nature: temporal frequencies, processing needs, size, type, etc. Nowadays, technologies and software engineering...

Many roboticists rely on simulation during the early phases of developing navigation algorithms for their autonomous mobile robots. While many commercial robots now come with robust development environments that include visual simulators, these tools aren’t available to robotics researchers who are working with a custom-built robot or who have not yet determined which commercial robot will sati...

The development of teleoperated autonomous robots occurred due the existence of environments unsuitable for human action. These robots usually need a representation of the environment (a map) and the capacity to interpret that representation to be able to plan a path towards some target location and to move safely in an environment where there may be variations in the position of the objects. T...

The use of autonomous robots in both industry and every day life has increased significantly in the recent years. A growing number of robots is connected to and operated from networks, including the World Wide Web. Consequently, the Robotics community is exploring and adopting REST (Representational State Transfer) architectural principles and considers the use of Linked Data technologies as fr...
