Being part of the RoboCup initiative, the ROBOCUP@HOME league targets the development and deployment of autonomous service and assistive robot technology being essential for future personal domestic applications. The domain of domestic service and assistive robotics implicates a wide range of possible problems. The primary reasons for this include the large(More)
To put more emphasis on real-world problems, the authors propose to extend the RoboCup competitions. In order to foster progress in the desired abilities the authors propose to expand the existing challenges by a set of simple tests. The passing of the entire set should lead to robots that are capable of working both autonomously and in cooperation with(More)
For quick access to new handwritten collections, current handwriting recognition methods are too cumbersome. They cannot deal with the lack of labeled data and would require extensive laboratory training for each individual script, style, language, and collection. We propose a biologically inspired whole-word recognition method that is used to incrementally(More)
In this paper, we describe the structure and the performance of a layout analysis system developed for processing the handwritten documents contained in a large historical collection of very high importance in the Netherlands. We introduce a method based on contour tracing that generates curvilinear separation paths between text lines in order to preserve(More)
Benchmarking robotic technologies is of utmost importance for actual deployment of robotic applications in industrial and every-day environments, therefore many efforts have recently focused on this problem. Among the many different ways of benchmarking robotic systems, scientific competitions are recognized as one of the most effective ways of rapid(More)
Slant is one of the characteristics that make handwriting harder to process automatically than printed text. For this reason slant correction is a standard step in systems for processing written text. In this article I will present an algorithm for automatically correcting slant. It works by first segmenting the text into words using horizontal and vertical(More)
One of the long term objectives of robotics and artificial cognitive systems is that robots will increasingly be capable of interacting in a cooperative and adaptive manner with their human counterparts in open-ended tasks that can change in real-time. In such situations, an important aspect of the robot behavior will be the ability to acquire new knowledge(More)
The dynamical and uncertain environments of domestic service robots, which include humans, require rethinking of the benchmarking principles for testing these robots. Since 2006 RoboCup@Home has used statistical procedures to track and steer the progress of domestic service robots. This paper explains the procedures and shows outcomes of these international(More)
