“…This includes embedded realtime architectures [2,5,[14][15][16][17], real-time vision [2,[14][15][16][17], learning and adaptation from limited sensor data, skill learning and methods to propagate learned skills and behaviors in the robot team [13,12,9]. However, our goal is not to carry out research for specific solutions in the robotic soccer domain, but to use and test advanced techniques from different research projects.…”

Abstract:The Paderkickers are a robot soccer team that makes heavy use of automotive technology Uke C167 micro-controllers or communication over CAN bus. All sensor data is processed on these decentralized embedded nodes to yield a high degree of reliability and hardware layer abstraction. In this paper, we describe how the complex system copes with perception and action in real-time and integrates it in the higher strategy layer to achieve autonomous behavior.

Distribution of functionality among nodes is a contemporary research issue for embedded systems, e.g. in the field of autonomous mobile robot groups. In such groups, the concept of distribution is mainly used to achieve flexibility and robustness that could not be reached by a single robot. Here it will be used as a design-paradigm for a robot's internal architecture. In this paper, a hierarchically distributed robot architecture will be introduced which leads to an improved autonomy of the overall system.

This special issue, entitled "Object-oriented Real-time Distributed Computing", contains six papers that are based on a selection out of the papers that had been presented at the 6th IEEE International Symposium on Object-oriented Real-time distributed Computing (ISORC 2003) and the 9th IEEE International Workshop on Object-oriented Real-time Dependable Systems (WORDS 2003F). For publication in this issue, the original papers had to undergo further review. Their contents had been refined, expanded, and updated.The purpose of the ISORC and WORDS series is to analyze and discuss recently established or newly emerging trends in the evolution of the object-oriented real-time distributed computing (ORDC) technology and to identify challenging research issues as well as the projected directions for future evolution. Following this spirit, the papers in this issue cover a wide range of ORDC topics, including an online hardware feasibility test scheme for thread admission control in the multithreaded Java microcontroller developed in the Komodo project (Brinkschulte, 2003), a non-blocking buffer mechanism which can facilitate communication of event messages from a producer to a consumer without causing any party to experience blocking (Kim, 2003), a fault-tolerant approach to handle transient upsets of multiple components in a TTA (Time-Triggered Architecture) system (Steiner et al., 2003), an exception handling framework for mobile agent systems to operate in the presence of agent server crash failures (Xu and Pears, 2003), two strategies to better estimate the bound for the worst-case execution time (WCET) of a code, that is, a programming strategy (WCET-oriented programming) and a code transformation strategy (the single-path conversion technique) (Gustafsson et al., 2003), and a system named VisiTrack for video based incremental tracking on mobile devices (Stichling et al., 2003). These papers do not only show how important the ORDC technology is in various applications, but they also present interesting problems in the current ORDC technology that may open up new areas of research in the future.The first paper, "Scalable Online Feasibility Tests for Admission Control in a Java Real-Time System" by Uwe Brinkschulte, describes fast online feasibility tests for thread admission control to prevent processor overload in the multithreaded Java microcontroller. A main scheduling policy, Guaranteed Percentage (GP) scheduling, is proposed and realized by hardware in the microcontroller core. This scheme assigns each thread a guaranteed percentage of the processor power, thus providing a strict isolation of the threads on the processor. To prevent processor overload in the dynamic Java environment, fast online feasibility tests are necessary before a new thread is allowed to enter the microcontroller. Based on the processor demand analysis, a new test called as the periodic transformation analysis is proposed. This test is sufficient and scalable. Furthermore, the modified version, the reduced periodic transformation analy...
