    Autonomous Off-Road Navigation for MuCAR-3
    (KI - Künstliche Intelligenz: Vol. 25, No. 2, 2011) Himmelsbach, Michael; Luettel, Thorsten; Hecker, Falk; Hundelshausen, Felix; Wuensche, Hans-Joachim
    This report gives an overview of the autonomous navigation approach developed for the ground robot MuCAR-3, partly as a satellite project in the CoTeSys cluster of excellence. Safe robot navigation in general demands that the navigation approach can also cope with situations where GPS data is noisy or even absent and hence great care must be taken when using global map information. Choosing a safe action should be tightly coupled to the perception of the immediate surrounding in such situations. The tentacles approach developed earlier in the project efficiently deals with these issues by introducing integral structures for sensing and motion. This report presents the extensions and improvements made to the tentacles approach during the progress of the project and the results obtained at various challenging robot competitions.

    From RoboCup Rescue to Supervised Autonomous Mobile Robots for Remote Inspection of Industrial Plants
    (KI - Künstliche Intelligenz: Vol. 30, No. 0, 2016) Kohlbrecher, Stefan; Stryk, Oskar von
    With increasing capabilities and reliability of autonomous mobile robots, inspection of remote industrial plants in challenging environments becomes feasible. With the ARGOS challenge, oil and gas company TOTAL S.A. initiated an international competition aimed at the development of the first autonomous mobile robot which can safely operate in complete or supervised autonomy over the entire onshore or offshore production site, potentially in hazardous explosive atmospheres and harsh conditions. In this work, the approach of joint Austrian–German Team ARGONAUTS towards solving this challenge is introduced, focussing on autonomous capabilities. These build on functional components developed during prior participation in the RoboCup Rescue Robot League.

    Knowledge-Based Instrumentation and Control for Competitive Industry-Inspired Robotic Domains
    (KI - Künstliche Intelligenz: Vol. 30, No. 0, 2016) Niemueller, Tim; Zug, Sebastian; Schneider, Sven; Karras, Ulrich
    Autonomy is an increasing trend in manufacturing industries. Several industry-inspired robotic competitions have been established in recent years to provide testbeds of comprehensible size. In this paper, we describe a knowledge-based instrumentation and control framework used in several of these competitions. It is implemented using a rule-based production system and creates the task goals for autonomous mobile robots. It controls the environment’s agency using sensor data from processing stations and instructs proper reactions. The monitoring and collection of various data allows for an effective instrumentation of the competitions for evaluation purposes. The goal is to achieve automated runs with no or as little human intervention as possible which would allow for more and longer lasting runs. It provides a general framework adaptable to suit many scenarios and is an interesting test case for knowledge-based systems in an industry-inspired setting.
