In Zeiten von Industrie 4.0 und einer zunehmenden Automatisierung und Flexibilisierung der Produktion nimmt die Werkzeuglogistik eine zentrale Rolle ein. Der Einsatz mobiler Roboter bietet das Potenzial, eine durchgängige Automatisierung des Materialflusses von Werkzeugen herbeizuführen. Eine Implementierung der Systeme ist jedoch mit zahlreichen soft- und hardwareseitigen Herausforderungen verbunden, die insbesondere von kleinen und mittleren Unternehmen bewerkstelligt werden müssen.   Tool logistics takes a central role within the framework of industry 4.0 and the targeted automation and flexibility in production. The use of mobile service robots allows for a holistic automation of the material flow of tools. Implementing such systems is associated with numerous software and hardware challenges, to be managed in particular by small and medium-sized enterprises.

Mobile Service Robots

Although the wheeled locomotion proved to be very efficient on smooth grounds, it still encounters great difficulties in natural environments, where the ground is subject to wide variations in term of geometry (irregular surface, presence of obstacles...) and material properties (cohesion, grip condition...). This chapter presents recent developments and original systems that improve the capacities of wheeled mobile service robots on natural ground. First is considered the case of low speed motion. Section 2 presents recent results on reconfigurable suspensions that have two states and can decrease lateral friction and energy consumption during turns for skid-steering vehicles. Section 3 presents an original hybrid kinematics that combines wheels with an articulated frame for creating a mobile-wheeled robot with high obstacle-climbing capacities, using only one supplemental actuator. Other advances deal with high-speed motion. Section 4 describes a new device dedicated to vehicle dynamic stability, which improves lateral stability on fast mobile robots during turns and contributes to rollover prevention. Finally, Section 5 introduces innovative suspensions with two DOF for fast obstacle crossing. They damp vertical shocks, such as ordinary suspensions, but also horizontal ones, contributing to tip-over prevention on irregular grounds that feature many steep obstacles.

A review of the known and an indication of the new threats for cyber-physical robotic systems, caused by cybernetic attacks, serves, in this paper, as a basis for the analysis of the known methods relied upon to detect and mitigate consequences of such attacks. A particular emphasis is placed on threats specific for cyber-physical systems, as they are a feature distinguishing these systems from their traditional Information and Communication Technologies (ICT) counterparts. Based on the review of literature and own analyses, unresolved issues regarding the cyber-security of robot systems are presented and discussed.

This paper presents a new and practical method for mapping and annotating indoor environments for mobile robot use. The method makes use of 2D occupancy grid maps for metric representation, and topology maps to indicate the connectivity of the ‘places-of-interests’ in the environment. Novel use of 2D visual tags allows encoding information physically at places-of-interest. Moreover, using physical characteristics of the visual tags (i.e. paper size) is exploited to recover relative poses of the tags in the environment using a simple camera. This method extends tag encoding to simultaneous localization and mapping in topology space, and fuses camera and robot pose estimations to build an automatically annotated global topo-metric map. It is developed as a framework for a hospital service robot and tested in a real hospital. Experiments show that the method is capable of producing globally consistent, automatically annotated hybrid metric-topological maps that is needed by mobile service robots.
