Technologies of missions’ generation for the mobile robots (MR) Amur-307 by the parallelized automatic scheduler and their implementation by the integration software (SW) with the hardware block (HB) on 6 power channels (6x30A), with the branched sensorics are considered. The program generator is forming the tasks in the PDDL language based on the route map in vector graphic format, parameters of objects moved by robots, and equipment installed on robots. The developed plan is implemented by the HB and the navigation control program, based on topological information extracted from the map, based on passive oriented visual markers installed in the walls. The robot can work both in real and in virtual environments, using the Webots emulator and/or relying on its own original developments.

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.
