Social robots’ software is commonly tested in a simulation due to the safety and convenience reasons as well as an environment configuration repeatability assurance. An interaction between a robot and a human requires taking a person presence and his movement abilities into consideration. The purpose of the article is to present the HuBeRo framework, which can be used to simulate human motion behaviour. The framework allows independent control of each individual’s activity, which distinguishes the presented approach from state-of-the-art, opensource solutions from the robotics domain. The article presents the framework assumptions, architecture, and an exemplary application with respect to presented scenarios.

Convenient human-computer interaction is essential to carry out many exhausting and concentration-demanding activities. One of them is cyber-situational awareness as well as dynamic and static risk analysis. A specific design method for a multimodal human-computer interface (HCI) for cyber-security events visualisation control is presented. The main role of the interface is to support security analysts and network operators in their monitoring activities. The proposed method of designing HCIs is adapted from the methodology of robot control system design. Both kinds of systems act by acquiring information from the environment, and utilise it to drive the devices influencing the environment. In the case of robots the environment is purely physical, while in the case of HCIs it encompasses both the physical ambience and part of the cyber-space. The goal of the designed system is to efficiently support a human operator in the presentation of cyberspace events such as incidents or cyber-attacks. Especially manipulation of graphical information is necessary. As monitoring is a continuous and tiring activity, control of how the data is presented should be exerted in as natural and convenient way as possible. Hence two main visualisation control modalities have been assumed for testing: static and dynamic gesture commands and voice commands, treated as supplementary to the standard interaction. The presented multimodal interface is a component of the Operational Centre, which is a part of the National Cybersecurity Platform. Creation of the interface out of embodied agents proved to be very useful in the specification phase and facilitated the interface implementation.

The paper presents the Embodied Agent-based Robot control system modelling Language (EARL). EARL follows a Model-Driven Software Development approach (MDSD), which facilitates robot control system development. It is based on a mathematical method of robot controller specification, employing the concept of an Embodied Agent, and a graphical modelling language: System Modelling Language (SysML). It combines the ease of use of SysML with the precision of mathematical specification of certain aspects of the designed system. It makes the whole system specification effective, from the point of view of the time needed to create it, conciseness of the specification and the possibility of its analysis. By using EARL it is possible to specify systems both with fixed and variable structure. This was achieved by introducing a generalised system model and presenting particular structures of the system in terms of modelling block configurations adapted by using instances. FABRIC framework was created to support the implementation of EARL-based controllers. EARL is compatible with component based robotic middlewares (e.g., ROS and Orocos).

Echocardiography is the most commonly used imaging technique in clinical cardiology. Due to the high demand for this type of examination and the small number of specialists, there is a need to support the examination process through telemedicine. Moreover, specialist training can be supported by appropriate simulation systems. For (i) creating tailor-made tele-echo robots, (ii) creating echo system simulators, and (iii) conducting echo examination with local or remote expert assistance, knowledge about echo probe kinesthetic parameters during echocardiography examination is advisable. The article describes the concept of a measuring system for obtaining such data.

The technical capabilities of robots and their increased versatility require a single robot to be able to perform a wide array of complex tasks. What more, when performing a task, it may be asked to carry out another one. Switching between different tasks is a known problem in engineering, however, robots, compared to programs operating in a virtual space, are unique as they must follow laws of physics. In this work, we introduce a method for harmonising service robot tasks being managed by finite state machines. The method allows for the handling of safe suspend and resume procedures for a complex task. Additionally, we consider a case when the robot can not switch the current task to another at any time. The method was implemented and verified by conducting multiple interruptions of one task by another one. The tasks during the verification were being performed in simulation by a TIAGo robot.

Jednym z podejść do specyfikacji sterowników robotów jest teoria agenta upostaciowionego zakładająca podział systemu robotycznego na grupę komunikujących się ze sobą agentów. Każdy agent złożony jest z podsystemów, których działanie opisuje się przy pomocy funkcji przejść. W artykule został zaproponowany nowy sposób dekompozycji funkcji przejścia podsystemu agenta upostaciowionego. W odróżnieniu od dotychczasowego podejścia koncentrującego się na podziale funkcji ze względu na produkowane wyjścia, autorzy dokonują podziału ze względu na cel prowadzonych obliczeń. To podejście umożliwia scalenie powtarzających się elementów specyfikacji, przez co opis staje się krótszy i prostszy. Artykuł stanowi też próbę zestawienia poszczególnych elementów wchodzących w skład agenta upostaciowionego z metodami ich opisu bazującymi na standardzie SysML.

Rozmaitość zawodów robotów, organizowanych na całym świecie, wskazuje na to, że bez wahania możemy juz mówic o robotyce sportowej - nie tylko jako dziedzinie rozrywki, ale także badań. W ostatnich latach wykreowano kilka popularnych konkurencji, dla których sformułowano wymagania dotyczace konstrukcji i oprogramowania robotów. Standaryzacja wymagań obiektywizuje wynik rywalizacji, podobnie jak ma to miejsce chociazby w wyscigach Formuły 1. Jednym z problemów standaryzacji było ujednolicenie srodowiska, w których konkurują roboty sportowe śledzące linię na czas. W niniejszym artykule opisujemy prace, które doprowadziły do opracowania, wytworzenia i weryfikacji modularnego środowiska do rywalizacji tego typu robotów (ang. Line Follower).
