    Opis:
    This paper presents a concept of humanoid robot motion generation using the dedicated simplified dynamic model of the robot (Extended Cart-Table model). Humanoid robot gait with equal steps length is considered. Motion pattern is obtained here with use of Preview Control method. Motion trajectories are first obtained in simulations (off-line) and then they are verified on a test-bed. Tests performed using the real robot confirmed the correctness of the method. Robot completed a set of steps without losing its balance.

    Opis:
    Most ship collisions and grounding accidents are due to errors made by watchkeeping personnel (WP) on the bridge. International Maritime Organization (IMO) adopts the resolution on the Bridge Navigation Watch Alarm System (BNWAS) detecting operator disability to avert these accidents. The defined system in the resolution is very basic and vulnerable to abuse. There is a need for a more advanced system of monitoring the behaviour of WP to mitigate watchkeeping errors. In this research, a Bridge Navigation Watch Monitoring System (BNWMS) is suggested to achieve this task. Architecture is proposed to train a model for BNWMS. The literature reveals that vision-based sensors can produce relevant input data required for model training. 2D body poses belonging to the same person are estimated from multiple camera views by using a deep learning-based pose estimation algorithm. Estimated 2D poses are projected into 3D space with a maximum 8 mm error by utilising multiple view computer vision techniques. Finally, the obtained 3D poses are plotted on a bird’s-eye view bridge plan to calculate a heatmap of body motions capturing temporal, as well as spatial, information. The results show that motion heatmaps present significant information about the behaviour of WP within a defined time interval. This automated motion heatmap generation is a novel approach that provides input data for the suggested BNWMS.

    Opis:
    Human motion is required in many simulation models. However, generating such a motion is quite complex and in industrial simulation cases represents an overhead that often cannot be accepted. There are several common file formats that are used nowadays for saving motion data that can be used in gaming engines or 3D editing software. Using such motion sets still requires considerable effort in creating logic for motion playing, blending, and associated object manipulation in the scene. Additionally, every action needs to be described with the motion designed for the target scene environment. This is where the Motion Model Units (MMU) concept was created. Motion Model Units represent a new way of transferring human motion data together with logic and scene manipulation capabilities between motion vendors and simulation platforms. The MMU is a compact software bundle packed in a standardized way, provides machine-readable capabilities and interface description that makes it interchangeable, and is adaptable to the scene. Moreover, it is designed to represent common actions in a task-oriented way, which allows simplifying the scenario creation to a definition of tasks and their timing. The underlying Motion Model Interface (MMI) has become an open standard and is currently usable in MOSIM framework, which provides the implementation of the standard for the Unity gaming engine and works on implementation for the Unreal Engine are under way. This paper presents two implementation examples for the MMU using direct C# programming, and using C# for Unity and MOSIM MMU generator as a helping tool. The key points required to build a working MMU are presented accompanied by an open-source code that is available for download and experimenting.

    Opis:
    W pracy podano nowe pojęcia, dotychczas nie stosowane w biomechanice chodu człowieka, zwane przez autorów pracy zasobami ruchu. Zasoby ruchu kończyn dolnych człowieka pozwalają - nie tylko na podstawie pomiarów kinematycznych dokonanych w czasie rzeczywistym - monitorować, kontrolować i oceniać w sposób dynamiczny(!) stan i zmianę zasobu ruchu kończyn dolnych człowieka w warunkach klinicznych jak i polowych (na stadionach po różnorodnej powierzchni np. błocie, śniegu, trawie, schodach itp.). W pracy zaproponowano innowacyjną aparaturę nowej generacji, do badania chodu człowieka zwaną zasobometrem. Pracuje on w trybie on-line i pozwala oceniać chód człowieka - równocześnie dla obu kończyn dolnych. Cena rynkowa zasobometru jest kilkanaście razy mniejsza aniżeli systemów rejestracji ruchu jak np. włoski system optoelektroniczny ELITE-3D - produkowany przez włoską firmę BTS z Mediolanu.
    On this paper a new notion, which has never been applied in investigation of human gait, is described. This is MOTION RESOURCES COEFFICENT named in polish language ZASOBY RUCHU. A new Motion Resources Apparatus (the MRA) for research, investigation and assessing human gait - in natural condition - has been presented. The MRA is an apparatus of a new generation which allows to reduce significantly cost of investigation multistep of human gait - in natural condition.

    Opis:
    This paper presents the application of the reinforcement learning algorithms to the task of autonomous determination of the ship trajectory during thein-harbour and harbour approaching manoeuvres. Authors used Markov decision processes formalism to build up the background of algorithm presentation. Two versions of RL algorithms were tested in the simulations: discrete (Q-learning) and continuous form (Least-Squares Policy Iteration). The results show that in both cases ship trajectory can be found. However discrete Q-learning algorithm suffered from many limitations (mainly curse of dimensionality) and practically is not applicable to the examined task. On the other hand, LSPI gave promising results. To be fully operational, proposed solution should be extended by taking into account ship heading and velocity and coupling with advanced multi-variable controller.

    Opis:
    The present paper proposes a simple model for the calculation of a time series to control the horizontal motion of the piston of a wavemaker. It is assumed that the initial conditions correspond to water at rest. It is assumed that parameters of kinematics of the fluid (displacement, velocity and acceleration fields) at the initial time are equal to zero. In the first interval the amplitudes grow to an asymptote that corresponds to a regular monochromatic wave. In the second interval the waves decay. Calculated time series were fed in to the control system of our wavemaker and the measured horizontal displacements of the piston compared. The control series was supplemented by terms corresponding to the Stokes type solution by addition of terms with multiples of the basic frequency.

    Opis:
    The present study deals with fluid flow, heat transfer and entropy generation in a two-dimensional channel filled with Cu–water nanoliquid and containing a hot block. The nanoliquid flow is driven along the channel by a constant velocity and a cold temperature at the inlet, and the partially heated horizontal walls. The aim of this work is to study the influence of the most important parameters such as nanoparticle volume fraction (0%≤ϕ≤4%), nanoparticle diameter (5 nm≤dp≤55 nm), Reynolds number (50≤Re≤200), Hartmann number (0≤Ha≤90), magnetic field inclination angle (0≤γ≤π) and Brownian motion on the hydrodynamic and thermal characteristics and entropy generation. We used the lattice Boltzmann method (LBM: SRT-BGK model) to solve the continuity, momentum and energy equations. The obtained results show that the maximum value of the average Nusselt number is found for case (3) when the hot block is placed between the two hot walls. The minimum value is calculated for case (2) when the hot block is placed between the two insulated walls. The increase in Reynolds and Hartmann numbers enhances the heat transfer and the total entropy generation. In addition, the nanoparticle diameter increase reduces the heat transfer and the irreversibility, the impact of the magnetic field inclination angle on the heat transfer and the total entropy generation is investigated, and the Brownian motion enhances the heat transfer and the total entropy generation.

    W pracy przedstawiono algorytm generowania trajektorii dla zadania transportowego realizowanego przez dwa roboty. Algorytm wyznacza wymagane pozycje i orientacje chwytaków robotów w trakcie skoordynowanych ruchów. W celu weryfikacji uzyskanych danych wykorzystano system Delmia. Zaproponowano procedurę przeniesienia danych z systemu LabVIEW do systemu Delmia oraz budowy, na ich podstawie, modelu stanowiska oraz definiowania zadań dla robotów. Etapy pracochłonne procedury zostały zautomatyzowane przy pomocy makr, pozostałe są realizowane manualnie. Zbudowany wirtualny model stanowiska wykorzystano do weryfikacji zdefiniowanych zadań dla robotów. Opracowany tok postępowania zilustrowano przykładem.

By using a 5 link belt mechanism with 2 DOF can be adapted for generating similar Jansen mechanism path curve, where the step height of this path can be increased. For this purpose a mathematical model is conceived in order to analyse and determine the parameters for driving and control of the operation of the novel walking leg solution.

    Opis:
    An investigation has been carried out for the MHD 3-dimensional flow of nanofluid over a shrinking sweet saturating a porous media in the presence of thermal radiation and heat generation. Convective boundary conditions for the flow phenomena are used in the present analysis. The governing equations are reduced to ODEs employing suitable similarity transformations. The solutions of formulated differential equations have been attained mathematically by fourth order R-K technique along with the shooting method. The impact of the governing constraints on momentum, heat, and local Nusselt number, are explored. It is noticed that the momentum and heat decrease with raise in the porosity variable, temperature reduces with an enhance in the thermal radiation variable, and temperature enhances with an enhance in the heat source/sink parameter.
