Oculomotor activity is an important component of human mental processes, and decoding this activity can be applied in many applied fields. This paper analyzed the physiological and behavioral characteristics of a person during a prolonged solution of a cognitive task based on the Sternberg paradigm. A number of trends in changes in both physiological and behavioral characteristics over the course of the experiment were revealed. For example, an increase in subjective fatigue over the course of the experiment. In addition, correlation analysis were performed. In particular, a correlation was found between subjective fatigue and the amplitude of pupil dilation during letter set demonstrations. © 2022 IEEE.

Static Object grasping is a challenging task that has been studied for decades. The difficulty of the task comes back to the reason that a grasping attempt can have many solutions or due to the uncertainty about the targeted object's features and characteristics. This makes the fact about dynamic object grasping with un-modeled dynamics even more challenging. In this paper, an approach for dynamic object grasping is presented. The approach considers human-robot handover operation where the robot should be able to track human's holding-object hand and plan a successful grasp of the object in hand. The system was implemented with the help of Mixed-Reality using HoloLens glasses for human's hand tracking. A serial manipulator was used to execute the operation mounted with end-effector-mounted camera to perform computer vision operations for grasp planning and correction. The main task is robot at random configuration can be able to find hand-holding object and plan grasp on object in hand. The implemented system shows success and was able to perform most of the grasping tasks successfully. © 2021 IEEE.

In this work, we conducted the analysis of the functional magnetic resonance imaging data in healthy subjects and patients with major depressive disorder that were obtained during experimental research when subjects were resting. The signals that have undergone preprocessing and filtration were used to find the functional connectivity between the brain regions. Results demonstrate significant changes between functional connections based on the mutual information measure. We obtained five significantly changed connections, four of which increased more in cotrol group over patients. © 2023 IEEE.

Gesture recognition is one of the natural ways of human-computer interaction (HCI) that will positively affect their use. This paper presents an approach for real-time static gestures recognition based on the skeleton of a hand using a MediaPipe framework and Support Vector Machine(SVM) classification. The approach demonstrated high accuracy of recognition gestures 98.74% on a dataset of sign-digit-gestures as well as runtime 71 fps. Moreover, the approach is required only one camera sensor for recognition. The proposed approach can be extended for dynamic gesture recognition and used to control robots and computer devices. © 2021 IEEE.

In the present study, we investigated the effect of single-pulse TMS on sensorimotor integration (SI). Real and sham TMS was delivered while a subject performed a cognitive task to 6 areas of the cortex responsible for the motor component of SI, 200 ms or 800 ms after the presentation of visual stimuli. Here we show that the time of single-pulse TMS delivery affects the subject’s reaction time (RT). RT was significantly slower (p ©2024 IEEE.

This paper deals with the challenges involved on roof building gutter maintenance robot design, from the problem statement of secure teleoperated semiautonomous navigation on confined gutter spaces, and the best selection of right mechatronics brush to remove the waste on gutter surface;Two concept design have been tested: Passive Brush with Parallel locomotion (PBP), and Active Brush Axial (ABA). The results on our development are shown, as following: secure robot lifting regulation, simulation environment, HMI to teleoperate, mechatronics design. Finally, some tests on simulations and current prototypes are shown, to validate our proposal, and the conclusion that the ABA design allows to remove until 85% gutter waste, instead of PBP design;furthermore, the ABA allows independent brush rotation velocity, instead of PBP design. © 2023 IEEE.

On Smooth Planar Curvilinear Motion of Cable-Driven Parallel Robot End-effector*

The paper deals with the problem of smooth motion of the end-effector of an overactuated cable-driven parallel robot. There is observed a way to give planar curvilinear trajectory via Fourie series. The idea of this work is to use special sigmoid function as an argument of function composition to achieve smoothness at the beginning of motion of the end-effector of a cable-driven parallel robot. The developed method makes it possible to reduce the positioning errors of the end-effector when moving along complex trajectories.

There is a burgeoning interest in the field of Reinforcement Learning (RL) across various domains, including robotics. Traditional control approaches for robotic systems, such as semi-definite programming (SDP) or mixed integer programming (MIP), typically rely on the assumption of a known and deterministic model of the environment. In contrast, this study aims to introduce a novel RL method for planning the reward function specifically tailored for underactuated robotic systems with parameter uncertainty. We propose a method with a single RL agent to address the challenge of swing up and balance of a Pendubot system with uncertain parameters. The ultimate objective is to enhance the system’s ability to adapt and perform reliably in the face of varying uncertainties.

We analyzed fMRI data from healthy control subjects (94 subjects) and patients with major depressive episode (70 patients). The preprocessed activity signals extracted with statistical parametric mapping from fMRI were divided into parcellations according to the anatomical labeling atlas. Our findings indicate that patients with major depressive disorder exhibit network organization that is both less locally specialized and less globally integrated. Specifically, our research reveals differences in network segregation rather than integration in patients. The discrepancies between our results and previous studies may be attributed to differences in methodology, depression diversity, sample sizes, and co-occurring factors such as stress and anxiety.

Healthy aging affects structural and neurochemical properties of the human brain neural network. It also changes the brain functioning via the transformation of neural interactions both within and between functionally distinct brain areas. The age-related degradation of the brain functioning is evident on the behavioral level in terms of the decline in reaction time, low ability to execute and control complex motor actions, weak flexibility in learning new skills. In this paper we apply functional connectivity analysis to reveal the age-related changes in the integrative brain dynamic during the motor initiation before the dominant hand movements accompanied. Analyzing the whole-scalp electroencephalography (EEG) signals on the sensor level, we find higher theta-band coupling in the ipsilateral hemisphere. © COPYRIGHT SPIE.
