In recent years, with the increasing number of stroke patients, master-slave telerehabilitation has become one of the research hotspots in the field of rehabilitation. However, when estimating the angle of the main end, the angle estimation model is difficult to be widely applicable due to the different muscle tension of the physiotherapist itself. During remote rehabilitation training, it is difficult for physical therapists to obtain the damage of the affected limb, so it is difficult to arrange appropriate training intensity and training volume, which affects the effect of remote rehabilitation to a certain extent. To address these issues, this paper proposes a novel master-slave rehabilitation system. The therapist obtains his own muscle tension level a priori through FSR402, and jointly estimates the movement angle through the (Surface Electromyography) sEMG signal collected by MYO, so as to control the slave end. While following the rehabilitation training, the patient at the slave end reflects real-time muscle force of the affected limb and the true feeling of the movement to the master end through the muscle tension measurement arm cuff and the relevant buttons on the PC end. The overall system realizes data transmission through (User Datagram Protocol) UDP, so as to realize more secure and personalized master-slave control. The experiment proves that the new master-slave rehabilitation system is real and feasible. © 2023 IEEE.

WSNs are applied in many disciplines where certain conditions require the ability to adapt to network sink mobility and changes in the dynamics of the area coverage. To meet these needs, it is necessary to develop integrated systems where the ''terrestrial' systems and the Unmanned Aerial Vehicles (UAVs)' collect data from sensors efficiently. Planning of UAV trajectories is another challenging issue if many WSN nodes are randomly deployed. This challenge has a big impact on the overall effectiveness of the system. This paper presents a novel approach for reducing the traveled distance of unscrewed aerial vehicles (UAVs) to improve the data collection efficiency in WSNs with poor node density. Yet the method that has been developed is aimed at increasing 'the efficiency and efficacy of data collection... with the assistance of Unmanned Aerial Vehicles (UAVs)' which means this work reveals practical application solutions. © 2024 IEEE.

We consider the problem of signal detection in a massive multiple-input multiple-output (MIMO) system with one-bit analog-to-digital converters (ADCs), where both transmitter (Tx) and receiver (Rx) are equipped with multiple antennas. Traditional maximum likelihood (ML) algorithm exhaustively searches for the optimal solution, the computational complexity of which, however, grows as the number of transmit antennas increases. In order to reduce the computational complexity, we propose a fast local search algorithm that can rapidly search for the solution with the maximum likelihood. The proposed scheme involves two steps. The first step finds an initial search point via a simple zero forcing (ZF) approach, while the second step searches for the final solution around the initial point in a local area. A curve fitting method is also adopted to further reduce the computational complexity of calculating the cumulative distribution function (CDF) of Gaussian distribution. The proposed method is fast and easy to be realized in practical systems. Simulation results show that the proposed algorithm almost achieves near ML performance for BPSK and QPSK modulation with a computational complexity reduction of more than an order of magnitude compared with existing methods. © 2023 IEEE.

This study provides an adaptive filtered prescribed-time position control scheme for motor driving servo systems. A desired error trajectory is constructed by employing a smoothly decreasing continuous function, such that the prescribed-time position tracking control of the motor driving servo system can be equivalently transformed into the error tracking control design. Then, a prescribed-time controller is developed to drive the position tracking error to track the desired error trajectory, such that the error convergence can be achieved at the prescribed settling time. Besides, a novel adaptive filter is presented to avoid differentiating virtual control variables in recursive procedures and ensure the filter error convergence into a small bound near the origin within the preset finite time. Some experiments on a practical motor driving servo system are performed to verify the effectiveness of the proposed method. © 1986-2012 IEEE.

Contact-free manipulation technology represents a novel approach that offers a fresh possibility for human-machine interaction, aiming to meet the evolving demands of this interface. In this paper, we introduce a contact-free planar display control technique based on imaging. In our research, we employ cameras as sensors and integrate infrared lasers with image processing techniques to detect and localize input signals. By establishing a coordinate mapping relationship between the operational plane and the display plane, we achieved contact-free control over the planar display. Our paper introduces two methods for establishing this coordinate mapping. The first involves constructing mapping functions between the rectified and transformed camera imagery and the display plane, thereby creating a point-to-point correspondence. The second method entails dividing both the camera imagery and the display plane into segments, establishing a one-to-one relationship between regions. We analyze the strengths and limitations of these two approaches. While the former boasts higher theoretical precision, it is more susceptible to equipment factors and exhibits slower response speeds. Conversely, the latter, despite its lower theoretical precision, offers faster response times. Through the setup of an experimental platform, we demonstrate the feasibility of our proposed. © 2024 SPIE.

The emergence of vascular interventional surgery robot (VISR) has brought good news to patients. However, the current research on the master manipulator is still in its infancy. Nowadays, the shortcomings of the developed master manipulator include poor portability, lack of tactile feedback devices, not in line with surgeon's operating habits and so on. In order to solve the above problems, a novel master manipulator is proposed in this paper. In order to realize the linear displacement measurement of the operating handle, a linear displacement measurement (LDM) unit based on rollers was proposed. By using the brushed DC motor and the bevel gears, the angular displacement measurement (ADM) unit and the circumferential force feedback (CFF) unit were designed. The decoupling of the operating rod and the rotating rod facilitated the portability of the proposed manipulator. Evaluation experimental results showed that the maximum linear error of the master manipulator was 0.296mm and the maximum angular displacement error was 7.66 degrees, which is acceptable. Moreover, the mathematical relationship between the circumferential force generated by the CFF and the input current was also obtained. To sum up, compared with other master manipulators, the proposed master manipulator is shown to be better and more promising. © 2023 IEEE.

In recent years, with the rapid economic growth in my country, environmental problems have become more severe, among which the problem of heavy metal pollution in soil is particularly prominent. Soil is the material basis for human survival. In order to ensure human health and achieve sustainable development, the control and treatment of soil heavy metal pollution is imminent. Based on the sparrow search algorithm, this paper establishes a soil quantitative detection model, and uses the algorithm’s population optimization performance to detect soil heavy metal content. And a detection model based on the improved algorithm was proposed, and the detection accuracy of the models under the two algorithms and the relative error of each heavy metal element were compared, and the effectiveness of the improved sparrow search algorithm in soil quantitative analysis was verified. © 2023, ICST Institute for Computer sciences, Social Informatics and Telecommunications engineering.
