In the existing robot-rat interaction, robots usually exert influence as stimuli to observe the response of target rats. However, the above single-stimulation model from robot to rat lacks a two-way communication. Therefore, we proposed a method to learn the rat-like behavioral interaction. First, we constructed two behavior patterns in the interaction process between the two rats: the individual pattern and the interaction pattern. We divided the roles of the two rats into active stimulator and passive receiver. The stimulator executes the individual pattern, and the receiver switches between the two patterns. Which pattern the receiver executes depends on the probability of interaction. Secondly, we proposed a hypothesis concerning the behavioral interaction between two rats and controlled the interaction process between two robots. information entropy was used to measure the similarity between two robots and two rats. The results proved that the probability of interaction between rats depends on the distance of centroid and average relative velocity, and we obtained the optimal solution to express the relationship between them. In the future, the improvement of robots' interaction ability with rats will highly benefit from this study. © 2022 IEEE.

To enhance the prediction accuracy of the remaining useful life (RUL) of lithium-ion batteries, this study proposes a novel RUL prediction model, termed FDNet, which integrates Discrete Fourier Series (DFS) and Densely Connected Convolutional Networks (DenseNet). In contrast to traditional methods that rely on one-dimensional (1D) numerical representations of time-series data, this model utilizes a two-dimensional (2D) visual representation for direct RUL prediction. First, the DFS is employed to convert 1D time-series signals into a 2D time-frequency domain, enabling the extraction of high-dimensional features from the original data. Then, these 2D images are subsequently input into DenseNet, which learns the mapping between the image features and the RUL targets. Finally, the proposed model is validated using the NASA lithium-ion battery aging dataset, and the results indicate that FDNet achieves superior prediction accuracy and exhibits notable robustness. © 2024 IEEE.

With the increase in maritime activities, traditional communication methods can no longer meet the needs of today’s maritime work, and the use of unmanned aerial vehicle(UAV) relay communications in marine scenarios has attracted more and more attention. In this paper, A long-distance three-node two-hop UAV relay system for maritime users is investigated. The UAV aerial relay node first transmits an energy-carrying radio frequency (RF) signal to the maritime user node, which then harvests energy and sends data information back to the UAV aerial relay node, which in turn forwards it to the land node. Considering the peculiarities of maritime communication channels, a novel land-air-maritime communication channel model is proposed. Utilizing Zero-Forcing/Zero-Transmission (ZFR/ZFT) technology, a precoding matrix for the aerial relay node is designed, followed by simulation and emulation, the performance of the channel is tested in the case of different transmission power of relay nodes or different number of antennas of relay nodes. © ICST institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2025.

For a lecture in a classroom, it is empirically known that the students are more engaged in the lecture and exhibit a better understanding of the content of that lecture. We hypothesize that the effect is due to the quality of sound produced by the teacher and received by the students. Specifically, the voice spoken by a teacher facing toward students will have a better acoustic characteristic than the voice spoken opposite to the students, which contributes to the comprehension of the words spoken by the teachers. To this end, we first conducted experiments to examine the difference in sounds reaching directly to the students and after bouncing on a wall in some typical classroom environments. Second, we conducted experiments to examine the difference in the number of remembered words from spoken ones. The experiments compared the cases between the word-speaking teacher's orientations either to the students or opposite to the students. The results from these experiments showed that the sound heard from a teacher facing toward students in a classroom has a higher acoustic pressure level at around 800-900Hz, which is close to the first formant. Also, the memorizing test showed that the teacher's voice contributes to improving the number of remembered words from the words spoken by the teacher. Our results show the importance of looking at students during lectures in a classroom. Also, it suggests an automatic tool to count the frequency of a teacher to look at students, which will help the teacher to self-evaluate his/her lecture. © 2024 IEEE.

In many practical applications like rescues, the morphing quadrotors perform better than conventional quadrotors in complex and variable environments, such as traveling through narrow gaps. However, their dynamic properties are more complicated. In this paper, a new morphing quadrotor with foldable arms is presented. Then, the dynamic model of the morphing quadrotor is established. Moreover, the linear active disturbance rejection control (LADRC) method is used to achieve stable flight during morphing, and its performance is compared with the PID method with the simulations. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

intelligent robots are employed in a variety of sectors due to their capability to carry out tasks autonomously. As a response to the growing importance of intelligent robots, a new master’s program in intelligent robotics was introduced by Kazan Federal University, Russia in 2017. It was created by analyzing the curricula of leading robotics universities worldwide. The main objective of this master’s program is to provide in-depth knowledge to students regarding intelligent robots’ development and applications. Classes of the program were conducted by combining theoretical lectures with applications of robotics software and hardware tools. Computer-aided design (CAD) software and Robotic Operating System (ROS) libraries were practiced by students in courses. We present an approach for designing and modeling projects within the robotics and Mechatronics course for first-year students using SOLIDWORKS and ROS. Educational methodologies adopted by a student are presented in this article as a case study of an elevator-operating robot.

In this work, we conduct performance analysis of a Fault Tolerant Control (FTC) scheme for hexacopter actuator failure through hardware-based fault detection and dynamic control reallocation. Hall effect sensors are used to monitor motor speeds and compared with the reference signals generated by the flight controller (FC) for anomaly detection. Experimental flight tests demonstrate the efficacy of the proposed FTC in detecting the faults and subsequent flight stabilization. The performance of the proposed FTC (quantified in terms of tracking error in attitude dynamics) is compared with the ideal fault detection (no delay between fault occurrence and control reallocation) case.

Observability-based Placement of Inertial Sensors on Robotic Manipulators for Kinematic State Estimation

引用

IFAC-PapersOnLine 2023年第2期56卷 5293-5299页

作者： Michael Fennel Lukas Driller Antonio Zea Uwe D. Hanebeck Intelligent Sensor-Actuator-Systems Laboratory (ISAS) Institute for Anthropomatics and Robotics (IAR) Karlsruhe Institute of Technology (KIT) Germany

In recent years, the demand for accurate and delay-free kinematic state estimates, especially regarding acceleration, led to the adoption of inertial sensors placed along the kinematic chain of robotic manipulators. With state-of-the-art signal processing algorithms, arbitrary setups of accelerometers and gyroscopes can be deployed, raising the question of where and how many sensors should be placed for an optimal estimation quality. This paper presents a novel observability-based approach to answer this question independent of a specific estimator implementation. For this purpose, methods for calculating the required sensor measurement ranges and predicting the estimation quality regarding velocity and acceleration are introduced and discussed. The resulting procedure is validated successfully by comparing predicted and actual estimation quality for two example manipulators, indicating that it can provide meaningful aid to a design engineer.
