This paper presents a gesture-controlled six-degree-of-freedom (6-DoF) manipulator with a custom-designed gripper for practical pick-and-place tasks, a new approach to human robot interaction. The robotic arm can be controlled smoothly by integrating cutting-edge sensing technologies and real-time processing algorithms that accurately understand human motions. This allows the robot to be controlled remotely, which is safe for the operator. This manipulator's specially-made gripper is optimised for pick-and-place operations and can accommodate various object sizes and shapes. Incorporating intelligent sensors and machine learning algorithms augments the manipulator's capacity to comprehend and adjust to its surroundings, guaranteeing accurate and dependable object manipulation. The gesture control interface uses modern computer vision and machine learning techniques to communicate naturally between the user and the robotic system. The suggested approach encourages accuracy, speed, and usability results through a thorough study, highlighting its potential to improve human-robot collaboration in industrial settings. The present study advances the field of robotic manipulation by presenting an intuitive and effective control mechanism and tackling issues of precision and flexibility in pick-and-place tasks. The system that has been built has the potential to transform the relationship between humans and robots, increasing accessibility and versatility in a wide range of applications. © 2024 IEEE.

In this study, we present an advanced approach to global path planning for mobile robots, grounded in the refinement of the ant colony algorithm. The conventional implementation of this algorithm often encounters the "stalemate" issue and struggles to attain the globally optimal solution. By strategically modifying the transition probabilities of ants within the traditional framework, we mitigate the frequency of "stalemate" occurrences. Furthermore, we incorporate the roulette wheel selection methodology from genetic algorithms, thereby circumventing the tendency towards local optimization inherent in the ant colony algorithm. Through rigorous simulation experiments, we have optimized and identified the most suitable parameter combination for the refined ant colony algorithm, enhancing its applicability and performance. Finally, it proves that the improved ant colony algorithm can greatly improve the path planning efficiency through Matlab2016b. © 2024 Copyright held by the owner/author(s).

Agriculture is one of the most important aspects across the globe which is also a primary task for any country to lead their economic growth and to be a healthy country. The objective of agriculture is to produce various food materials, vegetables and fruits as an outcome of the process. But to provide the outcome from agriculture is not as simple as it looks, Farmers face many issues while making the outcome and they need to work separately to overcome this problem. One of the issues faced by the farmer is the weed management. Weed Management is that the method of dominant that the expansion and removal of the weeds in timely manner. The weeds present in the fields have a major impact on the farmers in terms of their reduction in yield and loss in the capital income. In all recent surveys, it is stated that Weeds present in the field causes almost 60 to 75 percentage loss in agriculture. In order to solve this problem and to give a tentative visioned solution, this project focuses on the development of a mobile robot which can identify the weeds in the field while traversing the field and also capable of differentiating the weeds with crops and other small plants and after the identification, weeds are removed by the weed remover. Apart from removing the weeds this project can also give the small summary of the traversed agricultural land. © 2024 IEEE.

There are several methods successfully used for Process Improvement. In EQualPI (a framework to Evaluate the Quality of Implementation of Process Improvements) our main concerns are the performance in terms of efficiency and effectiveness of the outcomes of a process, this being more relevant than only considering compliance. Additionally, we believe that a Process Improvement method must be repeatable, reliable and unbiased. Given that the scientific Method is used to create new knowledge, applying such method to Process Improvement can greatly contribute to more rigorous and less prone to bias results. In this paper we present our definition of the scientific Method applied to Process Improvement, which we have based on and validated through a quasi-experiment with two groups of graduate students and undergraduates. The output of our process improvement was later adopted by an organisation. Our method is tailorable and with our quasi-experiment we showed that the scientific Method in Process Improvement can be applied to smaller and lower maturity organisations.

In order to improve the state monitoring capability of power devices and simultaneously obtain temperature and dynamic and static stress responses, a state monitoring system was designed based on optical fiber sensor network. The chirped grating modulation technique was used on the Fiber Bragg Grating sensor package to make the temperature and strain response of the test position different, so that the simultaneous solution of the two parameters was realized by the decoupling algorithm. On the basis of constructing a two-parameter decoupling model, the trends of temperature and strain with respect to wavelength were simulated and analyzed. In the experiment, the state of the power device was tested and analyzed from three aspects. In the temperature calibration experiment, the temperature responds linearity reached 0.9986, and the deviation of the comparison test result with the FOT2300 temperature detector was better than 1.3%. In the static strain response experiment, the system sensitivity in the range of 0.1kN-1kN was 0.0036nm/N, and the system sensitivity in the range of 1kN-5kN was 0.0018nm/N. In the dynamic response experiment, the impact of heavy objects at different heights had obvious peak differences. The wavelength offset was inversely proportional to the time half-width, and the spectral line shape had obvious characteristics. It can be seen that the system has good distinguishability when obtaining the state information of power device temperature and static and dynamic stress. © 2023, Politechnica University of Bucharest.

In this paper, the data-based fault detection and diagnosis (FDD) of the pneumatic robot AirArm by artificial neural networks is demonstrated. Faults, in this case, correspond to pressure drops in the pressure cylinders. Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) are used for this purpose. In addition to a general concept of fault detection and diagnosis of complex technical MIMO systems, the effectiveness of the approach is presented by means of a repetitive task of the robot. Subsequently, the transferability of the approach to a partially unknown trajectory is examined. Finally, the method is proven during operation. © 2022 IEEE.

Condition Monitoring (CM) is an important approach to extending the life of complex equipment by forecasting the outcome of an event before catastrophic failure occurs. Recent advancements in digital twins (DT) offer additional benefits to machine condition monitoring. In this study, a framework based on DT for real-time condition monitoring of industrial machines is proposed. The multi-layer DT framework consists of a physical entity (PE), virtual equipment (VE), edge device, fidelity service and digital twin services. The virtual equipment is a replica of the physical entity or the monitored machine. It also contains a cloud platform to store data online and an application to interface with the cloud enabling users to check the data remotely. The fidelity service ensures conformity between the PE and the VE. The digital service provides optimal operation and maintenance schedules based on the data from both physical and virtual spaces. The integration of the edge layer enables real-time handling of high-frequency machine data for effective health monitoring. The validity of the proposed framework is demonstrated with a case study based on monitoring a critical component of an industrial drivetrain test rig. The features of the framework allow end-users to visualize the component's real-time health status remotely. © 2023 IEEE.

Accurate ranging between underwater communication nodes and reliable underwater acoustic communication technology are indispensable for large-scale oceanic studies. Effectively combining ranging and communication methods and applying them in underwater acoustic modems is an attractive strategy worth studying. To meet these requirements, we propose an asynchronous time delay estimation (ATDE) for accurate ranging. The ATDE exploits the Linear Frequency Modulated (LFM) waveform, which is originally used for synchronization of communication signals, to enable the modem to function as an Integrated Communication and Ranging System (ICRS). An adaptive retransmission algorithm is put forward to improve the reliability of communication based on the range and signal to noise ratio (SNR) obtained from ATDE. Extensive simulations are conducted to verify the feasibility of the proposed ranging method and the superiority of the retransmission algorithm in terms of throughput and false packet rate when compared with the conventional method. A preliminary field experiment is conducted near Zhairuoshan Island in Zhoushan Archipelagoes, Zhejiang Province, China, using self-developed modems. Both the simulation and experimental results demonstrate that the proposed scheme has robust ranging ability and offers more reliable data transmission in underwater acoustic communication. © 2023 IEEE.

Addressing the issue where farmers struggle to identify Lycium barbarum aphid infestations during the growth process, leading to missed optimal control opportunities and subsequent economic losses, this paper proposes a method for identifying Lycium barbarum aphid infestations based on an improved YOLOv11 algorithm. Firstly, the Shape-IoU bounding box regression loss calculation method is employed to calculate loss by focusing on the shape and scale of the bounding box itself, resulting in more accurate bounding box regression. Secondly, the Lightweight Adaptive Extraction (LAE) module is utilized to optimize the target detection network model of YOLOv11, reducing parameters and computational costs. Experimental results demonstrate that, compared with the unimproved YOLOv11 algorithm, the improved YOLOv11 algorithm achieves a 2.7% increase in mean Average Precision (mAP) and a 9% increase in F1 score, validating the feasibility of this method. © 2024 IEEE.
