This study aimed to find out the prototype of an EVOCE robot that gave impact of students’ English vocabularies enhancement. In this study, the authors used two types of research design, namely, prototyping method and experiment research design. The mixed method is applied in this research qualitatively and quantitatively. Both vocabulary tests and observational methods of prototyping data collection were employed. The robot prototype used in the class as a tool to examine how was the effect of this media helped young learners in acquiring basic English vocabulary. The prototype has been through the test and the result showed that it suited with the needs for young learners. Nonprobability sampling was the technique used. A total of 40 students from two classes made up the research sample. The vocabulary score achievement pre and post test using EVOCE robot was compared with data analysis and t-test. The findings of value of t-stat > t-table at the significant level of 5% (1,679 > 1,328) meaning that the robot helped students become better acquisition in getting new vocabulary and influenced their level of vocabulary score. As the result, this research therefore has consequences for the teacher’s understanding that the usage of robots can both increase students’ vocabulary and also have an impact on their level of English proficiency.

Visual place recognition (VPR) is considered among the most challenging problems due to the extreme variations in appearance and viewpoint. Essentially, appearance-based VPR can be considered as an image retrieval task, thus the key is to accurately and efficiently describe the images. Recently, global descriptor methods have attracted substantial attention from the VPR community, which has contributed to numerous important outcomes. Despite the growing number of global descriptors presented, little attention has been paid to the comparison and evaluation of these methods and so it remains difficult for researchers to disentangle the factors that led to better performance. This study provided comprehensive insight into global descriptors from a practical application perspective. We present a systematic evaluation that integrates 15 commonly used global descriptors, 6 benchmark datasets, and 5 evaluation metrics, and subsequently extended this evaluation to discuss the key factors impacting the matching performance and computational efficiency. We also report practical suggestions for constructing promising CNN descriptors, based on the experimental conclusions. Our analysis reveals both advantages and limitations of three different types of global descriptors, including handcrafted features-based ones, off-the-shelf CNN-based ones, and customized CNN-based ones. Finally, we evaluate the practicality of reported global descriptors to mediate the trade-offs between matching performance and computational efficiency.

All along, safety accidents in the field of bridge construction have continued to arise, costing society's development financial and material resources and taking away people’s personal safety, turning into an urgent need for safety managers in the field to solve the subject research. Researchers look forward to continued innovative exploration to find new ways of working safely and using them in the construction industry. On this basis, BIM virtual scenes are introduced to create a universal scene specification dataset in the field of bridge construction and a dataset of unsafe potential hazard characteristics in the field of bridge construction. Nanobots are artificial intelligence systems built to simulate biological nanomachine constructions in life activities and important biological events in life processes. In this paper, BIM virtual scenarios incorporating intelligent nanomaterial robot mapping technology are migrated to bridge engineering safety management. According to the collected construction scene images and BIM (building information model) virtual scenes, build the construction scene dataset, use intelligent robots to obtain construction scenes, and load them into the trained construction on-the-spot neural network modeling to complete the bridge construction scene identification safety discrimination to select more comprehensive and more stringent management solutions as safety management personnel management methods on-the-spot.

In the Internet of Things (IoT) era, the combination of mobile robots and IoT technology has realized the complementary advantages of the IoT and robots, which has brought new challenges and opportunities for the development and application of the IoT and mobile robots. In this study, a mobile robot positioning system based on the wireless positioning technology of the IoT is first designed, and an adaptive federated filtering algorithm based on the confidence of the sensor measurement data is given, and the data fusion processing is carried out for the positioning system to achieve the accurate positioning of the mobile robot. Then, we embed the intelligent control system of the ring lamp and propose an adaptive fuzzy PI double closed loop equalization control strategy, which can automatically identify the number of interlaced parallel and ensure its equalization effect. The experimental results show that the equalization strategy designed in this study has a good equalization effect in the loop interleaving parallel topology, strong adaptive parameter adjustment ability, good robustness, and anti-interference.

With the in-depth study of architectural planning in China, more and more designers and developers are aware of the superiority of the use of technological robots to improve the speed and quality of construction, weakening past experience and based on real-world research through modern technology. However, the application of this method in the predesign work is not mature. To be specific, designers may lack expertise due to the overly detailed division of labor. In addition, the developer’s blind pursuit of profitability leads to inaccurate market positioning and forecasting. At the same time, the lack of effective communication between designers and developers, architects and owners makes the predesign work ineffective and does not provide reasonable and accurate guidance for the building design. Therefore, the predesign work requires the designer to analyze and select the site reasonably. In addition, it is necessary to conduct in-depth research on the target customers. At the same time, it is necessary to accurately position and predict the dynamic market, and then to have a thorough understanding of the norms and regulations. As a result, the predesign work enables the design to be analyzed in the context of the actual situation. Then, according to the data and information from various aspects, effective planning and argumentation are carried out, and corresponding decisions are made to provide guidance for the design. Overall, predesign is a process of rational planning of the design process. In fact, in the process of landscape design innovation, it is necessary to fully consider the requirements of the intelligent era. Therefore, multimedia and advanced robotics can continuously enhance the interaction and experience of urban landscape to make it integrate into the intelligent system of the future city. In other words, multimedia technology can enhance the new image of the city in an intelligent, digital, and humanized interactive experience. Especially in the landscape design process, the advent of computers has enabled landscape designers to use relevant design software to design their own works, thus giving them unlimited design possibilities. Virtual reality technology, as a form of computer technology, provides designers with a new creative experience in the design phase of a landscape project. To be specific, this technology allows designers to freely grasp the design space and scientifically compare the differences between design options to make the design more reasonable and complete. Therefore, this paper analyzes the differences in the general environment and concepts of 3D software virtual reality technology, starting from the characteristics of the application of 3D technology as an entry point. At the same time, this study uses the similarities and differences in technology to discover the vital role of using virtual reality technology to reconstruct the space and the impact of robots on modern architecture.

Along with the increase of electricity consumption in society, it means that the quality of power inspection gives higher requirements. The traditional manual inspection method is difficult to ensure the stability of checking quality. Without the popularization of manned distribution stations and smart grid methods, replacing manual inspection with electric power inspection robots can improve the inspection quality and inspection efficiency to a certain extent. Along with theimage processing process which is widely used in the robot system, visual impact is not only an effective way for us to obtain information but also the key reflection of the robot system intelligence. Unmanned aircraft as an extremely important robot has long been widely used in all walks of life. Power inspection is the most common use of unmanned aircraft robot inspection. However, due to extreme criteria such as bad weather, relative motion, and shaking of imaging equipment, inspection images are obtained ambiguously. The quality of the inspection image is related to the timely understanding, analysis, and judgment of the power engineering quality inspection database. In the paper, the unmanned aircraft power inspection robot as a scientific research foothold, according to explore the key technology of anti-internet technology to clear the image ambiguity, proposed a complete disambiguation optimization calculation method. The image denoising optimization calculation method based on the directional characteristics of time-frequency analysis and edge maintenance is selected to carry out the finding of the image, which reasonably solves the image resolution bottleneck problem of GIS in unmanned aircraft robot line inspection. Meanwhile, with the emergence of nanorobots in the 21st century, the application and analysis of remote sensing image processing technology in the field of robotic power inspection in this paper will also bring new vitality and vigor to the research of nanopower inspection robots and solve the problem of unclear images existing in nanorobots.
