Aiming at the problem that the stability of the quadruped robot is decreased as its leg momentum is too high, a stable balance adjustment structure of the quadruped robot based on the bionic lateral swing posture is proposed. First, the leg structure of the quadruped robot is improved and designed by using the mechanism of the lateral swing posture of the leg of the hoof animal. Then, the D-H method is used to construct the corresponding leg kinematics model and determine the generalized coordinates of the leg joints in the lateral swing posture. The torque expression of the quadruped robot when it is tilted is established. Based on the differential equation of momentum of the hip joint and its static stability analysis, the static stability conditions in the upright posture and the bionic lateral swing posture are given. Finally, the experimental simulation and comparative analysis of the upright posture and the lateral swing posture of the quadruped robot are proposed by using the Adams virtual prototype technology. The simulation results show that as the angle of lateral swing increases, the peak value of the positive flip torque of the quadruped robot body increases accordingly, while the degree of tilt decreases accordingly, which shows that the bionic lateral swing posture of the quadruped robot has higher static stability than the traditional upright posture. This research provides a technical reference for the design and optimization of the offline continuous gait of the robot and the improvement of stability.

Abstract. With the application of UAV Oblique photography, rapid 3D real-time modeling based on aerial image data has become a new technology in the field of 3D modeling. In view of the current poor mapping and inability to reuse the basic surveying and mapping data in the publicity and display, dynamic planning, etc., based on the UAV photogrammetry technology that is used to rapidly and accurately collect image data of the Longji terraced scenic spot in Guilin, Guangxi, this paper develops a platform by 3D real-time modeling technology with the combination of the high-tech such as digital mapping to realize the three-dimensional navigation and smart tourism of the scenic spot. The practical results show that the application can better meet the actual needs of high precision, large scale, wide audience, strong interaction, etc., which effectively alleviates the contradiction between the protection and utilization of cultural resources in cultural tourism, expands the cultural resources audience, and provides high-tech support to the cultural tourism.

The structural optimization of spherical reticulated shells is not only a problem of reducing of the steel consumption in the design-build contract mode. There are several objective functions in the question. We should also consider reduction in transport costs and storage charges of components, construction difficulty and construction period. The number of member types is used as a substitute for the secondary indicators by correlation analysis. The objective function is the number of member types and the steel consumption in the end. We carry out the bi-objective optimization by iterative experimental design. The operation process of the method is explained by a case study of 60-meter-span Kewitte single-layer spherical reticulated shell. The example shows this method reduces computational workload, and the convergence rate is fast.

The vigorous development of the cultural and creative industry has led to a large increase in the demand for cultural and creative product design talents. Many colleges and universities have set up cultural and creative design majors. However, with the change in consumers' demand, traditional cultural and creative products are in need of reform because of their monotonous and homogenous functions. As a new hot spot in the consumer market, smart products have been sought after by the cultural and creative industry in recent years. However, the current modes for cultivating such comprehensive talents in universities are still not perfect. This article starts with the current situation of the training of talents in cultural and intelligent product design, combining with the teaching experience accumulated in recent years, proposes a new idea of fostering the talents in cultural and intelligent product design based on the school-enterprise synergy education, taking the "practice, construction, examination, evaluation" as the approach.
