Control technology research of building wall spraying robot

Simplifying the palm into 21 joints essentially transforms the palm into a point cloud model. The common practice is to distribute each joint into a spatial coordinate system, and use combinatorial mathematics theory and social network graph theory for recognition32. When the 21 coordinate points change frequently, the aggregation pattern of these points becomes extremely […]

Edge computing-based proactive control method for industrial product manufacturing quality prediction

This section first analyzed the product’s quality characteristics and selected criticalquality-related parameters with correlation coefficients greater than the set threshold based on the correlation coefficients of industrial product quality inspection results and quality-related parameters. Established the SMOTE-XGBoost quality prediction model and optimized the hyperparameters. Finally, the active control method for prediction. Analysis of quality characteristics […]

Large rectangular cross-section tunnel undercrossing urban road by micro pipe jacking and joint assembly structure (MPJ & JAS) method in soft soils

Since MPJ & JAS tunnel is a novel and special elemental structure, it is necessary to carry out FE analysis and bending test to study and verify the structure performance as well as to determine the physical characteristics, failure behavior and strength for design. Bending test Experimental design The specimen is a segment of MPJ […]
