Summary: Robotic manipulation is undergoing a profound paradigm shift due to increasing demand for flexible manufacturing systems and advancements in sensing, learning, optimization, and hardware. This shift requires robots to observe and reason about their workspace and possess the skills to complete various assembly processes in weakly-structured settings. Enabling on-site teaching of robots while managing the complexity of perception, control, motion planning, and reaction to unexpected situations remains a significant challenge.

Summary: This study investigated the temperature distribution during ultrasonic welding of carbon fiber-reinforced polypropylene (CF/PP) using a thermographic camera. Single lap shear tests were performed on the welded joints. The experiments confirmed that the sonotrode amplitude affects the temperature distribution and joint quality, which in turn affects the failure mode. The half-width method was applied to assess the spread of the high-temperature region centered on the welding interface.

Summary: By employing a multi-scale modeling scheme, researchers have successfully resolved the stress distributions within the S2 layer at different moisture levels. They found that the shear stress on the fibril-matrix interface is smaller due to the heterogeneous nature of the microfibrils. Additionally, they demonstrated that the stress developed during dehydration is larger than during hydration, attributed to the softening of the amorphous polymers in the matrix upon water adsorption.

Summary: In this study, a deep learning framework that combines interpretability and feature fusion is proposed for real-time monitoring of pipeline leaks. The proposed method extracts abstract feature details of leak acoustic emission signals through multi-level dynamic receptive fields and optimizes the learning process of the network using a feature fusion module. Experimental results show that the proposed method can effectively extract distinguishing features of leak acoustic emission signals, achieving higher recognition accuracy compared to typical deep learning methods. Additionally, feature map visualization demonstrates the physical interpretability of the proposed method in abstract feature extraction.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.
