Abstract

SignificanceSoft anthropomorphic dexterous hands, as a type of robot end effector composed of soft materials, are capable of achieving human-like grasping and manipulation abilities, and are characterized by high dexterity, outstanding environmental adaptability, and safety in the human-robot interaction. [Analysis] The performance of soft anthropomorphic dexterous hands in terms of dexterity and grasping operation capabilities was reviewed, followed by a detailed introduction and analysis of the research status of soft anthropomorphic dexterous hands in terms of driving methods, materials and manufacturing, flexible tactile sensing, modeling and control. Finally, the potential challenges and possible development directions faced by soft anthropomorphic dexterous hands were discussed, and emphasizing that improving their dexterity and tactile perception capabilities is a key focus of future research.

Abstract

Underwater launchers are typically employed for the deployment of pigging robots in subsea pipelines for the purposes of cleaning and inspection. Throughout the launching process, challenges related to vibration, damage, and other issues must be addressed and resolved. In this study, the launching process of the pigging robot is numerically simulated using Abaqus 2020. Utilising the Coupled Eulerian-Lagrangian (CEL) method, the Fluid-Structure-Interaction (FSI) model of the launching process was constructed. And the variation of parameters such as velocity, friction force and tilt angle at different inlet flow rates were analysed. The findings indicate a positive correlation between the average velocity of the pigging robot and the inlet flow rate. The factors such as friction, tilt angle, and offset distance are related to the motion process of the pigging robot. Furthermore, during the pigging robot's traversal through narrow pipe sections, the sealing discs undergo irregular deformation, generating a reaction force on the robot and inducing vibration. In conclusion, the analysis of the impact of inlet flow velocity on the motion behaviour of the pigging robot offers a theoretical foundation and reference for the successful launch of the robot.

Author

Liu, Shuhai and Liu, Shuhai

Abstract

In order to make the game industry chain be developed structurally, this paper designs a functional game industry expansion path based on VR realistic technology to enhance the interactivity of functional game industry expansion. The interactive 3D model is used to integrate the professional game engine and design the functional game expansion process. The motive of game expansion is guided by the ARCS model to support the construction of functional games. According to the VR realistic game experience, analyze the expandable paths from the modules of technological innovation and industrial integration in order to enhance the realistic experience of integrated industries in functional games. The simulation analysis of the expansion path of the functional game industry based on VR realistic technology shows that VR realistic technology improves the signal-to-noise ratio of functional games by 50% on average, height and cross-roll angle changes by 6.65f/ms and 6.79f/ms respectively, and the number of textures is up to 16.68MB. Therefore, VR realistic technology is beneficial to promote the transformation of the functional game industry it can ensure that the functional game industry steps into a sustainable and expandable track of transformation and upgrading.
