AI Technical Summary

Technical Problem

Existing dexterous hands vary greatly in size and shape due to different models and structures, which requires custom-made tactile sensors to match them, resulting in long development cycles and high costs.

Method used

The design incorporates a dexterous hand skin, employing multiple thin-film structures to cover the distal and middle phalanges of the fingers and the surface of the palm. Adjacent thin-film structures are connected by connecting lines, the length of which is greater than the spacing between the thin-film structures or is an elastic connecting line. Furthermore, the conductive particles in the conductive silicone layer are arranged in a gradient density to form gradient conductivity.

Benefits of technology

This enables rapid adaptation of dexterous hand skin to dexterous hands of different structures and sizes, shortening the development cycle, reducing costs, and improving the force detection sensitivity and reliability of the sensor's edge and center regions.

Abstract

This application relates to the field of robotics technology, and more particularly to a dexterous hand skin for embodied intelligence training grounds, a method for manufacturing the same, and a dexterous hand. The dexterous hand skin comprises multiple thin film structures respectively disposed on the distal phalanx, middle phalanx, and palm surface of the dexterous hand; connecting lines connect the thin film structures on the distal phalanx, middle phalanx, and palm, wherein the length of the connecting line between adjacent thin film structures is greater than the spacing between the corresponding thin film structures, and / or the connecting lines are elastic connecting lines; the thin film structure includes a stacked upper electrode layer, a conductive silicone layer, and a lower electrode layer, wherein the density of conductive particles in the conductive silicone layer is gradient-distributed, and the density of conductive particles in the edge region of the conductive silicone layer is greater than the density of conductive particles in the center region of the conductive silicone layer. By using length redundancy or elastic material for the connecting lines, it can quickly adapt to different dexterous hands, improving its adaptability.
