Abstract

The invention discloses a method for preparing a micro-driven robot arm. By implanting a sensor into a driving structure, the integrated preparation of the two is realized, the preparation process is simplified, and the response hysteresis is eliminated; at the same time, a composite piezoelectric material composite layer is used. , forming a sensor with high deformation detection sensitivity.

Description

technical field [0001] The invention relates to the field of micro-drive devices, in particular to a method for preparing a micro-drive robot arm. Background technique [0002] Micro-driven robots have been applied to various aspects of industry, life and scientific research. They consist of a series of subsystems, such as sensors, actuators and controllers, which together form a robot capable of precise control. Numerous designs focus on the key components of the robot structure and actuators, in order to further improve the accuracy and stability of the operation. Drives can be divided into the following four categories, thermal drive, electric drive, optical drive and magnetic drive. Most of the existing micro-actuators adopt a separate structure of the driving device and the sensing device, which leads to the hysteresis of the detection and is not conducive to the response speed of the actuator; at the same time, for the discrete structure, multiple preparation process...
