Problems solved by technology

[0004] At present, there are many studies on nanoscale positioning mechanisms and kinematic mechanisms, and there are also many studies on the application of flexible hinge mechanisms to nanoscale positioning platforms. However, the positions of most mechanisms are fixed and cannot adapt to occasions that require changing working positions. Use is limited

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0017] Such as figure 1 As shown, the high-precision flexible hinge peristaltic robot includes a forefoot deformation mechanism, a trunk peristaltic mechanism, and a rear foot deformation mechanism. The forefoot deformation unit 1 and the forefoot piezoelectric ceramic 3 form an interference fit connection through the bosses at both ends of the forefoot deformation unit 1 . The forefoot rear deformation unit 2 and the forefoot rear piezoelectric ceramic 4 form an interference fit connection through the bosses at both ends of the forefoot rear deformation unit 2 . The front foot deformation unit 1 and the front foot rear deformation unit 2 are integrally processed, designed and manufactured. The up...

Abstract

The invention discloses a high-precision flexible hinge wriggling robot which comprises a front foot deformation mechanism, a trunk wriggling mechanism, a rear foot deformation mechanism and the like. The front foot deformation mechanism and the rear foot deformation mechanism based on the notch type flexible hinge mechanism are similar in structure and are symmetrically distributed relative to the trunk wriggling mechanism, and the two sets of electromagnets are located at the two ends of the front foot deformation mechanism and the rear foot deformation mechanism respectively. The front foot deformation mechanism and the rear foot deformation mechanism work alternately through charging and discharging of the piezoelectric ceramic and on-off of the electromagnet to drive the trunk creeping mechanism to store and release deformation energy, the front foot deformation mechanism or the rear foot deformation mechanism is driven by the piezoelectric ceramic, and micro-nano-scale real-time advancing and retreating can be achieved. And the urgent requirements in the fields of micro-nano positioning, operation and the like with position change requirements can be met.

Description

technical field [0001] The invention relates to a flexible bionic robot, in particular to a high-precision flexible hinge peristaltic robot. Background technique [0002] With the continuous development of science and technology, especially nanotechnology, in the fields of industry and aviation manufacturing, micro-cell operation, microelectronics manufacturing, bioengineering and other fields, there is an urgent need for micro-nano-level positioning accuracy micro-motion mechanisms and micro-nano-level motion precision actuators. . [0003] The flexible hinge mechanism has many advantages, such as simple structure, overall design and manufacture, free from assembly, no gap, no lubrication, and has natural advantages that rigid mechanisms do not have. The flexible hinge mechanism can achieve high-precision displacement through the elastic deformation of the flexible hinge unit, and has nano-level positioning accuracy and motion accuracy. Now it has been widely used in moder...
