Embodiment Construction

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

[0017] like figure 1 As shown, the high-precision flexible hinge peristaltic robot includes a forefoot deformation mechanism, a torso peristalsis mechanism, and a hindfoot deformation mechanism. The forefoot front deformation unit 1 is connected with the forefoot front piezoelectric ceramics 3 through the protrusions at both ends of the forefoot front deformation unit 1 to form an interference fit connection. The forefoot and rear deformation unit 2 is connected with the forefoot and rear piezoelectric ceramics 4 through the bosses at both ends of the forefoot and rear deformation unit 2 to form an interference fit connection. The forefoot front deformation unit 1 and the forefoot rear deformatio...

Abstract

The invention discloses a high-precision flexible hinge peristaltic robot, which comprises a forefoot deformation mechanism, a trunk peristalsis mechanism, a hindfoot deformation mechanism and the like. The structure of the forefoot deformation mechanism based on the notch flexible hinge mechanism is similar to that of the hindfoot deformation mechanism. Regarding the torso peristalsis mechanism, the two sets of electromagnets are located at both ends of the forefoot and hindfoot deformation mechanisms, respectively. Through the charging and discharging of the piezoelectric ceramics and the power-on and power-off of the electromagnet, the forefoot deformation mechanism and the hindfoot deformation mechanism work alternately, driving the torso peristalsis mechanism to store and release the deformation energy, and the forefoot deformation mechanism or the hindfoot deformation mechanism is driven by the piezoelectric ceramics. It can realize real-time advance and retreat at the micro-nano level, and can meet the urgent needs of the fields of micro-nano positioning and operation with position change requirements.

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 industrial and aviation manufacturing, micro cell manipulation, microelectronics manufacturing, bioengineering and other fields, there is an urgent need for micro- and nano-positioning precision micro-movement mechanisms and micro- and nano-level motion precision actuators . [0003] The flexible hinge mechanism has many advantages, such as simple structure, integral design and manufacture, free from assembly, no clearance, and no need for lubrication. It 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. It has...
