Abstract

The invention discloses an inchworm-type micro-movement walking robot. The robot is composed of two clamping units and one driving unit, wherein the driving unit is composed of two symmetrically arranged driving branch chains and two pairs of right-angle flexible hinges. The branch chain is composed of two lever structures, the drive unit and the two clamp units are connected by bolts, and the drive unit can perform reciprocating micro-displacement movement relative to the clamp unit; the clamp unit consists of two symmetrically arranged drive branch chains and Composed of 2 pairs of right-angle flexible hinges and a base plate, 2 clamping units are symmetrically connected to both ends of the drive unit through bolt holes. One end of the clamping unit is driven and its base is fixed, the driving structure is extended and the other clamping unit is driven to move in a straight line, imitating the law of motion of the bionic inchworm. The present invention adopts three piezoelectric stacks, utilizes the friction effect between the clamp unit and the ground to realize clamping, and can convert the action displacement of the piezoelectric stacks into an effective driving displacement.

Description

technical field [0001] The invention relates to an inchworm-type micro-moving walking robot, which belongs to the field of precision micro-operation and is mainly used in the fields of high-tech science and technology such as precision engineering, micro-electromechanical systems (MEMS), microelectronic engineering, biological engineering, and robots. Background technique [0002] With the rapid development of micro-electromechanical systems (MEMS) technology, micro / nano technology and robotics, traditional micro-robots are unable to meet the requirements of ultra-precision and high-precision positioning due to their working principles and mechanical structures. Ultra-precise micro-robots with nano-level and nano-level precision can realize their functions. The inchworm-style walking robot is a robot that imitates the motion law of the natural biological inchworm and can realize micro-displacement accumulation to obtain a large stroke. However, at present, walking robots st...
