Bionic Chameleon Tongue Actuator

Abstract

The invention discloses a bionic chameleon tongue actuator, which comprises a frame, an adjustment mechanism, an ejection assembly and a reset assembly for resetting and retracting the ejected ejection assembly; the ejection assembly includes a fixed tailstock, a central support shaft, and a contraction sleeve , an ejection sleeve, and a first drive mechanism that provides driving power for the ejection sleeve; the reset assembly includes a plurality of shrinkage blocks that are connected to the telescopic sleeve and drive the telescopic sleeve to shrink along the axial direction of the central support shaft, and drive to shrink The second drive mechanism for shrinking the block, the end of the shrinking block is fixedly arranged on the fixed tailstock and a plurality of shrinking blocks are evenly arranged in the circumferential direction of the telescopic sleeve; the bionic chameleon tongue actuator of this technical solution can realize accurate detection of the target object. , Long-distance fast grabbing.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a bionic chameleon tongue actuator. Background technique [0002] In the existing technology, industrial grabbing robots can only be used in structured environments, and there are problems such as immovable bodies, no stretchability, and poor environmental adaptability. Extended, efficient gripping. With the development and cross-integration of biomechanics, mechanical design, bionic materials, optimal control and other disciplines, researchers have studied various grasping robots, but the traditional mechanical structure has a slow ejection speed, and the ejection direction is uncontrollable and difficult to control. . [0003] For example, Chen Xiaoping of the University of Science and Technology of China has developed a scalable and flexible robotic arm with a bionic honeycomb structure. By independently controlling the air pressure of the airbag modules arranged in each honeyco...

Problems solved by technology

[0004] All of the above robotic arms can grasp objects at medium and long distances, but the disadvantage is that it is difficult to control, and it is difficult to achieve precise pose control and fast grasping. Therefore, it is necessary to design a compact structure, simple control, and fast and accurate grasping. Robots are particularly important
