Problems solved by technology

[0004] In the prior art, the robotic arm claw of the bionic octopus tentacles has limitations in the application field, and is currently mainly used for the clamping of small objects; for the efficient collection of complex-shaped specimens in the deep-sea field, and the dynamic recovery of submarines with complex structures on the fluctuating sea surface , it is very difficult to conveniently grab objects with complex shapes, variable sizes, and large size spans. Therefore, it is urgent to develop a method for efficiently grabbing objects with complex shapes.

Abstract

The invention discloses an efficient grabbing method for a complicated-shaped object. The method includes the following steps that A, mechanical arms of a mechanical gripper are opened and moved to the position above an object, and a second suction cup at the center of the bottom of a mechanical arm support makes contact with the surface of the object; B, the mechanical arms of the mechanical gripper are folded up so that all the mechanical arms can be wound on the object, and a plurality of first suction cups on the mechanical arms make contact with the surface of the object; and C, the firstsuction cups and the second suction cup generate negative pressure and are attached to the surface of the object. The complicated-shaped object can be grabbed, and the grabbing efficiency is high.

Description

【Technical field】 [0001] The invention relates to the technical field of manipulator clamping, in particular to a high-efficiency grasping method for complex-shaped objects. 【Background technique】 [0002] In the salvage and collection of underwater objects, as well as the grasping and transfer of engineering objects, considering the characteristics of the caught or transferred objects in different shapes and wide ranges of size and weight, using traditional manipulators for automatic operations is not only difficult to operate, but also traditional Traditional manipulators have great limitations due to the problems of large clamping force, uncontrollable grip, and small opening and closing range of the manipulator claws. [0003] With the development of the bionic robot field, the mechanical arm claw of the bionic octopus tentacles has a certain research basis. In the prior art, the mechanical arm claws of the bionic octopus tentacles are used to hold fragile small items (s...
