Abstract

The present invention relates to the technical field of target catching and specifically discloses a flexible catching mechanism, specifically including a flexible capsule device, a phase change magnetorheological material, a surface microstructure, an electromagnet, a heating structure, a piston structure and a support structure; wherein the flexible capsule device is filled with the phase changemagnetorheological material; the surface microstructure is disposed on the outer surface of the upper end of the flexible capsule device; the heating structure is disposed inside the flexible capsuledevice; the piston structure is disposed on the lower end of the flexible capsule device, and is axially movable along the un-down direction of the flexible capsule device; the support structure is used for supporting the flexible capsule device; and the piston structure and the support structure are configured to seal the flexible capsule device. The invention provides the novel catching mechanism, which can catch targets having different shapes, surfaces and motion characteristics.

Description

technical field [0001] The invention relates to the technical field of target capture, in particular to a flexible capture mechanism. Background technique [0002] At present, the success rate of capturing the explored target in a special environment is an important guarantee for the completion of the exploration task. Traditional contact manipulation is limited by the contact method, which has strict requirements on the structure and surface properties of the connected target, and cannot meet the control requirements for unknown targets (unknown surface properties, unknown motion characteristics, and unknown inertia parameters). Therefore, it is of great engineering significance to carry out research on flexible capture mechanisms that do not depend on target characteristics, and to solve the problem of stable capture for targets with different surface characteristics (roughness, structural characteristics), different motion characteristics, and variable inertia characteris...
