The invention relates to a porous double-layered fluid self-adaptive
robot hand device and belongs to the technical field of
robot hands. The porous double-layered fluid self-adaptive
robot hand device comprises a substrate, an air inlet, an external bowl-shaped supporting piece, an internal bowl-shaped supporting piece, a first flexible film, a second flexible film, a
piston cylinder
assembly and the like. A multi-dimensional self-adaptive active grasping function is comprehensively achieved by means of positive and negative pressures provided by an air source, the
piston cylinder
assembly, small holes in the first flexible film, a porous flexible material, the internal bowl-shaped supporting piece, the external bowl-shaped supporting piece, a fluid and the like, so that objects of different shapes and dimensions can be self-adaptively grasped. The porous double-layered fluid self-adaptive
robot hand device can be adaptive to the object in multiple directions to obtain the multi-dimensional self-adaptive effect, and is high in grasping stability. By combining the advantages of the spherical self-adaptive hand and a sucking disc, the porous double-layered fluid self-adaptive
robot hand device provided by the invention not only can be adaptive to grasp an object with a counteractive surface, but also can be adaptive to grasp an object without the counteractive surface, and is large in grasping range and high in grasping weight; and the porous double-layered fluid self-adaptive
robot hand device is simple in structure, low in cost and easy to control.
