Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, the robotic bionic finger of the present invention includes a cage 1 and an airbag 2 . The airbag 2 is a long cylindrical structure, the cage 1 is a long sheet structure, made of elastic material, and is curved in a natural state, and the cage 1 is axially attached to the airbag of the airbag 2 wall, so that the airbag 2 is curved in a natural state.

[0018] Such as figure 2 As shown, the retainer 1 includes an integrally formed base body 11 and a top cover 12 , the top cover 12 is attached to the end of the airbag 2 , and the elastic deformation of the base body 11 is greater than that of the top cover 12 . The base body 11 is stamped from an elastic metal sheet, which can be easily deformed and can be straightened; the top cover 12 is made of a metal material with good rigidity, which will not ...

Abstract

The invention discloses a robot bionic finger. The robot bionic finger comprises a holding frame and an air bag, the air bag is a long-strip cylindrical structure, the holding frame is a long-strip sheet-shaped structure and made of elastic materials, the holding frame is in a bending shape in a natural state, and the holding frame is attached to an air bag wall of the air bag in the axial direction so that the air bag is in a bending shape in the natural state. According to the robot bionic finger, single-air-bag driving is employed, the structure is simple, the control is easy, the air bag is attached to the holding frame, a certain rigidity can be maintained when the air pressure of the air bag is small, the wall thickness of one side of the air bag with small section curvature is greater than the other side so that when the pressure is increased, the expansion amount of the thin wall side is larger than the expansion amount of the thick wall side, the finger can be driven to keep straight, spring wires are embedded into the air bag so that radial deformation of the air bag in the expansion process is reduced, the air bag can be recovered during pressure reduction, the air bag can still maintain the initial shape during negative pressure, and the outside of the air bag is provided with a plurality of protruding points capable of increasing the friction of the air bag so that the grabbing of articles is facilitated.

Description

technical field [0001] The invention relates to the field of robots, in particular to a robot bionic finger. Background technique [0002] Robot technology is developing rapidly. At present, most humanoid manipulators are based on the mechanical structure to realize the bending of the finger joints. The fingers of the manipulator are composed of multiple joints connected in series, and the mechanical structure is driven by micro motors, pushing cylinders, and wire rope traction to realize the contraction of the fingers. , to achieve the purpose of precise control, but the structure is relatively complex, the control process is cumbersome, the application of the function of only grabbing items is less economical, and the cost is high, the mechanical structure is complex, easy to damage, and the control is difficult to meet the flexible control requirements. Therefore, there is a need for a robot with low control difficulty and simple structure and materials to grasp objects. ...
