Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] Such as figure 1 As shown, a variable-length curved fully flexible manipulator structure includes an elastic rod 1 , a base 2 , a metal segment 3 , a spring 4 , a cable tie 5 , and a U-shaped buckle 6 .

[0019] The elastic rod 1, the base 2, and the metal segment 3 are the flexible supporting parts of the structure, the spring 4 is the flexible deformation part of the structure, and the cable tie 5 and the U-shaped buckle 6 are the fastening and locking parts of the structure.

[0020] Each metal segment 3 is a hollow circular segment, and each metal segment 3 is arranged along a vertical direction. A mounting hole capable of passing through the elastic rod 1 is provided on the circumference of the metal segment 3 .

[0021] Each vertically arranged elastic rod 1 passes through the installation hole on the metal segment 3 respectively, and the elastic rod 1 on the ...

Abstract

The invention discloses a variable-length bendable fully-flexible mechanical arm structure. The structure is a fully-flexible mechanical arm device having a posture controlled by elastic rods, capable of telescoping, and having a tail-end position capable of achieving any point in 360 degrees. The flexible mechanical arm device is composed of the elastic rods, a base, springs, metal section sheets, binding belts and U-shaped buckles. The four elastic rods are driven through slide tables of servo motors, thus posture control for the flexible mechanical arm and position control for a free end at the top are realized. The structure is reliable in stability and complete in function, and the tail-end position is capable of achieving any position in an outer envelope surface.

Description

technical field [0001] The invention relates to a fully flexible manipulator structure for controlling the terminal position and overall attitude, in particular to a fully flexible manipulator structure with variable length. Background technique [0002] Flexible mechanical structures have been proposed at home and abroad, usually to adapt to complex working environments and operational requirements. Traditional robotic arms are mostly connected by rigid rods, which take up a lot of space during movement. The advantage of the fully flexible robotic arm is that it can not only operate the end position, but also control the posture of the main body, which greatly improves the flexibility of work. The present invention adopts the elastic rod as the support structure, and the metal segment is used to limit the middle posture of the elastic rod. At the same time, the spring on the elastic rod coat is used to separate each segment, which improves the stability of the overall stru...
