Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0030] The invention provides an intelligent snake-arm robot system based on memory alloy, which includes: a snake-arm, a wire-receiving module, a driving module and a remote control module.

[0031] The snake-shaped arm part is composed of a plurality of snake-shaped arm joints, and the two ends of the snake-shaped arm are respectively connected with the external terminal 11 and the top terminal 12 . Such as Figure 1a One of the snake-shaped arm joints shown includes: memory alloy cable 0, connecting frame 1, memory alloy wire hole 2, wire through hole 3, lock nut 4, middle through hole 5, set screw 6, nylon rod 7, wire 8. Fasten external thread 9 and set screw hole 10. exist figure 2 , image 3 It can be seen from the figure that there are three memory alloy wire holes 2 distributed at 120° in the circumferential direction on the connec...

Abstract

The invention discloses an intelligent snake-arm robot system based on memory alloy, which is composed of a snake-arm, a snake-arm take-up module, a drive module and a remote control module. The snake-shaped arm is composed of a plurality of snake-shaped arm joints with the same structure connected end to end. The initial state of the snake-shaped arm is wound in the snake-shaped arm take-up module; the snake-shaped arm joint is composed of memory alloy, nylon rods, wires, and connecting frames. The voltage is applied to both ends of the memory alloy through the wire, so that the temperature of the memory alloy itself changes, and the stretching length of the memory alloy is changed to change the position and posture of the snake-shaped arm joint in the entire space. The intelligent snake-arm robot system of the present invention can realize the separation of control and drive, and can be controlled remotely, so that the snake-arm robot can be applied to various complex environments such as medical treatment and disaster relief. The invention has the characteristics of simple operation, high precision, intelligence and wide application scenarios.

Description

technical field [0001] The invention relates to an intelligent snake-arm robot system based on a memory alloy, in particular to the design and control of a snake-arm robot based on a memory alloy, and belongs to the technical field of intelligent robots. Background technique [0002] In recent years, with the vigorous development of robot-related technologies, the requirements for the scope and ability of robots have been continuously improved. Traditional robots are difficult to apply to scenes with complex environments and limited space due to their huge size and limited degrees of freedom. Under such a research background, a series of snake-arm robots with exquisite structure and high degree of spatial freedom emerged as the times require. They can be better applied to complex environments and solve many problems that traditional robots cannot solve. The high degree of freedom and flexibility of the snake-arm robot, and its ability to be applied in complex environments, ...
