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 S-shaped arm robot system based on memory alloys. The intelligent S-shaped arm robot system is formed by an S-shaped arm, an S-shaped arm take-up module, a drivemodule and a remote control module. The S-shaped arm is formed by connecting multiple S-shaped arm joints of the same structure end to end, and the S-shaped arm is wound in the S-shaped arm take-up module in the initial state. The S-shaped arm joints are formed by the memory alloys, nylon rods, wires and connecting frames. Voltages are applied to the two ends of the memory alloy through the wires, the temperature of the memory alloys is changed, and the telescopic length of the memory alloys is changed so as to change the positions and postures of the S-shaped arm joints in the whole space. By means of the intelligent S-shaped arm robot system, control and drive are separated, remote control can be achieved, and the S-shaped arm robot can be suitable for medical treatment, anti-disaster rescue and various complex environments. The intelligent S-shaped arm robot system is simple in operation and has the advantages of being high in precision, intelligent and wide in application prospect.

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, ...
