Problems solved by technology

However, most traditional robots are composed of rigid mechanisms through assembly, which have the disadvantages of complex structure, limited flexibility, poor safety and human interaction, and low environmental adaptability.
[0003] In some special application scenarios, such as grasping and handling of fragile or soft objects, or detection work on rough and irregular roads or narrow pipelines, the traditional Rigid robots are difficult to achieve similar tasks, while soft robots have unique advantages in such working conditions

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as Figure 1 to Figure 4 As described, a serial modular pipeline crawling soft robot includes:

[0043] Pneumatic telescopic unit 3, the pneumatic telescopic unit is configured to only extend axially when inflated;

[0044] The pneumatic expansion unit 1 is connected and arranged at both ends of the pneumatic expansion unit through the connecting part 2, and the pneumatic expansion unit is set so that it can only expand radially when inflated. Corresponding modules can be connected by thread or pin, which can be installed more conveniently and firmly. In this embodiment, the thread method is adopted.

[0045] Specifically, in a feasible embodiment, the pneumatic expansion unit 1 includes:

[0046] The radial expansion main body is columnar as a whole, made of flexible material and has a closed air cavity inside;

[0047] Two pos...

Abstract

The invention discloses a series type modular pipeline crawling soft robot. The series type modular pipeline crawling soft robot comprises a pneumatic stretchable unit and pneumatic expansion units, wherein the pneumatic stretchable unit is arranged to only extend in the axial direction when being inflated, the pneumatic expansion units are connected with the two ends of the pneumatic stretchableunit through connecting portions, and the pneumatic expansion units are arranged to only expand in the radical direction when being inflated. The robot is mainly applied to the occasion of pipeline crawling, is mainly characterized in being modular, and has the advantages of being convenient to replace, flexible to assemble, powerful in function, simple in structure, easy to operate and the like,a wide variety of robot configurations can be combined through simple selection and series assembly of modular assemblies, and therefore, the robot has different functions and can better adapt to a wide variety of working environments and tasks.

Description

technical field [0001] The invention belongs to the field of robots and relates to a serial modular pipe crawling soft robot. Background technique [0002] With the development of science and technology, robot technology has developed rapidly, and has been widely used in industrial production, space exploration, cargo transportation, medical surgery, disaster relief, and national defense and military industries, achieving a high level of automation. Save labor cost. However, most traditional robots are composed of rigid mechanisms through assembly, which have the disadvantages of complex structure, limited flexibility, poor safety and human interaction, and low environmental adaptability. [0003] In some special application scenarios, such as grasping and handling of fragile or soft objects, or detection work on rough and irregular roads or narrow pipelines, the traditional Rigid robots are difficult to achieve similar tasks, and soft robots have unique advantages in such...
