Small flexible driving snakelike mechanical arm

Abstract

The invention discloses a small flexible driving snakelike mechanical arm which is characterized in that the small flexible driving snakelike mechanical arm comprises a mechanical arm body with six joints and a driving system, wherein the mechanical arm body comprises a rear arm body and a front arm body, and the rear arm body and the front arm body are each provided with a rotating joint and two yawing joints; the rotating joint is located at the rear ends of the yawing joints; the driving system comprises a driving source, a flexible transmission mechanism and a supporting piece, the driving source is arranged at the rear end of the joint body structure, the two rotating joints are directly driven, the two sets of yawing joints are indirectly driven, the middle flexible transmission mechanism is arranged in the direction from the rear end to the tip end, the body is in the flexible running trend through the transmission mechanisms, and the radial size of the structure is reduced; the transmission mechanism in the rear arm comprises improved belt rope transmission and gear transmission, and the transmission mechanism in the front arm is additionally provided with a flexible hose. The invention discloses a closed-loop flexible driving snakelike mechanical arm which is small in size, simple in structure and flexible in movement.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a small flexible driving serpentine mechanical arm. Background technique [0002] Robot technology has long been widely used in many industrial automation production fields, but most of the traditional industrial robots are only suitable for structured environments, such as workbenches, obstacles, operating objects and other spatial positions and layouts are known, and given The scope of the working space is large, and in the face of unstructured, narrow, and complex working environments, it is difficult for this type of robot to complete the corresponding tasks or even no longer applicable. Integrating snake-like technology into electromechanical technology, the developed snake-shaped robotic arm not only solves many unstructured special environment operation requirements in aviation exploration, national defense, medical treatment, agriculture, and industry, but also improves th...
