Small rope-driven mechanical arm

Abstract

The invention discloses a small rope-driven mechanical arm. The small rope-driven mechanical arm comprises a mechanical arm body and a control system. The mechanical arm is composed of a hollow flexible mechanical arm body and a plurality of driving ropes, and the driving ropes are evenly distributed in the mechanical arm body in a circle. The control system comprises a fixed base A and driving modules M1, M2, M3, M4, N1, N2, N3 and N4, and the driving modules M1, M2, M3, M4, N1, N2, N3 and N4 and the driving ropes are fixed to the base A in The driving module is provided with a buffering module, and the tail end of a driving rope led out of the flexible mechanical arm is fixed into the buffering module. When the mechanical arm suddenly changes in the non-autonomous posture, the buffer module can automatically take up and release the driving rope to adapt to the sudden change in the posture of the mechanical arm so as to protect the mechanical arm. According to the rope-driven mechanical arm, the driving modules and the base A are fixed through the quick release design, the driving modules are relatively independent, quick replacement can be achieved, and the rope-driven mechanical arm has the beneficial effects of being small in size, flexible in movement, safe and stable and can well meet the refined operation requirements in the fields of medical treatment, scientific research and the like.

Description

technical field [0001] The invention relates to the field of mechanical arms, in particular to a small rope-driven mechanical arm. Background technique [0002] With the development of science and technology and social progress, various fields are becoming more and more refined operations, and the application scenarios of flexible manipulators are becoming wider and wider. However, traditional flexible manipulators are mostly rigid control, and their stability and adaptability to complex environments are relatively low. Therefore, the present invention proposes a small rope-driven mechanical arm with a buffer, which has high stability and safety, and can be well adapted to complex and changeable application environments. SUMMARY OF THE INVENTION [0003] In order to meet the needs of refined operations in the fields of medical treatment, scientific research and other fields, the present invention provides a small rope-driven manipulator, which is a rope capable of dexterou...
