Abstract

The invention discloses a mechanical arm. The mechanical arm comprises a first arm component, a second arm component, a pivot base, a third arm component and a drawn wire, wherein the second arm component is rotationally connected with the first arm component through a first rotating shaft; the first rotating shaft is substantially perpendicular to the length directions of the first arm component and the second arm component; the pivot base is rotationally connected with the second arm component and the third arm component; and the drawn wire is fixedly connected with at least one of the first arm component, the second arm component and the third arm component. The mechanical arm can enable the arm component connected with the drawn wire to rotate corresponding to the other arm component through pulling the drawn wire; and under the condition, a driving device for pulling the drawn wire can be not limited to arrange in the rotary connecting place of the two arm components, but is arranged out of the mechanical arm to relieve self weight of the mechanical arm and to simplify the structure of the mechanical arm.

Description

technical field [0001] The invention relates to the field of robots, in particular to a mechanical arm and a robot. Background technique [0002] The driving device of the existing mechanical arm is generally arranged at the joint where the two arm components are rotatably connected, resulting in excessive weight of the mechanical arm and complex joint structure. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a kind of mechanical arm and robot. [0004] The mechanical arm of the embodiment of the present invention includes: a first arm member; a second arm member, the second arm member is rotationally connected with the first arm member through a first rotating shaft, and the first rotating shaft is substantially perpendicular to the The length direction of the first arm member and the second arm member; the pivot seat; th...
