Mechanical arm structure of robot

Abstract

The invention relates the technical field of robots, and discloses a mechanical arm structure of a robot. The mechanical arm structure comprises a arm structure and a mechanical claw structure, wherein the arm structure comprises a shoulder part, a first arm, a second arm and a third arm which are rotationally connected with one another in sequence to form four degrees of freedom, wherein the shoulder part is used for being rotationally connected to a robot body so as to realize front-and-back swing of the whole arm structure; the first arm can rotate around the shoulder part to realize the swing toward the inner side and outer side of the robot; the second arm can rotate around the first arm to enable the arm structure to be lifted or put down; the third arm can rotate around the second arm to enable the third arm to rotate in left-and-right sides; the mechanical claw comprises a clamping claw which is rotatably arranged on the third arm; and the clamping claw can rotate to realize grabbing of wine bottles. The mechanical arm structure of the robot has the beneficial effects that after the wine bottles are grabbed by the mechanical claw, and a series of actions of wine pouring canbe completed by utilizing the four-degree-of-freedom arm structure to move the wine bottles; the wine pouring efficiency is high, and wine pouring is not required to be carried out by dragging a pipeline.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot manipulator structure. Background technique [0002] Mechanical automation is the development trend of human activities. A robot is a machine device that performs work automatically and is used to assist or replace human work. It can not only receive human instructions, but also run pre-programmed programs, and can also act according to principles and programs formulated with artificial intelligence technology. [0003] At present, there is a performance robot on the market, which is used to pour tea or wine, but this robot has the following disadvantages: [0004] 1. Low efficiency: First of all, it cannot be separated from the automatic tea machine or automatic wine machine. The robot must drag a pipe to walk. It occupies an automatic tea machine or automatic wine machine during work, and the robot walks slowly, and the efficiency is low. It is low, even lower than man...

AI Technical Summary

Problems solved by technology

[0004] 1. Low efficiency: First of all, it cannot be separated from the automatic tea machine or automatic wine machine. The robot must drag a pipe to walk. It occupies an automatic tea machine or automatic wine machine during work, and the robot walks slowly, and the efficiency is low. It is low, even lower than manual pouring of tea or wine;

[0005] 2. High R&D costs: The robot has many upper and lower joints, which are cumbersome, and it mainly uses humanoid walking, which adds R&D costs to the control algorithm.
