Robot arm structure

Abstract

The invention relates to the technical field of robots, and discloses a robot arm structure. The robot arm structure comprises a shoulder, a first arm, a second arm, a third arm, a first driving mechanism, a second driving mechanism, a third driving mechanism and a fourth driving mechanism; the shoulder, the first arm, the second arm and the third arm are sequentially and rotationally connected, and the first driving mechanism, the second driving mechanism, the third driving mechanism and the fourth driving mechanism drive the shoulder, the first arm, the second arm and the third arm to rotate; and four freedom degrees are included, wherein the shoulder is used for being rotationally connected to the robot body so as to achieve front-and-back swing of the overall arm structure, the first arm can rotate around the shoulder to swing to the inner and outer sides of a robot, the second arm rotates around the first arm to achieve lifting or placing of the arm structure, and the third arm rotates around the second arm so as to enable the third arm to rotate to the left and right sides. The robot arm structure is of a four-freedom-degree structure, the structure and the wine bottle grabbing structure are installed on the robot together, a series of wine pouring work can be completed, and the wine pouring efficiency is high.

Description

Technical field [0001] The invention relates to the technical field of robots, in particular to an arm structure of a robot. Background technique [0002] Mechanical automation is the development trend of human activities. A robot is a machine device that automatically performs work. It is used to assist or replace human work. It can not only receive human commands, but also run pre-arranged programs, or act according to principles and guidelines formulated with artificial intelligence technology. [0003] Currently, there is a performance robot on the market that 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 maker or automatic beverage machine. The robot must drag a pipe to walk. It occupies an automatic tea machine or automatic beverage machine during work, and the robot walks slowly. It is low, even lower than manual tea or alcohol pouring; [0005] 2. High R&D c...
