Problems solved by technology

In this structure, the upper, middle and lower neck racks and the three motors are superimposed in series, resulting in a complex structure and large volume, especially in the vertical direction, which easily leads to an excessively long neck length. reduce the similarity with people
In addition, the three motors connected in series and their frame structure have great mutual interference, and the stability of the neck movement is poor; the lower motor needs to bear the weight of the middle and upper motors and the middle and upper frame at the same time, which requires a large power and increases the manufacturing difficulty. and volume, and reduces service life

Abstract

The invention discloses a robot neck mechanism. The robot neck mechanism comprises a neck lower rack (1) which is connected with a shoulder (11) and a neck upper rack (8) which is connected with a head (9). A head rotating motor (7) is installed on the neck upper rack (8). A shaft of the head rotating motor (7) is connected with the head (9). The rear of the neck upper rack (8) is connected with an upper plate of the neck lower rack (1) through a universal joint (10). The left side and the right side of the front of the neck upper rack (8) are respectively connected with rotating shafts of stepping motors (2) on the left side and the right side on the neck lower rack (1) through a ball joint connecting rod mechanism. The robot neck mechanism is small in size, compact in structure, high in human similarity, good in moving stability and flexibility, easy to manufacture, and long in service life.

Description

technical field [0001] The invention relates to a robot neck mechanism. Background technique [0002] With the advancement of robot technology, there are more and more domestic service robots, and the anthropomorphic degree of robots is gradually pursued, especially the head movement. Since the human head movement is a three-degree-of-freedom rotational movement under the control of the neck, in order to realize the three-degree-of-freedom free rotation of the robot's head, the neck mechanism must be required to be able to realize the three-degree-of-freedom free rotation. The existing robot neck mechanism usually realizes the rotation on one degree of freedom by one motor; three motors are installed on the upper, middle and lower neck frames in series, and the three motors work together to realize three degrees of freedom rotation. In this structure, the upper, middle and lower neck racks and the three motors are superimposed in series, resulting in a complex structure an...
