Head driving module and spherical robot

Abstract

The invention discloses a head driving module positioned in a sphere of a spherical robot for controlling a head of the spherical robot. The head driving module comprises a rotating base, a rocking rod mechanism and a shield; the rotating base is mounted on a main bracket in the sphere, and is fixed with a first rotating shaft; one end of the rocking rod mechanism is connected with the first rotating shaft, and the other end is connected with the shield; the rotating base drives the rocking rod mechanism and the shield to rotate with the main bracket as a rotating center; the rocking rod mechanism and the shield swing corresponding to the main bracket with the first rotating shaft as a fulcrum; the shield is butted against the inner surface of the sphere, and is magnetically connected with the head; the shield is rotationally connected with the rocking rod mechanism; and the head and the shield are relatively static to enable the head to rotate on the surface of the sphere through the shield. The invention further discloses a spherical robot. The position of the head is variable to satisfy the use requirements of a family robot.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a head drive assembly and a spherical robot. Background technique [0002] A spherical robot refers to a robot that uses the rolling of a sphere to achieve movement. It can move in all directions, has a single point of contact with the ground, has small frictional resistance, high energy utilization efficiency, and has the characteristics of a tumbler, which can avoid the dumping failure that is easy to occur in conventional robots. stable phenomenon. The important parts of the robot are all contained inside the sphere, which is well protected by the sphere shell and is not easy to fail due to damage. Taking appropriate sealing measures can make the shell of the spherical robot have waterproof ability, and then it can be used under relatively bad weather conditions, and has all-weather adaptability. Further, the spherical robot generally also includes a head located outside the ...
