Spherical robot

Abstract

The embodiment of the invention provides a spherical robot. The robot comprises a spherical shell, a head assembly and a head driving assembly, wherein the head assembly is arranged on the outer surface of the spherical shell, and the head driving assembly is contained in the spherical shell. The head driving assembly comprises a fixing support, a joint bearing, a first connecting rod, a guiding rail component, a guiding slide block, a first driving unit, a second driving unit and a shield, wherein the outer ring of the joint bearing is fixed to the fixing support, and the center of the joint bearing coincides with the sphere center of the spherical shell; the first connecting rod penetrates the inner ring of the joint bearing and is fixed to the inner ring, the other end of the first connecting rod is connected to the guiding slide block in a rotational mode, and the guiding slide block is installed on the guiding rail component, so that the first connecting rod and the shield rotate around the joint bearing, and the head assembly is driven to move on the outer surface of the spherical shell. According to the spherical robot, the effect that the head assembly is independently driven to move on the outer surface of the spherical shell can be achieved.

Description

Technical field [0001] The invention relates to the technical field of robots, in particular to a spherical robot. Background technique [0002] A spherical robot is a robot in which a drive mechanism, a controller, etc. are installed inside a spherical shell, and the spherical shell is driven to roll through the inner drive mechanism. The contact mode of the spherical robot with the ground is point contact, which can walk in all directions; it has a zero turning radius and is flexible and convenient to move and turn. In addition, the spherical robot has a novel shape and a special movement mode. It is not afraid of tipping over or catching other things. It turns flexibly and is suitable for working in a special and complex environment like a family. [0003] Most of the existing spherical robots are satisfied with the walking function, and few spherical robots include a head; or the structure on the head is single, and the head cannot be controlled independently, especially when ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing spherical robots are satisfied with the walking function, and few spherical robots include a head; or the structure on the head is single, and the head cannot be controlled separately, especially when the spherical robot is stationary, the head cannot be controlled independently. rotation, which greatly reduces the flexibility and manipulation experience of the spherical robot
