Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] figure 1 It is a top view sectional structure diagram of the hemispherical differential spherical robot. figure 2 It is the front structural diagram of the hemispherical differential spherical robot. As shown in the figure, the spherical robot consists of a left hemispherical shell 1 and a right hemispherical shell 8 to form a spherical shell. A main frame 2 is installed in the spherical shell. The main frame 2 consists of two rectangular frames fixed to each other. The two rectangular frames are arranged perpendicular to each other, the frame on the vertical plane is called the vertical rectangular frame, and the frame on the horizontal plane is called the horizontal rectangular frame. The joints on both sides of the two rectangular frames correspond to the tops of the two hemispherical shells. A left support seat 18 and a right support se...

Abstract

The invention provides a hemispheric differential spherical robot. The spherical robot comprises an outer spherical shell formed by a left hemispheric shell and a right hemispheric shell; a main frame is arranged in the spherical shell; a left support seat and a right support seat are respectively fixed on the inner side at the top of the left hemispherical shell and the right hemispherical shell; the support seats are connected with the connection positions of two corresponding rectangular frameworks by a support frame; one end of the support frame is fixedly connected with the main frame and the other end thereof is connected with the support seats in a slide way; an electric motor support plate is arranged at the connection position between the support frame and the main frame and used for fixing an electric motor with long axis; the electric motor with long axis is connected with the support seats by a bearing which is arranged in the support frame in a penetrating way; and the main frame is internally provided with at least one heavy pendulum which is arranged on a vertical plane and fixed with the main frame through the frame of the heavy pendulum. The hemispheric differential spherical robot divides the spherical shell into two mutually independent hemispheric shells for respective driving and controlling, thus having more flexible and accurate controllability of motion orientation.

Description

technical field [0001] The invention relates to a spherical robot, in particular to a spherical robot which is divided into left and right hemispheres for differential drive so as to have omni-directional rolling capability, and belongs to the technical field of intelligent robots. Background technique [0002] In the current space exploration, military, industry and home services, mobile robots are more and more widely used. The spherical robot is a kind of mobile robot. The contact between the spherical robot and the ground point belongs to rolling friction, the resistance is small, the movement and steering are flexible and convenient, and it has the characteristics of omnidirectional movement and zero turning radius. Now various smart home appliances are gradually entering ordinary families. Among them, the spherical robot has a novel shape and a special way of movement. It is not afraid of falling over, will not catch other things, and can turn flexibly. It is suitable ...
