Embodiment Construction

[0019] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0020] combine figure 1 ~9. The motion mechanism of the hemispherical differential telescopic spherical robot of the present invention adopts a dual-motor drive structure, and the left and right hemispheres are each driven by a motor, and the principle of hemispheric differential is applied to realize the motion functions of the robot such as forward, backward, and in-situ steering. ; The telescopic mechanism of the robot uses the thread transmission principle of the lead screw to realize the telescopic expansion of the two shell hemispheres, which improves the flexibility and mobility of the robot. The telescopic mechanism of the robot adopts a double cross-shaped four-telescopic rod structure design, which increases the maximum load that the robot can bear when it is moving, and improves the stability and reliability of the internal structure of the robot when i...

Abstract

The invention aims to provide a hemisphere differential telescopic spherical robot. The hemisphere differential telescopic spherical robot comprises outer hemisphere shells, a driving part and a telescopic mechanism, wherein the driving part is of a double motor driving structure; left and right hemispheres are driven by a motor respectively; the movement functions such as advancing, retreating and pivot turning of the robot are realized by applying a hemisphere differential principle; a threaded transmission principle of a lead screw is applied by the telescopic mechanism of the robot to realize stretch of the two outer hemispheres; a double-cross four telescopic rod structural design is adopted by the telescopic mechanism of the robot. The double-cross four telescopic rod structural design is adopted by the telescopic mechanism, so that the maximum load capable of being born by the robot is increased during running of the robot, and the stability and the reliability of the internal structure during rolling advance of the robot are improved. The telescopic spherical robot has wide application, and corresponding technical application requirements for carrying out field tasks can be met by arranging different sensors.

Description

technical field [0001] The invention relates to a robot, specifically a spherical robot. Background technique [0002] With the rapid development of modern robot technology, various robots have been put into practical use. Among them, the spherical robot has good dynamic and static balance, will not cause instability due to collisions and falls, and has the characteristics of high maneuverability and flexibility. At present, many spherical robots with different structures have been researched at home and abroad, but the existing spherical robots are all hemispherical and non-retractable, so the application of spherical robots is greatly limited in some special environments and occasions. Contents of the invention [0003] The object of the present invention is to provide a hemispherical differential retractable spherical robot suitable for fields such as entertainment, transportation, detection, fire protection, disaster rescue and space exploration. [0004] The purpose...
