Embodiment Construction

[0026] In order to better illustrate the purpose and advantages of the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Novel sports platform of the present invention such as figure 1 As shown, it includes ball wheel drive system, environment perception system and platform control system. The environmental perception system detects, analyzes and processes the surrounding environment and transmits the environmental information to the platform control system; the platform control system controls the drive motor to drive the ball wheel to roll, so as to realize the movement of the platform.

[0028] In this embodiment, the motion platform based on the omnidirectional drive of the ball wheel is such as figure 2 , image 3 , Figure 4 shown. Among them, the ball-wheel drive system includes three sets of identical ball-wheel drive mechanical structures and three motor ...

Abstract

The invention relates to an intelligent movement platform capable of automatically moving, in particular to a mechanism capable of realizing integral omnidirectional movement of a platform by means of controlling movement of three ball wheels. The intelligent movement platform belongs to the technical field of motor drive, sensor ranging, wireless communication and automatic control, and particularly comprises three identical ball wheel driving mechanical structures, three motor drivers, an environment sensing system and a platform control system. After an ambient environment is detected by the environment sensing system, obtained environment information is transmitted to a platform master control module of the platform master control system, control instructions are obtained after the environment information is processed by the platform master control system and are transmitted to control modules of the motor drivers, the ball wheels are controlled to roll by driving motors, and accordingly the platform moves. The intelligent movement platform is based on an omnidirectional principle of rolling of balls, a manual control working mode and an automatic running working mode can be realized, a single-platform running mode and a multi-platform running mode also can be realized, and the intelligent movement platform has the advantages of small volume, fine balancing, outstanding movement behavior expression, quickness, maneuverability and omnidirectional movement.

Description

technical field [0001] The invention relates to an intelligent motion platform capable of autonomous movement, in particular to a mechanism that realizes the omnidirectional movement of the platform as a whole by controlling the movement of three ball wheels, and belongs to the technologies of motor drive, sensor distance measurement, wireless communication and automatic control field. Background technique [0002] With the progress of society and the development of science and technology, the research on motion platform technology is in the ascendant. While people are paying attention to the multi-purpose of the sports platform in scientific research, they are also studying the development of the sports platform itself, such as the movement form of the sports platform, the intelligence of the sports platform, etc. The Institute of Robotics at Carmackie Mellon University in the United States has developed a robot whose entire robot body stands on a sphere and rubs against t...
