The invention relates to the technical field of robots, and provides a ball wheel assembly, a chassis and a robot. The ball wheel assembly comprises a mounting frame, a ball wheel, a friction roller set and a driving part. A mounting space is formed in the mounting frame; the ball wheel is mounted on the mounting frame and partially extends out of the mounting space; the friction roller combination is embraced on the ball wheel; the driving piece is connected to the mounting frame and is in power coupling with the friction roller set so as to drive the friction roller set to roll. According to the ball wheel assembly disclosed by the embodiment of the invention, the friction roller group is in contact with the ball wheel in a surrounding manner, so that enough friction force is provided for the ball wheel, stable rotation of the ball wheel is ensured, and the movement stability of the ball wheel assembly is improved. And meanwhile, by means of the mode that the friction roller set is arranged on the ball wheel in a surrounding mode, arrangement of the driving piece, the friction roller set and the ball wheel is more compact, and space occupied by the ball wheel assembly is greatly reduced.
本发明涉及机器人技术领域,提供一种球轮组件、底盘和机器人。根据本发明的球轮组件,包括安装架、球轮、摩擦辊组和驱动件。安装架内部形成有安装空间;球轮安装于安装架,球轮部分伸出安装空间;摩擦辊组合抱于球轮;驱动件连接于安装架,驱动件动力耦合于摩擦辊组,以使驱动摩擦辊组滚动。根据本发明实施例的球轮组件,摩擦辊组通过合抱的方式和球轮接触,为球轮提供了足够的摩擦力,保证了球轮的稳定转动,从而提高了球轮组件的运动稳定性。同时摩擦辊组合抱于球轮的方式,使得驱动件、摩擦辊组和球轮之间的排布更加紧凑,大大减少了球轮组件对空间占用。
