The invention belongs to the field of robot automatic control, and particularly relates to a robot chassis with an adjustable gravity center. The robot chassis comprises universal wheels, a chassis fixed platform, sliding rails, a chassis movable platform and a linear electric cylinder, the bottom of the chassis fixed platform is provided with the universal wheels for achieving movement and steering of the robot chassis, and the top of the chassis fixed platform is provided with the sliding rails; the chassis movable platform is positioned above the chassis fixed platform, is assembled and fixed with the upper body of a robot, and is in sliding connection with the sliding rails; and the two ends of the linear electric cylinder are hinged to the chassis fixed platform and the chassis movable platform respectively, the chassis movable platform is driven to slide front and back along the sliding rails on the chassis fixed platform through extension or shortening of the linear electric cylinder, and gravity center of the robot chassis is adjusted. When the gravity center of the robot is changed through the linear electric cylinder, balance weight does not need to be added, the robot structure does not need to be changed, and secondary development design cost and transformation cost can be saved.
本发明属于机器人自动控制领域,具体地说是一种重心可调式机器人底盘,包括万向轮、底盘定平台、滑轨、底盘动平台及直线电缸,其中底盘定平台的底部安装有实现机器人底盘运动及转向的万向轮,所述底盘定平台的顶部安装有滑轨;所述底盘动平台位于底盘定平台的上方,与机器人上身装配固定,该底盘动平台与所述滑轨滑动连接;所述直线电缸的两端分别与底盘定平台及底盘动平台铰接,通过该直线电缸的伸长或缩短,驱动所述底盘动平台沿底盘定平台上的滑轨前后滑动,实现机器人底盘的重心调节。本发明通过直线电缸改变机器人重心时,无需增加配重,无需改变机器人结构,可节约二次开发设计成本与改造成本。
