The invention belongs to the technical field of robots, and particularly relates to a robot chassis. A damping unit is arranged below a universal joint, through mutual cooperation of a buffer mechanism, a base, a chassis steering seat and a rotating mechanism, the stability in the vertical direction can be kept all the time, movement of the universal joint in the vertical direction is limited, andit is guaranteed that the chassis cannot be located on the ground due to the fact that the universal joint cannot be kept horizontal. The shock absorption effect on the chassis is achieved, deformation of the chassis is avoided, driving safety of a robot is guaranteed, practicability is high, and reliability is high. In addition, four wheels are driven by double power sources, and a steering mechanism is assisted, so the chassis is flexible in steering and can achieve spot turn. The steering mechanism provided by the invention can realize steering of a driving wheel under coupling drive, thenumber of driving motors is reduced, the cost of the chassis is reduced, and meanwhile, the chassis can perform translational motion and zero-radius steering.

    本发明属于机器人技术领域,具体涉及一种机器人底盘。本发明通过在万向节的下方设置减震单元,通过缓冲机构、基座、底盘转向座和转动机构之间的相互配合,可以始终保持垂直方向的稳定性,限制了万向节垂直方向上的运动,确保底盘不会因万向节保持不住水平而坐落至地面。本发明具有对底盘的减震作用,避免了底盘发生变形,保障了机器人的行车安全,实用性强,可靠性高。此外,本发明采用双动力源驱动四个车轮,辅以转向机构,底盘转向灵活,可以原地转弯。本发明的转向机构可以实现耦合驱动下主动轮的转向;节省了驱动电机的数量,降低了底盘的成本,同时可以使底盘进行平移运动和零半径转向。
