Chassis and robot

The utility model relates to the technical field of mobile robots, in particular to a chassis and a robot, the chassis comprises a vehicle frame and a damping assembly connected with the vehicle frame, the damping assembly comprises a positioning plate, at least two supporting plates, supporting columns and damping balls, the positioning plate is connected with the vehicle frame, and the supporting columns are arranged on the supporting plates. The two supporting plates are correspondingly arranged in parallel relative to the two sides of the positioning plate and are fixed through the supporting columns, the damping balls are arranged between the supporting plates and the positioning plate, that is, the positioning plate, the supporting plates and the damping balls form a stacked structure, and then the stacked structure is fixed through the supporting columns to serve as a damping structure, so that the structure is simpler; the damping ball can be prevented from being separated from the positioning plate d
