Disclosed are a waist structure of a robot. The waist structure includes: a fixed platform, a connector, a movable platform, a load-carrying bearing and two motors arranged on the fixed platform, and two drive assemblies. The connector includes first and second ends facing away from each other; the first end is provided with a yaw shaft connected to an inner ring of the load-carrying bearing; and the second end is provided with a pitch shaft rotatably connected to the movable platform. Each drive assembly corresponds to one motor, and the drive assemblies are connected to the movable platform and the corresponding motors. The motors can actuate the drive assemblies to drive the movable platform to rotate relative to the connector in an axial direction of the pitch shaft and the connector to rotate relative to the fixed platform in an axial direction of the yaw shaft.
