Abstract
A tray assembly is provided. The tray assembly includes a first tray configured to be mounted to a robot; and a second tray provided above the first tray and configured to be rotatably coupled to the first tray. The second tray includes at least one first rolling member provided on a lower surface of the second tray, which faces the first tray, and an elastic member having at least one end which is fixedly connected to the lower surface. When the second tray is rotated relative to the first tray, the second tray is configured to be returned to its original position by virtue of a restoring force of the elastic member of the second tray.
