Abstract: An automated gas supply system includes a gas cylinder transfer unit configured to transfer a cradle in which one or more gas cylinders storing a gas therein are stored; a gas cylinder inspection unit configured to check properties of the gas stored in the gas cylinder transferred from the gas cylinder transfer unit and check whether the gas leaks from the gas cylinder; a storage queue configured to receive the gas cylinder from the gas cylinder inspection unit by a mobile robot and configured to classify and store the transferred gas cylinders according to the properties of the gas stored in the gas cylinder; and a gas cabinet configured to receive the gas cylinder from the storage queue by the mobile robot and fasten a gas pipe, which is connected to a semiconductor manufacturing process line, to a gas spray nozzle, which is disposed at one side of the received gas cylinder, to supply the gas stored in the gas cylinder to the semiconductor manufacturing process line, wherein the gas cabinet includes a residual gas detector configured to detect a residual amount of the gas stored in the gas cylinder fastened to the gas pipe, and when the residual amount of the gas detected by the residual gas detector is less than or equal to a set residual amount of gas, the mobile robot recovers the gas cylinder from inside the gas cabinet and transfers a gas cylinder stored in the storage queue to the gas cabinet.

Abstract: A caster apparatus is provided. In one embodiment, there is provided a caster apparatus including a caster wheel and a first driving wheel disposed on a first side of the caster wheel. The first driving wheel is configured to be driven by a first motor. A second driving wheel is disposed on a second side opposite to the first side of the caster wheel. The second driving wheel is configured to be driven by a second motor different from the first motor. A first actuator is configured to move the first driving wheel in a vertical direction to a ground according to a curvature of the ground. A second actuator is configured to move the second driving wheel in a vertical direction to the ground according to a curvature of the ground, wherein the first and second driving wheels are configured to steer the caster wheel.
