An operating table according to one or more embodiments may include: a table on which to place a patient； a base fixed to a floor； and an articulated robotic arm including a first end supported on the base and a second end supporting the table at a position near the first end in a longitudinal direction of the table. The robotic arm assumes a first posture in which the robotic arm is housed under the table when the table is situated at a first predetermined position. And a length of the robotic arm in the first posture in the longitudinal direction of the table is shorter than or equal to ½ of a length of the table in the longitudinal direction.
