Abstract: Provided is a movable robot. The movable robot includes a main body provided with a traveling part; at least one through-hole defined in a top surface of the main body, at least one module guide configured to guide an installation position of a service disposed above the main body, and guide supporter rotatably supporting the module guide inside main body. The module guide may rotate between a first position within the main body and a position protruding upward from the main body through the through-hole.

Abstract: A robot may include a main body coupled to a traveling unit, a display unit disposed above a front portion of the main body, and a battery incorporated in the main body. The traveling unit may include a wheel having a rotational axis extending in a first direction, and the battery may overlap a vertical plane that extends along the rotational axis. The vertical plane and a center of the battery may be separated by a prescribed distance in a second direction that is orthogonal to the first direction.

Abstract: A modular movable robot includes a lower plate provided with a traveling unit, an upper plate spaced above the lower plate, a plurality of lower supporting frames vertically elongated between the lower plate and the upper plate, a top plate spaced above the upper plate, a plurality of upper supporting frames vertically elongated between the upper plate and the top plate, and a housing surrounding edges of the lower plate, the upper plate, and the top plate. A longitudinal length of the housing is longer than a horizontal width of the housing.
