Abstract

An action robot may include a main body, at least one joint, and at least one limb configured to be rotatably connected to the main body via the joint. The joint may be configured to provide elastic force in a direction in which the limb is unfolded or pulled away from the main body and a wire connected to the limb to pull the limb in a direction in which the limb is folded or pulled toward the main body. The wire may be connected to an elevation rod provided inside the main body. A drive assembly may be provided outside the main body and be configured to lift the elevation rod. A rod spring may be provided and configured to provide a downward elastic force to the elevation rod. A wire support provided within the main body may be configured to support the wire.
