Abstract: A service cart device to transport goods and services which may include a main body member, storage members, top member, attachment member, and computation interface. The device may also include wheel members, one or more of a drive unit, and sensor devices. The storage members may be carried by the main body member. The top member may be positioned above and carried by the main body member. The attachment member may be attached to an upper portion of the top member. The wheel members may be rotatably attached to a lower surface of the main body member. The drive units may selectively rotatably move at one or more of the wheel members. The sensor devices may be configured to detect adjacent objects and surfaces. The sensor devices may emit a detection signal relating to adjacent to object(s) and surface(s) detected. The top member may comprise a buoyant material.
