A robot cleaner capable of returning to an external recharging device. The robot cleaner includes a driving portion for driving a plurality of wheels, at least one camera installed on a body of the robot cleaner, the camera for photographing external surroundings, and a controller for photographing an image through a camera for recognition of a connection position where the external recharging device is connected with the robot cleaner and stores the photographed image, and controls the driving portion so that the robot cleaner can move from the external recharging device to a destination when an operation start signal is received in the robot cleaner connected to the external recharging device, and for tracing a path to the connection position of the external recharging device and the robot cleaner during a robot cleaner's return to the external recharging device while comparing a current image currently taken by the camera with a stored image of the connection position of the robot cleaner and the external recharging device. Returning of the robot cleaner is carried out when the robot cleaner, separated from the external recharging device, completes its job or needs a recharging, by using the previously stored image and an image currently taken by the camera. Accordingly, an error in the location process, mainly caused due to external interference signals, is decreased, and errors in tracing a path and connecting to the external recharging device can also be decreased.

A jack up work platform is recited. The work platform comprises a hovercraft vessel outfitted with several jack up legs. The hovercraft can traverse environmentally sensitive terrain such a brackish and freshwater marshes without the need to dig canals that may cause or exacerbate salt water intrusion. Once the drilling or exploration site is reached, the jack up legs may be lowered, lifting the work platform above the surface. Once the vessel is secured on the legs, it may be used like a conventional oil field work platform for drilling, exploration, or construction jobs for which other work platforms or vessels are typically used. The deck of the hovercraft may serve as the work platform or the deck may be provided with a cantilevered work platform extension. The hovercraft will preferably be provided with typical oil field heavy machinery such as a crane for assembly of the legs, and drill stem as well as for work on other structures.

A transportation system uses a carrier conduit in the form of a long tube or channel in order to drive a vehicle by air pressure. A carrier having end plates obstructs the travel of air through the carrier conduit. Pressure differentials formed within the carrier conduit serve to propel the carrier through the carrier conduit. By rollably supporting the carrier within the carrier conduit, friction is reduced between the carrier conduit and the carrier. The carrier may be magnetically coupled to a vehicle having vanes and a set of track- or rail-engaging wheel assemblies on vanes. The vanes may pivot upon the vehicle and serve to allow the vehicle to rollably or slidably couple to the carrier conduit track. The motion of the carrier serves to propel the vehicle along the carrier conduit track as the vehicle is magnetically coupled to the carrier. Composite materials used to construct the carrier conduit may allow for such magnetic coupling without the interference that might occur through the use of ferromagnetic materials or the like. The carrier conduit may be mounted upon pillars or pylons and sources of pressure may either be present at either end of the carrier conduit, distributed at propitious points there along, or incorporated into the carrier.

The landing gear units are coupled to the fuselage and are arranged in at least two discrete columns and at least ten discrete rows. The central storage cavity and the wing storage cavities are configured to receive cargo including intermodal re-usable cargo containers.

A recharging system for a rechargeable battery (281) of an inverted pendulum type vehicle (1) comprises a stand (86) for holding the vehicle in a substantially upright posture by using a supporting member (91, 96) that engages a prescribed part of the vehicle, a power feed device (95, 152) is provided on the stand, and a power take device (88, 151) provided on the vehicle. The power take device is positioned so as to couple with the power feed device when the prescribed part of the vehicle is engaged by the supporting member of the stand. The stand allows the vehicle to be placed in an upright posture simply leaning the vehicle against a part of the supporting member, and the electric connection between the rechargeable battery of the vehicle and the power source can be established at the same time without requiring any extra effort.

A magnetic adhesive and braking system for a remote controlled vehicle adapted for traversing across ferromagnetic surfaces of a steel shipping container including the vertical walls and ceiling. The magnetic wheel system allows the vehicle to traverse vertical grades. The magnetic braking system both securely holds the vehicle when stopped on a vertical surface, and exerts enough attractive force between the vehicle and the shipping container to allow a vehicle mounted drill to operate. The magnetic brake design uses mechanical advantage such that the force required to roll the vehicle vertically downward is heightened to the force required to detach the vehicle in a perpendicular vector from the container's surface.

An improved VTOL aircraft or flying car mechanism that utilizes counter-rotating blades (18) spinning inside a duct (14) causing varying speeds and volumes of atmosphere to pass across an exposed plurality of wing shaped lift generating airfoils, referred to as sucked flaps (36), at an opening in that duct (70). The volumes of atmosphere will then pass through to a lift amplifying, turbulence reducing, radial, spiral airflow generator (68) and then into thrust vector airfoils (26), which will then pass through the duct (70) again as it forms a circular path (72) back to the sucked flaps (36), where it is then re-circulated. The air pressure flowing over the top of the airfoils is reduced relative to the air pressure below the airfoils causing relatively large amounts of lift to be generated to overcome the force of gravity. Because the entire wing surface area necessary to lift the flying car or aircraft can now fit within the confines of the length, width, and height of a standard freeway-capable motor VTOL aircraft or flying car, there is no need for foldable wings, foldable control surfaces, exposed rotors, exterior wind blasts or other problems associated with prior art helicopters, flying cars, or other VTOL aircraft.

Self-leveling legs are used to accommodate landing a ducted fan hovercraft on a sloped surface such as a roof-top. These legs move to accommodate a variation of slope within their range of motion irrespective to the azimuth of the vehicle body. The configuration and operation of the landing legs allow the hovercraft to land in a stable fashion with the hovercraft vehicle body maintained in a vertical orientation. The basic kinematics of the present invention is the displacement of one landing leg upwards is connected by a horizontal member to the opposite leg and displaces it downwards, and visa-versa. Planar surface contact is accomplished by the unique curvature of the legs and the splay of the legs from the vehicle body.

Movement of the pallet between the stage and the transporting receptacle is performed by levitating a support frame of the carrying vehicle on which the pallet has been positioned using a controllable discharge of gas exiting from exhaust nozzles of the carrying vehicle.
