A transforming vehicle, including a main body having at least one of a ground mode, a liquid surface mode, and a flight mode, a plurality of side engines disposed on at least a portion of the main body to steer the main body in response to generating thrust from at least one of the plurality of side engines, a plurality of turbines disposed on at least a portion of a rear of the main body to move the main body in a lateral direction in response to rotation of the plurality of turbines, a plurality of wheel assemblies disposed on at least a portion of a bottom of the main body to facilitate movement of the main body over a ground surface, and a plurality of lifting fans disposed on at least a portion of the bottom of the main body to increase an altitude level of the main body during the flight mode, such that the main body flies.

The propulsion unit including a casing having an inner curved surface and an outer curved surface, at least one tire disposed within the casing within a duct defined by the inner curved surface and the outer curved surface, a first propeller and a second propeller having a plurality of blades extending from within the casing toward a center axis of the casing, and one or more motors housed within the casing, the one or motor being configured to operate the at least one tire, the first propeller, and the second propeller independently of one another. There is also provided a vehicle with one or more propulsion units of the present disclosure.

A convertible ducted fan engine and mounting system. The convertible ducted fan engine has a shroud encircling a mechanical fan. The convertible ducted fan engine includes a fluid-propulsion configuration in which the mechanical fan rotates freely with respect to the shroud to produce thrust through fluid flow, and a drive-wheel configuration in which the shroud rotates about the rotational axis. The mounting system includes at least one gimbal ring and may include a circular track system thereby enabling the convertible engine to be oriented in any direction.

Various embodiments of an amphibious submersible vehicle for use in non-destructive testing of pipe interiors and walls are disclosed herein. In one aspect, the vehicle is operable for amphibious submersible operation such that pipes of various diameters can be inspected under full, partially full, and dry conditions. In another aspect, the vehicle is equipped with a plurality of propellers for travel when fully or partially submerged in water and a plurality of wheels for traveling when in contact with a pipe wall or for traveling over debris. In some embodiments, the vehicle is equipped with a plurality of sensors configured for imaging and navigation which enable the vehicle for pipe inspection and identification of problem areas.

A completely transparent spherical body is surrounded externally by a plurality of leaf plates arranged in equal spacing along a main outer ring rack of the spherical body. Two rubber tires are included to wrap the spherical body. A rider inside the spherical body pedals to rotate the spherical body forward. A vehicle having the spherical body can be autonomously operated to move on land or water, and in the air. In addition, to operate this vehicle, no specific road or environmental requirement is needed, and no other obstacle, even a traffic accident can stop its movement.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements; a fluid pump for pumping liquid manure; a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.

A lightweight vehicle useful for harassing wildlife/waterfowl includes an elongated body/fuselage with a motor-powered propeller in the front and a vertical tail with a controllable rudder in the rear. The vehicle is able to travel over land or water on a pair of elongated floats having a ski-type shape that support the vehicle. The vehicle is made of lightweight materials such as carbon fiber so that it can travel over water, ice, snow, and mown grass without damaging the grass. The vehicle may be remotely controlled or autonomous.

A human-powered wheelchair for use on land and in water that comprises flotation and propulsion means. The wheelchair can be propelled by the operator on land in a manner similar to a typical wheelchair. The wheelchair can be propelled in the water by propellers that are mechanically and rotationally coupled to the side wheels of the wheelchair.
