A method of moving liquid manure in a liquid manure lagoon involves: driving an amphibious vehicle into the liquid manure lagoon by remotely controlling speed and direction of the amphibious vehicle on the ground, the amphibious vehicle having a ground-engaging propulsion structure for driving the amphibious vehicle on the ground and a floatable vehicle body to float the amphibious vehicle in the liquid manure lagoon; and, moving the liquid manure in the liquid manure lagoon by remotely controlling speed and direction of the amphibious vehicle in the liquid manure lagoon.

There is provided an amphibious vehicle for use on land and water comprising lateral floaters which increases the stability of the vehicle when in water. While on land, the lateral floaters may be retracted within the body of the vehicle to reduce the width of the vehicle.

A UAV with vertical takeoff and landing (VTOL) function. having a plurality of lift propellers; a cabin engaged with a plurality of lift propellers; a water propulsion system engaged with the cabin to push the cabin in a forward direction when the cabin is at least partially immersed in water; at least one water inlet engaged with the water propulsion system; the cabin is a cargo hold or a passenger cabin. The UAV provided by the disclosure can realize vertical takeoff and landing in the water area, and fly, drive and navigate freely in the whole area.

An amphibious vehicle for operation in a liquid manure lagoon has a first liquid manure mover (e.g., a propeller or a nozzle) that is vertically adjustable through a closed-loop linkage assembly to change the vertical position of the first liquid manure mover with respect to the surface of the liquid manure lagoon. The vehicle has a second liquid manure mover (e.g., a propeller or a nozzle) that is angularly adjustable to adjust the orientation of the second liquid manure mover with respect to the surface of the liquid manure lagoon.

A combination of a marsh buggy is coupled with a modified skid steer. The skid steer has a frame, and hydraulic lines for attaching to hydraulic driven motors for driving a track or wheeled drive system. The skid steer further having an engine and a hydraulic system, including a pump and hydraulic tank, and valves; an operator's cab positioned on the frame, said operator's cab further comprising a set of hydraulic controls connectable to the hydraulic system for controlling the drive system and a hydraulically driven lift system, including two booms, each boom comprising a first arm and a second arm, the first arm being pivotably mounted to the frame, the second arm being telescopically coupled to the first arm by a hydraulic cylinder controllable from the operator's cab. The marsh buggy includes a first and a second floatable pontoons, the two pontoons coupled together in a parallel but offset relationship. Each pontoon has an endless track including a chain and treads coupled around the periphery of each respective pontoon, and a series of sprockets coupled to the chain on each pontoon; each sprocket connected to a hydraulic motor. The marsh buggy further has hydraulic motors and drive sprockets coupled to the hydraulic system for driving the endless track. The skid steer is mounted on the marsh buggy, between the two pontoons, and the hydraulic motors of the marsh buggy are operationally coupled to said hydraulic system of said skid steer so that said hydraulic controls in said cab are operationally connected to said hydraulic motors to control the drive system on the marsh buggy.

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.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and 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.
