The invention generally relates to the measurement and predictions of conditions and contaminants; chemical, particulate and gaseous in and around water impoundments. More specifically, the invention relates to the use of an autonomous watercraft to analyze the chemical and physical properties of a body of water, such as a pond holding water used in a hydraulic fracturing operation.

The modular autonomous air and road mobility (AARM) vehicle with Vertical Take-off and Landing (VTOL) capability provides combined air and road mobility solution.

AARM is clean energy powered, modular vehicle, which can be undocked and redocked into road module and air module, providing uninterrupted autonomous mobility between air and road. In addition, the modular design enables: Easy navigation through highly populated areas without the need to accommodate fixed wing aircraft on urban roads. Reduced energy consumption and noise levels in urban roads by not having to carry the air propulsion system into urban areas.

The road and air modules dock with each other through a sensor guided docking and load carrying mechanism (SGDMS), allowing connectivity, command and control. The vehicle can be scaled appropriately to serve: personal mobility, shared car, air taxis, regional air transport, cargo and shipping, defense missions, medical evacuations and air ambulances.

A fixed-wing aerial underwater vehicle includes a shell component, a flight component and a pneumatic buoyancy component. The flight component includes a fixed wing and rotors, and the fixed wing and the rotors are mounted in the shell component. The pneumatic buoyancy component includes an air bladder and an inflation and deflation portion, and the inflation and deflation portion can inflate and deflate the air bladder. The air bladder is installed on the shell component, a containing space is formed in the shell component, and the inflation and deflation portion is partially or entirely installed in the containing space. Each rotor includes a rotor supporting rod, a motor base, a motor and a propeller, which are sequentially connected. A control method for the fixed-wing aerial underwater vehicle mentioned above is further provided.

A mobility vehicle transfer platform includes an elevation passage provided in a structure provided with a take-off and landing site for an air mobility vehicle and having an internal space extending in the vertical direction to be connected to the take-off and landing site and to allow a ground mobility vehicle to be elevated or lowered through the internal space to be connected to or separated from the air mobility vehicle, and an elevation unit provided in the internal space of the elevation passage, having an elevation portion selectively connected to the ground mobility vehicle and configured for elevating or lowering the ground mobility vehicle in the elevation passage when the ground mobility vehicle is connected to the elevation portion.

Provided is an air-ground use vehicle capable of opening and closing a door, while a main wing is folded along a fuselage, without interfering with the main wing. The air-ground use vehicle includes: a main wing; a fuselage; a sliding door provided in a side surface of the fuselage; and a hinge mechanism that connects the main wing to the fuselage and that is capable of rotating between a first state, in which the main wing 4 is folded along the fuselage, and a second state, in which the main wing is opened to a side of the fuselage. In the first state, the sliding door opens and closes by sliding in a space formed between the main wing and the fuselage, with an outer surface of the fuselage and an inner surface of the sliding door facing each other.
