A functionality utilizing a centrally controlled strategy for continuous communication to specific autonomous vehicles, or drones, that are designed for extreme conditions and assigned specific missions with the ability to be replaced during the mission. This functionality is an improvement on existing swarm and leader-follower tactics as it retains control of the drones at a central command center, allowing the drones to both receive individual commands from the hub but also operate independently of it with direct pilot control. This direct communication allows for real time process of ordered substitution to replace any drone during the mission.

An unmanned aerial vehicle (UAV) for transporting items between locations includes a frame and a propulsion system coupled to the frame, the propulsion system including at least one transmission and at least one motor. The UAV also includes a load support area of the frame, the load support area comprising at least one of a different material than the frame or structural supports.

The invention pertains to the development of a unique and small transformable robot that will fit into very small pipes, openings, or packing tubes, thereby enabling complex missions and also which can fly and drive. Other advantages of the system include portability, weight, perch, and stare capabilities. The present invention comprises a compact transformable robot capable of flying and driving designed to furl or fit into small openings, containers, packing tubes, or pipes containing a thrust, a main body, controls, and rotating propellers. The compact transformable robot capable of flying and driving that is designed to furl or fit into small openings, containers, or pipes comprises a ground locomotion, an aerial locomotion, controls, sensors, and a radio.

An unmanned aerial vehicle (UAV) includes a casing including a first end portion and a second end portion away from the first end portion. An accommodation chamber is formed at the second end portion. The UAV further includes a support plate arranged in the casing. The accommodation chamber is recessed relative to the support plate. The UAV also includes a circuit board assembly housed in the casing and a load provided at the first end portion of the casing. The circuit board assembly includes a circuit board connected to the support plate and an inertial measurement assembly provided at the circuit board and accommodated in the accommodation chamber.

Systems and methods are provided for autonomous robotic surgery which is preferably integrated with autonomous-assisted intraoperative real-time single modality and/or multi-modality fusion imaging/electrophysiological diagnostics. The robotic surgery systems and methods can be integrated with autonomous-assisted intraoperative body/limb positioning, and integrated with autonomous-assisted land and unmanned aerial vehicular patient transportation.

A line-replaceable thrust module includes a nacelle configured to be mechanically connected to an anchoring location of an unmanned aerial vehicle (UAV), an electric motor coupled to the nacelle, an electric speed controller configured to control the speed of the electric motor and configured to be electrically connected to a communication network of the UAV, and a fuel cell system configured to produce electrical energy from an electrochemical reaction between hydrogen and oxygen. The fuel cell system includes a fuel cell, a hydrogen tank, a pressure regulator coupled to the hydrogen tank, and a supply line coupled between the pressure regulator and the fuel cell.

An aircraft has a propulsion unit and a fuselage unit. The propulsion unit has a first rotor for providing a propulsion force on the aircraft. The fuselage unit extends along a rotation axis of the first rotor and has a rotationally symmetrical shape with respect to the rotation axis of the first rotor. The fuselage unit has a suspension at a first end by which the fuselage unit is coupled to the first rotor so that the fuselage unit is spaced apart from the first rotor along the rotation axis. A detection unit for the detection of environmental information is provided in the area of a second end of the fuselage unit. The propulsion unit is designed to keep the aircraft in a hovering flight condition so that a relative position of the aircraft with respect to a reference point on the Earth's surface remains unchanged.

A drone includes a fuselage and a plurality of housing structures for a plurality of engine units. The mechanical connection between each engine unit and each housing structure for the engine unit has: a ball joint arranged in the axis of rotation of the engine unit, opposite the rotor; and a flexible connecting member connecting the engine unit to the housing structure for the engine unit.

Systems, methods, and devices for propelling self-propelled movable objects are provided. In one aspect, a rotor assembly for a self-propelled movable object comprises: a hub comprising a first fastening feature; a drive shaft comprising a second fastening feature and directly coupled to the hub by a mating connection of the first and second fastening features, wherein the drive shaft is configured to cause rotation of the hub such that the mating connection of the first and second fastening features is tightened by the rotation; and a plurality of rotor blades coupled to the hub and configured to rotate therewith to generate a propulsive force.
