Abstract:
A flight system comprising an aircraft equipped with at least four rotors and having a payload, a number of rotors rotating in one direction and a number of rotors rotating in the other direction, as well as a remote control, the aircraft being connected to the remote control, so as to transmit data, via respective transmitter/receiver units, both the aircraft and the remote control having a data processing device connected to the respective transmitter/receiver unit, both the aircraft and the remote control having the same sensors for flight attitude detection, where, when there is an angle change in the remote control around its X- and/or Y- and/or Z-axis, the amount of the angle change correlates with a definable speed of the aircraft, the speed specified according to the angle change being transmitted as a target value of the data processing device of the aircraft and/or of the remote control.
Abstract:
A system for flock-based control of a plurality of unmanned aerial vehicles (UAVs). The system includes UAVs each including a processor executing a local control module and memory accessible by the processor for use by the local control module. The system includes a ground station system with a processor executing a fleet manager module and with memory storing a different flight plan for each of the UAVs. The flight plans are stored on the UAVs, and, during flight operations, each of the local control modules independently controls the corresponding UAV to execute its flight plan without ongoing control from the fleet manager module. The fleet manager module is operable to initiate flight operations by concurrently triggering initiation of the flight plans by the multiple UAVs. Further, the local control modules monitor front and back end communication channels and, when a channel is lost, operate the UAV in a safe mode.
Abstract:
For retrieval of a hovering aircraft, a cable, bar, or similar fixture is suspended in an approximately horizontal orientation across the retrieval area between two well-separated supports. The aircraft slowly flies into this fixture, which then slides along the aircraft in a direction approximately parallel with the aircraft's thrust line. This leads to the aircraft becoming fastened to the fixture by an interceptor or aircraft capturer, which in alternative embodiments are respectively on the aircraft or the fixture or both. Thrust is then reduced, and the aircraft comes to rest hanging from the fixture for subsequent removal. Retrieval is thus accomplished with simple and economical apparatus, light and unobtrusive elements on the aircraft, low risk of damage, and only moderate piloting accuracy.
Abstract:
The drone (10) comprises a drone body (12) and a plurality of propulsion units (16) to drive propellers (18). Removable lateral bumpers (22) extend beyond the area of rotation of the propellers, each bumper being connected to the propulsion units on the same side by connection arms (24) each comprising a pair of elastically deformable elongated blades with at their end a clamp of mounting on a barrel (26) of the motor. Under the effect of an external transverse effort exerted in a median region, the two blades may be deformed in the direction of a mutual moving closer towards a mounting/dismounting position producing, by leverage, an opening of the clamp, so as to secure the bumper arm to the propulsion unit, and conversely the mounting/dismounting of the bumper by detachment of the clamp from the barrel, by the only transverse effort exerted on the connection arms.
Abstract:
In one aspect, a vehicle includes an aerial propulsion system, an altitude sensor system, a water sampling system, and a control system. The water sampling system includes a water sampling extension configured to extend away from the vehicle, one or more water sample receptacles, and a water pump. The control system is configured to perform operations including: guiding, using the aerial propulsion system, the vehicle over a water source; causing, using sensor data from the altitude sensor system, the vehicle to descend towards the water source so that the water sampling extension contacts the water source; and causing, using the water sampling system, the water pump to pump water from the water source into the one or more water sample receptacles through the water sampling extension while the vehicle is in flight over the water source.
Abstract:
Systems, methods, and devices are provided for assisted takeoff of an aerial vehicle. The aerial vehicle may takeoff using a first control scheme and switch to a second control scheme for normal flight when a takeoff threshold is met. The first control scheme optionally does not use integral control while the second control scheme may use integral control. The aerial vehicle may determine that a takeoff threshold is met, based on an output to a motor of the aerial vehicle and/or an acceleration of the aerial vehicle.
