Abstract: A biomimetic turtle device includes a trunk unit, a limb unit and a control unit. The control unit includes a water depth sensor which detects water depth where the biomimetic turtle device is, and a circuit module which receives the signal from the water depth sensor and determines if the biomimetic turtle device is at a target water depth position, wherein a driving mechanism or a weight adjusting mechanism is operated if the biomimetic turtle device is not at the target water depth position to vary the volume or weight of the trunk unit so as to adjust density of the trunk unit to thereby adjust a water depth position of the biomimetic turtle device.

Abstract: According to the present invention there is provided a method of taking a measurement using a sensor mounted on an aerial vehicle, the aerial vehicle having one or more propellers and one or more motors which are selectively operable to drive the one or more propellers to rotate to cause the vehicle to fly, and a sensor mounted on the aerial vehicle, the method comprising the steps of, operating the one or more motors to drive the one or more propellers to cause the vehicle to fly; at a first time instant, slowing down or turning off said one or more motors; while the one or more motors are slowed down or turned off, taking a measurement using said sensor; at a second time instant, which is after the measurement has been taken using the sensor, operating the one or more motors again to drive the one or more propellers to cause the vehicle to fly. There is further provided a corresponding aerial vehicle.

Abstract: A measuring device, method of measuring, and transport vessel including the measuring device measuring the ground effect region for the vessel in real time and controlling the transport vessel, e.g., a Wing In Ground Effect (WIG) vessel, to remain in ground effect based on those measurements. Distance measurement sensors are distributed about the bottom surface of the vessel and communicating sensor signals with a controller during flight. The controller determines the ground effect region for said WIG in real time from the sensor signals and determines WIG transit elevation.

Abstract: The present invention provides a method for planning a shortest possible three-dimensional path for autonomous flying robots to traverse from one location to the other in a geographical region, including translating a three-dimensional (3D) environment, discretizing the 3D environment into a graph of many grid cells or nodes, employing a modified any-angle path planning algorithm to calculate non-uniform traversal cost of each grid cell and by averaging the total traversal costs along the path to shorten the corresponding computation time, whilst incorporating operational costs other than the traversal cost specific to the autonomous flying robots to be traversed. The shortest possible path found by the present method does not only consider the path length, but also takes different costs of traversing and operating the flying robots into account, which increases its feasibility and flexibility to be applied in a wide variety of situations and technological areas.

Abstract: During a vertical landing state, it is decided whether to switch from the vertical landing state to a self adjusting state. The VTOL vehicle includes the flight controller, the rotor, and a fuselage where the rotor is coupled to the fuselage via a vertical connector. If it is so decided, there is a switch from the vertical landing state to the self adjusting state. During the self adjusting state, a control signal for a rotor is generated where the control signal causes: (1) the rotor to rotate during the self adjusting state and (2) the VTOL vehicle to remain in a fixed position during the self adjusting state, in response to the control signal, and independent of docking infrastructure. During a rotors off state, a rotor off control signal is generated for the rotor that causes the rotor to turn off.

Abstract: A method includes determining, by an unmanned aerial vehicle (UAV), a position of an autoloader device for the UAV; based on the determined position of the autoloader device, causing the UAV to follow a descent trajectory in which the UAV moves from a starting position to a first nudged position in order to deploy a tethered pickup component of the UAV to a payout position on an approach side of the autoloader device; deploying the tethered pickup component of the UAV to the payout position; causing the UAV to follow a side-step trajectory in which the UAV moves laterally to a second nudged position in order to cause the tethered pickup component of the UAV to engage the autoloader device; and retracting the tethered pickup component of the UAV to pick up a payload from the autoloader device.
