Abstract: In some embodiments, an unmanned aerial vehicle (UAV) is provided. The UAV comprises one or more processors; a camera; one or more propulsion devices; and a computer-readable medium having instructions stored thereon that, in response to execution by the one or more processors, cause the UAV to perform actions comprising: receiving at least one image captured by the camera; generating labels for pixels of the at least one image by providing the at least one image as input to a machine learning model; identifying one or more landing spaces in the at least one image based on the labels; determining a relative position of the UAV with respect to the one or more landing spaces; and transmitting signals to the one or more propulsion devices based on the relative position of the UAV with respect to the one or more landing spaces.

Abstract: An on-board navigation system for an unmanned aircraft system (UAS) operating in an unknown environment. A point-cloud sensor system generates point cloud data representing the unknown environment. An on-board processing system processes the point cloud data to generate both a 2-D occupancy grid and a 3-D voxel map, with the 2-D occupancy grid having cells with known (seen) and unknown data. Additional processing determines an amount of known-to-unknown (transitional) data in each cell, thereby determining unexplored regions. A cost is assigned to each unexplored region, based at least in part on the amount of transitional data in cells of the region. The unexplored regions are then sorted based on their costs, thereby determining an optimal region to explore. The 3-D voxel map is used to find a safe area within the optimal region where the UAS may fly. A flight path to the optimal region is then calculated.

Abstract: A system (100) for determination of flight performance of the bioinspired flapping-wing aerial vehicle (101) in simulated space conditions discloses the aerial vehicle (101) installed in a thermo-vacuum chamber (103) that maintains vacuum and temperature for aerial vehicle (101) to simulate climatic conditions in space, where the aerial vehicle (101) is evaluated by the force transducer (104) and data acquisition system (105) acquires the data from force transducer (104). The flapping motion of the wing (101b) of the aerial vehicle (101) in space conditions increases the velocity of aerial vehicle (101), where dynamic wing twisting maintains the wing (101b) at a specific angle of attack to generate lift force and wing deformation occurs during which the passive pitch angle produces high lift forces, facilitating stable flight in simulated space conditions.

Abstract: A convertible robot including a plurality of modules connected one to another by one of a plurality of joints, wherein the plurality of modules has a first end and a second end that is adapted to allow for removable attachment to the first end. The convertible robot also includes a coupling that reversibly converts the plurality of modules between one configuration and at least one other configuration. One configuration is a snake-arm configuration in which the plurality of modules are in an elongated arrangement. Another configuration is a drone configuration in which the first and second ends of the plurality of modules are attached and in a loop-shaped arrangement.

Abstract: Systems, computer readable medium and methods for fully autonomous drone flight are disclosed. Example methods include taking off, navigating in accordance with a flight plan, and navigating the autonomous drone to land. The autonomous drone performs flight plans with only an initial command for the autonomous drone to fly and, in some examples, an indication of a landing space such as an open hand presented under the autonomous drone. After an initial fly command, the autonomous drone is not controlled by a remote-control device and does not receive any additional commands to complete the flight plan. The autonomous drone enters a lower energy state while flying where the wireless connections are turned off since the autonomous drone does not respond to commands during flight.

Abstract: Implementations are directed to generating a stream of agricultural annotations with respect to area(s) of interest of an agricultural field, and providing the stream of agricultural annotations for presentation to the user in an augmented reality manner with respect to the area(s) of interest. In some implementations, a stream of vision data may be received at a first computing device of the user and from a second computing device of the user. Further, the first computing device may process the stream of vision data to generate the stream of agricultural annotations. Moreover, the first computing device may transmit the stream of agricultural annotations to the second computing device to cause the stream of agricultural annotations to be provided for presentation to the user. In other implementations, the first computing device may be omitted, and the second computing device may be utilized to generate the stream of agricultural annotations.

Abstract: A computer-implemented method comprises receiving an image captured by a camera on an unmanned aerial vehicle (UAV). The image depicts an environment below the UAV. A feature mask associated with the image is generated via a machine learning model that is trained to identify and semantically label pixels representing the environment depicted in the image. One or more reference tiles associated with the environment are retrieved. The reference tiles are associated with particular geographic locations and specify semantically labeled pixels representing the geographic locations. The semantically labeled pixels of the feature mask are correlated with the semantically labeled pixels of at least one of the one or more reference tiles to determine the geographic location of the UAV in the environment.

Abstract: A computer-implemented method comprises receiving, by an image processing system, a depth image captured by a stereo camera on an unmanned aerial vehicle (UAV). One or more pixels of the depth image are associated with corresponding depth values indicative of distances of one or more objects to the stereo camera. The image processing system determines that one or more pixels of the depth image are associated with invalid depth values. The image processing system infers, based on a distribution of the one or more pixels of the depth image that are associated with invalid depth values, a presence of a potential obstacle in an environment of the UAV. The UAV is controlled based on the inferred presence of the potential obstacle.

Abstract: A method includes navigating, by an unmanned aerial vehicle (UAV), to a first altitude above a first delivery point at a delivery location. The method further includes determining, by the UAV, a second delivery point at the delivery location. The method includes navigating, by the UAV, through a descending trajectory to move the UAV from the first altitude above the first delivery point to a second altitude above the second delivery point at the delivery location. The second altitude is lower than the first altitude. The method additionally includes delivering, by the UAV, a payload to the second delivery point at the delivery location. The method includes after delivering the payload, navigating, by the UAV, through an ascending trajectory to move the UAV from a third altitude above the second delivery point to a fourth altitude above the first delivery point. The fourth altitude is higher than the third altitude.
