Abstract: The technical description relates to perimeters for vehicles. Specific examples relate to vehicle perimeters established by unmanned aerial vehicles (UAVs), such as autonomous drones, for a variety of vehicle types, including manually-driven, partially autonomous, and fully autonomous vehicles. Perimeter devices, vehicles, including autonomous vehicles and human-controlled vehicles, UAVs, and related systems and methods are described. Perimeter devices respond to triggering events, such as vehicle-immobilizing events, GPS-based events, and environment-based events, to establish a perimeter adjacent a vehicle such that observers can visually detect the presence of a signal member, such as a warning triangle having a reflective surface. An example vehicle includes a tractor unit, a trailer connected to the tractor unit, a storage enclosure associated with the tractor unit, and a plurality of perimeter devices disposed in the chamber. Each perimeter device of the plurality of perimeter devices includes a triangular signal member, a base member, and a UAV. Each perimeter device is adapted to deploy from the chamber and establish a perimeter by the vehicle in response to a triggering event, such as parking of the vehicle in a location for which a perimeter must be established, impact of the vehicle with another object, such as during a traffic accident, rollover of the vehicle, or mechanical and/or electrical failure of the vehicle.

Abstract: Provided herein are systems and methods for an unmanned aerial vehicle (UAV) to skid and roll along an environmental surface. A reliable UAV includes an airframe assembly, a propulsion system, and a logic device configured to communicate with the propulsion system. The airframe assembly includes a cylindrical rolling guard configured to allow the UAV to roll along an environmental surface in contact with the cylindrical rolling guard. The logic device is configured to determine a rolling orientation for the UAV corresponding to the environmental surface, maneuver the UAV to place the cylindrical rolling guard of the airframe assembly in contact with the environmental surface, and roll the airframe assembly of the UAV along the environmental surface at approximately the determined rolling orientation while the cylindrical rolling guard is in contact with the environmental surface.

Abstract: A method of making-up tubular string components can include inputting to an image processor image data output from at least one camera (28), the image processor in response detecting positions of a tubular (14) and a mark (30) on another tubular (20), threading the tubulars with each other while inputting position data from the image processor to a controller, and the controller terminating the threading in response to the position of the mark relative to the position of the first tubular being within a predetermined range. Another method of making-up tubular string components can include, in response to inputting image data to an image processor, the image processor detecting longitudinal positions of two tubulars, threading the tubulars with each other, and a controller terminating the threading in response to the longitudinal position of one tubular relative to the longitudinal position of the other tubular being within a predetermined range.

Abstract: In some examples, an unmanned aerial vehicle (UAV) employs one or more image sensors to capture images of a scan target and may use distance information from the images for determining respective locations in three-dimensional (3D) space of a plurality of points of a 3D model representative of a surface of the scan target. The UAV may compare a first image with a second image to determine a difference between a current frame of reference position for the UAV and an estimate of an actual frame of reference position for the UAV. Further, based at least on the difference, the UAV may determine, while the UAV is in flight, an update to the 3D model including at least one of an updated location of at least one point in the 3D model, or a location of a new point in the 3D model.

Abstract: A crossbar assembly (30a, 30b) for facilitating isolation of a sensor assembly from vibration comprises an outer crossbar segment (60), an inner crossbar segment (72), and an isolator (38a, 38b). The inner crossbar segment (72) comprises a payload mount interface (36a, 36b) and an inner isolator interface operable to mount to an isolator (38a, 38b). The outer crossbar segment (60) comprises a structure interface (34a, 34b) and an outer isolator interface (61) operable to mount to the isolator (38a, 38b). The isolator (38a, 38b) can be supported by the outer and inner crossbar segments(60, 72). The isolator (38a, 38b) comprises a first wire rope assembly (50) comprising wire ropes (52) extending longitudinally from the outer crossbar segment (60) to the inner crossbar segment (72), and a second wire rope assembly (54) comprising a wire rope (56) extending circumferentially between the outer and inner crossbar segments (60, 72). The isolator (38a, 38b) operates to partially decouple the outer crossbar segment (60) from the inner crossbar segment (72) and dampen vibrations propagating between the outer and inner crossbar segments (60, 72).
