Eristalis tenax, the common drone fly, is a common, migratory, cosmopolitan species of hover fly. [2] It is the most widely distributed syrphid species in the world, and is known from all regions except the Antarctic. It has been introduced into North America and is widely established. It can be found in gardens and fields in Europe [3] and ...
Eristalinus taeniops can reach a length of 11–14 millimetres (0.43–0.55 in). [5] These hoverflies exhibit a bee-like yellow and black coloration (Batesian mimicry) and are often mistaken for wasps or bees.
Several species are known as drone flies (or droneflies) because they bear a resemblance to honeybee drones. Drone flies and their relatives are fairly common generalist pollinators , [ 2 ] the larvae of which are aquatic, and breathe through a long, snorkel -like appendage, hence the common name rat-tailed maggots .
Drone swarms are used in target search, drone displays, and delivery. A drone display commonly uses multiple, lighted drones at night for an artistic display or advertising. A delivery drone swarm can carry multiple packages to a single destination at a time and overcome a single drone's payload and battery limitations. [11]
The Netra is a lightweight UAV, manufactured by carbon fiber composites, that uses quadcopters to provide lift and control giving a VTOL capability. It has no moving parts other than the rotors, motors and transmissions, and hence it requires very low maintenance.
Drone racer wearing FPV goggles and holding a radio controller. First-person view (FPV), also known as remote-person view (RPV), or video piloting, is a method used to control a radio-controlled vehicle from the driver or pilot's viewpoint.
OpenDroneMap is an open source photogrammetry toolkit to process aerial imagery (usually from a drone) into maps and 3D models. [3] [4] [5] The software is hosted and distributed freely on GitHub. [6] OpenDroneMap has been integrated within American Red Cross's in-field Portable OpenStreetMap system. [7]
Unlike unmanned combat aerial vehicle (UCAV), this type of system is not designed to carry aircraft ordnance such as missiles, ATGMs, or bombs for drone strikes. The main purpose is to provide battlefield intelligence. [2] [3] Small sized short-range man-portable unmanned aerial vehicles are called miniature UAV also used for battlefield ...
