AeroVironment Nano Hummingbird
A flapping-wing micro drone designed for urban reconnaissance.
The AeroVironment Nano Hummingbird, also known as the Nano Air Vehicle (NAV), is a tiny remote-controlled aircraft designed to resemble and fly like a hummingbird. Developed in the United States by AeroVironment, Inc. for the Defense Advanced Research Projects Agency (DARPA), it is notable for its flapping-wing propulsion and ability to hover, fly in multiple directions, and enter indoor environments for surveillance.

Lore & Background
The Nano Hummingbird was developed under DARPA's Nano Air Vehicle (NAV) program, which contributed $4 million to AeroVironment since 2006 to create a prototype hummingbird-like aircraft. The finished prototype, announced to the public on 17 February 2011, met all of DARPA's flight test milestones and exceeded some objectives. The aircraft uses its flapping wings for both propulsion and attitude control, allowing it to climb and descend vertically, fly sideways, forward, backward, rotate clockwise and counter-clockwise, and hover in mid-air.
The vehicle has a body shaped like a real hummingbird, with a wingspan of 6.3 inches and a total flying weight of 0.67 ounces—less than an AA battery. This weight includes batteries, motors, communications systems, and a small video camera payload. It can fly outdoors or enter a doorway to investigate indoor environments, and might perch on windowsills or power lines to observe its surroundings, relaying camera views back to its operator.
While the device is bigger and heavier than a typical real hummingbird, it is smaller and lighter than the largest hummingbird varieties. DARPA stated that the Nano Air Vehicle's configuration would 'provide the warfighter with unprecedented capability for urban mission operations.'
Reader's Guide
The Nano Hummingbird represents a significant step in miniaturized aerial surveillance, demonstrating that a flapping-wing aircraft can carry a video camera payload and perform precise maneuvers in confined spaces. Its ability to hover, fly through doorways, and perch on structures gave it a unique role for reconnaissance in urban environments or on battlefields. By meeting and exceeding DARPA's technical goals, the prototype validated the concept of a biomimetic nano air vehicle for military use. The program's $4 million investment since 2006 produced a craft that could relay real-time video from locations inaccessible to larger drones, such as inside buildings. Although the Nano Hummingbird itself remained a prototype, its development influenced subsequent research into flapping-wing micro air vehicles and highlighted the potential for covert, close-quarters surveillance. The aircraft's public announcement in February 2011 showcased a new class of unmanned systems that combined biological mimicry with practical reconnaissance capabilities.

Frequently Asked Questions
What is the AeroVironment Nano Hummingbird?
It is a palm-sized, remote-controlled micro drone built to mimic a hummingbird's flight, using flapping-wing propulsion to hover and maneuver in tight spaces. It was developed in the United States by AeroVironment, Inc. under DARPA sponsorship.
What is the Nano Hummingbird's primary role?
It serves as a flapping-wing micro drone for urban reconnaissance, capable of hovering, flying in multiple directions, and entering indoor environments to conduct surveillance. Its tiny size and bird-like motion make it ideal for covert observation in confined spaces.
Who developed and funded the Nano Hummingbird?
AeroVironment, Inc. built the aircraft in the United States, with the project sponsored by the Defense Advanced Research Projects Agency (DARPA). It was also referred to as the Nano Air Vehicle (NAV) during its development.
How big and fast is the Nano Hummingbird?
It has a wingspan of just 6.3 inches and weighs only 0.67 ounces, making it one of the smallest functional aircraft ever built. Its top speed reaches 11 mph, which is modest but sufficient for its indoor surveillance mission.
Why is the Nano Hummingbird considered important in UAV history?
It demonstrated that flapping-wing micro-propulsion could produce a stable, controllable flight platform small enough to operate indoors, a capability no earlier drone had achieved. It proved the feasibility of bird-inspired flight for covert reconnaissance in urban and interior environments.
