The Nano Air Vehicle, a DARPA-funded hummingbird-like demonstrator robot made by AeroVironment, flaps its wings to fly in any direction. The remote-controlled Nano can hover with precision like the real bird, and it can fly clockwise and counterclockwise. It weighs 19gm (0.67oz), including batteries, video camera, motors, and communications systems, and it has a wingspan of 16cm (6.3 inches). Its size and weight are within the range of real hummingbirds, and, like them, it uses its wings for control and propulsion. The Nano can hover continuously on its own power source for eight minutes. It can shift from hovering to a forward flight speed of 17.7kph (11mph). While hovering, the Nano can tolerate side wind gusts of up to 8kph (5mph) without losing more than 1m (3.28 feet) of altitude. (Source: AeroVironment)
To me, the 2013 penny feels like it's made out of a different, lighter material. The first time I held one, I thought it was a fake. I couldn't find anything online, however, that indicates it's made of different material.
