This category stems from the old expendable definition and includes hand‐launched as well as small UAVs that have some type of launcher (could be hand‐launched). It is not officially defined by the JPO as a class of UAVs, but numerous demonstrations and experiments have been conducted over the past ten years.

These UAVs are exemplified by the electric‐powered Raven and Bayraktar mini‐UAVs in the selection of UAV examples earlier in this chapter. The Wasp UAV described among the previous examples is another example of a UAV at the upper limit of what might be called a “mini”‐UAV. The ANAFI Parrot can be considered as a mini‐UAV where it has a mass of about 0.5 kg, equipped with two 4K 21‐megapixel cameras, and can fly for about 32 minutes.

Another example for this class is the HR quadcopter, which has four electric engines, dimensions of 7.1 in × 6.7 in × 1.5 in, and a takeoff mass/weight of about 120 g (4.23 oz). It is equipped with a 1080P HD Camera and can take aerial photos/videos, with the built‐in WiFi module to broadcast a live video on a mobile device.
