Something of a cross between a security camera and a drone, the Aevena Aire Flying Robotic Assistant is a new type of homebound gadget. Using a ducted fan assembly for quiet flight, it has an arsenal of sensors that let it fly around autonomously, avoid obstacles from any angle, and automatically takeoff and land. Using it to take a picture is as easy as asking your Amazon Echo to do so — the Aire will take off, find you, and snap a shot with its built-in camera. You can also take control remotely using the companion app, and over-the-air updates such as automated security patrols and virtual home mapping will expand its capabilities further. It was designed to look non-threatening, and while it's not trying to be cute, it also doesn't look like the kind of robot that could be programmed to do you harm, either — so you can put any Terminator-style worries to rest.
