That’s the primary advantage to systems like the 100 drones Ikea currently commands across Europe. The little scanning drones can provide around-the-clock updates to inventory and reach heights humans and most robots can’t.

The drones, which have been branded with the blue and yellow color scheme, an Ikea logo and the familiar “Hej!” tagline, are produced by Verity. The firm has been popular with investors, thanks in large part to its Ikea partnership. The startup raised $32 million last March and another $11 million four months later.
