Luggage are unwieldy, either because their size, shape or weight. And no matter how light your suitcases are, they still need to be carried around – probably the most laborious task of the the trip. But what if you could go hands-free and have the luggage follow you? Like a dog that follows his master, Hop is a robotic suitcase that will follow you.

Hop pairs with your smartphone via Bluetooth, calculates the phone's position and while keeping a constant distance, follows it thanks to a two caterpillar track system. And if the signal is lost, your phone is alerted and Hop locks itself.

Now it doesn't seem to be swift or sturdy enough to keep up with the fast-walking at the airport, but the concept seems like a fun idea.
