Those of you who travel around a lot are familiar with the idea of carrying your suitcase and luggage around. Wouldn’t it be nice if your bags could follow you? The Hop! is an exciting suitcase that goes everywhere you go. You won’t have to carry it yourself though. It is powered by compressed air with a set of caterpillar tracks. The suitcase locks onto your cellphone signal and finds your position. When it gets lost, this locks itself down and vibrates your phone to alert you. A pretty exciting idea for travelers.
