Remember when suitcases were replaced, seemingly overnight, by those much-more convenient pulley-wheelie bags?
Get ready for it to happen again - only this time your luggage is going wireless.
The Hop suitcase is a new type of baggage which will follow you around an airport without you having to pull it at all.
The device is named after 'bellhops', a word used to describe those people who used to pull your bags around hotels (until they were made redundant by this bag, of course).
The makers say on their website:
"The suitcase contains three receivers that are able to receive, identify and triangulate different signals coming from the user's cell phone. A microcontroller interprets these signals calculating the phone's position regarding to the suitcase. The same microcontroller operates a caterpillar system based on compressed air, which follows the user at a constant distance."
They add that if the signal is lost the bag will ock itself, and might be able to speed up the entire process of travelling through an airport.
