Hop is a suitcase that follows the user. Represents the next generation of luggage, the following. 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.
