A robot suitcase

                             

If you love travelling and you are keenly interested, what the future travel accessories will look like, imagine a suitcase that follows you at a permanent distance during your journey. The Hop is a new prototype suitcase, which has receivers that communicate with your smartphone to keep your luggage rolling along with you — hands free. A microcontroller counts the suitcase’s position relative to the phone, and keeps the case moving on its caterpillar tracks based on compressed air.In case the signal is lost the suitcase locks itself and a vibration is sent via the phone to alert the user. It is possible to program the bags to follow one another or to be controlled together by any staff, handling your luggage.
