Travelmate is a true fully autonomous suitcase. It works seamlessly in crowds, doesn’t require any extra peripherals. All you need is the suitcase and your smartphone. Travelmate will follow you wherever you go. It can move vertically or horizontally with ease. You can put more items or perhaps another suitcase on top of Travelmate when it is traveling autonomously in horizontal mode. Travelmate navigates large crowds and is able to recognize and avoid objects as needed. Travelmate has a battery life of 4 hours when in full autonomous mode and up to 100 hours in stand by mode.
