Anybody who's read Terry Pratchett (https://goo.gl/rgv8PE) knows that Rincewind (https://goo.gl/Jdu3UH) is often saved by his Luggage that keeps following him around. Travelmate now has a "fully autonomous suitcase that can go anywhere" (https://goo.gl/Cqqcir) - check it out.
Not entirely convinced yet that it is truly indestructible (I bet United could really break it - https://goo.gl/aXB3NW) or that it can travel across dimensions (just yet) but it is a good start :D
