Hop suitcase follows you around like a loyal dog  Never leave
your luggage unattended with a Hop suitcase, a bag that follows
around at your heels wherever you go.  Hop suitcase  The Hop

Congratulations, you have the world's most loyal piece of
luggage, the Hop. Hop is a suitcase that automatically follows
you around.  The suitcase is stocked with three receivers that
triangulate the user's phone's position over Bluetooth. A
microcontroller does the calculations and keeps it at a close
distance. The suitcase is security-minded. If it gets lost, the
user's phone will vibrate and Hop will lock itself up tight.
Hop uses a two-track caterpillar system with compressed air to
actually move. Much like a Dalek, it probably won't do well with
stairs.  The Hop suitcase is in prototype form at this point,
but it's an interesting peek at where luggage may go someday as
we slowly attain our Jetsons
