Suitcase that follows you wherever you go without you touching it

                          

The 'following suitcase' is guided by the Bluetooth signal on your smart phone, The phone signal is received by three sensors built inside the luggage and if there is no signal on the phone, the suitcase locks itself and vibrates the owner's phone. Interesting, isn't it? But the bag seems to be moving very slowly though. What if the owner was in a hurry or somebody snatches it behind you? Abegi... I'd rather buy lift a bag.  However I think it would be very useful for people with special needs such as wheelchair users. See how it works below
