Thanks to this new hands-free suitcase, carrying around heavy luggage may soon become a thing of the past. Designed by Israeli company NUA Robotics, this “smart” suitcase can follow you everywhere you go.

The carry-on suitcase, now a prototype(³ûÐÎ), connects to a smartphone app by means of bluetooth. It has a built-in camera sensor£¨´«¸ÐÆ÷£©that can “see” you and follow you around on flat floors. It comes with an anti­theft alarm to prevent someone carrying it away when you’re not looking.“It can follow and carry things for people around while communicating with their smartphone, and avoiding bumping intoobjects,” explained Alex Libman, founder of NUA Robotics.“We’re combining sensor network, computer vision, and robotics. So if you download our app, press the ‘follow me’ button, the luggage recognizes its user and knows to follow and communicate.”

NUA is still testing the products and trying to improve features, but they hope to make the suitcase available to customers in a year’s time. If it proves successful, they want to use the bluetooth pairing technology on lots of other products, like shopping carts at the supermarket. These products are especially meant to be useful to the physically disabled and elderly.“Any object can be smart and robotic£¬” Libman told Mashable.“We want to bring robots into everyday life.”

The Israeli tech company made it clear that the finished product will look just like a common suitcase. They’re planning to partner with a carry­on luggage maker, since the product that makes it “smart” weighs just 2.5 pounds and can be fitted on old­fashion luggage.

With NUA’s smart suitcase, carrying around heavy luggage isn’t a burden. But how their invention will handle tough blocks like stairs? It will be interesting to wait.
