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 is the technological equivalent of Mary s little lamb - it will follow you everywhere you go. 多亏这种新型智能行李箱解放了人们的双手，搬运沉重的行李箱将很快成为历史。以色列灵性机器人公司研发出一种智能行李箱，它就像玛丽的小羊羔一样，主人走到哪它就跟到哪。 The carry-on suitcase, currently a prototype, connects to a smartphone app via bluetooth. It has a built-in camera sensor that can "see" you and follow you around on flat surfaces like airport floors. It comes with an anti-theft alarm to prevent someone snatching it away when you are not looking, and, for the icing on the cake, it has a backup battery that you can use to charge all your devices. "It can follow and carry things for people around while communicating with their smartphone, and avoiding obstacles," explained Alex Libman, founder of NUA Robotics. "We are combining sensor network, computer vision, and robotics. So if you download our app, press the "follow me" button, the luggage recognizes the specific user and knows to follow and communicate." NUA is still testing the device and trying improve features like speed and customization, 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 to automate lots of other devices, like shopping carts at the supermarket. These devices 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." |
