Why lug a suitcase all over an airport when you can have one that moves along with you on its own. That’s the idea behind Ovis, luggage created by a Chinese company called Forward X Robotics. It comes equipped with cameras and uses facial recognition technology and a movement tracking algorithm to lock in on its owner and stick with her or him at a speed of six miles per hour. Ovis is even able to avoid collisions as it makes its way through crowds. To make sure it doesn’t stray, the suitcase comes with a smart wristband that vibrates if it gets more than six feet away. It also has two USB ports so it can serve as a charging station. But perhaps best of all, Ovis has embedded GPS, so you can always track it if it goes missing.
