One of the more annoying aspects of traveling is lugging a heavy suitcase around with you. Fortunately, in the future that burden might be lifted off your shoulders and placed on the capable shoulders of robots.
That's because a Russian company is developing a robotic suitcase that doesn't require you to pull it around. Instead, it follows you wherever you go, acting like a little companion that just so happens to be loaded up with all your clothes. You simply carry a card around with you, and using " its robotic brain, internal gyroscope, light detectors and both sound and infrared sensors" to follow you around. You can preorder one now for $2,000 if you're feeling trusting.
