  "description_excerpt": "Embodiments disclosed herein relate to smart self-driving systems with side follow and obstacle avoidance.\n\nTravelers are often required to transport luggage across long distances, such as within long corridors of airport terminals. Transporting luggage may be inconvenient, stressful, and require undesirable levels of physical exertion. Even luggage that can be rolled on wheels has to be pulled or pushed, which can strain the arms and back of a person transporting the luggage. Some developers have incorporated electronics and motors into their products to provide self-driving luggage. However, current self-driving luggage designs follow from behind and out of the sight of the user, and are limited in their maneuverability to avoid obstacles, especially when being used in crowded places like airports, hotels, or a busy sidewalk.\n\nTherefore, there exists a need for new and improved smart self-driving systems.\n\nA smart self-driving system comprising a body; and one or more proximity sensors coupled to the body and configured detect an object moving in a given direction while the body is in a side follow position next to the object.\n\nFIG. 1 is a perspective view of a smart luggage system according to one embodiment.\n\nFIG. 2 is a perspective view of a smart luggage system according to another embodiment.\n\nFIG. 3 is a plan view of the smart luggage system in a side follow position on the side of a user according to one embodiment.\n\nFIG. 4 is a plan view of the smart luggage system in the side follow position and showing the user within a predetermined area as detected by the smart luggage system according to one embodiment.",
