Description

Robot Charging Station Robot Charging Station The present invention relates to a charging station for a logistics robot used in a logistics field. Robots have been developed for industrial use to play a part in factory automation. Recently, however, the fields of robot application have been expanding further, with the development of not only medical and aerospace robots but also robots for use in daily life. Among industrial robots, automation using robots was prioritized because robots performing precision assembly tasks repeatedly execute the same movements at fixed locations without unexpected situations. However, the transportation charging sector, which includes driving—a charging area capable of making judgments regarding unexpected situations—has not yet seen active commercialization of robots. Nevertheless, the number of driving robots is increasing recently as the performance of surrounding perception sensors improves and computing power capable of rapidly processing recognized information to respond is enhanced. Industrially, robots responsible for transportation functions are attracting attention, and competition is intensifying day by day. Dozens of robots are operated in logistics sites, and considering charging and usage times, the number of chargers required is approximately one-third the number of robots. Chargers are generally installed against walls, and as the number of chargers increases, they are arranged in a line along one wall of the logistics center, occupying a significant amount of space. Not only must a location for installing the charger be secured, but a forward space for the robot to move to the charger must also be provided; however, it is difficult to secure sufficient such space in existing logistics sites.
