    • A system achieves seamless localization for a plurality of robots when first some robots moves to a shadow area where GPS signals are not received while remaining second robots receives the GPS signals, by performing an absolute localization for the second robots using the GPS signals; and performing an absolute localization for the second robots using the GPS signals; performing a relative localization for the first robots based on the second robots, thereby determining an absolute location of the first robots. Further, when the second robots move to the shadow area where the first robots have been moved, the system performs the seamless localization by determining a relative location of the second robots based on the first robots on which the relative localization has been performed, thereby determining an absolute location of the second robots based on the relative location of the second robots.
    • 当第一个机器人移动到没有接收到GPS信号的阴影区域,而剩下的第二机器人接收到GPS信号时,通过使用GPS信号执行第二机器人的绝对定位,系统实现多个机器人的无缝定位。 并使用GPS信号对第二机器人执行绝对定位; 基于第二机器人执行第一机器人的相对定位,从而确定第一机器人的绝对位置。 此外,当第二机器人移动到第一机器人被移动的阴影区域时,系统通过基于执行了相对定位的第一机器人确定第二机器人的相对位置来执行无缝定位,从而确定 基于第二机器人的相对位置的第二机器人的绝对位置。
