However, RFID stands for Radio Frequency Identification, and is also called as Electronic Label. It goes through radio signals to identify specific targets, and reading and writing information, as well as don't need identity system and specific targets to create such as electronic, optics or machinery. Properties of wireless communication, space-penetrating, information tracking and real-time location system/ RTLS will apply for increasing the system capability of safety and protection to Robot.

而「RFID， Radio Frequency Identification 」称之为「无线射频识别」，又称「电子标签」，是一种通信技术，可透过无线电讯号识别特定目标并读写相关资料，而无需识别系统与特定目标即可建立含电子、光学或机械接触，其特性：无线通讯、空间穿透性、资讯历程可追踪与「即时定位系统 RTLS， Real Time Location System」等，必然将成为机器人、机械手臂安全设计与防护的新应用。
