在智能空间的概念中，移动机器人的电池容量需求和自我定位任务可以通过周围空间的无线电力传输和位置感知等辅助来缓解。基于磁共振耦合的无线电力传输有效范围约为天线直径，有望适用于移动机器人充电。如果还可以实现基于磁共振耦合的位置传感，那么单台设备就可以同时实现无线电力传输和位置传感，这是一个合理的系统。因此，本文介绍了一种基于磁共振耦合的新型位置传感器的提出和实验考虑。该传感器由安装在地板下的发射机阵列天线和内置在目标上的目标天线组成。在这里，可以使用开关单元从阵列天线中选择单个发射机天线。与其他传感器系统有两大不同。首先，几乎同样的设备也可以实现无线电力传输。其次，可持续的无电池位置传感是可能的，因为目标不需要任何电池。这是可能的，因为位置传感是基于反射系数，可以通过发射机天线侧测量。通过将反射系数计算得到的天线间耦合系数与天线间耦合系数和位置数据库相匹配来估计天线的位置。最后，通过实验对位置传感器的性能进行了评价。
In the concept of Intelligent Space, the battery capacity requirements and tasks for self localization in the mobile robot could be relieved by assistance such as wireless power transmission and position sensing from the surrounding space. Wireless power transmission based on magnetic resonance coupling has a effective range of about antenna diameter which is expected to be suitable for charging mobile robots. If the position sensing based on magnetic resonance coupling is also possible, both wireless power transmission and position sensing could be possible by single equipment which is a reasonable system. Therefore, this paper describes the proposal and experimental consideration of novel position sensor based on magnetic resonance coupling. The proposed sensor is composed by transmitter array antenna implemented under the floor and target antenna built into the target. Here, a single transmitter antenna can be selected from the array antenna using the switching unit. There are two big differences from the other sensor systems. First is that the wireless power transmission could be also possible by almost the same equipment. Second is that the sustainable battery-less position sensing is possible since the target does not require any battery. This is possible since the position sensing is based on reflection coefficient which could be measured by transmitter antenna side. The position is estimated by matching the coupling coefficient between antennas calculated from the reflection coefficient with the database of coupling coefficient and position. Finally, the performance of the position sensor is evaluated through experiments.
