Magnetic resonance coupling wireless power transfer (MRCWPT) is a wireless power transfer (WPT) technology that utilizes the resonant state of power transmission and reception circuits. Compared with the prevalent electromagnetic induction method, this approach facilitates the efficient transmission of substantial power over extended distances. However, this distance is limited to the approximate diameter of the transmission coil. Therefore, novel methods are required to overcome these limitations. Accordingly, we propose an automatic power-supply system using autonomous mobile robots (WPT-Robot) equipped with power-supply units that are compatible with MRCWPT. This concept has also been adopted and studied by other research groups. However, previous studies have not considered the application of WPT to mobile power supply targets. To address this issue, this paper proposes a tracking WPT system that enables the highly efficient WPT of mobile targets using a WPT-Robot.
