High-efficiency Wireless Charging System for Logistics Robots.

This paper introduces a 1kW-class wireless charging system for battery charging of logistics robots. The DC-DC efficiency of the system is more than 90%, and it shows excellent characteristics in misalignment of the transmission and reception coils, heat generation, and load change. In addition, the function of detecting foreign objects and living things using image information was explored, and a platform for charging and controlling a number of robots was developed.
