Abstract

ABSTRACT In this paper, a wireless charging system that can perform coil capacity optimization and dynamic protection is proposed for mobile robots. Poor wireless charging performance might be obtained because of the inability to achieve reliable capacity estimation and effective charging detection; therefore, in this study, suitable solutions were identified for capacity estimation and effective charging detection. First, resonance analysis was conducted on a systematic flexible coil design to maximize its charging capacity. Second, a dynamic protection mechanism was developed to handle unexpected charging mistakes caused by misalignment. Third, a pickup terminal feedback system integrated with a Bluetooth chip and microprocessor unit was embedded to maintain the requisite output voltage. This system was validated through simulations and hardware implementations. The experimental results indicate that a setup based on the proposed design delivers a power of 3.2 kW at an efficiency of 91.4%, which confirms the efficacy and feasibility of the proposed approach for robot charging.

考虑容量优化和动态保护的移动机器人无线电力传输

提出了一种能够对移动机器人进行线圈容量优化和动态保护的无线充电系统。由于无法实现可靠的容量估计和有效的充电检测，可能导致无线充电性能不佳;因此，本研究为容量估算和有效的充电检测找到了合适的解决方案。首先，对柔性线圈的系统设计进行了共振分析，使其充电容量最大化。其次，建立了一种动态保护机制，以处理因不对准引起的意外装药错误。第三，嵌入一个集成了蓝牙芯片和微处理器单元的拾取终端反馈系统，以维持所需的输出电压。该系统通过仿真和硬件实现进行了验证。实验结果表明，基于该设计的装置可提供3.2 kW的功率，效率为91.4%，验证了所提出的机器人充电方法的有效性和可行性。
