With the increasing adoption of mobile devices, wireless power transmission (WPT) technologies have garnered significant attention. Traditional methods like inductive power transmission are constrained by short range, prompting the exploration of laser-based optical wireless power transmission (OWPT) as a promising alternative. Previous OWPT systems relied on components such as cameras and Galvano mirrors for target recognition and beam steering, but their effectiveness was limited in scenarios with obstructed laser paths. To address these challenges, we developed a dual-arm robotic system integrating OWPT technology, controlled via TCP protocol and capable of dynamic, precise coordination.The system consists of two robotic arms positioned 70 cm apart on the same horizontal plane. One arm, controlled by an M5Stack chip, is equipped with a 532 nm laser (1 mW output), while the other, controlled by a Raspberry Pi chip, is outfitted with a solar panel to receive the transmitted power. A central computer acts as a server, transmitting synchronized coordinate data to the robotic arms via TCP protocol. This eliminates the need for additional sensors, simplifying hardware requirements while maintaining precise movement. A homogeneous transformation matrix is used to ensure accurate alignment based on the robotic arms’ relative positions.Experimental results demonstrated the system’s ability to achieve stable and continuous power transmission in a 2D plane. As shown in Figure 2, the system effectively maintained alignment, enabling successful energy transfer. The results validate the feasibility of integrating dual-arm robotic systems with OWPT technology for precise, dynamic applications, laying the groundwork for future advancements in flexible and scalable wireless power delivery systems.
