Wireless charging for humanoid robots

An Israeli startup, CaPow, is revolutionizing the field of robotics by exploring the use of wireless charging technology to reduce the size and weight of batteries used in humanoid robots. This innovative approach aims to enhance the efficiency and autonomy of robots in various applications.

CaPow has developed an RF energy transfer system that can be seamlessly integrated with simple sheets of metal on the floor or even conductive ink, providing a versatile solution for charging robotic systems. According to Prof. Mor Peretz, co-founder and CEO of CaPow, "Humanoid robots will definitely be the next growing market to achieve fully autonomous warehouses," highlighting the potential impact of this technology.

One of the key advantages of the CaPow system is its ability to power humanoid robots through their feet, offering a unique and efficient charging method. This approach not only streamlines the charging process but also contributes to the overall mobility and functionality of the robots.

The 500W system developed by CaPow not only trickle charges the batteries but also has the potential to replace them with supercapacitors, further optimizing the performance of humanoid robots. By reducing the size and weight of the batteries required to power high torque motors, this system opens up new possibilities for more agile and versatile robotic designs.

Moreover, the CaPow system boasts features such as self-tuning capabilities and the ability to operate without precise alignment between charging plates, simplifying the charging process for users. Additionally, the system enhances battery longevity by regulating charging levels, leading to a potential threefold increase in battery life, as explained by Peretz.

With early approval in the US and ongoing pilot programs for unmanned ground vehicles (AGV) in industrial automation, the CaPow wireless charging system is poised to make a significant impact in the robotics industry. Anticipated CE approval for Europe in June further underscores the potential of this technology to drive innovation and efficiency in robotic applications.
