On August 25 and 26, 2025, the Department of Electrical and Electronic Engineering (EEE) participated in the 58th Joint School Science Exhibition at the Hong Kong Central Library. Our EEE student helpers presented two cutting-edge technologies in robotics and wireless power transfer, drawing strong interest from visitors and enhancing the visibility of HKU EEE.
The first exhibit featured an AI-assisted autonomous mobile robot capable of navigating complex environments without human intervention. Powered by advanced sensors, real-time data processing and machine learning algorithms, the smart robots can dynamically avoid obstacles and perform object recognition tasks such as automatically collecting ping pong balls and interfacing as a companion dog. This demonstration showcased how AI can address practical challenges, enhance quality of life, and contribute to sustainable development.
The second exhibit presented our patented multicoil wireless charging technology, which overcomes the limitations of traditional single-coil systems that can only charge one device at a time. By integrating an array of overlapping coils with novel inverter topologies, our solution enables fast, efficient and simultaneous charging of multiple electronic devices. It also offers freedom of positioning, allowing users to place devices anywhere on a charging pad or mat for greater convenience and flexibility.
Together, these technologies embody our commitment to advancing AI-driven smart automation and intelligent wireless power solutions, paving the way for a smarter and more connected future.
Last but not least, we extend our deepest thanks to the Faculty for their generous and unwavering support.
