At a rehab training center in Beijing, some elderly volunteers recently tested exoskeleton robots to experience assisted walking. [Soundbite] Hou Yu, resident: "It feels fine. The robot is helping me bend and lift my legs." [Voiceover] The company's engineers say they're working to expand the test sample and gather more data to adjust and further improve the product. [Soundbite] Zhang Hongye, assistant engineer, Beijing AI-robotics Technology Co., Ltd.: "The elderly users prefer a design that is simpler and easier to be put on, enabling them to dress themselves. Additionally, the volunteers felt that the device was a bit heavy, so we have planned to reduce its weight in future versions."
