The latest assistive technologies — including rehabilitation equipment, prostheses, barrier-free vehicles, and devices for the visually impaired — were recently showcased at the Care & Rehabilitation Expo China 2025 in Beijing.
This year's event drew particular attention to a new wave of AI-powered assistive products. Among the highlights was Xiaolu the Guide Dog, an intelligent electronic guide dog developed by Professor Jiang Yueqiu's team at Shenyang Ligong University. Equipped with LiDAR and a large AI model, Xiaolu helps visually impaired users navigate obstacles autonomously, while offering intelligent indoor navigation, facial recognition, AI-powered voice interactions, and scene descriptions.
"We put significant effort into both the hardware and navigation algorithms," said Yang Wei, a teacher at the university's school of equipment engineering. He pointed to the small square on Xiaolu's head: a full-thread solid-state LiDAR with a scanning radius of 70 meters, that enhances scene recognition and route planning. A depth-sensing camera at the front enables forward-looking vision and facial recognition, while an additional LiDAR on its "chin" captures ground-level data.
If the sensors serve as Xiaolu's "eyes," the embedded AI model acts as its "brain." "Through its algorithms, Xiaolu can identify obstacles and plan routes accordingly," said Yang. "Every step it takes is guided by this intelligent brain, making navigation safer and more flexible."
There is a pressing need for such innovations. China has more than 17 million visually impaired people, yet only about 400 guide dogs nationwide, according to the China Association of Persons with Visual Disabilities. Electronic guide dogs like Xiaolu could help close this gap and make "one guide dog per person" a realistic goal.
AI-assisted devices at this year's expo extended far beyond vision-related technologies. "The products on display not only cover a wide range of categories but also provide support for people with different needs, such as the visually impaired, hearing impaired, and physically disabled," said Zhang Hongtao, deputy director of the National Assistive Devices and Technology Center for Persons with Disabilities.
For those with hearing impairments, real-time transcription and speech-to-text conversion are becoming standard features on phones. When a call comes in, the caller's words appear instantly on-screen as text, while responses typed by the user can be converted into speech and relayed to the other party, making communication far more accessible.
