Robot guide dog debuts in China amid severe lack of furry counterparts

A Chinese defense industry research facility has unveiled what it claims is the world's first wheeled and legged robot designed as a guide dog for visually impaired individuals, signaling the country's growing interest in applying robotics and AI to civilian applications. The robot, named Xiaoyuan and developed by Hangzhou-based Zhiyuan Research Institute in collaboration with China North Industries Group, the nation's largest defense contractor, was showcased at the China Care and Rehabilitation Expo in Beijing.

The robot boasts both wheels for smooth navigation on flat surfaces and four legs to maneuver stairs, enabling visually impaired people to move independently. Its quiet wheeled movement is particularly advantageous for those who depend on their hearing to perceive their surroundings. Additionally, the robot can detect overhead obstacles like low-hanging branches, a challenge for conventional mobility aids such as walking sticks.

The robot's positioning accuracy reaches centimeter-level precision, with an error margin of less than 30 centimeters, while its obstacle-avoidance capabilities are at least 99% indoors and 96% outdoors. Xiaoyuan is integrated with services like disability federation systems, accessibility maps, and a remote assistance portal for volunteers, allowing users to request assistance remotely when necessary.

According to a report by state-run Xinhua News in May, citing the China Association of Persons with Visual Disabilities (CAPVD), China is home to over 17 million visually impaired individuals. However, the number of guide dogs in service in the country is limited to around 400, with each dog costing approximately 200,000 yuan (US$29,776) and requiring about a year to train.

The Zhiyuan Research Institute has forged strategic partnerships with disability groups in the eastern province of Zhejiang, its capital Hangzhou, and Inner Mongolia, initiating pilot deployments and trials at locations such as Hangzhou's metro system and shopping centers. Other developers in China are also exploring the potential of robotics and AI technologies.

For instance, Beijing-based AI Robotics and Hangzhou-based RoboCT have created exoskeleton robots employed in hospitals and rehabilitation centers to assist patients in regaining mobility.
