Shanghai Jiao Tong University Develops Six-Legged Guide Robot to Aid Visually Impaired

Researchers at Shanghai Jiao Tong University in China have unveiled a six-legged guide robot designed to assist visually impaired individuals. This innovative solution addresses the significant shortage of guide dogs in China, where only 400 guide dogs are available for approximately 17.31 million visually impaired people.

The robot, developed by Professor Gao Feng and his team from the School of Mechanical Engineering, is equipped with advanced features to traverse complex environments. It can identify and avoid obstacles, climb stairs, and recognize traffic lights—a capability that real guide dogs, which are colorblind, lack. The robot responds to human voice commands within a second, enhancing its usability for visually impaired users.

This development has significant implications for the independence and mobility of visually impaired individuals, particularly in countries with limited access to guide dogs. Technology advancements could reduce waiting times for guide dogs and improve the overall quality of life for millions of people worldwide.

One of the standout features of this guide robot is its multisensory perception system. This system combines natural language comprehension and speech recognition with force-feedback canes, allowing users to control the robot effectively. The robot employs advanced machine learning algorithms to automatically avoid both static and dynamic obstacles, ensuring high stability and safety.

Professor Gao Feng emphasized the robot's role in providing independence to visually impaired individuals. "We believe our robot will function as a 'pair of eyes' for visually impaired people," he stated. The primary task of the robot is to establish effective communication with blind individuals, enabling it to understand the user's intentions while maintaining coordinated movements.

The guide robot is currently undergoing field testing, with 20 units already ordered. This testing phase is essential to ensure the robot's reliability and effectiveness in real-world scenarios. Feedback from users will be instrumental in making necessary adjustments, such as adding more voice prompts to inform users of the robot's actions in advance.

The six-legged design of the robot provides extra stability, ensuring it remains steady and reliable even on uneven terrains. The robot can walk at a maximum speed of three meters per second while maintaining a stable walking state with minimal noise. Additionally, it can memorize routes indefinitely and does not require a constant internet connection to function.

Incorporating multiple sensors, including laser radar, the robot improves perception accuracy in complex environments. This multi-sensor data system includes radar and inertial sensors to reduce errors and ensure accurate positioning. These features make the robot a highly adaptable and reliable guide for visually impaired individuals.

The development of this guide robot marks a significant advancement in assistive technology for visually impaired individuals. As it undergoes further testing and refinement, it holds the potential to provide a reliable and stable solution, reducing the waiting times for guide dogs and enhancing the independence and mobility of those who need it most.
