At the 2026 Beijing Yizhuang Humanoid Robot Half Marathon, a robotic guide dog named “Tutu” made its first public appearance, steadily accompanying visually impaired runner Wang Zihao through a complex environment and bringing technological warmth to the speed-oriented competition. During the on-site demonstration, “Tutu” used its onboard cameras and LiDAR to sense the surrounding environment, and alerted users to obstacles through vibrations from its guide cane and voice prompts. Its navigation strategy prioritizes finding continuous passable routes rather than relying solely on tactile paving. Technically, the robot is equipped with a self-developed end-to-end visual-language navigation foundation model and integrates Amap traffic big data, enabling it to predict traffic lights and congestion beyond its visual range. Statistics show that China has more than 17 million visually impaired people, yet only about 400 traditional guide dogs are in service nationwide. Due to high costs and long training cycles, embodied intelligent products such as “Tutu” are opening up new possibilities for inclusive travel.
